Calythea micropteryx can be separated from the other species of the genus in having face not projecting beyond frontal angle; parafacialia very narrow, with about 1/5 of postpedicel width ( Fig. 3g ); distance between presutural acrostichal rows, except anteriorly in the first pair of setae, shorter than their distance to dorsocentral rows; hind tibia with a posterodorsal seta twice longer than tibia width. Also, this is the smaller neotropical species (body length: 3.3–3.5; wing length: 3.2–3.5). Type-material examined. Paralectotypes .
