Additional information on the Giant Himalayan Horned Frog, <i>Megophrys periosa</i> Mahony, Kamei, Teeling & Biju, 2018 (Anura: Megophryidae)

Abstract

In the last decade, there has been a major revision in the cryptic species complexes of the genus Megophrys Kuhl &amp; Van Hasselt (and earlier Xenophrys), resulting in reports of many new species and new records from Arunachal Pradesh, India. Here we report additional information on the morphological variations of the recently described species Megophrys periosa Mahony, Kamei, Teeling, and Biju, 2018 (Anura: Megophryidae) from the surroundings of the type locality. The species was confirmed by generating the 16S rRNA sequences and comparing them with that of M. robusta Boulenger, 1908, a sympatric species with similar morphological characters. A preliminary phylogenetic tree has been made and discussed. Besides updating the altitudinal range for the species, a remark on the type locality is also made.
