Mandible approximately 3.0 × as long as basally wide, teeth subequal. Malar space about 1.1 × as long as basal mandibular width, coriaceous. Antennal flagellum with 15 flagellomeres. Face, frons, vertex and gena coriaceous and sub-polished.

Further Remarks
We have examined the type of A. pusilla and found that it is a typical A. melanaria. It should be noted that in the original description (Masi 1933), A. pusilla was compared with Aneuclis brevicauda (Thomson, 1889) and Probles exilis (Holmgren, 1860), but not with A. melanaria.
