Hemidactylus garnotii, commonly known as the Indo-Pacific gecko, Garnot's house gecko or the fox gecko, is a species of gecko found in India, the Philippines, Southeast Asia, Australia, and throughout Polynesia. Adults are about 4 to 5 in (10 to 13 cm) in total length (including tail). They are seen as dark gray or brown with light markings in daylight and a pale, translucent colour at night. The belly is orange or yellow. The head has a long, narrow snout, hence the name fox gecko. The flattened tail has a row of spiny scales on the lateral edges. The species is parthenogenic – all individuals are female and lay eggs that hatch without requiring male fertilisation.[2]

In Hawaii, the species is thought to be a long-term resident. Formerly considered a house gecko, it has been displaced to natural habitats by the more recently arrived common house gecko.[2] In Florida and Georgia it has become established as an invasive species of concern.[3][4]

Etymology

The specific name, garnotii, is in honor of French naturalist Prosper Garnot.[5]

Description

Snout obtusely pointed, longer than the distance between the eye and the ear-opening, 1.5 to 1.6 times the diameter of the orbit; forehead slightly concave; ear-opening small, rounded. Body and limbs moderate. A slight but distinct fold of the skin along the flanks, and another bordering the hind limb posteriorly. Digits free or with a very slight rudiment of web, moderately dilated, inner well developed; infradigital lamellae oblique, 6 or 7 under the inner digits, 10 to 12 under the fourth finger, and 11 to 14 under the fourth toe. Upper surfaces and throat covered with minute granular scales, a little larger on the snout; abdominal scales moderate, imbricate. Rostral subquadrangular, with median cleft above; nostril pierced between the rostral and three nasals; 12 or 13 upper and 9 to 11 lower labials; mental large, triangular, in contact posteriorly with a pair of pentagonal chin-shields, followed by a second smaller pair; the anterior pair of chin-shields in contact with the first infralabial, and with each other mesially; the posterior pair separated from each other, and also completely or nearly completely from the labials. Tail depressed, flat beneath, with sharp denticulated lateral edge; the scales on the upper surface very small, equal; those on the lower surface larger, imbricate, with a median series of large, transversely dilated plates.[6]

Brownish grey above, uniform or with more or less distinct brown and whitish spots; lower surfaces uniform whitish.[6]

Snout to vent length (SVL) 2.3 in (5.8 cm); tail 2.6 in (6.6 cm).[6]

Reproduction

H. garnotii is a parthenogenetic species.[7]
