Tenguna plurijuga sp. n. Figs 19-32, 33-37

Measurements.

♂, BL: 14.9 mm; HL: 2.1 mm; HW: 1.6 mm; FWL: 11.4 mm. ♀, BL: 15.2-16.7 mm; HL: 2.2-2.5 mm; HW: 1.6-1.8 mm; FWL: 11.6-12.3 mm.

Diagnosis.

This species can be distinguished from other species from aedeagus and phallobase. The aedeagus with pair of unequal long processes apically; phallobase with numerous membranous lobes at apex.

Description.

General color and external characters as the Tenguna kuankuoshuiensis sp. n.

Cephalic process (Figs 19-24) relatively short, a little upturned, ratio length to length of pronotum and mesonotum combined 0.7. Vertex (Figs 19-22, 24) with lateral margins carinate, sub-parallel at base, slightly sinuate in front of eyes, then gradually narrowing to arrowhead at apex, ratio of length to width between eyes 2.3. Frons (Fig. 23) elongate, median carina complete and elevated, length 3.0 times long than width. Pronotum (Figs 21, 24) distinctly shorter than mesonotum medially in the middle line, median carina distinct, lateral carina obscure, ratio length to length approx. 0.2:1. Forewings (Figs 19, 20, 25) with Sc+R, M and Cu all branched apically; stigma distinct, with five cells. Legs narrow and moderately long; fore femur with one minute, short, blunt spine near apex; hind tibia with six lateral black-tipped spines and eight apical black-tipped teeth.

Male genitalia. Pygofer (Figs 27-29) wider ventrally than dorsally, posterior margin with a blunt process, ventral margin depressed to accommodate anal tube. Parameres (Figs 27, 28) large, distinctly broadening towards apex in lateral view (Fig. 27), posterior margin straight, upper margin with dorsally directed, black-tipped process near middle, with ventrally directed, hook-like process near sub-middle on outer upper edge. Anal tube (Figs 27, 29) oval in dorsal view, ratio length to width 2.0:1. Aedeagus (Figs 30-32) with one pair of unequal long processes apically, processes with apex acute, sclerotized and pigmented. Phallobase sclerotized and pigmented at base, with numerous membranous lobes at apex.

Female genitalia. Anal tube (Fig. 34) round and large in dorsal view, ratio of length to width at middle approx. 0.7. First valvula (Fig. 35) sclerotized with seven differently sized teeth in lateral view. Second valvulae (Fig. 36) triangular, symmetrical in ventral view, connected at base and separated from 1/5 base. Third valvula (Fig. 37) with 2 sclerotized lobes, lateral lobe with 4 long spines at apex.

Type material.

Holotype ♂, China, Guizhou, Institute of Entomology. XII. 2008, Light trap, Zhangyubo. Paratypes, 6♀♀, data same as holotype.

Etymology.

This new species is named for the Greek word " plurijuga " referring to aedeagus with numerous membranous lobes at apex.
