Dogonia Oldroyd, 1970

Dogonia Oldroyd, 1970: 269 . Type species: D. saegeri Oldroyd, 1970: 269 , by original designation

Oldroyd (1970) described this genus for two species from Zaïre ( D. nigra & D. saegeri ). I have not seen this material. Although he says that Dogonia has “ metanotal callosities hairy ” he compares it with Scylaticus , Cyrtopogon and Saropogon , all of which lack setae on the anatergite. He mentions that the genus keys to Neodysmachus in Hull’s key but incorrectly calls Neodysmachus an Australian genus. Despite these confusing comments I believe Dogonia to be a valid genus and use the following features to separate it from Dioctobroma (the only other genus to lack well-developed occipital bristles). Oldroyd's Fig. 44 shows that Dogonia saegeri has a face slightly narrower than the width of one eye in anterior aspect (eye face width ratio 1,39 1) whereas Dioctobrama has a wider face (eye face width ratio 1,03 1). Dogonia has “ antennae with two rather short, subequal segments”, a feature not seen in Dioctobroma where the scape is clearly longer than the pedicel. Males of Dioctobroma flavoterminatum have very reduced fused gonocoxites, quite unlike the condition illustrated by Oldroyd for both species of Dogonia . The genital characteristics are likely to be of generic significance.
