[Botany • 2020] Lintersemina chucuriensis (Rubiaceae: Condamineeae) • A New and Enigmatic Genus from the Magdalena Medio Region of Colombia


Lintersemina chucuriensis H. Mendoza-Cifuentes, A. Celis & M.A. González

in Mendoza-Cifuentes, ... et González, 2020. 

Abstract
A new genus, Lintersemina (Condamineeae, Rubiaceae), with a single species, L. chucuriensis is here described, based on recent collections made during a biological exploration to the Magdalena Medio Region of Santander Department, central portion of Colombia. This region is of high interest for both the high endemicity of its flora and fauna and the critical conservation status of this biodiversity due to high levels of deforestation. Lintersemina is unique within the tribe Condamineeae for the following combination of characters: axillary, long-pedunculate inflorescences, loculicidal capsules with 1-2 seeds per locule, and large navicular seeds. Based on phylogenies obtained using plastid and nuclear sequence data, the genus is positioned in the Condamineeae (subfamily Ixoroideae), as a sister group to the genera Simira and Parachimarrhis. This new genus is only known from two localities at the foothills of the Yariguíes National Park, in the municipalities of El Carmen de Chucurí and Zapatoca, at 400–800 m elevation, in forest undercanopy, near streams. Threats of deforestation and a very low population density were assessed, and this species classified as Critically Endangered (CR) following IUCN criteria. Full description and illustrations are also included.

Type species:— Lintersemina chucuriensis H. Mendoza-Cifuentes, A. Celis & M.A. González 

Diagnosis:— This new genus is unique within the tribe Condamineeae by the following combination of characters: axillary, long-pedunculate inflorescences, ovary with 1–2 ovules per locule, loculicidal capsules, and large, terete, navicular (boat-shaped) seeds. Treelet. Leaves opposite, decussate, petiolate; petioles slightly thickened at the base; blade venation brochidodromous, with secondary veins ascending and arcuate. Stipules interpetiolar, readily caducous, only found at apical buds and youngest nodes, with colleters in adaxial surface, resinous. Inflorescences axillary, subterminal, corymbose cymes, pedunculate, many-flowered; with two types of bracts, the basal ones subtending the inflorescence leaf-like, the distal ones triangular. Flowers hermaphroditic, protandrous, 5- or 6-merous, actinomorphic, pedicellate, erect. Calyx persistent in fruit. Corolla aestivation left-contorted. Stamens included; anthers opening by longitudinal slits. Ovary 2-locular, placentation axile, ovules 1 or 2 in each locule; style included, with two stigmatic branches. Fruit a loculicidal capsule. Seeds >1 cm long, terete, navicular, with membranaceous structures along the raphe. A monospecific genus, endemic to Magdalena Medio Region of Colombia, growing in tropical rainforest. 

Etymology:— The name of this genus refers to its navicular (boat-shaped) seeds.

[Fungi • 2020] Amanita brunneofolia • A New Species and Two New Records of Amanita (Amanitaceae; Basidiomycota) from South Korea


Amanita brunneofolia J.W. Jo, H.S. Kim, Y.-N. Kwag & C.S. Kim

in Jo, Kwag, Kim, ... et Kim, 2020. 

Abstract
A new species of Amanita sect. RoanokensesA. brunneofolia, from South Korea, is described based on morphological and molecular evidences. The species is characterized by medium- to large-sized basidiomata, a greenish white pileus covered with brownish, floccose pyramidal volval remnants, an appendiculate margin, reddish brown lamellae, a long radicating stipe, and ellipsoid to elongate amyloid basidiospores. Based on both nrLSU and combined dataset (nrLSU, rpb2 and tef1-α), A. brunneofolia formed a monophyletic clade and clearly separated from other Amanita species. In addition, we describe two other Amanita species in A. sect. Roanokenses, namely, A. caojizong and A. sphaerobulbosa. This is the first report of these species for South Korea.

Tylototriton  errucosus: Nabhitabhata and Chan-ard (2005): 181.
Tylototriton uyenoi: Hernandez (2016): 168.



Diagnosis: The new species is placed in the genus Tylototriton by having the combination of dorsal  granules present; dorsolateral bony ridges on head present; knob-like warts (rib nodules) on dorsolateral body present; quadrate spine absent. Tylototriton  phukhaensis sp. nov. differs from  other congeners by having the following morphological characters: medium size, adult SVL 64.3 mm in male and 68.9–70.2 mm in females; skin rough with fine granules; sagittal ridge on head narrow, long, and distinct; vertebral ridge distinct and weakly segmented; rib nodules prominent; limbs long and thin;tips of forelimb and hindlimb overlapping when adpressed along body; tail thin.

