Diagnosis and history

This species was described as Epilampra pallida from a female specimen, whose habitus was described and drawn (Borg 1902). Its junior synonum Epilampra minuta was described in the same work, from a male and a female specimen. Note that Borg apparently described the species from two female specimens but he also reported drawing a male specimen, which was later confirmed by Princis (1963a) who illustrated the male subgenital plate and tergal specialization (near the junction of tergites VIII–IX). The shape and localization of this tergal gland is diagnostic (Kumar 1975).

Measurements of adults

Female (n = 3): pronotum length ×width: 4.5–5.6 ×5.9–6.9, tegmina length: 19.2–22.2, overall length ×width: 17.2–23.4×7.5–8.7.
