(Figs. 2, 12–21) Description ɗ, length (from apex of vertex to tip of fore wings) 5.9–7.2 mm ; fore wings length: 4.8–5.6 mm . FIGURES 12–16. Zema montana sp. nov. 12. head, pronotum and mesonotum, dorsal view; 13. head, ventral view; 14. head, pronotum and mesonotum, lateral view; 15. right fore wing; 16. right hind wing. General color brown; two patches on disc of vertex and a narrow, longitudinal stripe beyond median carina on pronotum blackish; frontal disc and clypeus largely fuscous; a broad band overlying fronto-clypeal suture ivory-white; clypeus with two, longitudinal piceous stripes beyond median carina; tip of rostrum fuscous; eyes reddish; most of gena ivory-white, with a blackish patch between eye and lateral margin of vertex and a large circular, black patch below eye; antennae with pedicel black, sensory plaque organs white; pronotum with ventral portion of lateral lobes covered with an oblique, blackish stripe, and the marginal portion ivory-white; mesonotum with irregular, blackish stripes, base of mesoscutellum with fuscous suffusion; legs covered with longitudinal, fuscous stripes on femora, tibiae, pro- and mesotarsi; abdominal sclerites blackish; fore wings transparent, veins brown, apex of clavus with blackish suffusion. FIGURES 17–21. Zema montana sp. nov. 17. male genitalia, lateral view; 18. male genitalia, dorsal view; 19. male genitalia, caudal view; 20. anal segment and aedeagus, lateral view; 21. corpus connective and parameres, ventral view. Vertex ( Fig. 12 ) distinctly shorter in midline line than breadth at base (2.14:1). Frons ( Fig. 13 ) longer in middle than the widest breadth (1.44:1), with a broad callus at anterior margin, longitudinal carina, which between middle line and lateral carina, nearly parallel, uniting with median carina in the broad callus. Clypeus ( Figs. 13, 14 ) with thicken median carina. Male genitalia ( Figs. 17–21 ) relatively large, Periandrium ( Figs. 17, 18, 20 ) large and elongate, symmetrical, with its basal half surrounding basal 1/2 of penis; penis slender and elongate, distinctly sinuate, apical half directed posteroventrally in lateral view, apex distinctly forked.

Material examined
Holotype ɗ, CHINA: Yunnan,	Mt.	Meili,	3200	m,	6-VII-2006 (M.	F.	Wang)	(IZCAS). Paratype. 1ɗ,	same
data as holotype (IZCAS).

Etymology
The specific epithet is derived from the Latin	‘ montanus’ ,	mountain,	referring	to	the	specimens of	the
species collected at a high altitude of 3200 m.

Distribution Southwestern China (Yunnan). Remarks This species can be distinguished from Z. gressitti Fennah by the median carina of vertex percurrent (median carina only present in basal two-thirds in Z. gressitti ), periandrium symmetrical (periandrium asymmetrical, denticulate on apical margin in Z. gressitti ), and penis distinctly sinuate, much longer than that of Z. gressitti (about 4:3), apex distinctly forked (penis appreciably sinuate, forming a distinctly fork from middle part in Z. gressitti ).
