[Ornithology • 2017] Machaeropterus eckelberryi • A New Species of Manakin (Aves: Pipridae) from Peru with A Taxonomic Reassessment of the Striped Manakin (M. regulus) Complex


Machaeropterus eckelberryi
Lane, Kratter & O'Neill, 2017


Abstract

We describe a new taxon of manakin in the Machaeropterus regulus complex, from the foothills of southwestern Loreto and northern San Martín departments, Peru. This new form appears to be almost identical morphologically to the Tepui form M. regulus aureopectus but differs strongly from that and all other members of the M. regulus complex in voice. Therefore, we conclude that this population represents a new biological species that we here name Machaeropterus eckelberryi. Based on voice and some morphological characters, we concur with several previous authors (e.g., Whittaker & Oren 1999; Snow 2004; Ridgely & Tudor 2009) that nominate M. regulus (Eastern Striped Manakin), of the Atlantic Forest of Brazil, should be separated as a biological species from the polytypic Machaeropterus striolatus of western South America (Western Striped Manakin), including M. s. striolatus of Amazonia, M. r. obscurostriatus and M. r. zulianus of the Venezuelan Andes, M. r. antioquiae of the Colombian Andes, and M. r. aureopectus of the tepuis region.

Keywords: Aves, Vocal differentiation, San Martín, Cordillera Azul, suboscine, Neotropical, Aves

Though found in 1996, this manakin wasn't discovered to be a new species until researchers listened to its song years later.

Machaeropterus eckelberryi, species novum
Painted Manakin

Etymology. We are pleased to name this colorful manakin after one of the greatest American bird artists of the twentieth century, Donald R. Eckelberry. Not only did Eckelberry’s artwork increase the world’s awareness of the beauty of the birds of the Americas, particularly the Neotropics, but he also was a great force in the establishment of the Asa Wright Nature Center in Trinidad, and a wonderful mentor to young bird artists ( Angell 2001; Gilbert & Amadon 2001). Both JPO and DFL personally benefitted from Eckelberry’s generous advice and coaching in artistic matters. Don Eckelberry passed away on 14 January 2000, and we are sorry he did not live to see this paper published. We are, however, pleased to say that he was aware of our intention to grace this bird with his name and excited by the prospect. May his influence continue to inspire other nature artists in the future! The suggested English name refers to the colorful plumage of the male, and also serves as a nod to Eckelberry’s forte. If taxonomic committees that follow our recommendation of splitting up the M. regulus complex (see below) would prefer all sibling species retain “Striped” in the English name, a fine alternative name for M. eckelberryi would be “Peruvian Striped Manakin.”

[Ichthyology • 2017] Pseudochromis stellatus • A New Species of Dottyback (Teleostei: Pseudochromidae) from Indonesia


    Pseudochromis stellatus
 Gill, Allen & Erdmann, 2017


Abstract

The Pseudochromis reticulatus complex is diagnosed to include species of Pseudochromis with the combination of a pointed caudal fin (rounded with middle rays produced), a reticulated colour pattern on the upper part of the body, dorsal-fin rays modally III,26, anal-fin rays modally III,15, and pectoral-fin rays modally 18. Members of the complex include P. reticulatus Gill & Woodland, P. pictus Gill & Randall, P. tonozukai Gill & Allen, P. jace Allen, Gill & Erdmann and P. stellatus new species. The last-named is herein described from six specimens from Batanta and Batu Hitam in the Raja Ampat Islands, West Papua, Indonesia. It is distinguished from other members of the complex in live coloration, and in having higher mean numbers of scales in lateral series and of anterior lateral-line scales (36–38 and 29–32, respectively), and a deeper body as measured from the dorsal-fin origin to pelvic-fin origin (31.8–33.5 % SL).

 Pseudochromis stellatus sp. nov. 
Greenhead Dottyback 

Diagnosis. A species of Pseudochromis with the following combination of characters: dorsal-fin rays III,24– 26 (usually III,26); anal-fin rays III,15; pectoral-fin rays 18–19, usually 18; scales in lateral series 36–38; circumpeduncular scales 16; caudal fin pointed (rounded with middle rays extended to form slight to obvious point); and dorsal-fin origin to pelvic-fin origin 31.8–33.5 % SL.