Etymology: The specific epithet phukhaensisis derived from the name of Doi Phu Kha National Park, where the species occurs.

Distribution: The distribution of Tylototriton phukhaensis sp. nov.is currently only known from a single locality in atemporary  swamp in  the Doi Dong Ya  Wai  Mountain, Doi Phu Kha National Park,  Nan Province, northern Thailandat an elevation of 1,795 m  amsl (Fig. 7). The  Phu  Kha Mountain or Doi Phu Kha is one of the mountains located along the Luang Prabang Range that  consists of a series of high mountain ranges from Thailand to Laos (Fig.1). Thus, the range distribution of this species is expected to be wider.

[Paleontology • 2020] Schleitheimia schutzi • A derived Sauropodiform Dinosaur and other Sauropodomorph Material from the Late Triassic of Canton Schaffhausen, Switzerland

Abstract
Although sauropodomorph dinosaurs have been known for a long time from the Late Triassic of central Europe, sauropodomorph diversity and faunal composition has remained controversial until today. Here we review sauropodomorph material from the Canton Schaffhausen, Switzerland. The material comes from three different but geographically close localities and represents at least three different taxa. Apart from the common genus Plateosaurus, the material includes remains of two different large, robustly built sauropodomorphs. One of these is described as a new taxon, Schleitheimia schutzi n. gen. et sp., on the basis of an unusual ilium and associated axial and appendicular material. Schleitheimia represents a derived basal sauropodiform and possibly the immediate outgroup to Sauropoda, and thus is the most derived sauropodomorph known from the Late Triassic of Europe. These results thus highlight the diversity of sauropodomorphs in the Late Triassic of central Europe and further indicate widespread sauropodomorph survival across the Triassic-Jurassic boundary.

Schleitheimia n. gen.

Type species. Schleitheimia schutzi sp. nov.

Etymology. Genus name refers to the type locality at Schleitheim, Canton Schaffhausen, Switzerland.

Schleitheimia schutzi sp. nov.

Etymology. Species epithet honours the collector of the type material, Emil Schutz (1916–1974).

Holotype. PIMUZ A/III 550, partial right ilium.


Type locality and horizon. The type locality is Santierge (Fig. 1), a hill situated 900 m south of the church of Schleitheim in the Swiss Canton Schaffhausen (47° 44′ 30″ N, 8° 29′ 13″ S). The material, collected in the Bratelen Bonebed (“Rhät-Bonebed”), was most probably derived from the uppermost part of the ‚Zanclodonmergel‘(= Knollenmergel), now called Gruhalde Member of the Klettgau Formation, uppermost Norian (Jordan et al. 2016).

Diagnosis. The new taxon can be diagnosed by the following autapomorphies: medial brevis shelf of ilium developed as dorsoventrally broad, rounded ridge just below the mid-height of the iliac blade on the medial side that ends in a large, round expansion at the posterior end of the ilium; fourth trochanter of the femur very robust and arises gradually out of the posterior surface of the bone at about its mid-width towards its apex at the posteromedial margin; crista tibiofibularis of the femur exceptionally broad and only very slightly offset medially from the lateral margin of the shaft, so that no posteriorly facing shelf is present lateral to the crista.


Time-calibrated cladogram of basal sauropodomorph relationships (based on the unweighted analysis), showing the survival of numerous lineages (including sauropods) across the Triassic-Jurassic boundary

Conclusions: 
Fragmentary sauropodomorph remains from the probably Late Norian of Schaffhausen, Switzerland, that were long considered to represent the common central European genus Plateosaurus can be shown to represent a separate taxon of non-sauropodan sauropodomorphs, Schleitheimia schutzi. The recognition of this new taxon, together with an evaluation of other sauropodomorph material from the Late Triassic of Schaffhausen shows that at least three different basal sauropodomorph taxa were present in the Norian of Switzerland. Schleitheimia is a derived sauropodiform and might even represent the immediate outgroup to sauropods. In the context of a phylogenetic analysis, the new taxon indicates that the Triassic/Jurassic extinction event probably only had a minor effect on sauropodomorph evolution, and that the ascent of sauropods was delayed until the late Early Jurassic, when other basal sauropodomorph lineages perished in the Pliensbachian/Toarcian extinction event and gave way to an explosive radiation of that clade.

