The genus Stedocys was known only from males. Here
we describe the first females of the genus. Stedocys
genitalia are atypical for Scytodidae. Males are distinguished by having the
papal tarsus subequal or smaller than the tegulum, not prolonged apically,
without prolateral blunt macrosetae; the tegulum long, inserted apically on the
tarsus; embolus slightly shorter than bulb, aciculate distally, and females by
lacking fovea or positioning ridges below the epigastric furrow, and by having
an anterior epigynal pouch. In this contribution, we describe the female
and redescribe the male of Stedocysleopoldi (Giltay, 1935), and describe
male and female of Stedocys pagodas new species from China
(Yunnan). The
lack of a projection on the male palpal tarsus suggests that Stedocys is the sister group of all
other genera of Scytodidae.
