While the island of Borneo is considered a global biodiversity hotspot, the species richness in many groups remains unknown and appears underestimated. During herpetological surveys carried out in the interior of Sarawak, East Malaysia, several individuals of a small species of the genus Ansonia Stoliczka 1870 were collected on the Usun Apau plateau and in the Gunung Hose mountain range (Ansonia sp. Usun Apau). An integrative taxonomic approach comprising phylogenetic (2.4 kb mitochondrial rDNA fragment, Bayesian Inference and Maximum Likelihood, >5.1 % to its closest relative) and morphometric analyses (25 measurements, multivariate ratio analysis and linear discriminant analysis), as well as morphological comparisons support the status of this operational taxonomic unit as a separate taxon at species level. The obtained phylogenetic hypothesis corroborates the two major clades within Ansonia found in previous studies. Within Clade One Ansonia sp. Usun Apau and the enigmatic Ansonia torrentis are part of a monophyletic group of the Bornean species Ansonia hanitschi, Ansonia minuta, Ansonia platysoma, Ansonia spinulifer, Ansonia vidua, and two additional undescribed taxa. This subclade must be considered as the result of an on-island radiation in the complex evolution of Ansonia. The new species is formally described including the identification of diagnostic morphometric traits. Ansonia sp. Usun Apau is endemic to two isolated mountain ridges in central Sarawak and must be considered as a new element of the unique diversity of the Bornean amphibian fauna that is potentially threatened by habitat loss at least in parts of its range.

Fig. 5: Coloration in life of a female Ansonia teneritas sp. nov. from the type locality on the Usun Apau plateau  

Diagnosis: The new species is assigned to the genus Ansonia on the basis of a robustly supported phylogenetic hypothesis (Fig. 3) and the presence of the following morphological characters: body slender, subarticular tubercles indistinct, limbs long and slender, webbing membranous, parotid glands absent, and tympanum visible (Inger 1960, 1966).

Ansonia teneritas sp. nov. can be distinguished from all congeners by the following combination of characters: (1) SVL in males <22 mm, in females <25 mm; (2) snout clearly projecting in profile; (3) head depressed; (4) longitudinal interorbital ridges absent; (5) first finger short, not reaching base of tip of second finger when adpressed; (6) no sharp tarsal ridge; (7) skin flaps on posterior thigh near vent absent; (8) warts on temporal regions not enlarged; (9) coloration olive-green with a contrasting dark brown pattern on head and dorsum; (10) whitish pattern below the eye on upper lip; (11) white warts behind jaw joint, on shoulders and flanks; (12) iris bright red-orange with an irregular network of black reticulations.

Etymology: The species name teneritas, Latin for ‘tenderness’, refers to the gracile body shape and small body size of this species in comparison to congeners. We suggest the English name ‘Gracile Slender Toad’.

Ecological notes: The type locality of Ansonia teneritas sp. nov. is a small tributary of the upper reaches of the Sungei Julan, just above the spectacular falls of the Sungei Julan Valley on the northern side of the Usun Apau plateau (Fig. 8). The Usun Apau plateau is part of the Central Bornean plateau and forms the watershed between the Rejang and Baram river basins in central Sarawak (Hutchison 2005; Rousseau 1977). The Sungei Julan is a tributary of the Baram drainage system. It consist of several tablelands and smaller plateaus with an elevation of approximately 760–1000 m with sharply cut edges, precipitous cliffs, and deep marginal embayments (Hutchison 2005). The Usun Apau highlands were formed by extensive volcanic activity during the Upper Miocene to Quaternary, and the few mountains that stand over 300 m above the tablelands are relicts of former volcanoes (Hutchison 2005). As a result of their volcanic formation history the high tablelands of the central area are built up of dacite tuff and agglomerate, while the southern mountains are covered by basalt lava (Hutchison 2005; Campbell 1956). The area covers about 700 sq. km of forest and has been protected as the Usun Apau National Park since 2005.

Adult frogs of the following species were detected in the immediate vicinity of the stream and the surrounding forest: Ansonia longidigita Inger, 1960; Hylarana picturata (Boulenger 1920); Leptobrachella mjobergi Smith, 1925; Limnonectes cf. kuhlii (Tschudi, 1838); Limnonectes ibanorum (Inger 1964); Meristogenys sp., Metaphrynella sundana (Peters, 1867); Microhyla petrigena Inger and Frogner 1979; Occidozyga laevis (Günther 1858); Philautus hosii (Boulenger 1895); Philautus macroscelis (Boulenger 1896); Philautus cf. mjobergi Smith, 1925; Philautus tectus Dring, 1987; and Staurois parvus Inger and Haile, 1959.

