. . . . . . . . . . . .Hapalaraea Thomson The genera of the tribe Coryphiini are largely
from Hatch (1957) where most of them are
illustrated. The key to the genera of the Anthophagini is taken from the paper by Moore (1966) in which a member of each genus is
illustrated. The generic name Elonium Leach is used to replace Acrolocha Thomson following Herman (1970). Some of the species listed in our
catalogues under the name Omalium
Gravenhorst do not have
the metasternum carinate. New genera will be required for them. Key to the Genera of Leptotyphlinae 1. Gular sutures united in front .
