CAC143B2627D5F85AF40B13A7ACA925D.taxon	diagnosis	Diagnosis. This species in Miocene amber from Ethiopia was originally placed in the genus Dactylurina. It differs quite notably from Dactylurina and is therefore here removed to a new genus. The fossil genus differs from Dactylurina in the absence of a basal sericeous area on the retrolateral surface of the metabasitarsus (such an area is present in Dactylurina), the metasoma that is roughly cylindrical and tapers apically (metasoma greatly elongate, finger-like, and subclavate in Dactylurina), face not wider than compound eye length (wider than compound eye length in Dactylurina), and two preapical teeth of the mandible (unidentate in Dactylurina).	en	Engel, Michael S., Rasmussen, Claus, Ayala, Ricardo, de Oliveira, Favizia F.

CAC143B2627D5F85AF40B13A7ACA925D.taxon	etymology	Etymology. The new genus-group name is a combination of the Ancient Greek alpha privative a - / ᾰ ̓ -, indicating negation, and Dactylurina Cockerell [itself a combination of the Latin adjective dactylus, meaning, " finger-like " (from Ancient Greek daktulos / δᾰ ́ κτῠλος, meaning, " finger "), and the noun ūrīna, meaning, " urine " but also referring more generally to " genitals " or even metaphorically to the " tail end " through its Ancient Greek origins from the word oura ́ / οὐρᾱ ́, meaning, " tail "], the genus to which the species was originally placed. The gender of the name is feminine. † A. aethiopica (Lepeco & Melo), comb. nov.	en	Engel, Michael S., Rasmussen, Claus, Ayala, Ricardo, de Oliveira, Favizia F.