 Abstract
 We present a systematic revision of the Rentapia hosii complex based on morphological and bioacoustic data. In conjunction with genetic data from a previous study, our results show that populations from Peninsular Malaysia are distinct from the name-bearing population of R. hosii from Sarawak in terms of morphometrics, colour-pattern, and to a lesser degree, male advertisement call. Therefore, we describe the Peninsular Malaysian populations as a new species (Rentapia flavomaculata, new species) and provide a discussion on morphological variation among Bornean populations. 

Key words. bioacoustics, integrative taxonomy, morphology, systematics

Pedostibes hosii Barbour, 1938: 192.
Rentapia hosii Chan et al., 2016: 9.

Diagnosis. Rentapia flavomaculata, new species, can be differentiated from other congeners by the following combination of characters: adult females large (up to 105 mm SVL); dorsum relatively smooth; no distinct tubercles on dorsal aspect of nuchal region; in life, dorsal colour light green, ventral colour greyish-green; bright yellow spots on back, side of head, flanks, dorsal surface of limbs, gular, ventrolateral region, and chest; spots absent on top of head and sparser (sometimes absent) on back. In males, dorsal colouration uniform brown to reddish-brown with no distinct markings; venter light grey with no distinct markings; gular sac blackish; nuptial pad present on dorsal surface of thumb; single, internal subgular vocal sac.

Distribution. Rentapia flavomaculata, new species, is confirmed to occur throughout Peninsular Malaysia and southern Thailand (south of the Isthmus of Kra).

Natural history. All species in the Rentapia hosii group are typically arboreal and occur in lowland forests from 20–525 m a.s.l. (Inger, 1966). Females are encountered much less frequently than males and are usually observed during breeding, where they descend from treetops to breed in pools of water along small to moderately sized forest streams. Females have been observed perched on branches up to 25 m above ground in the forest canopy near fast-flowing rivers. Males call from elevated perches and multiple individuals can usually be heard along a single stretch of stream. In females, base colour changes relatively rapidly from light green to dark grey when handled, stressed, and preserved (Fig. 7A, B). Males can change from light to a darker shade of brown.

Etymology. The specific epithet is constructed from the Latin adjectives flavo (= yellow) and maculata (= spotted) in reference to the species’ diagnostic yellow spots.

[Ichthyology • 2020] Systematic Reappraisal of the Anti-equatorial Fish Genus Microcanthus Swainson (Teleostei: Microcanthidae), with Redescription and Resurrection of Microcanthus joyceae Whitley


Microcanthus joyceae Whitley, 1931

in Tea & Gill, 2020

Abstract
The taxonomy and classification of the microcanthid fish genus Microcanthus Swainson has been a subject of contention dating back to the 19th century. Its allopatric, disjunct anti-equatorial distribution across the Indo-West Pacific has resulted in the recognition of several nominal taxa, though these have been widely regarded as synonyms of Microcanthus strigatus (Cuvier). Following the results published in a companion study elsewhere by the authors, the taxonomy of Microcanthus and the validity of these nominal synonyms are herewith revised. Microcanthus strigatus is redescribed on the basis of 66 specimens from East Asia, Hawaii and Western Australia, and M. joyceae is resurrected and redescribed on the basis of 25 specimens from eastern Australia and the southwest Pacific. Microcanthus differs from other microcanthid genera in having the following combination of characters: dorsal-fin rays XI,15–17 (usually XI,16); anal-fin rays III,13–15 (usually III,14); pectoral-fin rays 15–17 (usually 16); scales ctenoid with ctenial bases present; lateral-line scales partially or heavily obscured by adjacent scales; and body pale in preservation with five horizontal dark stripes reaching the posterior edges of dorsal and anal fins, and base of caudal fin. The review is accompanied by a key to the genera of Microcanthidae.

Microcanthus Swainson

Etymology. The generic epithet Microcanthus is a combination of the Greek “mikros” for small, and “akantha” for thorn, alluding to the minute crenulations on the preopercle (Swainson 1839). 


Microcanthus strigatus (Cuvier in Cuvier & Valenciennes 1831)

Etymology. The specific epithet strigatus is the Latin for strigate, in having transverse bands or streaks of colour.

Microcanthus joyceae Whitley (1931) 

Etymology. The species is named after Joyce K. Allan, who provided Whitley with illustrations of this species for his original description. To be treated as a noun in the genitive case. While Whitley did not provide a common name in his description, he alluded to its vernacular name, the “Stripey,” commonly used by locals in New South Wales, Australia. Since the use of this name is pervasive throughout the region, we choose to retain it in part as the common name, proposing the usage of “East-Australian Stripey” instead to distinguish M. joyceae from M. strigatus.

