Balta jinlinorum Che and Wang sp. nov.

Figures 57–67

Description. Pronotum length×width 2.3–2.8× 3.4–4.6 mm; tegmen 11.0–13.0 mm; overall length including tegmen 13.0–15.0mm. Body yellowish brown. Vertex pale yellow or yellowish white. Discoidal area of pronotum yellowish brown with black spots, broad lateral areas semihyaline. Venter yellowish brown, lateral area with dark brown stripes and spots.

Vertex with interocular space slightly less than distance between antennal sockets (Fig. 57). Third and fourth maxillary palpomeres about same length, both distinctly longer than the fifth. Tegmen with discoidal veins longitudinal. Hind wing with most costal veins bifurcated; medial vein simple, without branches; cubital vein with 4 complete branches and 1 incomplete branch, triangular apical area reduced and small (Fig. 59). Front femur of Type B2 (Fig. 60), tarsal claws strongly asymmetrical and unspecialized (Fig. 61). Male genitalia with supra-anal plate in ventral view short, hind margin smoothly arched (Fig. 62); right and left paraprocts slightly symmetrical, plate simple, distorted, with apices rounded and with scattered short setae (Fig. 62). Subgenital plate in dorsal view with lateral margins strongly curved, hind margin deeply and concavely excavated with large quadrangular, semihyaline medial lobe; styli fingerlike, arising on each side of excavation and directed medially (Fig. 63). Left phallomere enlarged, sclerotized plates irregular (Fig. 64). Median phallomere long, sticklike, slightly curved with base blunt and apex acuminate (Fig. 65); one associated median phallomere appendage present, which is bifurcated near middle and with apex swollen into long brush-like structure, the branch beneath arched and apex tapering, the other below bent in the middle, twining with basal part of median phallomere, apex blunt (Fig. 66). Hook-like phallomere with sclerotized portion small, on right side, slender and with V-shaped preapical incision (Fig. 67).

Material examined. Holotype m?, China, Fujian, Cong’an, 230–250m, 26 May 1960, Jin Gentao and Lin Yangming coll. Paratypes: 1m?, Hainan, Jianfeng Mountain, 14 May 1997, Wang Lianmin coll.; 2m?, Guangxi, Longzhou, 31 May 1997, Yang Maofa coll.; 1m?, Anhui, Huoshan, Fozi Mountain, 200m, 6 July 1964, Jin Gentao coll.; 1m?, Jiangxi, Jiulian Mountain, 3 May 1986, Luo Zhiyi coll.; 2m?, Guizhou, Leigong Mountain, Xiaodanjiang, 800–900m, 5 June 2005, Tang Yi coll.; 1f?, same data but Song Yuehua coll.

Remarks. This species resembles B. barbellata Che & Chen sp. nov., but it can be distinguished from the latter by the following characters: 1) front femur of Type B2 (B 3 in barbellata); 2) median phallomere with only one large brush-shaped appendage near distal portion (two small brush-shaped appendages either near distal portion or at base in barbellata); 3) middle of hind margin of subgenital plate nearly truncate and not produced in dorsal view (produced and rounded in barbellata).

Etymology. The specific name is the combination of the family names of the holotype collectors (Jin Gentao and Lin Yangming).