Etymology. The specific epithet is from the Latin, meaning starry or starred, and alludes to the yellow spots on the upper part of the body. The name was selected by high school students as part of a science activity in the Macleay Museum.


Habitat and distribution. Pseudochromis stellatus is known from Batanta and Batu Hitam in the northern Raja Ampat Islands of West Papua Province, Indonesia, where it has been collected in 55–62 m and observed to at least 70 m depth. The new species is found on deep reef slopes with gentle incline but exposed to strong currents, and is generally found in association with small gorgonian sea fans or low-growing barrel sponges. It is most likely more widely distributed in the region, but confusion with similar yellow-spotted pseudochromids makes underwater identification difficult (see Comparisons). The species possibly ranges to Cebu, Philippines (see Remarks).

Abstract
Rhabdodontidae is a successful clade of ornithopod dinosaurs, characteristic of Late Cretaceous continental faunas in Europe. A new rhabdodontid from the late Campanian, of southern France, Matheronodon provincialis gen. et sp. nov., is characterized by the extreme enlargement of both its maxillary and dentary teeth, correlated to a drastic reduction in the number of maxillary teeth (4 per generation in MMS/VBN-02-102). The interalveolar septa on the maxilla are alternately present or resorbed ventrally so as to be able to lodge such enlarged teeth. The rhabdodontid dentition and masticatory apparatus were adapted for producing a strict and powerful shearing action, resembling a pair of scissors. With their relatively simple dentition, contrasting with the sophisticated dental batteries in contemporary hadrosaurids, Matheronodon and other rhabdodontids are tentatively interpreted as specialized consumers of tough plant parts rich in sclerenchyma fibers, such as Sabalites and Pandanites.

Matheronodon provincialis gen. et sp. nov.

Etymology. Matheron: in honor of Philippe Matheron, who was the first to describe dinosaur remains in Provence; odous (Greek): tooth; provincialis (Latin): from Provence (southern France).

Holotype. MMS/VBN-02-102, a right maxilla; housed in the collections of the Musée du Moulin seigneurial (MMS, Velaux, France).

Horizon and locality. ‘Begudian’ (local stage) sandstones, late Campanian, Late Cretaceous6,8. Velaux-La Bastide Neuve, Aix-en-Provence Basin, Bouches-du-Rhône, southern France.

Diagnosis. Rhabdodontid ornithopod characterized by the following autapomorphies: enlargement of both maxillary and dentary teeth (up to 5 cm in mesio-distal length); reduction of maxillary tooth families (4 per generation in MMS/VBN-02-102); interalveolar septa on the maxilla alternately present or resorbed ventrally, so that one functional tooth is lodged in two paired alveoli; shortened rostral process on the maxilla; broad dorsal shelf along the rostral third of the maxilla; more than 25 vertical and parallel ridges on the labial side of the maxillary teeth.

[Entomology • 2017] A Revision of the Myopsalta crucifera (Ashton) Species Group (Hemiptera: Cicadidae: Cicadettini) with 14 New Species from mainland Australia


Myopsalta albiventris Popple, 2107


Abstract

The genus Myopsalta Moulds is distributed throughout much of Australia. Previous studies have associated several undescribed species with the Myopsalta crucifera (Ashton) species complex. The present study informally divides the cicadas in the genus Myopsalta into two species groups. It provides a revision of the M. crucifera species group, which includes redescriptions of M. crucifera s. str. and M. mackinlayi (Distant). The identity of the latter species is further refined and attributed to material formerly presented under the name Myopsalta atrata (Goding & Froggatt). In addition to the redescriptions, 14 new species belonging to the M. crucifera species group are described, including M. albiventris n. sp., M. bassiana n. sp., M. chrysopedia n. sp., M. gordoni n. sp., M. leona n. sp., M. longicauda n. sp., M. majurae n. sp., M. melanobasis n. sp., M. parvula n. sp., M. platyptera n. sp., M. riverina n. sp., M. septa n. sp., M. umbra n. sp. and M. xerograsidia n. sp. A key to species in the genus Myopsalta is provided. Standard morphological descriptions and descriptions of calling songs unique to each species are included along with a discussion on different song types in the M. crucifera species group.

