Hemidactylus is a

cryptic species complexes are found.[2] Geckos like to live in and out of houses. They have been introduced to Australia.[citation needed
]

This species is closely related to the genus Gehyra, which belongs to the same family in Gekkonidae.

The species are typically known as house geckos, due to their readiness to adapt to and coexist with humans, and can be easily encountered in human habitations.

Taxonomy

This genus was originally established by Lorenz Oken in 1817 for the species at that time known as Hemidactylus tuberculosus, and now described as the tropical house gecko (Hemidactylus mabouia).[2] The species name in turn comes from the Greek words ἡμι hemi "half" and δάκτυλος dáktylos "fingers" because its toes has split or "half" lamella underneath them.[6]

Evolution

The origin of the genus Hemidactylus is still unclear as the higher level phylogeny is not well resolved. Moreover, much of the diversity in this group still remains to be discovered.

Feces

A house gecko will usually confine its excretions to one area of a house. This is sometimes considered a nuisance by home owners, and may stain certain surfaces.[7] The feces are approximately five (5) millimeters in length, two (2) millimeters wide, and dark brown (almost black) in color.

Description

Foot upperside (left) and underside of the Oriental leaf-toed gecko (H. bowringii).

The

dorsal lepidosis is either uniform or heterogeneous. The pupil of the eye is vertical. Males have pre-anal or femoral pores. Each finger or toe has a slender distal clawed joint, angularly bent and rising from within the extremity of the dilated portion.[8]

The fingers and toes are free, or more or less webbed, and dilated; underneath they bear two[

Some members of the genus, such as H. platyurus, are able to run

bipedal gait of basilisks.[9]

Communication

Like many other gecko species, species in the genus Hemidactylus are able to communicate with distinct vocalizations. Depending on the species, their vocalizations range from quiet clicks to short squeaks and chirps. For example, the Asian common house gecko (Hemidactylus frenatus) is notable for its distinctive chirping.
