Type species.

Plectrocnemia senex Stephens, 1836.

Description and diagnosis.

Ocelli absent. Filiform antennae about as long as forewings or shorter. Maxillary palps each five-segmented with the 1st and 2nd segments much shorter than the 3rd segment, terminal segment longest and annulated. Plectrocnemia adults with complete forewing venation, apical forks I, II, III, IV, V present; fork I petiolate and fork II sessile; discoidal and median cells closed; crossveins r, s, r-m, and m usually present. In hind wings apical forks I, II, V present, fork I petiolate and fork II sessile; discoidal cell closed. Tibial spur formula 3/4/4.

The two new Plectrocnemia species are very similar and differ clearly in the one-segmented inferior appendages which are robust and short or long.
