Some paratypes are duller in overall appearance (Plate 3). PLATE 3. Type series of Cnemaspis girii sp. nov. Table 1. Mensural and meristic data for the type series of Cnemaspis girii sp. nov. Abbreviations as stated in Materials and Methods, * = damaged. Etymology: The specific epithet is a patronym, honouring Dr. Varad Giri of Bombay Natural History Society for his immense contribution to Indian herpetology and continued support to the authors. Distribution and natural history: Of the nine specimens of the type series, seven were collected from under boulders and two were collected from tree hollow ca. 2m above ground. The specimens were only seen along a stream which is surrounded with dense evergreen riparian forest (Plate 4 c & d). All specimens were collected during the day during two different seasons (February and July) and were found to be inactive. Efforts made in three different seasons (monsoons, winter and summer) by us and Chikane & Bhosale (2012) to locate this species in the adjoining plateau were futile suggesting that this species occupies only the forested track along the stream. Forest microhabitats are more stable as opposed to the exposed plateau which is extremely harsh during summer when it dries completely. This probably restricts Cnemaspis girii sp. nov. and several other species to the forested areas. Sympatric species such as Geckoella deccanensis, Rhabdops olivaceus, Indotyphlus maharashtraensis, Raochestes ghatei were observed. (Chikane & Bhosale 2012). Kaas plateau is located about 25 km northwest of Satara City at an altitude of about 1240 m a.s.l (Fig. 3, Plate 4 a). The region is a lateritic rock outcrop and is characterized by relatively extreme conditions with highly patchy and temporally variable resources. The average annual precipitation is between 1,723 and 1,865 mm, and is limited to the monsoon season, which is when expansive water-logged areas are created that support a wide range of floral and faunal life. Most of this water subsequently runs off on the thin soil cover, causing drastic habitat changes towards the end of rainy season. Winters and summers are dry save for sporadic pre-monsoon showers towards the end of summer. Temperatures can be as low as 4–6 °C in winter and reach 55 °C on rock and soil surfaces in summer at air temperatures of up to 45 °C (Watve & Thakur, 2006, Mirza et al. 2013 a). The plateau is thickly covered with vegetation during the monsoons, most of which dries up during the period of October-May, leaving behind dry grass interspersed with a few clusters of bushes. The microclimatic conditions vary from almost xeric to water-logged during the course of a year (Watve & Thakur, 2006) and so create an extremely harsh physical environment for all life forms. Another species which has been described from similar biotope is Hemidactylus sataraensis Giri & Bauer, 2008 which is found on similar plateaus in an area less than 8 sq. km. (Giri & Bauer 2008, Mirza et al, 2013 b). The plateau is well known for its floral diversity which attracts tourists, and excess visitorship is of an immediate concern as a threat to this unique habitat. Kaas will likely benefit if it is elevated to the status of a wildlife sanctuary, which will eventually provide it with more protection. PLATE 4. Habitat of C. girii sp. nov. at Kaas plateau.
