Diagnosis.

Head with projections; basal eight flagellomeres pale; sternite 9 with ventral projection.

Holotype.

Male, China, Yunnan Province, Ruili County, Ruili Botanical Garden, 24.0723°N, 97.8174°E, 29.iii.2019, leg. Yaru Zhao.

Description.

Male. Head (Fig. 5a, b ). Fuscous. Frons with a pair of lateral knobs above antennae and a median projection between antennae. Eyes dark. Antennae 18-segmented. Basal eight and apical two flagellomeres whitish, the others dark brown. Both third and fourth flagellomeres with a short spine. Scape about 3-times as long as broad. Pedicel 2-times as long as broad. Four basal segments of maxillary palp dark brown, apical palpomere whitish. Labial palps dark brown.

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

Wings (Fig. 5c, d ). Fore wing membrane light grayish-brown. Forewing length 2.7 mm, width 1.2 mm. Hind wing almost hyaline. Hindwing length 2.2 mm, width 0.8 mm.

Terminalia (Fig. 6a-d ). Sclerotized. Sternite 9 with a very long and slender ventral projection. Hypandrium absent, or probably fused with segment 9. Gonocoxite-stylus complex with long hairs on inner surface, caudal ending with long hairs on prominent bases. Stylus about 3-times as long as broad in lateral view, with short and thick spines on distal third. Sternite 10 elongated, slightly sinuous in lateral view, caudal part lyriform in dorsal view. Basal apodeme of penis moderately developed, dorso-lateral projection rather small. Tube of penis rather thick between the basal and dorso-lateral projections, distal part slender, directed downwards and forwards.

Female. unknown.

Distribution.

China (Yunnan).

Remarks.

The new species belongs to the Heteroconis terminalis group sensu Sziráki (2005). The male genitalia suggest a relationship with Heteroconis terminalis . However, the new species is characterized by the presence of a median projection on the male frons between the antennae, which is absent in H. terminalis . The two apical flagellomeres are whitish in the new species, whereas only the apical one is whitish in H. terminalis . Stylus about 3-times as long as wide in the new species, about 5-times as long as wide in H. terminalis . Heteroconis yunnanensis sp. nov. is distinguished by having the last two flagellomeres whitish, by the presence of a median projection between the antennae, by flagellomeres 3 and 4 with a short spine, and by stylus about 3 times as long as wide in lateral view.

Etymology.

The new species is named after its type locality.
