Yuanamia gen. nov.

Type species: Yuanamia anastoma, Zhang and Duan sp. nov.

Stramineous to ochraceous. Vertex and pronotum with brown longitudinal bands.

Vertex with fore margin acutely rounded, coronal suture long. Forewing with four apical and three anteapical cells, claval veins joined by cross veins, appendix present.

Male genitalia: Pygofer short, without processes, with numerous macrosetae in posteroventral region. Valve and subgenital plates fused, subgenital plate with a uniseriate row of marginal macrosetae. Style with long articulatory arm, preapical lobe angled, apical process digitate. Connective linear, fused to aedeagus. Aedeagal shaft elongate, slender, apex forked in dorsal aspect.

Remarks

This genus is similar to Peitouellus Vilbaste (1969) and Miradeltophus Dash & Viraktamath (1995) in having a fused valve and subgenital plates and very elongate aedeagal shaft. It differs from the former in lacking an articulated apical section of the aedeagal shaft, and from the latter in having bifurcate apex rather than two apical aedeagal processes.

Etymology

The generic name is to be treated as an arbitrary combination of letters; gender feminine.
