Females without wings or ocelli. Body brown to dark brown, legs and antennal segments III–IV paler. Head, thorax, and at least anterior abdominal tergites strongly reticulate; with no long setae except on tergite IX. Antennae 8-segmented; segments III–IV with sensoria simple. Mesonotum, metanotum and abdominal segment I all strongly transverse. Abdominal tergites V–VII with median transverse row of about 10 setae; tergite VIII with no posteromarginal comb; tergite X with complete longitudinal division. Sternites with median transverse row of about 8 small discal setae.
The genus Prosopoanaphothrips includes only a single species. In general appearance, this wingless thrips resembles some species in Anaphothrips, but in that genus no species have discal setae on the sternites.
Prosopoanaphothrips reticulatus (Moulton)
Breeding on leaves and in leaf axils (Bailey, 1948).
Various Poaceae, particularly Bromus rigidus.
Large populations can result in severe stunting damage to the leaves of its grass host plants (Bailey, 1948).