 DOI:  10.1086/687566 

We report a new chameleon-like Anolis species from Hispaniola that is ecomorphologically similar to congeners found only on Cuba. Lizards from both clades possess short limbs and a short tail and utilize relatively narrow perches, leading us to recognize a novel example of ecomorphological matching among islands in the well-known Greater Antillean anole radiation. This discovery supports the hypothesis that the assembly of island faunas can be substantially deterministic and highlights the continued potential for basic discovery to reveal new insights in well-studied groups. Restricted to a threatened band of mid-elevation transitional forest near the border of the Dominican Republic and Haiti, this new species appears to be highly endangered.

[Botany • 2016] Bidoupia phongii • A New Orchid Genus and Species (Orchidaceae, Orchidoideae, Goodyerinae) from southern Vietnam

Bidoupia phongii  Aver., Ormerod et Duy.

DOI:  10.11646/phytotaxa.266.4.6

Species of subtribe Goodyerinae (Orchidaceae, Orchidoideae) in the flora of Vietnam have been the subject of a series of taxonomic treatments (Seidenfaden 1992, Averyanov 1994, 2008, Averyanov & Averyanova 2003, Nguyen, Averyanov & Duong 2005). Nonetheless, the inventory of this group remains incomplete due to their sporadic distribution, rarity in nature, and deficiency of available herbarium and living collections. Additionally, almost all Goodyera-related species rarely flower either in nature or cultivation, which makes available observations scarce. As a result, new data on species and records for the flora of Vietnam are appearing continuously (Ponert et al. 2014, Averyanov et al. 2016) in addition to the already completed accounts. One more curious novelty from Goodyerinae discovered recently in southern Vietnam is described and illustrated below.

The unusual plant described here was discovered in 2010 during botanical investigations conducted by international team of botanists under leadership of Nong Van Duy, Vice Director of the Tay Nguyen Institute for Scientific Research, Vietnam Academy of Science and Technology in the northeastern part of Tay Nguyen Plateau (Central Highlands) of southern Vietnam. Phytogeographically, the largest part of this area coincides with the South Annamese floristic province of the Indochinese floristic region that is particularly rich in plant diversity and endemism (Averyanov et al. 2003). The new species is probably a local endemic of the Bidoup Range, the chain of high mountains along the border between Lam Dong and Khanh Hoa provinces in southern Vietnam. In this region, the species occurs with such typical local endemics as Arachnis annamensis (Rolfe 1905: 391) Smith (1912: 73), Vanda christensonia (Haager 1993: 39) L.M.Gardiner (2012: 49), Bulbophyllum clipeibulbum Vermeulen (2001: 51), Paphiopedilum delenatii Guillaumin (1924: 554) and Schoenorchis hangianae Averyanov & Duy (2015: 117). This species is rare and known thus far from just a single collection. It is noteworthy that the locality for this plant in primary forest is presently being seriously disturbed by road construction, logging and anthropogenic transformation. For these reasons, it is tentatively assessed as a highly endangered species due to loss of its habitat. It should be especially emphasized that this unique taxon could become extinct in the near future, and its conservation and protection needs further field investigation.

[Ichthyology • 2016] Gobius salamansa • A New Species of Goby (Gobiidae) from the Cape Verde Islands supported by A Unique Cephalic Lateral Line System and DNA Barcoding

Gobius salamansa  
 Iglésias, Frotté & Sellos, 2016


Gobius salamansa sp. nov., a new species of tropical eastern Atlantic goby (Teleostei: Gobiidae: Gobiinae) is described from the island of São Vicente in the Republic of Cabo Verde. With adults measuring less than 35 mm TL (total length) it is the smallest species among Gobius. It is easily distinguishable from its Atlantico-Mediterranean congeners thanks to a unique character: an additional posterior ocular head pore, newly named α’, part of the anterior oculoscapular canal and connected to pore α by a suborbital branch. The new species also possesses a rare character among gobiids: a continuous oculoscapular canal, undivided into anterior and posterior parts. The species is distinguishable from its relatives thanks to its distinctive multi-colored (white, red, black, yellow and brown) eyespot, located on the first dorsal fin; by a low number of soft rays on the second dorsal fin (11) and anal fin (9); by row r not divided into two sections; by a divided row d. The two type of specimens were collected at 0.2–0.6 m depth, at the entrance of cracks in compact volcanic boulders forming a rocky islet submerged at high tide. DNA barcoding based on COI of the species compared with sympatric gobiids and species of Atlantico-Mediterranean Gobius reveals a high nucleotide sequence divergence [Kimura’s (1980) two parameter distances of 16.5 %)], with Gobius ateriformis identified as its closest species. A dichotomous key for Gobius–Mauligobius from tropical eastern Atlantic is provided. It is the eleventh gobiid species, and the fourth endemic species, to be described in Cape Verde.

