Amphinemura auriculata Du & Wang , sp. nov.

( Figs. 1–8 )

Adult habitus. Head brown, antennae pale brown; head wider than pronotum, pronotum brown, paler than head with darker rugosities; wings hyaline, veins brown; legs pale brown.

Male. Forewing length 6.0– 6.2 mm, hind wing length 4.9–5.1 mm. Tergum 9 slightly sclerotized, except posterior margin which is well sclerotized; several long, pale brown spines located on the raised posterior margin. Tergum 10 slightly sclerotized, a membranous area present near middle of anterior margin; several small spines located on each side of a flat slightly sclerotized plate under the epiproct. Hypoproct broad at base, tapering and forming a bluntly rounded apex, covering part of inner lobes of paraprocts; vesicle short, 1.5X long as width. Paraprocts divided into 3 lobes, inner lobe darkly sclerotized apically; median lobe slightly sclerotized, widest at base and narrowed at middle with an ear–shaped projection protruding from the expanded apex; long hairs on the lobe base and on the tip of its ear–shaped projection; outer lobe slender, base sclerotized, and the middle wide and flat, a line of short spines located along the margin of the sickle–shaped apex. Epiproct dorsally 3X longer than wide, tapering to a bilobed at tip; dorsal sclerite lightly sclerotized; lateral arms darkly sclerotized; ventral sclerite thin and long, reaching over dorsal sclerite, forming a thin ridge which bearing two rows of darkly sclerotized spines at 1/3 length from apex.

Female. Unknown.

Type material. Holotype male, CHINA: Futian village, Eryuan county, Yunnan province, 24 May 1996, Leg. Du Yu–Zhou. Paratypes 2 m, same data as the holotype.

Etymology. The name refers to the ear–shaped tip of the median lobes of the paraprocts. The Latin auricula meaning little ear.

Remarks. This new species is similar to Amphinemura multispina Wu, 1973 in having a long, thin epiproct, but the median lobe of the paraprocts of this new species is ear–shaped, while the median lobe of the paraprocts of A. multispina is hammer–shaped and armed with long hairs apically.
