description: <i>Kirbyana spinata</i> sp. nov. (Figs 46‒47) <b>Description.</b> Body length: male 4.8 mm (<i>n</i> = 1). <i>Coloration</i>. General color brown (Fig. 46A–E). Eyes dark brown, ocelli light yellow, semitransparent. Vertex, face, frons, pronotum and mesonotum brown, speckled with small pale spots. Rostrum brown. Forewing semi-translucent; yellowish brown, a large dark brown spot near Cu fork, and small brown spots on the ends of longitudinal veins, stigma yellowish brown. Hind tibiae brown and abdominal sternites dark brown. <i>Head and thorax</i>. Vertex (Figs 46C, 47A) broad, 2.5 times wider than long; anterior margin nearly transverse, posterior margin archedly recessed. Frons (Figs 46D, 47B) widest at the level of antennae, 1.1 times wider than long; frontoclypeal suture nearly concave into an arch; middle carina with basal half absent; lateral carinae distinct and slightly elevated. Pronotum (Figs 46C, 47A) 2.3 times longer than vertex; median carina indistinct, posterior margin nearly at right angle. Mesonotum 1.6 times longer than pronotum and vertex combined. Forewing (Fig. 47C) 2.2 times longer than wide, with 11 apical and 6 subapical cells; fork Sc+RP slightly basad of fork CuA 1 +CuA 2, first crossvein r-m basad of fork MP, RP two branches, MP with five terminals: MP 11, MP 12, MP 2, MP 3, and MP 4, fork MP 1 +MP 2 basad of fork MP 3 +MP 4. Metatibiotarsal formula: 6/9/9, second segment of hind tarsus with 4 platellae. <i>Male genitalia</i>. Pygofer (Fig. 47D, E) symmetrical, dorsal margin concave and U-shaped; in lateral view, lateral lobes trapezoidal, caudally extended, medioventral process round in ventral view. Anal segment (Fig. 47D, F) broad, tubular, dorsal margin almost straight, ventral margin extremely extended, apical lobes round in lateral view; 1.4 times longer than wide in dorsal view; anal style strap-shaped, not beyond anal segment. Gonostyli (Fig. 47D, E, G) symmetrical in ventral view; in inner lateral view, dorsal margin bending inwards in a right angle in the middle, apical part acute. Aedeagus (Fig. 47H–K) with total of five processes. Right apex of periandrium with a long spinous process, slightly curved and right-cephalically directed; the apical 1/3 of the ventral margin with a delicate spinous process, weakly sclerotised, ventrocephalically directed; left side of periandrium with two spinous processes, one originating from basal 1/4, long, slightly curved and ventrocaudally directed, the other one on the apex, slender, slightly curved and ventrocephalically directed. Endosoma (=flagellum) moderately sclerotised, relatively short, generally curved to the right, apex with several spines, a medium-sized straight spinous process on dorsal margin of apex, ventrocephalically directed. <b>Type material.</b> Holotype: &amp;male;, CHINA: Lvchun County (23°0’N, 102°23’E), Yunnan Province, 3 August 2012, leg. Wei-Bin Zheng. <b>Host plant.</b> Unknown. <b>Distribution.</b> China (Yunnan). <b>Remarks.</b> Male genitalia of <i>K. spinata</i> sp. nov. are similar to those of <i>K. pacifica</i> Emeljanov &amp; Hayashi, 2007, but differ in: (1) right base of periandrium without spinous process (right base of periandrium with a long spinous process in <i>K. pacifica</i>); (2) left side of periandrium with one spinous process at each base and apex (the latter without process on left side). <b>Etymology.</b> The specific name refers to the apex of the endosoma with several spines.
