Identification

Recognised by the labrum with 4 – 6 digits, scape and legs yellow, facial sculpture reticulate, vertex rugulose, mesosoma coarsely rugose-areolate and bluish green with reddish dorsal patches, and fore wing pilose but with the basal area and speculum bare and the speculum open basally, and the hind wing with reduced setation, both in size and numbers, in the basal half. Of the specimens where it could be observed, the variation in labral digits ranged in females from 4 (4 specimens), 5 (3) to 6 (3), and in males from 4 (13), 5 (8) to 6 (8).

Distribution

Costa Rica

Nomenclature
