Sturnira perla, the new species described herein, is diagnosed as an independent phylogenetic lineage in hypotheses derived from mitochondrial sequences, and shows acceptable distances in terms of genetic divergence. This description also relies on the statistical interpretation of morphological dissimilarity and overlap, and avoids qualitative judgments of character variation. Overall, this new species is characterized by a spherical skull, noticeable round and robust, with pronouncedly curved zygomatic arches. Statistical evidence that supports the discrimination of other species in Sturnira, based on external characters such as pelage coloration or number of hairs, is absent in the literature. In this sense, the geometry of the skull for this newly described species shows the sharpest morphological boundaries, relative to other closely related and sympatric taxa. This new species is likely endemic to the Choco forest, specially at its southern limits. This is an area known for its high levels of endemism. The magnitude of environmental disruption in the Choco and the potential rarity of this new species may be negatively affecting its probability of survival.

A New Species

We describe a new species of drongo in the Square-tailed Drongo (Dicrurus ludwigii) complex using a combination of biometric and genetic data. The new species differs from previously described taxa in the Square-tailed Drongo complex by possessing a significantly heavier bill and via substantial genetic divergence (6.7%) from its sister-species D. sharpei. The new species is distributed across the gallery forests of coastal Guinea, extending to the Niger and Benue Rivers of Nigeria. We suspect that this taxon was overlooked by previous avian systematists because they either lacked comparative material from western Africa or because the key diagnostic morphological character (bill characteristics) was not measured. We provide an updated taxonomy of the Square-tailed Drongo species complex.

A new species of the Gekko japonicus group is described from Khammouane Province, central Laos, based on morphological characters and molecular data. Morphologically, Gekko nadenensis sp. nov. is differentiated from the remaining congeners by a combination of the following characters: size moderate (SVL 61.0–77.1 mm); nares bordered with rostral; internasals absent; postmentals enlarged; interorbital scales between anterior corners of the eyes 28–30; dorsal tubercles absent; ventral scales between mental and cloacal slit 175–185; midbody scale rows 123–140; ventral scale rows 38–40; subdigital lamellae on first toes 13–15, on fourth toes 14–16; finger and toe webbing present at base; tubercles on dorsal surface of fore and hind limbs absent; precloacal pores six (3+3 or 5+1) in a discontinuous row in males, absent in the female; postcloacal tubercles 1 or 2; tubercles absent on dorsal surface of tail base; subcaudals distinctly enlarged; dorsal surface of body with greyish brown blotches. Molecular analyses demonstrated the new species is closely related to G. bonkowskii and G. thakhekensis, but separated from them by approximately 7% in genetic divergence as shown by a fragment of the mitochondrial ND2 gene.

A New Species

A new species of African reed frog (genus Hyperolius Rapp, 1842) is described from the Coastal Forests of the Eastern Africa Biodiversity Hotspot in northeastern Mozambique. It is currently only known from less than ten localities associated with the Mozambican coastal pans system, but may also occur in the southeastern corner of Tanzania. Phylogenetic reconstructions using the mitochondrial 16S marker revealed that it is the sister taxon of Hyperolius mitchelli (>5.6% 16S mtDNA sequence divergence) and forms part of a larger H. mitchelli complex with H. mitchelli and H. rubrovermiculatus. The new species is distinguished from other closely related Hyperolius species by genetic divergence, morphology, vocalisation, and dorsal colouration.

A new species of the processid shrimp genus Nikoides Paul’son, 1875, N. subdistalis, is described and illustrated on the basis of five specimens collected from Kushimoto, Wakayama Prefecture, Japan, at depths of 7–12 m. The new species appears most similar to N. maldivensis Borradaile, 1915 among the 10 known congeners, but is notable in the unique dentition of the rostrum and the characteristic shape of the antennular stylocerite. A partial segment of the mitochondrial 16S rRNA gene was sequenced from one of the paratypes of the new species, and genetic divergence among four congeneric taxa, of which three was downloaded from the GenBank database, is shown. An identification key to 11 species of Nikoides, including the new species, is given.

