Identification
Defining characters of Acrocercopinae include a long intersegmental membrane between the A8 and the external genital organs in males ; a curved forewing anal vein; and a completely red final larval instar. The maxillary palpi of the adult are relatively well developed and four-segmented. The forewing possesses all three medial veins, with two medial veins present in the hindwing; the hindwing is relatively narrow with a maximum width of ∼0.10–0.14× that of its length. The final instar possesses two lateral setae on all segments, five pairs of stemmata (one less than Gracillariinae) and four to five pairs of labral setae (1).
