Efferia benedicti (Bromley)

The pupal case of a female Efferia benedicti was described by Dennis & Lavigne (1976a) based on a case from which an adult female was observed emerging from the case on July 17, 1969, 16 km south of Shoshoni , Wyoming, by R. J. Lavigne. The case, without the associated adult, is deposited in the United States National Museum. The description should be modified to include: prothoracic spiracle slightly upraised and facing posteriorly; abdominal spiracles circular, reddish brown, upraised along midline laterally; abdominal segment 9 with pair of long, straight to slightly apically recurved dorsal posterolateral processes, pair of short ventral posterolateral processes (previously called median lateral processes) not basally fused to but slightly curved toward dorsal posterolateral processes; pair of short, terminal ventromedian processes .