A New Species

A new species of African reed frog (genus Hyperolius Rapp, 1842) is described from a high altitude, forested gorge in theSerra da Chela mountain range near the village of Humpata, Lubango area, Huila Province, south-western Angola. It iscurrently only known from its type locality. Phylogenetic reconstruction using the mitochondrial 16S marker reveals thatit is the sister taxon of the poorly known Hyperolius cinereus (>4% sequence divergence) also described from Angola, andforms part of a larger clade comprising H. platyceps. The new species is distinguished from other closely related Hyperolius species by genetic divergence, vocalisation, an unusual torrent stream habitat, and colouration.

A New Species

The aim of this study was to describe the new rhodolith-forming coralline alga species, Sporolithon yoneshigueae sp. nov., based on both morpho-anatomical and molecular data. Specimens were collected in rhodolith beds between 28 and 66 m depths in northeastern and southeastern Brazil. The new species can be distinguished from all other species of the genus Sporolithon by its wide tetrasporangial compartment pore diameter (35–43 µm) and the correspondingly large number (19–24) of rosette cells surrounding the tetrasporangial compartment pore. Phylogenies inferred from psbA and SSU markers support it as a new species within Sporolithon with interspecific genetic divergence varying from 8.86–10.94 %, and 3.67–4.63%, respectively. Observations from recent gathering and from herbarium collections show that specimens previously designated as Sporolithon mediterraneum in Brazil correspond to Sporolithon yoneshigueae.

A New Species

We describe a new species of Auriculostoma Scholz, Aguirre-Macedo & Choudhury, 2004 based on several sources of information including morphology (light and scanning electron microscopy [SEM]), sequences of two nuclear genes, host association, and geographical distribution. Morphologically, the new species most closely resembles Auriculostoma astyanace Scholz, Aguirre-Macedo & Choudhury, 2004, but differs by having deeply lobated testes and cirrus-sac extending posteriorly to seminal receptacle level. Auriculostoma lobata n. sp. can be readily distinguished from all the other congeners by the combination of the following characters: testes located in tandem, testes deeply lobated, and larger body size. A phylogenetic analysis using 28S rDNA sequences along with those available for other allocreadiid trematodes, revealed that the new species is a sister taxon of A. astyanace, a species described from the banded astyanax, Astyanax fasciatus (Cuvier) in Nicaragua. Auriculostoma totonacapanensis Razo-Mendivil, Mendoza-Garfias, Pérez-Ponce de León & Rubio-Godoy, 2014 from the Mexican tetra, Astyanax mexicanus (De Filippi) in Mexico is the sister taxon of A. astyanace plus the new species. Genetic divergence levels for the 28S rDNA and ITS2 were estimated among the Middle-American species of Auriculostoma infecting characiforms. The validity of the new species is then established by reliable morphological differences, its host association to bryconids (Brycon guatemalensis Regan), restricted geographical distribution (Usumacinta and Lacantun River basins), and genetic divergence levels, albeit relatively low. A morphometric comparison between the new species and the other seven congeneric species was undertaken and, in addition, a taxonomic key to identify the species contained in the genus Auriculostoma, widely distributed across the Americas, is provided.

A New Species

A new species of the butterflyfish genus Prognathodes (Chaetodontidae) is described from two specimens collected at a depth of 116 m off Ngemelis Island, Palau. Prognathodesgeminussp. n. is similar to P.basabei Pyle & Kosaki, 2016 from the Hawaiian archipelago, and P.guezei (Maugé & Bauchot, 1976) from the western Indian Ocean, but differs from these species in the number of soft dorsal-fin rays, size of head, body width, and body depth. There are also subtle differences in life color, and substantial differences in the mtDNA cytochrome oxidase I sequence (d ≈ 0.08). Although genetic comparisons with P.guezei are unavailable, it is expected that the genetic divergence between P.guezei and P.geminus will be even greater than that between P.geminus and P.basabei. It is named for the strikingly similar color pattern it shares with P.basabei.
