Zelotes gabriel

Platnick & Shadab, 1983

Zelotes gabriel is a ground spider in the Gnaphosidae, described by Platnick and Shadab in 1983. It is native to the United States, specifically recorded from southern California and Baja California. Like other members of the Zelotes, it is a hunting spider that does not build webs to capture prey. The species name honors Gabriel, the son of entomologist Walter Leal, who attended the ceremony where his father received the National Academy of Inventors Fellowship.

Appearance

As a member of Gnaphosidae, Zelotes gabriel possesses the characteristic features of ground spiders: a cylindrical , prominent that often project posteriorly, and a with a distinct fovea (depression). The arrangement consists of two rows: the row with four small eyes and the row with two large eyes and two smaller lateral eyes. Coloration is typically dark, ranging from black to dark brown, with possible lighter markings on the abdomen. Specific measurements and detailed somatic descriptions require examination of .
