Pronotum length×width 3× 4.2 mm; tegmen 14.5 mm; overall length including tegmen 17.2 mm. Body pale brown. Vertex brown, occiput region yellowish white; antenna dark brown. Pronotum with discoidal area and anterior margin brown, lateral and posterior margins hyaline ( Fig. 47). Tegmina pale brown with costal areas paler. Venter and legs yellowish brown suffused with brown. Vertex with interocular space slightly less than distance between antennal sockets ( Fig. 46). Fourth and fifth maxillary palpomeres about same length, both distinctly shorter than the third. Pronotum with one irregular macula ( Fig. 47). Tegmen with discoidal veins strongly oblique. Hindwing with costal veins slightly clubbed or thickened; medial vein curved near medial part and without branches; cubital vein with 5 complete branches, two branches bifurcated at apex, triangular apical area reduced and small ( Fig. 48). Front femur of TypeC2 ( Fig. 49), tarsal claws strongly asymmetrical and unspecialized ( Fig. 50). Male genitalia with supraanal plate in ventral view short, with mediodistal region rounded-convex ( Fig.51); right and left paraprocts slightly asymmetrical, plate simple with apices rounded and with numerous setae ( Fig.51). Subgenital plate in dorsal view nearly elliptic, lateral margins smoothly curved, hind margin deeply and concavely excavated with one large projecting medial lobe; styli small and fingerlike, with scattered short setae, located on lateral lobes and directed posteriorly ( Fig. 52). Left phallomere enlarged, sclerotized plates irregular ( Fig. 53). Median phallomere long, sticklike, slightly curved, with base blunt and apex bifurcated ( Fig. 54); one associated median phallomere appendage present and below median phallomere, the upper half nearly S-shaped with apical part slender and acuminate, distal part robust, hind margin serrated, the other half a simple plate but left side irregular ( Fig. 55). Hook-like phallomere with sclerotized portion very small, slender and with V-shaped incision ( Fig. 56).   Material examined. Holotypem?, China, Hainan, Jianfeng Mountain, 26 November 1981, Liang Songzhi coll. Paratypes: 1m?, same data as holotypebut 7 July 1981, Guo Qiuming coll.; 1m?, same data as holotypebut 28 July 1983, Hua Lizhong coll.   Remarks.  Balta curvirostrisis easily differentiated from  B. variegata(Hanitsch, 1933)by the following: 1) pronotum with discoidal area and anterior margin brown, lateral and posterior margins hyaline in  B. curvirostris; pronotal disk shiny reddish brown, lateral margins yellowish, posterior margin dark brown in  B. variegata; 2) supraanal plate in ventral view short, with mediodistal region rounded convex in  B. curvirostris; supraanal plate transverse in  B. variegata; 3) median phallomere long, sticklike, slightly curved with base blunt and apex bifurcated in  B. curvirostris; median phallomere divided on distal half, one branch with setose membrane and long filament directed to left in  B. variegata.   Etymology.The specific name “  curvirostris” is derived from Latin and refers to the distinctly curved, posteriorly directed styli.
