Etymology. The name is a combination of Hukawng, as a reference to the Hukawng Valley where Kachin amber is widely found, and Epyris , the type genus of the Epyrinae . Gender masculine.

Type species. Hukawngepyris setosus sp. nov., by monotypy.

Diagnosis. Females of the new genus stand out of all known bethylid genera by the following combination of characters: Vertex, gena, pronotum, mesopleuron, and mesoscutellum foveolate; head and anterior mesosoma with scattered long erect setae ( Figures 2 and 3A ); compound eyes without setation, 0.6 × HL; malar space convergent, longer than VOL; median clypeal lobe triangular, projecting; mandible elongate, quadridentate; antenna filiform ( Figure 3B ); scape and pedicel bearing long thick setae; pedicel shorter than each of the flagellomeres; anterior ocellus crossing supra-ocular line; distance between anterior and posterior ocelli shorter than width of ocellar triangle; occipital carina complete. Pronotum longer than wide, with anterior angle rounded; without longitudinal sulcus ( Figure 3B ); notaulus and parapsidal signum present; sulcus of the mesoscuto-mesoscutellar suture present; mesoscutellum not contacting metapectal–propodeal complex ( Figure 3C ); metapostnotal median carina complete, straight, extending on propodeal declivity ( Figure 4A ). Forewing with C, Sc + R, M + Cu, A, Rs&M, cu-a, and 2r-rs&Rs tubular; 2r-rs&Rs tubular and curved, distally reaching anterior wing margin. Hind wing with three straight proximal and three hook-like distal hamuli ( Figures 2 and 4C ). Protibial spur long and stout ( Figure 3C ); tarsal claw bifid ( Figure 4B ). Metasomal tergum 2 entirely smooth ( Figure 4B ).
