A New Megophrys Kuhl and Van Hasselt (Amphibia: Megophryidae) from southwestern Sumatra, Indonesia

Abstract

Megophrys lancip sp. nov., from the Bukit Barisan mountain range of southwestern Sumatra, Indonesia, is described on the basis of molecular and morphological evidence. The new species is distinguished from its congeners in Sumatra, Java, Borneo, and the Philippines by having a medium-sized body, snout with an extremely pointed rostral appendage, a medium-sized triangular eyelid appendage, a dorsolateral fold extending from just behind the eye to the groin, vomerine teeth, vocal slits, nuptial pads on the dorsomedial surface of the first and second fingers in males, and in lacking a Y, X, or H-shaped fold on the dorsum. Morphologically, the new species is most similar to M. montana, but it has a longer rostral appendage, shorter eyelid appendages, and less developed toe webbing. We also evaluate the taxonomic status of M. parallela and comment on the occurrence of M. aceras in Sumatra.

Out of the trap: A new phytothelm‐breeding species ofPhilautusand an updated phylogeny of Bornean bush frogs (Anura: Rhacophoridae)

“…Its high species richness makes Borneo one of the global hotspots for amphibian diversity (de Bruyn et al, 2014). In particular, unraveling the complexes of so‐called “cryptic” species accounts for a major part of the new species descriptions in recent years from Sundaland (e.g., Arifin et al, 2018; Dehling et al, 2016; Hamidy & Matsui, 2014; Hamidy et al, 2012; Matsui et al, 2010, 2016; McLeod, 2010; McLeod et al, 2012; Munir et al, 2018; Shimada et al, 2011; Waser et al, 2017). Alongside this hidden sphere of amphibian diversity, unexpected discoveries of completely new frog species (with obviously distinct morphology and life history) were also reported in Borneo during the last decade (e.g., Ansonia vidua, Hertwig et al, 2014; Chiromantis inexpectatus, Matsui et al, 2014; Glyphoglossus capsus, Das et al, 2014).…”

A new species of Microhyla (Anura: Microhylidae) from Sumatra, Indonesia

“…Sumatra had been explored for its amphibian diversities for long decades, but new species are continuously discovered from this Island until now. At least two new endemic genera (Sigalegalephrynus and Sumaterana) and 14 species of frogs have been described from this island in the last five years (Matsui et al, 2014;Riyanto & Kurniati, 2014;Streicher et al, 2014;Hamidy & Kurniati, 2015;Smart et al, 2017;Wostl et al, 2017;Arifin et al, 2018aArifin et al, & 2018bMunir et al, 2018). The finding of Microhyla gadjahmadai sp.…”
