Liu, Zhi-Qi, Yang, Chi-Kun & Shen, Zuo-Rui, 2004, A Study Of The Genus Heteroconis Enderlein (Insecta: Neuroptera: Coniopterygidae) With Four New Species From Mainland China, Raffles Bulletin of Zoology 52 (2), pp. 365-372 : 370-371

Heteroconis unicornis , new species

( Figs. 14-17 )

Material examined. - Holotype – male ( CAU), Pingxiang, Guangxi Province, South China, coll. C.-K. Yang, 17 May.1963.

Allotype – female ( CAU), Ruili, Yunnan Province, South China, coll. C.-K. Yang, 4 May.1981.

Paratypes – 6 females (5 females, CAU, 1 female, ZRC) same data as allotype .

Description. – Head brown. Eyes black. Frons of male with one piliferous horn-like projection between antennae ( Fig. 14 ), which as long as scape and ampliate distally. Three or four basal segments of antennae whitish, the others dark brown. Scape about three times as long as broad, and no dorsal groove present. Pedicel two and a half times as long as broad. Four basal segments of maxillar palpi brown, their distal segments and entire labial palpi light brown.

Thorax pale brown with dark shoulder spots. Abdomen yellowish brown Male genitalia in ventral view ( Fig. 15 ): Ninth sternite slender and arched, ventral process long tubular, slightly dilated distally. Styli digitiform and a small projection covered hairs present at the base of each stylus. The foliiform structure between styli and basal dorsal apodemes of penis seem to be hypandrium. Penis with two dorsal apodemes.

Female genitalia ( Figs. 16, 17 ): The gonapophysis lateralis fused into a single plate and with dense hairs. Ductus receptaculi strongly sclerotized.

Etymology. – The specific name refers to the projection between antennae.

Remarks. – Though the only male specimen is mounted on microscope slide so that only ventral view can be viewed, it can be easily distinguished from the above species from China, having the ninth sternite, ventral process of male genitalia and ductus receptaculi of female genitalia of normal length. It differs from other species in the genus by the following characters: one horn-like projection as long as scape between antennae in male; three or four basal and the last distal segments of antennae whitish, the others dark brown; male genitalia, ventral process slender, tubular, and slightly dilated distally, styli digitiform in ventral view.

Distribution. – Guangxi and Yunnnan, South China.
