Etymology. This species is named in honour of Charles W. and Lois B. O ’ Brien, collectors of the type series of this species.

Diagnosis. The bicoloured body, the presence of a longitudinal carina on pronotum ( Figure 19) and the male genitalia ( Figure 23) helps to distinguish Aporrhipis obrieni from other species in the genus.

Description. General colour dark brown ( Figure 19); head, scape, pedicel, base of antennomere III, humeral region and legs yellow ( Figures 19, 21). Antennae reaching apex of elytra, densely setose; flabellum of antennomere III subequal in length stem; flabellum of antennomere IV 1.5x longer than stem; flabellum of antennomere V about 2x longer than stem; flabella of antennomeres VI – X about 4x longer than respective stem. Pronotum bearing a longitudinal carina ( Figure 19). Elytra: subparallel, 8x longer than pronotum; reticulation vestigial and hardly identifiable, with four elytral costae, costae I and II weakly developed, no reaching apex of elytra; costa III and IV reaching apex of elytra, connected at apex. Legs: slender, elongate; trochanters tubular; femora and tibiae elongate, femora subparallel, tibiae clavate. Male genitalia bilaterally symmetrical; exposed portion of median lobe subequal in length of parameres, slightly expanded towards apex, rounded apically; folds in the basal inner margin of median lobe strongly developed, half the length of exposed portion of median lobe, membranous, with apices acuminate; apices of

parameres hooked; phallobase subequal in length with parameres, lateral margins subparallel, posterior margin round, with median suture absent ( Figure 23).

Length (pronotum+elytra): 3.1 – 3.3 mm. Width (across humerus): 1.1 – 1.2 mm.
