[Mollusca • 2020] Craspedotropis gretathunbergae • A New Species of Cyclophoridae (Gastropoda: Caenogastropoda), discovered and described on A Field Course to Kuala Belalong Rainforest, Brunei


Craspedotropis gretathunbergae 
Schilthuizen, Lim, van Peursen, Alfano, Jenging, et al., 2020


Abstract
Background: 
Terrestrial Caenogastropoda form an important but threatened component of the Borneo tropical rainforest malacofauna, where the group is nearly as rich in species as the Stylommatophora. They are, however, more sensitive to drought, temperature extremes and forest degradation.

New information:
On a field course at Kuala Belalong Field Studies Centre in Brunei Darussalam (Borneo), a new caenogastropod species, belonging to the genus Craspedotropis, was discovered by the course participants. The participants decided to name the species Craspedotropis gretathunbergae n. sp., in honour of the climate change activist Greta Thunberg, as caenogastropod land snails, such as this species, are likely to suffer because of climate change.

Keywords: Land snails, Borneo, lowland dipterocarp rainforest, new species

Craspedotropis gretathunbergae, sp. n.

Nomenclature: Craspedotropis Blanford 1864 sensu Vermeulen (1999). 
Type species: Craspedotropis cuspidata (Benson 1851)

Diagnosis: Amongst the Bornean cyclophorids, Craspedotropis gretathunbergae n. sp. is most similar to C. borneensis (Godwin Austen 1889), which, however, is somewhat less slender, has 7 - 9 spiral ribs and more broadly reflected apertural lip. In addition, the operculum of C. borneensis has raised whorl margins, which is not the case in C. gretathunbergae n. sp. Other Asian species, with which the new species may be confused, are: (i) Cyathopoma conoideum Sykes 1898, which has a more slender shell and the spiral ribs arranged in a different pattern, with the second rib located just above the suture; (ii) C. sivagherrianum Beddome 1875, which is smaller, has 7 spiral ribs and a nearly closed umbilicus; (iii) C. beddomeanum Nevill 1881, which has more (7 - 8) and more prominent, spiral ribs, more globular whorls and a rounder aperture; (iv) C. procerum Blanford 1868, which is stockier, has 9 - 12 spiral ribs and a peristome that is strongly thickened by folds.

Etymology: We name this species in honour of the young climate activist Greta Thunberg, because caenogastropod microsnails from tropical rainforests, like this new species, are very sensitive to the droughts and temperature extremes that are likely to be more frequent as climate change continues. Via mutual contacts, we have approached Ms. Thunberg and learned that she would be 'delighted' to have this species named after her.

Following Recommendation 51C of the Code (ICZN 1999), if it is desired that authorship of the name be included as part of the name, instead of listing all authors, the species can be referred to as Craspedotropis gretathunbergae Schilthuizen et al., 2019, provided that all authors of the name are cited in full elsewhere in the same work, either in the text or in a bibliographic reference.

Distribution: Borneo: Brunei Darussalam: Temburong District: Ulu Temburong lowland rainforest.

Ecology: In tropical mixed dipterocarp lowland rainforest. All individuals were found alive at the foot of a steep hill-slope, next to a river bank, foraging at night on the upper surfaces of green leaves of understorey plants, up to 1 m above ground level.

Taxon discussion: 
The generic classification of minute cyclophorids in Southeast Asia is somewhat confused. The genera Craspedotropis Blanford 1864, Cyathopoma Blanford 1861 Blanford and Blanford 1861, Jerdonia Blanford 1861 (Blanford and Blanford 1861; sometimes considered a subgenus of Cyathopoma) and Ditropopsis Smith 1897 appear poorly defined and may be partly overlapping or synonymous (Vermeulen et al. 2015, Vermeulen 1999). In its general shell form (a tall conical shell with spiral ribs), the present species is similar to several species of Cyathopoma (e.g. the South Asian C. conoideum Sykes 1898, C. sivagherrianum Beddome 1875, C. beddomeanum Nevill 1881 and C. procerum Blanford 1868) and Craspedotropis, especially C. borneensis (Godwin Austen 1889), known from Sarawak. Given the geographical proximity of the latter, we have tentatively placed the new species in the same genus, Craspedotropis.

