Epacanthaclisis victor Badano, Zheng & Liu sp. nov.

( Figs. 2E View FIGURE 2 , 3B View FIGURE 3 , 13 View FIGURE 13 , 18E View FIGURE 18 )

Diagnosis. Adult: Vertex dark brown with suffused darker markings, anterior margin brown. Pronotum dark brown, with a median faded pale stripe; laterally with a pair of pale stripes; lateral margin black. Mesoprescutum dark brown. Wings apically pointed. Forewing rhegma as a brown stripe; markings on cubital area brown. Male abdomen mostly light brown; tergum 4 anterior and posterior margins generally pale brown; tergum 5 anteriorly paler anteriorly ( Fig. 13A View FIGURE 13 ). Thicker external part of male gonocoxites 9 thrice as wide as internal part; gonocoxites 9 protruded in lateral view, concave; gonostyli 11 slender in caudal view. Male ectoproct not expanded, rounded in lateral view.

Description of adult. Size. Head width: 3.05 mm; forewing length: 32.5 mm; hindwing length: 30.3 mm.

Head. Vertex dark brown with suffused paler areas, anterior margin black ( Figs. 13C View FIGURE 13 ). Scape and pedicel ventrally light brown, darker dorsally; flagellomeres dark brown, paler near torulus. Frons black with a median subtriangular brown marking ( Fig. 13B View FIGURE 13 ). Clypeus yellowish-brown, covered with dark and pale setae. Labrum yellowish-brown. Maxillary palpus light brown, each segment externally with a pale brownish marking. Labial palpus light brown; distal segment fusiform and darker. Mandibles yellowish-brown darker apically.

Thorax. Pronotum dark brown, with median paler stripe; laterally with a pair of short paler lines; lateral margin paler, with many pale hairs. Mesoprescutum blackish; mesonotum blackish. Metanotum and metascutellum black, sclerite margins slightly paler ( Figs. 13C View FIGURE 13 , 7 View FIGURE 7 ). Pleurae dark brown.

Legs. Densely covered with pale and dark setae. Coxae pale yellowish-brown. Tibial spurs brown, barely curved. All tarsomeres blackish; pretarsal claws slightly curved, protruded basally. Foreleg: Femur pale yellowish-brown, dorsally dark brown; tibia dark brown; tibial spur reaching tip of tarsomere 3. Midleg: similar to foreleg. Hind leg: Femur pale brown at base, distally dark brown; tibia dark brown; tibial spur reaching base of tarsomere 2; tarsomere 1 longer than that of fore- and midleg ( Fig. 13A View FIGURE 13 ).

Wings. Membrane largely hyaline, elongate. Forewing longer than hindwing. Pterostigma pale, proximally darker. Rhegma as short indistinct oblique brownish stripe; markings on cubital area indistinct; most crossveins of costal area connected by oblique veinlets, except basal ones; presectoral area with ca. five crossveins, of which the proximal ones connected by oblique veinlets; RP with ten branches; RP origin basal to MP fork, aligned at CuA fork. Hindwing rhegma absent; presectoral area with two crossveins ( Figs. 3 View FIGURE 3 , 13A View FIGURE 13 ).

Abdomen. Male abdomen mostly brown; tergum 4 anterior and posterior margins pale yellow, medially with a pair of short stout tufts of bristles ( Fig. 18E View FIGURE 18 ); tergum 5 not swollen (probably the condition of specimen), anteriorly pale yellow ( Fig. 2E View FIGURE 2 ). Male genitalia. Sternum 9 triangular in ventral view, distal part with long setae ( Fig. 13E View FIGURE 13 ). Gonocoxites 9 shaped as a pair of plates in ventral view, laterally prominent; thicker part of male external gonocoxites 9 thrice as wide as the internal part; internal gonocoxites 9 posteriorly concave. Gonocoxites 11 arched; gonostyli 11 slender in caudal view ( Figs. 13H–L View FIGURE 13 ). Ectoproct rounded in lateral view, ventrodistally with long setae ( Figs. 13D–E View FIGURE 13 ).

Type material. Holotype ♂, CHINA: Xizang, Shigatse, Dinggye County [ḮÜ县], Zhentang Town [Ḝ塘县], VIII.2013 ( MSNG).

Distribution. China (Xizang).

Etymology. This new species is named after the late antlion specialist Viktor Krivokhatsky, author of the first taxonomic revision of the genus Epacanthaclisis ( Krivokhatsky, 1998) . The specific epithet, a noun, has a slightly altered spelling to respect the double meaning of word, i.e., “victorious” in Latin.

Remarks. E. victor sp. nov. differs from the other members of the E. continentalis group in the pronotum dark with faint paler markings not reaching anterior and lateral margin and the wide gonocoxites 9. Whose external part is thrice as wide as the internal one.
