Yet another small brown frog from high altitude on the Marojejy Massif, northeastern Madagascar (Anura: Mantellidae)

Madagascar hosts a high diversity of small brown frogs. In this paper, we add another one by describing Gephyromantis (Duboimantis) tohatra sp. nov. The new species is a small brown mantellid frog discovered on a recent expedition to Marojejy National Park in northeastern Madagascar. It is characterised, among other things, by its small size (snout-vent length ~33 mm), an orange to yellowish belly, two dorsolateral ridges, and a distinctive call composed of 7–10 pulsed notes. The new species occurs sympatrically with other members of the subgenus Duboimantis at high altitude (~1700 m above sea level), including its sister species G. schilfi from which it radically differs by advertisement call and by a substantial genetic divergence of 4.3% uncorrected pairwise distance in the mitochondrial 16S rRNA gene. It thus joins the diverse assemblage of Gephyromantis species known from high altitudes on the mountain massifs of northern Madagascar.

A new species of Hyperolius is described from Nyungwe National Park in southern Rwanda. The new species differs fromits congeners by a unique combination of morphological characters, including a light green dorsum and a transparentventral skin resembling glass frogs of the Neotropical family Centrolenidae, blue-coloured bones, reduced toe webbing,relatively wide head, acuminate snout, small to medium size (SUL of adult males 18.8–23.2 mm), and the presence ofnuptial pads. The advertisement call differs from all calls of other species of the genus that have been analyzed.Comparison of the mitochondrial 16S rRNA gene showed a relatively close relationship to H. castaneus, H.cystocandicans, H. discodactylus, H. frontalis, and H. lateralis. The 16S sequence of the new species differs by at least 4.5% in the uncorrected p-distance from all available sequences of other species of the genus.Ubwoko bushya bwa Hyperolius buboneka muri parike nasiynali ya Nyungwe mu majyepfo yu Rwanda.

A New Species

Within Sundaland, the species diversity of the genus Megophrys is richest in Borneo, with some species restricted to the northern highlands of the island. On the basis of molecular, morphological and acoustic evidence, we describe a new species of large-sized Megophrys, once confused with M. nasuta. The new species Megophrys kalimantanensis sp. nov. can be differentiated from all its congeners by large genetic distance more than 6.11% in the mitochondrial 16S rRNA gene, much shorter rostral and orbital appendages, and unique advertisement call. This new species has been recorded from medium to high altitudes of mountain forest in southern and northernmost Borneo.

A New Species

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

Cnemaspis flaviventralis, a new species of day gecko, is described from the forests of Amboli, Sindhudurg District, Maharashtra State, northern Western Ghats, India. The new species was previously confused with the sympatric species Cnemaspis girii, C. indraneildasii, C. kolhapurensis and C. goaensis. It is distinguished from C. giri by having spine-like tubercles on flanks, granular dorsal scales intermixed with large, depressed, slightly keeled scales (vs. lack of spine-like tubercles on flanks, granular dorsal scales, intermixed with large smooth scales); from C. indraneildasii by having dorsal scales heterogeneous (vs. homogenous), lacking a series of enlarged median sub-caudal scales, and 28–29 (vs. 20) ventral scales across mid-body; from C. kolhapurensis by having heterogeneous (vs. homogenous) dorsal scalation, lacking spine-like tubercles on flanks and lacking pre-cloacal pores (vs. 24–28 pre-cloacal-femoral pores); and from C. goaensis by lacking pre-cloacal pores and lacking a series of enlarged median sub-caudal scales. We further provide partial mitochondrial 16S rRNA gene sequences for the new species and for the sympatric species C. girii, C. kolhapurensis and C. goaensis, and show that the new species is genetically distinct.

Iucn Red List Criteria

We describe a new species of arboreal narrow-mouthed frog, genus Platypelis, from Ambodivoangy near Maroantsetra in northeastern Madagascar. The new species, Platypelisandosp. nov., is characterised by small body size (under 19 mm), a generally rather slender body, yellowish finger and toe tips, and a dark brown dorsal chevron. Its advertisement call is a single, moderately long, high-pitched whistle repeated at regular intervals. It is the sister species of P.ravus from Marojejy National Park, but differs from that species by considerable pairwise genetic distances (7.9%) in a fragment of the mitochondrial 16S rRNA gene, and also in bioacoustic and morphological features, especially the absence of yellow on the posterior abdomen. It is also surprisingly similar in external appearance to Cophylaoccultans and C.maharipeo, to which it is not, however, closely related; these species are most easily discerned based on their calls. Platypelisandosp. nov. joins the ranks of several species recently described from Ambodivoangy with close affiliations to species in the nearby Marojejy National Park, that are still divergent at species level. The species qualifies as Critically Endangered according to the IUCN Red List criteria, in line with other species recently assessed from this area, but we urge that more research be conducted in the nearby forests to extend the range of this and other species known only from Ambodivoangy.
