description: Ommatissus lateralis sp. nov.
(Figs 4–6, 24–34)
Description. Body length (from apex of vertex to tip of forewings): male 3.9–4.0 mm (N=6), female 4.2–5.0 mm (N=6).
General colour pale yellow, abdomen dark brown. Vertex and pronotum (Fig. 5) pale yellow, mesonotum yellowish brown or dark brownish. Frons (Fig. 6) with dark circular spot in upper part on each side of meidan carina. Postclypeus pale yellow or black brown, anteclypeus stramineous with pale yellow median callus, genae pale yellow, lorae diffusely dark brownish. Forewings (Fig. 4) pale yellow, tips of spines on hind tibiae and tarsi black.
Vertex (Fig. 24) shorter in middle than widest breadth (1.0:1.8). Frons (Fig. 26) longer in middle than widest breadth (1.5:1.0). Pronotum (Fig. 24) broader than long (4.7:1.0). Froewings (Fig. 27) with about five apical cells. Hind tibia with 2 distinct lateral spines, spinal formula of hind leg 7–8–2.
Male genitalia. Pygofer (Fig. 29) symmetrical, anterior margin concave. Anal tube (Figs 32–33) short, anal style not surpassing anal tube. Gonostyli (Figs 29–31) bilaterally symmetrical, in lateral view about 1.5 times as long as broad, basal half narrow and apical half broad, in side view with strong hook-like process arising from laterdorsal margin, acute tip at apex, and small triangular process at base, subapical knife-like process pointed to inside. Aedeagus (Figs 29, 32–34) elongate and tubular; shaft slender in lateral view, base very broad, then becoming narrow, tip nozzle-shaped, with phallotrema apically exposed. Periandrium (Figs 32–34) surrounding aedeagus basedorsally, connected with ventrobasal margin of anal tube, ventral projection well developed, with asymmetrical lobate process, subapical part with one tooth-like process in left side, pointed to outer side, ventral margin with 2 teeth.
Type Material. Holotype ♂, Xishan Park (25°04′N, 102°42′E, 1,950 m), Kunming, Yunnan, China, 30 Aug. 2006, P. Zhang. Paratypes: 7♂♂, 6♀♀, same data as holotype; 1♂, Ceheng County (25°00′N, 105°48′E), Guizhou, 23 Aug. 2008, X.-S. Chen; 1♂, Ceheng County, Guizhou, 26 Aug. 2012, Z.-M. Chang; 1♂, Ailao Mountain National Nature Reserve (24°21′N, 101°10′E), Yunnan 22 Jul. 2012, Z.-M. Chang; 1♂, 4♀♀, Maling River (25°05′N, 104°53′E), Xingyi City, Guizhou, 25 Aug. 2008, X.-S. Chen and L. Yang.
Host plant. Unknown.
Distribution. China (Yunnan, Guizhou).
Etymology. This new species is named for the presence of subapical periandrium with one tooth-like process in left side, pointed to outer side.
Remarks. This species is similar to O. trimaculatus sp. nov., but can be distinguished from the latter by the frons with one dark circular spot in upper part on each side of meidan carina; gonostyli in lateral view about 1.5 times as long as broad, with basal half narrow and apical half broad, and subapical part with knife-like process pointed to inner side.
