Agamura persica

Persian Spider Gecko (Agamura persica)

The Persian spider gecko, scientifically known as Agamura persica, is a distinctive reptile native to the semidesert regions of Iran, Pakistan, and Afghanistan. Its common name is derived from its unique physical characteristics, particularly its long, slender legs and tail, which lend it a spider-like appearance and aid in navigating its rocky habitat. This adaptation allows it to climb effectively on the stony terrain it inhabits.

Natural History and Habitat

This gecko thrives in arid environments, specifically rocky and stony areas found on hill slopes and barren plains. While primarily a nocturnal species, the Persian spider gecko can be observed during the day, particularly when basking. It seeks out temperatures around 17.5 °C (air) and 15.5 °C (surface) for basking and can remain active at surface temperatures as high as 44 °C. A notable adaptation for its potential diurnal activity is its well-developed, though immovable, upper eyelid, which functions as a sunshade.

Physical Characteristics and Reproduction

Adult female Persian spider geckos typically range from 42 to 77 mm in snout-to-vent length (SVL), with a tail length of 34 to 59 mm. Males are slightly smaller, measuring between 35 to 65 mm SVL with a tail length of 27 to 59 mm. The gecko's coloration consists of a light-grey upper body accented with yellow pigment, featuring five dark crossbars that are nearly as wide as the spaces between them. The tail bears nine to ten similar crossbars, and the belly is a flecked grey. Sexual dimorphism is apparent; males possess a noticeable hemipenal bulge and two to four preanal pores, whereas females lack these features. The species reaches reproductive maturity at 18 to 24 months of age. The breeding season spans from March to May, with eggs laid in June, and the emergence of juveniles typically occurs in September.

Taxonomy

While Agamura persica is the accepted scientific name, two other species, Agamura femoralis and Agamura misonnei, were once placed in the same genus. However, taxonomic revisions by Anderson (1999) and Khan (2003) have reassigned these species to the genus Rhinogekko. Two subspecies are recognized: Agamura persica ssp. persica, found in eastern Iran and Afghanistan, and Agamura persica ssp. cruralis, prevalent in western Iran. The subspecies differ in the number and intensity of their dorsal crossbars.
