Abstract
A population of Hemidactylus cf. frenatus Duméril & Bibron, 1836, was recorded from Tyda and its vicinity in the Ananthagiri Hills, northern Eastern Ghats, Vishakhapatnam District, Andhra Pradesh, India. Evaluation of morphometric and meristic characters supported by karyotyping revealed that populations from the Ananthagiri Hills are considerably different from other populations of H. frenatus occurring in India. We provide the detailed description of the male of this divergent population.
Highlights
IntroductionThe genus Hemidactylus Oken, 1817, belongs to the second most speciesrich lizard family in the world, Gekkonidae, with 100 species being described till date (Pough et al 2000; Carranza & Arnold 2005; Krysko & Daniels 2005; McMahan & Zug 2007; Giri 2008; Giri & Bauer 2008; Giri et al 2009; Mahony 2009; Uetz 2010)
It has been observed that a great majority of representatives of Hemidactylus geckos are restricted in distribution and confined to southern Asia and Africa, with only eight species namely H. brookii, H. bowringii, H. flaviviridis, H. frenatus, H. garnotii, H. persicus, H. mabouia and H. turcicus colonizing most of the geographical extent of this genus (Kluge 1969; Carranza & Arnold 2005)
In the present paper we report the discovery of a morphologically and chromosomally divergent population of the H. frenatus species complex from the northern Eastern Ghats, Andhra Pradesh, India

From the state of Andhra Pradesh alone 11 species represent the genus Hemidactylus (Murthy 1986; Rao et al 2005; Srinivasulu & Das 2008; Mahony 2009)
