Diagnosis

Body extensively yellow, brown markings on head just behind eyes, medially on pronotum, mesonotum, metanotum and abdominal tergites II–VII; antennal segments brown, III–V with a narrow pale area basally; legs yellow; fore wing banded, pale in basal third, brown medially; apical third slightly paler; clavus uniformly brown. Head with weak reticulate sculpture, with three pairs of ocellar setae. Antennae 8-segmented, III & IV each with a forked sense cones. Pronotum reticulate, without long setae. Mesothoracic spinula present; metathoracic endofurca weakly developed, without spinula. Metanotum reticulate medially; paired campaniform sensilla absent; two pairs of setae, median pair arising behind anterior margin. Tarsi 2-segmented. Fore wing first vein setal row widely interrupted, second vein setal row essentially complete. Abdominal tergites with reticulation and few and sparse microtrichia on lateral thirds; II–VIII with pair of small setae medially; VIII with posteromarginal comb of microtrichia; IX with rows of fine microtrichia. Sternites without craspeda or discal setae; three pairs of long posteromarginal setae. Both sexes winged.

 

Male tergite IX with two pairs of thorn-like setae; abdominal sternites III–VII each with transverse pore plates.

 

Intraspecific variation

Thorn-like setae reduced in small males.

 

Genus and similar species information

According to Mound & Marullo (1996), it is unclear if one or more species are involved in this genus. Sakimura (1967) treated A. orchidearum as a subspecies of A. orchidaceus and stated that they can be distinguished from each other by the fore wing colour and antennal structure. But variation continues to cause problems (Goldarazena et al. (2008).

 

World distribution

Known from Brazil and Costa Rica.
