Lahulus Navás, 1930

Type species. Lahulus babaulti Navás, 1930: 9 (by original combination).

Diagnosis. Prothorax slightly longer than wide; wings hyaline with yellow venation, narrow with obtuse apex, posterodistal wing margin convex; pterostigma with brown marks; outer gradate series distinct, remainder of crossveins irregularly arranged; Cu forked at wing base; FW RP with 13–15 branches, slightly curved with bifurcated apex; FW subcostal area with most veinlets forked, those in the distal half somewhat sinuous; a single crossvein between R and M veins; CuA with three branches; some maculae present in cubital region; HW costal area narrow at base with only few costal crossveins forked; RP with 13 branches; male ectoproct sub-triangular with hook shaped ventral projection; male abdomen yellow with yellow setae.

Comments. The monotypic genus Lahulus Navás is known only from the original description and neither the type or additional specimens of the sole species have been located in the Muséum National d’Histoire Naturelle, Paris. Little is discernible about this genus from the description by Navás (1930), but he does state a clear similarity with the genus Hyposmylus Krüger , a genus now considered a synonym of Osmylus . According to Navás description, Lahulus has the simpler costal area and more reticulated pterostigma when compared to Hyposmylus . We cannot immediately conclude Lahulus is a synonym of Osmylus though, as the male genitalic drawing by Navás (1930), albeit simplistic, is unlike any other found in the family; it will require further examination to determine the validity of the genus.
