RASNITSYN, ALEXANDR P., MAALOUF, MOUNIR, MAALOUF, RAMY & AZAR, DANY, 2022, New Serphitidae and Gallorommatidae (Insecta: Hymenoptera: Microprocta) in the Early Cretaceous Lebanese amber, Palaeoentomology 5 (2), pp. 120-136 : 123-124

Genus Leptoserphites Rasnitsyn & Azar , gen. nov.

Type species. Leptoserphites pabloi sp. nov.; by present designation.

Other species. Leptoserphites iriae sp. nov.

Etymology. The genus name is from Greek λεπτός = leptos means thin + the genus name Serphites .

Diagnosis. Antenna 11–12-segmented, with no club defined. Body comparatively narrow, with mesosoma twice as long as high, forewing with only R, 2r-rs and pterostigma tubular, 2r-rs at least half as long as pterostigma high, no R and RS present as nebulous vein distal of pterostigma and 2r-rs, respectively.

Remarks. The new genus is attributed to Serphitidae and particularly to Supraserphitinae based on antenna 11–12-segmented (vs. 14-segmented in Archaeoserphitidae and less than 11-segmented in Serphitinae and Microserphitinae ). It differs from the type and only supraserphitine genus Supraserphites Rasnitsyn & Öhm-Kühnle, 2019 in having stature narrower, basal flagellomere smallest in 12-segmented antenna (putatively fused with the next one in 11-segmented ones), forewing with RS&M nebulose (vs. tubular) and R and RS lost as colored veins distal of pterostigma and 2r-rs (vs. tubular or nebulous).
