- (Borkent, 2014). Several descriptions of the immature stages are incomplete and lack of SEM study or micro-photographs except in case of A. amazonica and A. schnacki (Diaz et al.,
- 2015), thus comparison with other species or construct a world key remains inconclusive.
- and A. splendida but differs in number of teeth in epipharyngeal combs. The caudal segment of A. formosana contains 4 pairs of long setae, of which 2 pairs exceeds the length of the segment which contradicts the generic limit of Elson-Harris & Kettle (1985). The pupa of A.
- Borkent (2014) published a pupal diagnosis of this genus based on the specimens belonging to the Nearctic, Central America (Costa Rica) and Australian regions. Reexamination of all available specimens by Borkent (2014) revealed sensillum D-7-IV located between the D-8-
- IV and D-9-IV sensilla which is absent in A. formosana. The character i.e. absence of D-7-IV sensillum in the species is shared with family Chironomidae (Borkent, 2012) which probably indicates synapomorphy. A correlation between the relative length of the scutellar setae of the pharate adult and the relative length of the posteromedial projection of the mesonotum was pointed by Borkent (2014). In several species of Forcipomyia, the scutellar setae present in pharate are long but in this species the seta are relatively small despite the posterior mesonotum completely divides the metathorax medially.