Abstract
Throughout the years, three infrageneric classifications were proposed for Tradescantia along with several informal groups and species complexes. The current infrageneric classification accepts 12 sections – with T. sect. Tradescantia being further divided into four series – and assimilates many concepts adopted by previous authors. Recent molecular-based phylogenetic studies indicate that the currently accepted sections might not represent monophyletic groups within Tradescantia. Based on newly gathered morphological data on the group, complemented with available micromorphological, cytological and phytochemical data, I present the first morphology-based evolutionary hypothesis for Tradescantia. Furthermore, I reduce subtribe Thyrsantheminae to a synonym of subtribe Tradescantiinae, and propose a new infrageneric classification for Tradescantia, based on the total evidence of the present morphological phylogeny, in accordance to the previously published molecular data.

[Botany • 2017] Ridleyandra merohmerea • A New Species (Gesneriaceae) from Kelantan, Peninsular Malaysia


Ridleyandra merohmerea  M.Y.Siti-Munirah & D.Zaharil

in Munirah & Dzulkafly, 2017

Abstract
Ridleyandra merohmerea, a new species of Gesneriaceae, is described and illustrated. It is endemic in Peninsular Malaysia and known from a few populations along the Tuang River in the lowland dipterocarp forest of the Ulu Galas Forest Reserve in Kelantan, Peninsular Malaysia. Its conservation status is assessed as Critically Endangered.

Ridleyandra merohmerea M.Y.Siti-Munirah & D.Zaharil, sp. nov.

Diagnosis: In its leaf shape and flower lobe colour, Ridleyandra merohmerea most resembles R. iminii Siti-Munirah but it differs in its leaves that are flat above and not wavy (glossy above and wavy), petiole 1–2 cm long (1–4 cm), oblanceolate and falcate lamina (lamina lanceolate oblong and not falcate), peduncle 8–13 cm long with green to dark purple (5–8 cm, pale green), pedicels 1–2 cm long (2.5–3 cm). In flower colour also is similar to R. iminii but differs in the sepal dark purple outer surface (sepals light green), corolla tube completely bright red outside (fully white outside).

Etymology: From the local dialect of Kelantanese people, ‘merohmerea’ means ‘merah terang’ in Malay and bright red in English. This name was chosen in the hope it will attract more Kelantanese to be more interested, concerned and aware of the importance of forest biodiversity in Kelantan especially since recently there are so many controversies and issues about disturbance to forests in Kelantan that in some cases might result in destruction of this new unique discovery. Hopefully, this name will attract more stakeholders to understand the importance of protecting and conserving the forest and this beautiful species and to realise that yet more new species are waiting to be discovered.

[PaleoIchthyology • 2017] Foreyia maxkuhni • Heterochronic Evolution Explains Novel Body Shape in A Triassic Coelacanth from Switzerland


Foreyia maxkuhni 
Cavin, Mennecart, Obrist, Costeur & Furrer, 2017


Abstract

A bizarre latimeriid coelacanth fish from the Middle Triassic of Switzerland shows skeletal features deviating from the uniform anatomy of coelacanths. The new form is closely related to a modern-looking coelacanth found in the same locality and differences between both are attributed to heterochronic evolution. Most of the modified osteological structures in the new coelacanth have their developmental origin in the skull/trunk interface region in the embryo. Change in the expression of developmental patterning genes, specifically the Pax1/9 genes, may explain a rapid evolution at the origin of the new coelacanth. This species broadens the morphological disparity range within the lineage of these ‘living fossils’ and exemplifies a case of rapid heterochronic evolution likely trigged by minor changes in gene expression.

[Ichthyology • 2017] Austrolebias camaquensis • A New Annual Fish of the Genus Austrolebias (Cyprinodontiformes: Rivulidae) from Rio Camaquã basin, Laguna dos Patos system, Brazilian Pampa


Austrolebias camaquensis 
 Volcan, Gonçalves & Lanés, 2017


Abstract

A new species of Austrolebias is described from the middle course of the Rio Camaquã, Laguna dos Patos system, Rio Grande do Sul, Brazil. The new species belongs to the Austrolebias alexandri species group, which is distinguished from the remaining congeners by the presence of a dark gray pectoral fin with bright blue iridescence in males. The new species is distinguished from all remaining species of the A. alexandri species group by the following combination of characters: presence of well-defined bright blue bars on the flank in males, shorter caudal fin length in males and females, contact organs in the first three rays of the pectoral fin in males, one to two post-optic neuromasts (rarely three), basihyal width of 50% of the length, and basihyal cartilage about 50–60% of the basihyal length. The recognition of this new species belonging to the A. alexandri group endemic of the middle course of Rio Camaquã and the recent discovery of Austrolebias bagual in the same general region reinforces the claim of the middle Rio Camaquã basin as an area of endemism for annual fishes and as such, a priority area for conservation in southern Brazil.