Keywords: Gobiinae, New species, Eastern Atlantic, Republic of Cabo Verde, Head pore

Diagnosis. The new species is characterized by a unique character among the gobiids: (1) an additional posterior ocular head pore, newly named α’, and connected to pore α by a suborbital branch of the anterior oculoscapular canal; (2) a distinctive multi-colored (white, red, black, yellow and brown) eyespot, located on the first dorsal fin. The new species is also characterised by the combination of the following characters: (1) the possession of pores on the oculoscapular (σ, λ, κ, ω, α, β, ρ, ρ1, ρ2), and preopercular (γ, δ, ε) head canals; (2) a canal section between pore ρ and ρ1 connecting the anterior and the posterior oculoscapular canals; (3) a divided row d; (4) row r not being split into two sections; (5) row x1 ending anteriorly behind pore β; (6) six transverse infraorbital rows of sensory papillae (1–6), with five anterior to the hyomandibular row b but only one above, and with the inferior sections of rows five and six well developed below row b; (7) row g ending behind row o; (8) six well developed upper free pectoral rays; (9) anterior nostril with a digitate process; (10) predorsal area and nape scaled; (11) 11 soft rays on the second dorsal, 9 soft rays on the anal fin; (12) 36–37 scales on LL; (13) a scaleless cheek and opercle. The new species also differs from close GobiusMauligobius relatives by the combination of the following characters: a white breast; a thin caudal peduncle, with a depth 45–50 % of caudal peduncle length; a long pectoral fin, 29–30 % of standard length; a long pelvic fin, 23–25 % of standard length; large eyes, 38–39 % of head length; a short snout, 25–26 % of head length, short interorbital width, 7.5–8.5 % of eye diameter.

Distribution and habitat. — Known presently only in the Bay of Salamansa at São Vicente, Cape Verde Islands, 16.909545° N, -24.938012° W. The specimens were observed in a subtidal area at the entrance of cracks in compact volcanic boulders forming a rocky islet submerged at high tide about one hundred meters from the beach. The basaltic rocks were covered with short seaweeds and coralline algae. The habitat was largely colonized by the subtidal blenniids Ophioblennius atlanticus (Valenciennes in Cuvier and Valenciennes 1836) and Scartella caboverdiana Bath 1990. The rocky islet was surrounded by sand, rock and coral bottom, 1–3 m depth, where individuals of G. ateriformis were common under rocks. The sea temperature was 24 C at the point of collection.

Etymology.— The epithet salamansa refers to the village of Salamansa, on the north of the island of São Vicente, Republic of Cabo Verde , which marks the location where the only two known specimens were collected. The specific name salamansa is proposed as a noun in apposition.

[PaleoIchthyology • 2015] Pseudomegachasma gen. nov. • A New Clade of Putative Plankton-Feeding Sharks from the Upper Cretaceous of Russia and the United States

FIGURE 7. Stratigraphic distributions of elasmobranch families that contain planktivorous forms and highlighting Johnlongia and Pseudomegachasma, gen. nov., as well as Megachasma applegatei and M. pelagios to show parallel evolution and convergence of ‘megachasmid tooth pattern’ from ‘odontaspidid tooth pattern’ in each clade (*, excludes other odontaspidid taxa outside of this particular clade, i.e., Johnlonginae, subfam. nov.; stratigraphic data based on Friedman et al., 2010:fig. 3; Cappetta, 2012; Shimada et al., 2014). Sources of illustrated teeth (left, labial view; right, profile view; not to scale): Johnlongia (SSU 155/93 in this study; cf. Fig. 2 A, C); Pseudomegachasma , gen. nov.

