sp. nov.

Kakuna zhongtuana sp. nov.

( Figs 23–34 View FIGURES 23 – 34 )

Description. Body length (from apex of vertex to tip of forewings): male 5.55 –6.00 mm (N = 4); female 6.25–6.60 mm (N = 6).

Coloration. General color yellowish brown to brown. Ocelli reddish brown, eyes blackish brown. Rostrum with apex fuscous. Antennae yellowish brown, except apex of basal segment and base of second segment, fuscous. Forewing ( Fig. 25 View FIGURES 23 – 34 ) pale yellowish brown, with a fuscous large, longitudinal band from base of costal area to apex in male, apex of I A with a small blackish brown marking. Thorax with lateral and ventral areas pale brown. Legs yellowish brown, except apex of digitus fuscous. Abdomen brown to fuscous. Color of female paler than male, forewing ( Fig. 26 View FIGURES 23 – 34 ) pale yellowish brown, apical part with a brown, broad, longitudinal band from front of transverse vein to apex.

Head and thorax. Vertex including eyes narrower than pronotum (0.79: 1). Vertex shorter in middle line than wide at base (0.65: 1), broad at apex narrower than at base (0.78: 1). Frons longer in middle line than wide at widest part (about 2.30: 1). Antennae with basal segment 1.85 times as long as broad at apex, shorter than second segment (0.56: 1). Pronotum as long as vertex in middle line. Mesonotum 1.78 times as long as vertex and pronotum together in middle line. Forewings longer in middle line than broad at widest part (3.37– 3.41: 1). Post-tibial spur with about 27 teeth along hind margin. Basal segment of digitus longer than second and third combined (1.70: 1).

Male genitalia. Anal segment of male ( Fig. 28 View FIGURES 23 – 34 ) short, ring-like, almost sunk in the emargination of pygofer, ventral margin without process. Pygofer in profile ( Fig. 29 View FIGURES 23 – 34 ) with dorsal margin shorter than ventral margin, laterodorsal angle strongly produced caudad, posterior margin slightly sinuate; in posterior view ( Fig. 30 View FIGURES 23 – 34 ), with opening longer than wide, ventral margin broadly concave. Suspensorium ring-like. Aedeagus in profile ( Fig. 33 View FIGURES 23 – 34 ) tubular, broadly curving medially, apex rounded; in ventral view ( Fig. 32 View FIGURES 23 – 34 ) with apical half subtriangular, having two rows teeth along lateral margins. Diaphragm ( Fig. 31 View FIGURES 23 – 34 ) with dorsal margin broadly produced dorsad, median part with two spine-like processes, which having a long common stalk basally. Genital style in profile ( Fig. 34 View FIGURES 23 – 34 ) broad at base, narrowing apically, apex acute, inner margin with a nipple-like process at middle.

Type material. Holotype: 3, China: Guizhou, Leishan, Leigongshan National Natural Reserve (26 o 28 ′N, 108 o 17 ′E), 1900 m, 2 Aug. 2004, D.-Y. Ge and P. Xu; paratypes: 1 3, 5 Ƥ, same data as holotype; 1 3, 1 Ƥ, Guizhou, Suiyang, Kuankuoshui National Natural Reserve (27 o 58 ′N, 107 o 11 ′E), 4 Aug. 1984, Z.-Z Li; Guizhou, Daozhen, Dashahe Provincial Natural Reserve (28 ° 53´N, 107 ° 36´E), 1400 m, 17 Aug. 2004, X.-S. Chen; 1 3, Guizhou, Libo, Maolan National Natural Reserve (25 ° 40´N, 108 °05´E), 600 m, 4 Aug. 2006, F.-L. Xu.

Host plant. Bamboo [ Qiongzhuea communis Hsueh & Yi and Sinobambusa kunishii (Hayata) Naki ].

Distribution. Southwest China (Guizhou: Leishan, Suiyang, Daozhen, Libo) ( Fig. 35 View FIGURE 35 ).

Remarks. This new species is similar to K. kuwayamai and K. nonspina , but can be distinguished by: i) body color paler, forewing with the marking of apex of IA unclear; ii) anal segment without process; iii) aedeagus with two rows teeth along lateral margin of apical half; iv) two processes of diaphragm with a long common stalk; v) genital style with a nipple-like process at middle of inner margin.

Etymology. The name is derived from transliteration of the Chinese “zhongtu”, meaning genital style having a nipple-like process at middle of inner margin.