Etymology: We name this species after the local Cơ Tu ethnic minority, who use various parts of the plant in their traditional medicine for its anti-inflammatory properties.

Vernacular name and uses: The vernacular name of this species, Pơr’vih in the Cơ Tu language, conveys an idea of keeping the living environment of people in the village peaceful and protected against bad spirits. The main rhizome is stewed with chicken and eaten by women after birth, giving them strength to work soon afterwards. It also reduces menstrual cramp in women. Raw root tubers are mixed with honey to treat coughs in children. Young leaves are mixed with rock salt to treat toothache and gingivitis. Fresh leaves are also used for wrapping fresh fish to preserve it from spoilage. The local people also believe that the plant possesses magic qualities preventing people from getting lost in the forest.

[Ichthyology • 2017] Channa shingon • A New Dwarf Snakehead (Perciformes: Channidae) from western Yunnan


Channa shingon
 Endruweit, 2017 

 Vertebrate Zoology. 67(2) 

Abstract

 Channa shingon, new species, is described from small mountainous rivulets associated with the Irrawaddy drainage in western Yunnan Province, China. Its maximum SL of about 100 mm makes it the smallest pelvic-fin bearing dwarf snakehead. Further specific characters are lateral head length 27–30 % SL; interorbital width 33 –35 % HL; 25–27 anal-fin rays; 44–45 lateral-line scales; 4 –5 scale rows between dorsal-fin origin and lateral line; 8 –9 scale rows between lateral line and anal-fin origin; 1 mandibular scale; 43–44 vertebrae; inferomesial process of parasphenoid very shallow and straight; dorsal profile conspicuously bulging in front of dorsal fin; juveniles without ocellus-like mark on posterior part of dorsal fin; and a pectoral-fin pattern of 3 – 4 broad gray to black bands alternating with cream to white interspaces, bands increasingly wide towards distal edge of the fin, interspaces equally wide as bands or narrower.

Channa shingon, new species

Diagnosis. Channa shingon is distinguished from other members of the C. gachua-complex (Britz, 2008) by having a lateral head length 27–30 % SL; interorbital width 33 – 35 % HL; 25–27 [26] anal-fin rays; 44– 45 [45] lateral-line scales; 4 –5 [4] transverse scales to dorsal-fin origin and 8–9 [8] to anal-fin origin; 1 mandibular scale, 43 –44 [44] vertebrae; inferomesial process of parasphenoid very shallow and straight; dorsal profile conspicuously bulging in front of dorsal fin; pelvic fin present; juveniles without ocellus-like mark on posterior part of dorsal fin; a pectoral-fin pattern of 3–4 broad gray to black bands alternating with cream to white interspaces, width of bands increasing towards distal edge of the fin, interspaces equally wide as bands or narrower; and a maximum standard length of about 100 mm.

Distribution. Known from the Irrawaddy and Salween drainages in Dehong and Lincang prefectures, Yunnan, China; expected to occur in the same drainages in Myanmar.

 Ecology. Channa shingon prefers weedy, stagnant water sections of small mountainous rivulets. These rivulets are often redirected to irrigate rice paddies. At the type locality, the ankle-deep water was clear, with a pH of 5.9, a conductivity of 20 µS/cm, and a temperature of 12 ºC in the afternoon. The lower reaches of these rivulets, shortly before the influx into a larger stream are usually also inhabited by Misgurnus anguillicaudatus and juveniles of C. harcourtbutleri. Another habitat of C. shingon, the Mengnaihe River upstream of Xima at an elevation of 1730 m, had a water temperature of just 8 ºC in the morning (pH 6.7; 20 µS/cm); some backwaters had a thin layer of ice after a chilly night. Vast areas of C. shingon’s habitats are ephemeral and desiccate during droughts.

Etymology. The specific epithet is derived from a character in Burmese spiritualism. Shingon, also referred to as Lady Humpback, is one of the 37 officially recognized spirits (nats) in Myanmar; an allusion to the species’ humpbacked appearance; a noun in apposition.
