Kodaianella longispina Zhang & Chen , sp. nov.

( Figs 19–27 )

Description. Body length (from apex of vertex to tip of forewings): 3 4.4–4.6 mm, Ƥ 5.1–5.3 mm; forewing length: 3 3.5–3.6 mm, Ƥ 4.1–4.3 mm

Coloration. Vertex ( Fig. 19 ) brown with pale brown stripe in midline and two oval dark brown marks near posterior margin. Eyes brown. Frons ( Fig. 20 ) dark brown, with pale brown verrucae near lateral margin. Clypeus brown with dark brown stripes. Rostrum brown. Antenna dark brown. Pro- and mesonotum ( Fig. 19 ) brown, with scattered dark brown spots. Forewings brown with dark brown marks, hind wings dark brown. Legs brown with dark brown stripes or spots. Abdomen ventrally brown.

Head and thorax. Vertex ( Fig. 19 ) pentagonal, 1.7 times wider than long in midline. Frons ( Fig. 20 ) with median carina, 1.5 times wider than long in midline. Pronotum ( Fig. 19 ) without median carina, with small pit beyond each side of middle line. Scutellum ( Fig. 19 ) with weak median carina, tumid in middle. Forewing ( Fig. 21 ) 2.4 times longer than widest part, broadening distally, costal margin convex, apical margin convextruncate, Sc and R convergent near base, each reaching to margin. M bifurcate 1/3 near base, MA bifurcate 1/ 3 near apex, MP simple, Cu bifurcate in distal part, subapical margin veins distinct. Hind wings ( Fig. 22 ) trilobed, veins simple. Hind tibiae with two teeth near apex. Spinal formula of hind leg 10–10–2.

Male genitalia. Anal segment ( Fig. 24 ) in dorsal view subtriangular, 2.5 times longer than widest part, slightly expanding distally, apical margin concave in middle, lateral margins concave near middle, anal foramen near base. Pygofer ( Fig. 23 ) in lateral view, front and hind margins concave in middle. Aedeagus ( Figs 25, 26 ) shallowly U-shaped in lateral view, dorsal lobe apically with median process and lateral lobes apically reflexed; pair of long spines (about 3.8 times longer than median process of dorsal lobe), tapering apically, directed cephalad. Phallus with pair of long stout hooks arising in distal half, acutely tapering apically, directed ventrocephalad below aedeagus. Apical margin of ventral lobe concave in middle. Genital styles ( Fig. 27 ) in lateral view boot-shaped, with obtusely convex in lateral margin.

Type material. Holotype: 3, Dali, Yunnan Province, China, 4 Aug. 2006, Z.-G. Zhang. Paratypes: 4 3, 7 Ƥ, Baoshan, Yunnan Province, China, 8–20 Aug. 2006, P. Zhang, Z.-G. Zhang and Q.-Z. Song; 2 3, 3 Ƥ, Gaoligong Mountain, Yunnan Province, China, 28 May 2009, Z.-H. Yang ( IEGU).

Etymology. The specific name refers to the aedeagus apically with a pair of long spines.

Host plant. Unknown.

Distribution. China (Yunnan) ( Fig. 28 ).

Remarks. This new species is similar to K. bicinctifrons Fennah, 1956 and K. macheta sp. nov. in external morphology, but differs in: (i) vertex 1.7 times wider than long (1.9 times in K. bicinctifrons ; 2.3 times in K. macheta ); (ii) anal segment ( Fig. 24 ) in dorsal view subtriangular, 2.5 times longer than widest part, slightly expanding distally, apical margin concave in middle, lateral margins concave near middle (anal segment oval in K. macheta ); (iii) aedeagus ( Figs 25, 26 ) in lateral view, dorsal lobe apically with a median process and lateral lobes apically reflexed, a pair of long spines (about 3.8 times longer than median process of dorsal lobe), tapering apically, directed cephalad (the apical spines of lateral lobes of aedeagus about 1.0 times longer than median process of dorsal lobe in K. bicinctifrons ); (iv) spinal formula of hind leg 10–10–2 (9–11– 2 in K. bicinctifrons ; 12–10– 2 in K. macheta ).
