[Herpetology • 2012] Coryphophylax brevicaudus • A New Species of Coryphophylax Fitzinger in: Steindachner, 1867 (Iguania: Agamidae) from the Andaman Islands, India




ABSTRACT 
The systematic position of the agamid genus Coryphophylax (Squamata: Agamidae) is given as monotypic and endemic to the Andaman and Nicobar Islands in the Bay of Bengal, India. After having surveyed intensively in thirteen different Islands and examined several individuals in the Andamans group of islands, we describe a second species of Coryphophylax from the lowland rainforests of the South Andaman Island. Coryphophylax brevicaudus sp. nov. is differentiated from its congener, C. subcristatus (Blyth, "1860" 1861) by its smaller size, relatively shorter tail, presence of nuchal and dorsal crests in both sexes, midbody scale row counts and colour pattern. The new species lives in sympatry with C. subcristatus. The taxonomic history and systematic status of the genus Coryphophylax are discussed, and the need for continued surveys in the Islands is emphasized.

Key words: Squamata, Iguania, Agamidae, Coryphophylax brevicaudus sp. nov., Andaman Islands, India

[Herpetology • 2013] Pseudocalotes andamanensis • Rediscovery of Calotes andamanensis Boulenger, 1891, from the Andaman Islands (India), and Assessment of its Generic Allocation




The little known draconine agamid lizard Calotes andamanensis Boulenger, 1891, was rediscovered from the Andaman Islands (India). The authors present morphometric and meristic data from six specimens originating from three islands of the Andaman Archipelago, and thereby add information to the description of the type specimen. The lizard's external morphology suggests that its generic assignment to Calotes in its present definition can-not be maintained and that this species should better be included in the genus Pseudocalotes.
