Callilepis schuszteri

Callilepis schuszteri is a species of spider in the family Gnaphosidae. It has a wide Holarctic distribution, being found across Europe, Turkey, the Caucasus, Russia (from the European regions to the Far East), China, Korea, and Japan.^[1]

The species was originally described as Gnaphosa schuszteri by Otto Herman in 1879 from specimens collected in Hungary.^[2] It was later transferred to the genus Callilepis by Chyzer & Kulczyński in 1897.^[3]

Two junior synonyms were established by Norman I. Platnick in 1975: Pythonissa flavitarsis Simon, 1880 and Callilepis bipunctata Yaginuma, 1960.^[4]

C. schuszteri has one of the widest distributions among Callilepis species, spanning the Palearctic realm from Western Europe to East Asia.^[1] It is found throughout Europe, extending into Turkey and the Caucasus region, and across Russia from the European territories to the Far East. The species also occurs in China, Korea, and Japan.^[1]

Based on Herman's original description, the species inhabits dry, rocky areas and appears to be adapted to arid environments. It runs fast.^[2]

Callilepis schuszteri is a medium-sized ground spider. According to the original description by Herman (1879), females have a body length of approximately 5.8 mm, while males are smaller at about 4.3 mm. The cephalothorax is relatively narrow with a distinctive pattern, and the abdomen shows characteristic coloration. The species exhibits typical gnaphosid features including robust legs adapted for ground-dwelling habits.^[2]

The female displays a predominantly dark coloration with yellowish markings, while the male is generally smaller and more slender with distinctive pedipalpal structures used for identification.^[2]
