Parasyscia wittmeri

This species has been found in soil under a stone in grazed scrubby pasture (Collingwood 1985).

Identification
Sharaf et al. (2018) - Parasyscia wittmeri can be diagnosed by the combination of the following characters: eyes distinctly small with five ommatidia in longest row; petiole appears oval in dorsal view with curved anterior and posterolateral angles; uniform yellow or red-yellow.

This species can be separated from the only other Parasyscia known from the Arabian region by the following couplet:


 * Eyes small with five ommatidia in the longest row (EI 11–18); petiole nearly oval in dorsal view with rounded anterior and posterolateral angles . . . . . Parasyscia wittmeri


 * Eyes larger with 11–12 ommatidia in the longest row (EI 15–30); petiole clearly trapezoidal in dorsal view with acute anterior and posterolateral angles . . . . . Parasyscia rifati
