Epacanthaclisis hamata Krivokhatsky, 1998: 49 View in CoL (type locality: Kazakhstan: Aksu River (Aksu-Dzhabagly Nature Reserve), Kara-Alma, Tallas Alatoo Mt.; holotype in ZISP). Stange, 2004: 88 ( Epacanthaclisis View in CoL ).

Diagnosis. Adult: Vertex pale brown, anteriorly with a pair of dark spots. Pronotum pale yellowish-brown, anteriorly with a pair of curved transversal dark brown bands, medially with a pair of longitudinal short dark brown stripes, posterolaterally with a pair of indistinct short longitudinal dark brown stripes, and lateral margin with a pair of longitudinal dark brown stripes. Wings generally hyaline. Male abdominal terga 3–5 each medially with a longitudinal dark brown marking, anterolaterally with a pair of dark brown stripes. The strongly sclerotized part of male external gonocoxites 9 as wide as the internal part; gonocoxites 9 protruded in lateral view; gonostyli 11 pointed in ventral view, slender triangular in caudal view. Male ectoproct barely expanded, distal margin truncated in lateral view.

Re-description of the holotype. Size. Head width: 2.54 mm; forewing length: 33.22 mm; hindwing length: 30.68 mm.

Head. Vertex pale brown, anteriorly with a pair of dark spots.A black marking present on the insertion of antenna and anterior frons ( Fig. 10C View FIGURE 10 ). Scape and pedicel pale brown; flagellum generally brown, gradually darkening on distal part. Frons anteriorly with a concave dark marking ( Fig. 10B View FIGURE 10 ). Clypeus and Labrum generally pale yellowish-brown. Maxillary and labial palpi generally pale yellowish-brown. Mandibles yellowish-brown with distal half dark reddish brown.

Thorax. Pale yellowish-brown and dark brown, covered with many pale setae. Pronotum pale yellowish-brown, anteriorly with a pair of curved transversal dark brown bands, medially with a pair of longitudinal short dark brown stripes, posterolaterally with a pair of indistinct short longitudinal dark brown stripes, and lateral margin with a pair of longitudinal dark brown stripes; lateral margin covered with many pale hairs. Mesoprescutum dark brown, with a pair of pale yellowish-brown markings; mesonotum pale yellowish-brown, medially with a pair of slender lines, laterally with a pair of dark brown markings; mesoscutellum pale yellow, anteriorly dark brown in some individuals.