Discussion:  
All work described in this paper (fieldwork, morphological study, microphotography, taxonomic description and diagnosis) was carried out in a field centre with basic equipment and no internet access, by untrained ‘citizen scientists’ guided by expert scientists, on a 10-day taxon expedition. While we are aware that this way of working has its limitations in terms of the quality of the output (for example, we were unable to perform dissections or to do extensive literature searches), the benefits include rapid species discovery and on-site processing of materials.

[Mammalogy • 2020] Mirostrellus joffrei • A New Genus of Vespertilionid Bat: The End of A Long Journey for Joffre’s Pipistrelle (Chiroptera: Vespertilionidae)


Mirostrellus joffrei (Thomas, 1915)

in Görföl, Kruskop, Tu, Estók, Son & Csorba, 2020. 

Abstract
Knowledge as to the taxonomic status of enigmatic bat species often is hindered by limited availability of specimens. This is particularly true for aerial-hawking bats that are difficult to catch. One such species, “Hypsugojoffrei, was originally described in Nyctalus due to its long and slender wings, but subsequently transferred to Pipistrellus, and most recently to Hypsugo, on the basis of morphology. Analysis of newly available material, which more than doubles the known specimens of this taxon, demonstrates that it is morphologically and genetically distinct from all other bat genera. We accordingly describe it as belonging to a new, monotypic genus. We provide a detailed description of its external and craniodental traits, measurements, and assessment of genetic relationships, including barcode sequences to facilitate its rapid identification in future. The new genus belongs to a group that includes the recently described Cassistrellus, as well as Tylonycteris, and its closest relative, Philetor. We also describe the echolocation calls emitted by members of the taxon in different situations, which may facilitate finding them in previously unsampled locations. Based on the new data, the species occurs from Nepal to North Vietnam and China, which suggests that it could be more widespread than previously thought.

Mirostrellus gen. nov.

Type species: Nyctalus joffrei Thomas, 1915.

Etymology: From the Latin “mirus” meaning “surprisemarvel,” which reflects that both the systematic position and the wide distribution of this bat (previously thought to be extremely rare) were pleasant surprises for the authors.

Diagnosis: A medium-sized vespertilionid, with a FA of 35.7–40.2 mm. The fifth finger of the wing is shortened (on average 20 mm shorter than the fourth finger) and the pelage is sparse and velvety. The supraorbital tubercles are well-developed, protruding for 1.47–1.76 mm measured from the lachrymal opening; the sagittal crest is barely visible, being only approximately 0.1 mm high. The upper canine is characterized by a developed posterior secondary cusp. The taxon has two upper and lower premolars and its lower molars are myotodont.

Geographic distribution: The only known species of Mirostrellus gen. n. has an Indomalayan distribution, ranging from Nepal, NE India (Sikkim, Meghalaya), through the northern part of Myanmar, to North Vietnam (Saikia et al. 2017). In the National Museum of Prague (Czech Republic), four hitherto unreported specimens from western Yunnan, China (Zao Teng He, ..., 1,451 m a.s.l.), were revealed by SVK. The species probably also occurs between these localities as it is difficult to capture and so may be missed during faunal surveys (Fig. 10).

[Ichthyology • 2020] Careproctus shigemii • A New Species of Careproctus (Cottoidei: Liparidae) from the Sea of Okhotsk and A Redescription of the Blacktip Snailfish Careproctus zachirus


Careproctus shigemii
Matsuzaki, Mori, Kamiunten, Yanagimoto & Kai, 2020


Abstract
A new snailfish, Careproctus shigemii, is described on the basis of three specimens collected in the southern Sea of Okhotsk, off Hokkaido, Japan. The new species has previously been confused with Careproctus zachirus Kido 1985, known from the Aleutian Islands, eastern Bering Sea, the Pacific Ocean off southeastern Kamchatka and the northern Kuril Islands, and the southern Sea of Okhotsk off Hokkaido, Japan, because of their similar appearance, including a noticeably elongate pectoral fin extending beyond the anal-fin origin, the gill slit entirely above the pectoral fin, no opercular flap projection, one suprabranchial pore, and trilobed teeth. However, C. shigemii is clearly differentiated from C. zachirus in having dorsal and anal fins margined with black (vs. white margined dorsal and anal fins with a black submarginal band), and a black caudal fin (vs. pale pink caudal fin), when fresh. Careproctus shigemii differs additionally from C. zachirus in having the cephalic pore pattern 2-6-6-1 (vs. 2-6-7-1), 30–35 pyloric caeca (vs. 20–31), and a shorter pectoral fin lower lobe, 8.2–9.9% SL (vs. longer lobe, 15.9–25.6% SL). A large sequence divergence between C. shigemii and C. zachirus (0.028 in uncorrected p-distance) in the DNA barcoding region (COI) also supports the validity of each species. A redescription of C. zachirus is also provided on the basis of the holotype, paratypes and non-type specimens.

