Aetius O. Pickard-Cambridge, 1896

Type species. Aetius decollatus O. Pickard-Cambridge, 1896 by original designation.

Diagnosis. Aetius is most similar to Serendib Deeleman-Reinhold, 2001 and Sphecotypus O. Pickard-Cambridge, 1895 in having wide, strongly recurved posterior eye row and heavily sclerotized abdomen. It can be distinguished from Serendib by the carapace with a posterior protrusion, which projects over the pedicel, subpentagonal carapace with a broad central plateau, which slopes towards the lateral and posterior margins, absence of paired dorsal spines anteriorly on the abdomen, posterior abdomen with tufts of long white hairs, highly sclerotized epigyne, spermathecae I simple and narrow, male palp with straight embolus and baso-retrolateral semi-circular cymbial notch. The genus can be separated from Sphecotypus by the absence of a deep constriction behind cephalic region ( O. Pickard-Cambridge 1896; Dankittipakul & Singtripop 2013).
