Abstract:
The Hemidactylus brookii group taxon has received increased attention in recent years from systematists and taxonomists attempting to unravel the complicated issues of its synonyms. In this study, a morphological approach is adopted to reexamine the syntypes of Hemidactylus brookii and Hemidactylus subtriedroides. The syntype series of H. brookii is found to be composed of two morphologically distinct species. A Borneo syntype is designated as lectotype and redescribed in detail to provide taxonomic and nomenclatural stability for the species. A syntype of H. subtriedroides is designated lectotype and also redescribed in detail, along with additional populations, which includes the Australian paralectotype of H. brookii sensu lato. Hemidactylus subtriedroides is morphologically distinct from H. brookii sensu stricto, but indistinguishable from the recently elevated synonym Hemidactylus tenkatei with which it is here considered a junior subjective synonym. Neotypes are designated for the two Pakistan synonyms, Hemidactylus kushmorensis and Hemidactylus glead-

Abstract:
We present an expanded ND2 phylogeny of the brookii and prashadi groups of Indian Hemidactylus. While relationships within the clades are not well resolved, we recover many well supported subclades and a number of deeply divergent lineages within each clade. We use morphological data to describe three of these divergent lineages as new species; Hemidactylus kolliensis sp. nov., a member of the prashadi group from high elevation in the Kollimalai Massif in Tamil Nadu, Hemidactylus chikhaldaraensis sp. nov. and Hemidactylus sankariensis sp. nov., both members of the brookii group, are described from high elevation of the Satpuras in Maharashtra and low elevation of Tamil Nadu, respectively. The three new species exhibit >15% divergence for the ND2 gene from their phylogenetic sisters and differ in a number of morphological characters from all Indian congeners. The discovery of three more endemic Hemidactylus species from rocky habitats suggests that many more remain to be discovered across India.

Abstract:
We describe a new species of Hemidactylus based on an integrative taxonomic framework from scrub habitats at the southern tip of India, in Thoothukudi District, Tamil Nadu. The new species has the most densely packed tubercles among Indian Hemidactylus, almost resembling the most tuberculate Indian Cyrtopodion. Hemidactylus quartziticolussp. nov. is phylogenetically placed within the brookii group of Indian Hemidactylus, where it is sister to the H. gleadowi complex from western-central India. The new species is 14.5–23.7% divergent in ND2 mitochondrial sequence data from other brookii group members, and can be easily diagnosed from regional congeners by its unique dorsal scalation, the number and arrangement of precloacal-femoral pores, the number of dorsal tubercle rows at midbody, number of lamellae under digit I and IV of manus and pes. The new species is currently known only from two isolated, low quartzite hillocks 45 km apart with scrubby, thorn forests and loose, stony soil.

Abstract:
A total of 25 wall lizards (15 Hemidactylus brookii brookii and 10 H. platyurus) were examined for nematode parasite Neopharyngodon sp. from Kirtipur, Nepal. Neopharyngodon sp. were taxonomically identified and showed characteristics like small size (1.375-1.5mm x 0.225-0.25mm), mouth with two lips, oesophagus (0.35mm x 0.03mm), oesophagus bulb (0.092mm) and pointed tail with size one-third of the whole body length. Twenty percent of H. brookii brookii harbored the nematode parasite with average parasitic intensity of 4.3 while 80% of H. platyrus showed Neopharyngodon sp with parasitic intensity of 4.Journal of Institute of Science and TechnologyVol. 21, No. 1, 2016, Page: 52-55

Abstract:
Two distinct species of the gekkonid genus Hemidactylus are described from the dry zone of peninsular India from the state of Telangana. The two sister species, Hemidactylus flavicaudus sp. nov. and H. xericolus sp. nov., are nested within the morphologically cryptic H. brookii group, but are clearly distinguishable from all known species in having a bright yellow tail and yellow markings on the head, besides unique combinations of meristic characters and small body size (< 45 mm snout to vent length). The two new species are also deeply divergent from each other and other members of the H. brookii group in mitochondrial NADH dehydrogenase 2 and cytochrome b sequences. Hemidactylus flavicaudus sp. nov. can be diagnosed from H. xericolus sp. nov. based on the number of dorsal tubercle rows at midbody (11–14 versus 6–8). These descriptions of evolutionarily and morphologically distinct species highlight the dearth of studies carried out in the dry zone of peninsular India and the urgent need to assess biodiversity in the face of rapid land-use changes in this landscape.

Abstract:
A new rupicolous gecko from the Hemidactylus brookii complex is described from the forests and plateaus of Amboli, in the Western Ghats of Maharashtra. This medium sized (average adult SVL 56.2±5.0 to at least 62 mm), nocturnal species is superficially similar to other congeners from the ‘H. brookii’ clade, but can be distinguished from them in having 17 or 18 fairly regular longitudinal rows of enlarged, conical, keeled tubercles at midbody, extending from posterior part of the head to groin; tubercles in parasagittal rows smaller, feebly keeled and more rounded; approximately six rows of tubercles on either side of parasagittal tubercle rows, highly enlarged, remarkably conical and strongly keeled; lamellae divided in a straight transverse series—seven or eight lamellae beneath fourth digit (manus and pes) and five or six beneath first digit (manus and pes). Males with nine or ten (rarely eight) femoral pores separated by four or five poreless scales; supralabials 11–13; infralabials 8–11. Molecular data based on the mitochondrial ND2 gene supports the distinctiveness of this species and helps ascertain its phylogenetic position within the ‘H. brookii’ group of the Indian Hemidactylus radiation.

Abstract:
Two new species of geckos from the genera Cnemaspis and Hemidactylus are described from a granite outcrop in the Rishi Valley, Chittoor District, Andhra Pradesh, India. Cnemaspis rishivalleyensis sp. nov. and Hemidactylus rishivalleyensis sp. nov. are presently known only from their type locality and are 8.7 % and 10.9 % divergent from their closest known sister species, respectively. The new species are allied to the mysoriensis and murrayi clades of South Asian Cnemaspis and the brookii group of Indian Hemidactylus, respectively. The two new species can be diagnosed from regional congeners by the number and arrangement of femoral and precloacal pores and poreless scales separating these series, body size, the number of tubercles in paravertebral rows, the number of enlarged tubercles around mid-body, the number of ventral scales across mid-body, the number of lamellae beneath digit IV of pes and manus, and subtle differences in colour pattern. Four endemic geckos now have their type localities within 10 km of each other, Cnemaspis graniticola and Cyrtodactylus rishivalleyensis from Horsley Hills and the two new species from Rishi valley. The two new species are also the third endemic species each of Cnemaspis and Hemidactylus from Andhra Pradesh.

Abstract:
AbstractHemidactylus brookii was the most common gecko in the Terai of central Nepal, occurring both in the forest and on buildings. In the Royal Chitwan National Park, samples of adult males (46.4 ± 0.04 mm SVL) were not significantly different from adult females (45.3 + 0.04 mm SVL) in body size and head measurements, except head width (males 9.1 ± 0.2 mm, females 8.7 ± 0.1 mm). All measures of head size were significantly different between sexes when the effect of body size was removed. Males were sexually mature at 42 mm SVL and females at 43 mm SVL. The reproductive pattern of both species is vernal; activities are concentrated in spring (premonsoon). Growth averaged 0.8 mm/month between premonsoon and postmonsoon sampling periods. Adult survivorship was estimated at 14.3% for this six month period. Population size was estimated at 105 lizards on six small buildings in a < 1 ha area. Peak activity period was 1900-2300 h. Hemidactylus brookii in Nepal appears to possess life history characteristics associated with annual population turnover.
