( Figs 12 View FIGURE 12 , 78 View FIGURE 78 )

Diagnosis. This species is characterized by the presence of the gena marked with black spots, the antennae without stripes, the small pale spots on the anterolateral angle of pronotum, the large black spots on the anterolateral angle of mesoscutum, the forewing with brown shadings on pterostigma, the basal crossvein of inner gradate series and CuP, the quadrate cell im, the male entoprocessus curved in dorsal view, the broad and projected apex of entoprocessus, and the deeply bilobed female subgenitale.

Description. Male. Body length 6.9–7.5 mm, forewing length 9.6–10.5 mm, hindwing length 8.8–9.6 mm.

Head narrow, vertex raised. Compound eyes black. Scape and pedicel without stripes. Clypeal margin with brown stripes. Gena marked black spots. Maxillary and labial palpi brownish yellow.

Pronotum with small brown spots on anterolateral angle. Mesoscutum with lager black spots on anterolateral angle. Metanotum without markings.

Legs with dense setae. Pro- and mesotibia with median black spot. Pretarsal claws brown, with basal dilation.

Forewing broad, with distinct brown shadings on pterostigma, basal crossvein of inner gradate series and CuP. Costal area broad basally, with 20–23 crossveins; 10 radial crossveins present. m1 smaller than m2, im quadrate; 7 psm-psc crossveins with pale brown shadings. c1 smaller than c2, dcc opened. A1 forked, A2 and A3 simple. Gradate series with pale brown shadings, inner gradate series with 5–6 crossveins, outer gradate series with 7 crossveins. Faint shadings on forking marginal veins.

Hindwing narrow. Pterostigma short and brown. Costal area with 15–17 crossveins; 7–8 radial crossveins and 6 psm-psc crossveins present. A1 forked, A2 and A3 simple. Gradate series brown, inner gradate series with 4 crossveins, outer gradate series with 5 crossveins.

Abdomen with dense short setae. Tergum VII and sternum VII subquadrate in lateral view; tergum VIII shorter than tergum VII; sternum VIII fused with sternum IX; tergum IX fused with ectoproct. Callus cerci ovoid. Gonarcus arcuate, lateral arms narrow at base and wide at tip; entoprocessus curved in dorsal view, attached at about basal 1/3 of gonarcus, broad and projected at tip; pseudopenis widest near tip.

Female. Body length 7.6–8.1 mm, forewing length 10.2–12.0 mm, hindwing length 9.2–11.0 mm.

Sternum VII longer than tergum VII; tergum VII subquadrate in lateral view and longer than tergum VIII; tergum IX fused with ectoproct. Callus cerci ovoid. Subgenitale bilobed apically; spermatheca thick; vela and ventral impression absent; duct long and coiled.

Type material. Holotype ♂, China, Hainan, Dongfang, Datian National Nature Reserve , 30 m, Yuchen Zheng & Ying Yang ( CAU) . Paratypes: 2♂ 5♀, same as holotype ( CAU) .

Etymology. The scientific name is from Hainan, the locality of the holotype.

Distribution. China (Hainan).

Remarks. This species is similar to A. octopunctata candida , especially in the wing markings. However, this species has no stripes or spots on the outer side of the scape, below the antennae or on the metanotum, and it has large black spots on the anterolateral angle of mesoscutum. Ankylopteryx octopunctata candida has a brown stripe on the scape, and the mesonotum is covered by brown markings or has small brown spots on the mesoscutum and metascutum. The male entoprocessus of this new species is more curved than those of the latter.
