Acoenoniini

Tribe Acoenoniini Pritchard

Pritchard (1960a) introduced this tribe for the genus Acoenonia Pritchard, at that time containing only the typespecies, A. perissa Pritchard. Acoenoniini are clearly distinct from other Micromyinae in both larval (Mamaev & Krivosheina 1993: 81, 89f) and adult (Jaschhof & Jaschhof 2009: 87f.) characters, the latter as follows. The wing membrane has a few or no distal setae; the costal break is situated far before the apex of the wing (Fig. 9E); the apices of the tibiae bear several scalelike, pointed spines marginally (Jaschhof 1998: fig. 42h); and the antennal flagellomeres of males have indistinct crenulate whorls (Fig. 9C). Acoenoniini are thought to be the sister-group of Campylomyzini based on synapomorphies, such as the laterally incomplete eye-bridge and the ejaculatory apodeme modified apically and/or basally (Jaschhof & Jaschhof 2009: 296). Acoenonia is the only genus of this tribe.
