Hemidactylus scabriceps, a gekkonid lizard originally described from the Ramnad district of Tamil Nadu, India,
is recorded from Mannampandal, Nagapattinam district in the same state. This is the third known locality for this
species in India and the first Indian record in 72 years. The species also occurs in Sri Lanka. Data on lepidosis
and natural history, as well as the first life photographs of H. scabriceps are provided.
Keywords: Hemidactylus scabriceps, rediscovery, distribution, Tamil Nadu, Sri Lanka, tropical dry evergreen
forest.
INTRODUCTION
Annandale (1906) undertook a survey in the Ram-
nad (= Ramanathapuram) district of Tamil Nadu with
the intention to explore the fauna of a desert tract in
south India, and compare it with that of the north-west-
ern frontier. In this work he described a distinctive new
gecko, Teratolepis scabriceps. This taxon was later
transferred to a new, monotypic genus, Lophopholis
Smith et Deraniyagala 1934. Thereafter the combination
Lophopholis scabriceps was used in several works, in-
cluding the influential book of Smith (1935). Later,
Lophopholis was synonymized with Hemidactylus
Oken, 1817 by Loveridge (1947), based on similarities
in digital structure. The combination Hemidactylus sca-
briceps (Annandale, 1906) has since been widely, but
not universally employed for this taxon, as authors like
Das and Andrews (1997), Das and de Silva (2005), de
Silva (1996, 1998), Kluge (1991, 1993, 2001), Love-
ridge (1947), and Rösler (2000) accepted it as Hemidac-
tylus scabriceps, while others like Murthy (1990) and
Tikader and Sharma (1992) retained it as Lophopholis
even after Loveridge’s (1947) allocation of it to Hemi-
dactylus (Bauer et al., 2008). Bauer et al. (2008) sug-
gested that this species was closely allied to those
Hemidactylus formerly allocated to the genus Terato-
lepis as they share imbricate scalation, a rare condition
among geckos. Deraniyagala (1949) gave its Sinhalese
name as “Korapothu huna”[Korapothu = scales; huna =
gecko] (fide Ruchira Somaweera, personal communica-
tion), an early recognition of its unusual (i.e., imbricate)
scalation. Smith (1935) and Murthy (1990) state that it is
a nocturnal species, inhabiting sandy sea shores and it
has been recorded from Adiyar, Madras (now Chennai),
and Mariccukatte, Northern Province, Ceylon (now Sri
Lanka) as well as the type locality Ramnad (then in
Madura dist.), Tamil Nadu, India. Murthy (1990) re-
marked that it was rare and that practically nothing was
known about its life history. Wickramasinghe and
Somaweera (2008) surveyed throughout Sri Lanka for
geckos but did not find H. scabriceps.
MATERIAL AND METHODS
A live subadult female was observed on 7
th
Decem-
ber 2006 at 17:13 during a herpetological survey near
Anbanadhapuram Vahaira Charity (A.V.C.) College
campus (Mannampandal village). Meristic, mensural,
and color pattern data were recorded. Mensural data
were recorded using slide calipers (L.C. = 0.3 mm) and
the values were reported in mm. All photographs of the
gecko (except Fig. 1a) were taken in life and in situ, us-
ing Canon Powershot A640 and Canon EOS 400D
model cameras. Geographic coordinates and altitude (in
meters) of Mannampandal were determined from Gar-