Eorhincodon casei from Russia and Megachasma comanchensis from the United States are two Cretaceous taxa initially described as putative planktivorous elasmobranchs, but the type specimens of these two taxa were subsequently reinterpreted to represent taphonomically abraded teeth of an odontaspidid, Johnlongia Siverson (Lamniformes: Odontaspididae). Here, we redescribe the type materials of ‘E. casei’ and ‘M. comanchensis’ and describe additional specimens of these species from other Late Cretaceous localities in Russia and the United States. These specimens demonstrate that (1) the two fossil taxa are valid species; (2) they warrant the establishment of a new genus of presumed planktivorous sharks, Pseudomegachasma, gen. nov., to accommodate the two species; and (3) the new genus is sister to Johnlongia and together constitute a new subfamily Johnlonginae, subfam. nov., tentatively placed in the family Odontaspididae sensu stricto. This taxonomic placement indicates that the putative planktivorous clade was derived from a presumed piscivorous form (Johnlongia), with an implication that Pseudomegachasma, gen. nov., evolved a plankton-eating habit independent of the four known planktivorous elasmobranch clades (Rhincodontidae, Megachasmidae, Cetorhinidae, and Mobulidae). It also indicates that planktivorous diets evolved independently at least three times in the order Lamniformes (i.e., Megachasmidae, Cetorhinidae, and Odontaspididae), and more significantly, Pseudomegachasma, gen. nov., would represent the oldest known plankton-feeding elasmobranch in the fossil record. The present fossil record suggests that Pseudomegachasma, gen. nov., evolved in a relatively shallow-water environment in Russia in the early Cenomanian or earlier and subsequently migrated to the North American Western Interior Seaway by the mid-Cenomanian.

[Botany • 2016] Cryptocoryne aura • A New Species (Araceae) from West Kalimantan, Indonesia

Cryptocoryne aura 
  Wongso & Ipor 

A new species, Cryptocoryne aura Wongso & Ipor, from West Kalimantan, Indonesia, is described and illustrated. It differs from other Cryptocoryne species primarily by having a transparent, ciliate membrane along the leaf margin and a short spathe with a yellow, forward-twisted limb. It has a chromosome number of 2n = 26, which has not hitherto been recorded within the genus. The morphology of the germinating seed is unique within the genus, the embryo emerging c. ⅓ from the distal end of the seed with 3(or 4) plumulary processes (prophylls).

 Cryptocoryne aura Wongso & Ipor, sp. nov.

Holotype: Indonesia, Kalimantan Barat, West Kalimantan, Kabupaten Sekadau, Kecematan Nanga Taman, 26 Feb 2015, S. Wongso & I. B. Ipor SW1508 (BO; isotypes: C, L, M, SAR, Herbarium Universiti Malaysia Sarawak).

Diagnosis — Cryptocoryne aura differs from all other Cryptocoryne species by having the leaf blade margin with a distinct, whitish, slightly transparent, undulate membrane with whitish, short, ciliate trichomes. The germinating seed is unique within the genus in that the embryo emerges c. ⅓ from the distal end of the seed and bears 3(or 4) plumulary processes (prophylls). Its chromosome number of 2n = 26 has hitherto not been recorded for Cryptocoryne

Photographed on 26 February 2015 by S. Wongso.

Etymology — The epithet alludes to the well-developed, slightly transparent, whitish membrane surrounding the leaf margin, which is likened to an aura.

Remarks — Cryptocoryne aura has a growth stature resembling that of Celliptica Hook. f. (Peninsular Malaysia) and Cbogneri Rataj (Sri Lanka) in having all parts of the plant of small size and a rosette of many leaves, indicating that the plants are situated in shallow water with the leaf blades just below the water surface. This common rosette phenomenon in these species is no doubt an adaptation to similar habitat niches and does not necessarily reflect a close phylogenetic relationship.

The morphology of the germinating embryo is unique for the genus, with the seeds having a rather thin and pointed distal end, with the embryo breaking through the testa c. ⅓ from this end with 3(or 4) plumulary processes (prophylls); the primary root emerges from the distal end of the seed, while secondary roots emerge along with the plumulary processes.

[Crustacea • 2016] Fallicambarus schusteri • A New Burrowing Crayfish of the Genus Fallicambarus Hobbs, 1969 (Decapoda: Cambaridae) from the Red River Drainage of the southcentral United States

Fallicambarus schusteri 
Taylor & Robison, 2016 


A new primary burrowing crayfish, Fallicambarus schusteri, is described from the Red River drainage of extreme southeastern Oklahoma and southwestern Arkansas and is placed in the subgenus Fallicambarus. The species occurs in roadside ditches that seasonally flood and have silt and silt-loam dominated soils. Falllicambarus schusteri differs from all other members of the genus Fallicambarus in possessing a thin gradually tapering central projection and a wide triangular cephalic process on the first pleopod of form I males, a sufflamen on the cheliped, and an antennal scale that is widest at its midpoint.