AMF-2-11-04-00-0031, paratype, 231.4 mm SL.

Careproctus shigemii sp. nov.
(New Japanese name: Otohime-Kon’nyaku-uo)

Distribution. Known only from the southern Sea of Okhotsk off Rausu, Hokkaido, Japan. Collection depths ranged from 200 to 300 m. By comparison, C. zachirus in the same area occupies depths of ca. 500–800 m.

Etymology. Named after the late Shigemi Fujimoto, a fisherman of Rausu, Hokkaido, Japan, who assisted our team in collecting various marine organisms, including the present new species, and contributed significantly to our efforts to understand the marine biodiversity of Rausu and Shiretoko Peninsula, a World Heritage Area.

[Phycology • 2020] Pyropia meridionalis • An Appraisal of the Genus Pyropia (Bangiales, Rhodophyta) from southern Africa based on A Multi-gene Phylogeny, Morphology and Ecology, including the Description of A New Species


Pyropia meridionalis M.M. Reddy, R.J. Anderson et J.J. Bolton

in Reddy, De Clerck, Leliaert, et al., 2020. 

 Highlights: 
• An appraisal of the genus Pyropia from southern Africa was carried out using an integrative taxonomic approach.
• A new, kelp-associated, species was described from the region.
• Species boundaries were confirmed for two other species of Pyropia endemic to the region.
• Species-level relationships of southern African Pyropia were considered in a global phylogenetic context.

Abstract
Since its reinstatement, the diversity of the genus Pyropia has never been fully assessed in the Benguela Marine Province in southern Africa (South Africa and Namibia), although it has been included in previous, more general biodiversity assessments. The aim of the present study was to revisit the diversity and identity of species of Pyropia from the region, using an integrative taxonomic approach, including a multigene phylogeny, morphological characterisation and ecological data. The phylogenetic affinities of southern African Pyropia to other species around the world were assessed using three unlinked loci (cox1, rbcL, nSSU rDNA). A species first collected on the South African coast ca. 60 years ago is described as a new species, Pyropia meridionalis, and extended descriptions and further information provided on the distribution and ecology for two previously described species endemic to the Benguela Marine Province: Py. saldanhae and Pyaeodis. Lastly, the identity and occurrence of Py. gardneri, a species widely distributed in North America, could not be confirmed in South Africa, while the cosmopolitan Pysuborbiculata likely occurs in the region but is currently lacking molecular data. The phylogenetic relationships between species from southern Africa and other species occurring in the Southern Hemisphere support the notion of historic connectivity in the Southern Ocean, but also indicate a much more complex historical biogeographical history as some clades are deeply divergent while others are more closely related.

