Amphinemura tamdao sp. n.

( Figs. 21-23 )

Material examined. Holotype ♂ from Vietnam, Vinh Phu , Tam Dao, 1000 m, 10-16 November 1990, Narčuk ( PMSL).

Adult habitus. General color brown, head dark brown, palpi and legs pale. Pronotum uniformly brown with obscure rugosities.

Male. Forewing length 6.5 mm. Epiproct bearing a long, slender, apically acute and trifurcate median lobe and a pair of short, apically spinous lateral lobes which reach slightly beyond midlength of the median lobe ( Fig. 21 ); lateral aspect of epiproct without visible spines on ventral sclerite ( Fig. 23 ). Mesal paraproct lobe with an apical, more or less linear cluster of stout spines ( Fig. 22 ). Tergum 10 with a few scattered, short sensilla and tergum 9 with a small cluster of sensilla and long setae along posterior margin.

Female. Unknown.

Larva. Unknown.

Etymology. The species name, used as a noun in apposition, is based on the type locality.

Diagnosis. The epiproct of Amphinemura tamdao does not appear to be similar to other regional species. The combination of a long, apically pointed mesal lobe and a pair of short, apically armed lateral lobes of the epiproct is apparently unique to this species.
