Formibelle gen. nov. Sohail & Zhang

Type species: Formibelle vladimiri sp. nov., here designated.

Diagnosis. Formibelle gen. nov. can be differentiated from other caliscelid genera by convex coryphe; large bluish spot on forewing and genital style with hump-like process below capitulum.

Description. External morphology ( Figs 1–4 ). Metope convex joining coryphe at more than 180 o (in lateral view), longer than wide, narrowing towards clypeus with obscure carina. Pedicel long with short rounded apically process on the side of subapical flagellum. Compound eyes large supported by callus. Postclypeus convex wider than long. Anteclypes short tubular. Rostrum long, second segment more than 1/3 length of third segment. Coryphe twice as wide as long medially deeply grooved. Pronotum wider than coryphe, anterior margin slightly convex, posterior margin nearly straight. Mesonotum nearly as long as pronotum. Forewing short reaching tergite four. Abdomen in lateral view medially concave and posteriorly raised. Legs long, one lateral spine situated in lower third basally on hind tibia. Apex of tibia with five spines. Metatarsomeres I and II with two lateroapical spines, tarsomere II is half the length of tarsomere I. Metatibiotarsal formula: 5/2/2.

Male genitalia ( Figs 5–10 ). Pygofer with straight margins (in lateral view). Anal tube in lateral view long, narrowing apically. Phallobase in lateral view enlarged anteriorly, dorsal lobe concave beneath the aedeagal hooks. Genital styles posteriorly convex apically with long narrow capitulum.

Etymology. This new genus name is a combination of “Formica” for its ant shaped body with the French word “belle”, meaning -beautiful; as the type location is famous for its natural beauty. Gender: masculine.
