Diagnosis.

Head projections absent; basal five or six flagellomeres pale; sternite 9 without a ventral projection.

Holotype.

Male, China, Yunnan Province, Jinghong City, Xishuangbanna Tropical Rainforest National Park, 22.0320°N, 100.8874°E, 25.iii.2019, leg. Yaru Zhao & Mingming Zou. Paratypes. 8 males, same data as holotype.

Description.

Male. Head (Fig. 1a ). Fuscous. Frons without projections. Eyes dark. Antennae 18-segmented. Basal six or seven as well as, eleventh and twelfth flagellomeres whitish, the others dark brown. Scape about 3-times as long as broad. Pedicel 2-times as long as broad. Maxillary and labial palps dark brown.

Thorax. Fuscous, but thoracic sutures, apodemes, meso- and metanotum dorsal spots dark. Legs yellowish-brown.

Wings (Fig. 1b-c ). Fore wing membrane light grayish-brown. Basal cross veins RP-M and M-CuA meeting vein M between the median thickenings. Forewing length 2.8-3.1 mm, width 1.0-1.3 mm. Hind wing almost hyaline. Hindwing length 2.0-2.3 mm, width 0.8-1.1 mm.

Terminalia (Fig. 2a-d ). Strongly sclerotized. Sternite 9 moderately narrow, without a ventral projection. Hypandrium absent, or probably fused with segment 9. Gonocoxites proximally wide, distally pointed and hooked. Stylus large and wide, median part hollow and connected to gonocoxites, caudal lobe with long inner setae (Fig. 2d ). Distal part of penis curving upwards and forwards, then directed downwards.

Female. unknown.

Distribution.

China (Yunnan).

Remarks.

The new species belongs to the Heteroconis terminalis group sensu Sziráki (2005). Heteroconis orbicularis sp. nov. appears close to Heteroconis helenae Sziráki, 2001 and Heteroconis sakaeratica Sziráki, 2002, based on the similarities of the male terminalia. However, there is no hypandrium in the new species. Moreover, flagellomeres 11-15 are brown in H. helenae and H. sakaeratica , whereas they are whitish in the new species. Furthermore, the penis of the new species is characterized by a dorsal projection on the apical part, absent in H. helenae and H. sakaeratica . Heteroconis orbicularis is distinguished by having its last two flagellomeres dark, by the absence of a hypandrium and a ventral projection on the 9th sternite, by basal lobes of styli not connected, by distal part of penis forming a circle, and by dorsal projection of penis very long and slender.

Etymology.

The new species is named after its penis shape.