Abstract
The 34 species of Australian Psilota are revised, with 26 new species described (Psilota aislinnae Young sp. nov., Psilota alexanderi Young sp. nov., Psilota apiformis Thompson and Young sp. nov., Psilota auripila Young and van Steenis sp. nov., Psilota azurea Thompson and Young sp. nov., Psilota bicolor Young and Ferguson sp. nov., Psilota brunnipennis Young sp. nov., Psilota calva Young sp. nov., Psilota darwini Young sp. nov., Psilota flavoorta Young and van Steenis sp. nov., Psilota fuscifrons Young sp. nov., Psilota livida Young and van Steenis sp. nov., Psilota longipila Thompson and Young sp. nov., Psilota mcqueeni Young sp. nov., Psilota metallica Thompson and Young sp. nov., Psilota nigripila Young sp. nov., Psilota occidua Young sp. nov., Psilota pollinosa Young and van Steenis sp. nov., Psilota purpurea Thompson and Young sp. nov., Psilota smaragdina Young sp. nov., Psilota solata Young and van Steenis sp. nov., Psilota spathistyla Young and van Steenis sp. nov., Psilota spinifemur Young sp. nov., Psilota viridescens Young and van Steenis sp. nov., Psilota xanthostoma Young sp. nov., Psilota zophos Young sp. nov.) and one new record for Australia (Psilota basalis Walker, 1858). Previously described Australian species are redescribed, with the males of Psilota auricauda Curran, 1925 and P. basalis (Walker, 1858) described for the first time. Six previously described species (Psilota erythrogaster Curran, 1926, Psilota hirta Klocker, 1924, Psilota queenslandica Klocker, 1924, Psilota rubra Klocker, 1924, Psilota rubriventris Bigot, 1885, and Psilota shannoni Goot, 1964) are morphologically indistinguishable from related species. P. erythrogaster, P. rubra, and P. rubriventris are therefore treated under the Psilota cuprea (Macquart, 1850) species complex while P. hirta, P. queenslandica, and P. shannoni treated under the Psilota tristis Klocker, 1924 species complex. Lectotypes for the following species are designated: Coiloprosopa nitida Macquart, 1850, Merodon muscaeformis Walker, 1852, Orthonevra basalis Walker, 1858, Psilota coerulea Macquart, 1846, and Psilota viridis Macquart, 1847.

 Abstract
Kaempferia aurora sp. nov. Noppornch. & Jenjitt., from Tak province near the Thailand‐Myanmar border, and K. caespitosa sp. nov. Noppornch. & Jenjitt., from Lampang province, northern Thailand, are described as new species of K. subgen. Protanthium (Horan.) Baker. Their diagnostic characters are compared with those of similar species. Detailed illustrations, photographs of dissected flowers, information on phenology, distribution and ecology, and preliminary conservation statuses are provided for both new species. An identification key to the species of Kaempferia subgen. Protanthium in Thailand is also revised and presented.

Keywords: anther crest, floral morphology, flowering phenology, Kaempferia auroraKaempferia caespitosa, new taxa


Kaempferia aurora Noppornch. & Jenjitt., sp. nov. 


Etymology: The specific epithet ‘aurora’ is derived from Latin and means dawn, referring to the anthesis time of the species. The flower is fully open and functional for a short period in early morning (06 a.m. to 07 a.m. at anthesis) and then immediately wilts within an hour.

Vernacular names: This species is named ‘Proh Fah Sang - เปราะฟ้าสาง’ [Proh = Kaempferia, Fah Sang = dawn] and ‘Dok Din Arun Rung- ดอกดินอรุณรุ่ง’ [Dok Din = flower which occurs on the ground, Arun Rung = dawn]. These names refer to the anthesis time of the species which is fully open in early morning. ‘Dok Din See Sanim - ดอกดินสีสนิม’ [See Sanim = brownish orange colour] and ‘Dok Din Umpun - ดอกดินอำพัน’ [Umpun = amber] refer to the color of wilted flower.


Kaempferia caespitosa Noppornch. & Jenjitt., sp. nov.

Etymology: The specific epithet ‘caespitosa’ refers to the clump‐forming or tufted habit of the species. This character state is rare in Kaempferia subgen. Protanthium.

Vernacular names: This species is named ‘Proh Pha Souk - เปราะผาสุก - ดอกดินผาสุก’ [Pha Souk = comfortable] and ‘Dok Din Mueang Ngao - ดอกดินเมืองงาว’ [Mueang Ngao = district name of type locality].

[Ichthyology • 2020] Ammoglanis obliquus • A New Psammophilic Species of the Catfish Genus Ammoglanis (Siluriformes, Trichomycteridae) from the Amazon River Basin, northern Brazil


Ammoglanis obliquus 
Henschel, Bragança, Rangel-Pereira & Costa, 2020


Abstract
Ammoglanis obliquus sp. nov., a minute catfish species reaching a maximum adult size of 15.5 mm, is described from the Rio Preto da Eva drainage in the central Brazilian Amazon. It is distinguished from all of its congeners in possessing an exclusive combination of character states, including the presence and number of premaxillary and dentary teeth, number of interopercular and opercular odontodes, presence of cranial fontanel, number of dorsal-fin rays, number of anal-fin rays, number of caudal-fin rays, number of pelvic-fin rays, number of pectoral-fin rays, absence of pelvic splint, antorbital morphology, and absence of supraorbital and autopalatine morphology. It is considered to be a member of a clade also including A. pulex and A. amapaensis due to the unique oral, antorbital, and autopalatine morphology. Ammoglanis obliquus is regarded as more closely related to A. pulex than to any other congener, as both species exhibit a similar colour pattern, an absence of the metapterygoid, and the presence of two finger-like projections on the chin region.

