Amerostenini

Amerostenini Bouček, 1988. Type genus: Amerostenus Girault, 1913.

Diagnosis.

Antennal flagellum with 4 anelli and 4 funiculars (Fig. 87 ). Pronotum not medially divided. Ovipositor sheaths not expanded.

Discussion.

Molecular data indicate that the previously mentioned ( Bouček 1988) unusual morphology of Yrka dahmsi Bouček new placement suggests that it belongs in the tribe Amerostenini in Colotrechninae instead of in Coelocybidae .

Morphology is consistent with this change, given that Yrka and some Amerostenini share a count of 4 antennal anelli.