[Crustacea • 2020] Richerius marqueti • A New Freshwater Crab of the Family Hymenosomatidae MacLeay, 1838 (Decapoda, Brachyura) and An Updated Review of the Hymenosomatid Fauna of New Caledonia


Richerius marqueti 
Guinot & Mazancourt, 2020


Abstract
A new genus and species, Richerius marqueti gen. et sp. nov., of a crab of the family Hymenosomatidae MacLeay, 1838 are described from the inland waters of New Caledonia based on several specimens collected in two streams at altitudes of 180 m and 500 m, respectively. Richerius marqueti gen. et sp. nov. was compared to the other freshwater species known in New Caledonia, Odiomaris pilosus (A.

Genus Richerius gen. nov.

Diagnosis: Carapace circular to oval, width only slightly exceeding length; dorsal carapace surface not strongly outlined by grooves; only gastrocardiac and thoracic grooves well defi ned, not reaching antero- and posterolateral margins; carapace rim continuous across behind rostrum. Rostrum broadly rounded, spade-shaped, slightly defl exed but not ending in narrow triangular tip extending between antennules. Proepistome represented by ventral expansion of rostrum (and not rostrum itself). Antennules obliquely folded along hollowed ventral parts of rostrum, entirely hidden dorsally. Antennae well separated from antennules, at least at their bases; urinary article at level of moderately developed epistome. Proepistome represented by ventral expansion of rostrum (and not rostrum itself). Lower orbital margin with one conspicuous knob, not visible dorsally. Mxp3 gaping at level of ischion/merus junction; merus and ischium broad, short, about subequal.

Etymology: The genus name is in honour of Bertrand Richer de Forges for his lifetime commitment to carcinology, especially of New Caledonia, for having always been an excellent and untiring researcher, and for his friendship. 


Richerius marqueti gen. et sp. nov.

Etymology: The species name is in honour of Gérard Marquet, who made extensive collections of freshwater crustaceans for more than 30 years in the Indo-Pacific islands and in particular in New Caledonia where he collected the new species here described, for his friendship and his constant enthusiasm in the field as well as in the laboratory.

[Crustacea • 2020] Lacunicambarus mobilensis & L. freudensteini • Two New Species of Burrowing Crayfish in the Genus Lacunicambarus (Decapoda: Cambaridae) from Alabama and Mississippi


 Lacunicambarus mobilensis 
Glon, Adams, Loughman, Myers, Taylor & Schuster. 2020


Abstract
While sampling for the Rusty Gravedigger, Lacunicambarus miltus, Taylor et al. (2011) found one or more potentially undescribed burrowing crayfish species in the genus Lacunicambarus inhabiting the area between the Pascagoula River and Mobile Bay in southern Alabama and Mississippi. Molecular analyses by Glon et al. (2018) confirmed that samples from this area were genetically distinct from other Lacunicambarus crayfishes. These findings prompted a dedicated sampling trip in January 2020. We used morphological and molecular analyses to investigate the specimens we collected and, based on our results, we describe two new crayfish species: the Lonesome Gravedigger, L. mobilensis sp. nov. and the Banded Mudbug, L. freudensteini sp. nov. Lacunicambarus mobilensis sp. nov. is sister to the Rusty Gravedigger, L. miltus, while L. freudensteini sp. nov. is sister to the Painted Devil Crayfish, L. ludovicianus. Both new species are currently known from a small number of sites in southern Alabama and Mississippi and may require conservation attention. In addition, we provide an updated key to Lacunicambarus crayfishes that includes these new species.

[Herpetology • 2020] Liolaemus qalaywa • An Endemic New Species of Andean Lizard of the Genus Liolaemus(Iguania: Liolaemidae) from southern Peru and Its Phylogenetic Position


Liolaemus qalaywa

 Amphibian & Reptile Conservation. 14(2)

Abstract
Integrative evidence of several external morphological characters and molecular phylogenetic analyses of mitochondrial DNA (12S, cyt-b) are used to place a new species of Andean lizard of the genus Liolaemus (Iguania: Liolaemidae) in the Liolaemus montanus group and as sister group of the clade formed by L. signifer. The new species is characterized by a unique combination of morphometric characteristics, scalation, and color pattern. The L. montanus group now contains seventeen species in southern Peru, distributed along the eastern and western slopes of the Andes. 

