Data from: A new species of Coryphophylax fitzinger in: Steindachner, 1867 (Sauria: Iguania: Agamidae) from the Andaman Islands, India

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.