Key Words: Taxonomy, tropical rain forest, Sarcoglanidinae, systematics

Figure 1. Ammoglanis obliquus: UFRJ 12477, 14.1 mm SL (holotype): Amazonas river basin. A. Lateral left view; B. Dorsal view.

Ammoglanis obliquus sp. nov.

Diagnosis: Ammoglanis obliquus differs from all its congeners except A. pulex by the presence of seven diagonal rows of dark cromatophores forming a banded pattern on flank of live specimens (vs trunk with three longitudinal rows of dark chromatophores in A. diaphanus and A. amapaensis, or whitish with few minute dark chromatophores scattered on body in A. multidentatus), the absence of metapterygoid (Fig. 3; vs presence), and by the presence of two finger-like projections on chin region (de Pinna and Winemiller 2000: fig. 2b; vs absence). It is distinguished from A. pulex by the presence of dentary teeth (Fig. 4A; vs absence), the presence of premaxillary teeth (Fig. 4B; vs absence), by having 6+6 caudal-fin rays (vs 5+5), and by the absence of the pelvic splint (vs presence). It further differs from A. diaphanus, A. amapaensis, and A. multidentatus by the absence of the sesamoid supraorbital (Fig. 5, vs presence), by having fewer premaxillary teeth (3 vs 9–12 in A. diaphanus, 8–11 in A. amapaensis, and 10 or 11 in A. multidentatus), fewer dentary teeth (4 vs 8 in A. diaphanus, 7 or 8 in A. amapaensis, and 11–13 in A. multidentatus), and fewer dorsal-fin rays (total of 8 vs 10 in A. diaphanus, 9 in A. amapaensis, and A. multidentatus). It is distinguished from A. diaphanus and A. multidentatus by the presence of 6 pectoral-fin rays (vs 7 in A. diaphanus and 7 or 8 in A. multidentatus), and the presence of a scythe-shaped antorbital (vs antorbital straight, with its tip not curved mesially); from A. amapaensis, by the presence of a wide cranial fontanel (vs dorsal surface of the neurocranium totally ossified, without a fontanel; Mattos et al. 2008: fig. 4), absence of separate ossification of the anterior cartilage of autopalatine (vs presence); from A. multidentatus, by possessing fewer opercular odontodes (8–11 vs 15 or 16), fewer interopercular odontodes (5–8 vs 10 or 11), fewer anal-fin rays (total of 8 vs 9), and fewer pelvic-fin rays (total of 4 or 5 vs 6).


Distribution: Known only from its type locality in Rio Preto da Eva drainage, Amazonas river basin, northern Brazil.

Etymology: From the Latin obliquus, meaning oblique, referring to the conspicuous diagonal banded colouration pattern of living specimens.

Ecological notes: This species is known only from a small clearwater tributary of Preto da Eva river, which is a left margin tributary of the Amazonas river. Individuals were found associated with a sand-bank lying on the centre of an artificial widening of the main course, next to a road. The stream course margins were lined by gallery rainforest, and the water column was about 1 m deep with a weak current. The sand-bank was composed of coarse, yellow sand and with sparse patches of small banks of macrophytes. Capture was accomplished by scooping of the superficial layer of sand with fine hand-nets. Specimens of Potamoglanis Henschel, Mattos, Katz & Costa, 2018 and Ammocryptocharax Weitzman & Kanazawa, 1976 were frequently captured together with Ammoglanis obliquus.

Abstract
The taxonomic status of the previous record of Opisthotropis maculosa Stuart & Chuaynkern, 2007 from Guangdong and Guangxi, southern China, is revised based on the comparison of morphological and molecular data collected from the Chinese specimens and the holotype of O. maculosa from Thailand and O. haihaensis Ziegler, Pham, Nguyen, Nguyen, Wang, Wang, Stuart & Le, 2019 from Vietnam. Results reveal that the population from Shiwandashan Nature Reserve in southern Guangxi, China belongs to O. haihaensis, and represents the first national record for China; the populations from western Guangdong and southeastern Guangxi are described as a new species, Opisthotropis hungtai sp. nov. We suggest that O. maculosa should be removed from the Chinese herpetofauna checklist. The new national record of O. haihaensis and the description of the new species bring the total number of Opisthotropis to 13 in China.