Keywords: Andes, Apurimac, Eulaemus, Puna, reptile, systematics, taxonomy



Liolaemus qalaywa sp. nov. 

Diagnosis. We assign L. qalaywa sp. nov. to the L. montanus group because it presents a blade-like process on the tibia, associated with the hypertrophy of the tibial muscle tibialis anterior (Abdala et al. 2019b; Etheridge 1995) and based on molecular phylogeny (Fig. 1). The species of the L. montanus group differ from those of the L. boulengeri group by the complete absence of patches of enlarged scales in the posterior part of the thigh (Abdala 2007). Compared to the species of the L. montanus group, L. qalaywa sp. nov. is a robust lizard differing by its larger size (max SVL = 96.06 mm) from L. andinus, L. audituvelatus, L. balagueri, L. cazianiae, L. chiribaya, L. duellmani, L. eleodori, L. erguetae, L. erroneus, L. etheridgei, L. evaristoi, L. fabiani, L. famatinae, L. fttkaui, L. foxi, L. gracielae
..... 

Etymology. The specifc epithet Qalaywa, refers to the Quechua word for the Liolaemus lizards from the high Peruvian Andes.

[Crustacea • 2020] New Records of Decapod Crustaceans (Malacostraca: Decapoda) from Kuwait


Polyonyx obesulus Miers, 1884

in Al-Kandari, Anker, Hussain, et al., 2020. 

Abstract
Seventeen species of shrimp-like decapod crustaceans (infraorders Caridea, Axiidea and Gebiidea) and two species of porcelain crabs (infraorder Anomura) are recorded for the first time from Kuwait, some of them also representing new records for the Arabian Gulf. The new records from Kuwait are: (1) Alpheus edamensis De Man, 1888; (2) Alpheus edwardsii (Audouin, 1826); (3) Alpheus macrodactylus Ortmann, 1890; (4) Alpheus maindroni Coutière, 1898; (5) Arete indicus Coutière, 1903; (6) Athanas parvus De Man, 1910; (7) Synalpheus gracilirostris De Man, 1910 [all Alpheidae]; (8) Latreutes mucronatus (Stimpson, 1860) [Hippolytidae]; (9) Thor paschalis (Heller, 1862) [Thoridae] (10) Periclimenella pettithouarsii (Audouin, 1826); (11) Anchistus custos (Forskål, 1775); (12) Urocaridella pulchella Yokes & Galil, 2006 [all Palaemonidae]; (13) Chlorocurtis jactans (Nobili, 1904) [Chlorotocellidae]; (14) Upogebia carinicauda (Stimpson, 1860); (15) Upogebia octoceras Nobili, 1904 [Upogebiidae]; (16) Balsscallichirus masoomi (Tirmizi, 1970), (17) Michaelcallianassa indica Sakai, 2002 [Callianassidae]; (18) Raphidopus persicus Ng, Safaie & Naser, 2012 and Polyonyx obesulus Miers, 1884 [Porcellanidae]. Most of these taxa have been previously recorded from other parts of the Arabian Gulf, mainly from the coasts of Iran and the United Arab Emirates, except for A. maindroni and U. pulchella, which are recorded from the Arabian Gulf for the first time. Most species are shown in colour photographs, some for the first time. In addition, the presence of Synalpheus quinquedens Tattersall, 1921 (Alpheidae), previously known from Kuwait based only on a questionable record in a popular field guide, is confirmed based on a single collected and preserved specimen.

[Herpetology • 2020] An Enigma No More: An Integrated Taxonomic Revision of Aenigmetopia Malloch (Diptera: Sarcophagidae: Miltogramminae) reveals Novel Phylogenetic Placement and Four New Species


Aenigmetopia sp.
Johnston, Wallman, Szpila & Pape, 2020.


Abstract
Aenigmetopia Malloch is the only endemic genus of miltogrammine flesh flies (Diptera : Sarcophagidae) in Australia and, until now it has been known from a single species, A. fergusoni Malloch. This study constitutes the first comprehensive taxonomic revision of Aenigmetopia. Four new species, Aenigmetopia amissa, sp. nov., A. corona, sp. nov., A. kryptos, sp. nov. and A. pagoni, sp. nov., are described through the integration of molecular and morphological data and characters for genus- and species-level diagnoses are given. Aenigmetopia is included in a molecular phylogenetic analysis for the first time and the genus emerges as the sister taxon to Metopia Meigen, in agreement with morphological evidence.

Keywords: DNA barcoding, flesh flies, phylogenetics.