Keywords: New national record, Opisthotropis hungtai sp. nov., southern China, taxonomy

Opisthotropis hungtai sp. nov.

Chresonymy: Opisthotropis maculosa Stuart & Chuaynkern, 2007: Yang et al. (2011) (part); Wang et al. (2017a), Ren et al. (2019).

Etymology: The species name “hungtai” refers to Professor Hung-Ta Chang (=Hong-Da Zhang, 张宏达), an outstanding botanist, who established the Tropical and Subtropical Forest Ecosystem Experimental Center in Heishiding Nature Reserve, promoting the development of ecological research in southern China. We suggest the English common name Hung-Ta Chang’s Mountain Keelback and the Chinese name Zhang Shi Hou Leng She (张氏后棱蛇).

Diagnosis: Opisthotropis hungtai sp. nov. is characterized by the following combination of characters: (1) TL 464.3–501.2 mm in adult males, 393.2–511 mm in females, (2) tail moderate, TaL/TL 0.20–0.26 in males, 0.19–0.22 in females, (3) internasal not in contact with loreal, prefrontal not touching supraocular, frontal touching preocular, (4) one preocular, one or two postocular(s), (5) temporals 1+1, (6) supralabials seven, the fourth and fifth in contact with eye; (6) maxillary teeth 16–18, (7) anterior pair of chin shields longer than or equal to posterior pair; (8) ventrals 170–189 (+ 2 preventrals) in males, 168–175 (+ 2 preventrals) in females, (9) subcaudals 76–98 in males, 69–84 in females, (9) nasal cleft pointing to the second supralabial, (10) body scale in 15–15–15 rows, (11) body scales smooth, tail scales smooth or indistinctly keeled, (12) chin shields yellow with brownish black mottling, and (13) body and tail dorsum dark, each with a light spot per scale.

Distribution and habits: Opisthotropis hungtai sp. nov. is currently known from Heishiding Nature Reserve (ca 300 m a.s.l.) and Dawuling Forestry Station (ca 900 m a.s.l.) in western Guangdong, and Mt. Wuhuang (ca 500 m a.s.l.) in southeastern Guangxi.

The specimen from Mt. Wuhuang was collected in a rocky stream. Besides, specimens from Heishiding Nature Reserve were found in pelitic gutterways along the dirt path, and specimens from Dawuling Forestry Station were collected in a pelitic stream. The collection sites were all surrounded by well-preserved, dense deciduous forest.

Abstract
Based on two adult specimens collected in the Río León (Azuay, Ecuador), we describe a new highland species of a small crab-eating rat of the genus Ichthyomys Thomas (Rodentia, Cricetidae, Ichthyomyini). It is distinguishable from Ichthyomys hydrobates (Winge, 1891), the species phenetically closest to it, by its smaller size, bicolored tail (unicolored in I. hydrobates), broad and heavily fringed hindfoot (narrower and moderately fringed in I. hydrobates), and several craniodental traits (e.g. rostrum short broad; nasals anteriorly truncated; interorbital region narrow; supraorbital margins smoothly rounded; supraorbital foramina small, zygomatic plate very narrow; incisors opisthodont; length of M3 half that of M2). The new species occurs in the western Andes in southern Ecuador and is allopatric with Ichthyomys stolzmanni Thomas, 1893, which also has a bicolored tail but is larger. The new species brings the number of Ecuadorean Ichthyomys to four, Ecuador thus becoming the country with the greatest diversity of Ichthyomyini (four genera and eight species).

Ichthyomys pinei sp. n.  
Pine’s Crab-eating Rat or Rata Cangrejera de Pine

Etymology: This species is named in honor of Ronald H. Pine (Lawrence, KS, USA). Dr. Pine has engaged in vertebrate surveys in various countries in five continents, and has published numerous scholarly articles, mostly focused on Latin American bats, rodents and marsupials. The species epithet is formed from the surname “Pine”, taken as a noun in the genitive case, with the Latin suffix “i” (ICZN 31.1.2).
