( Fig. 7 )

Bittacus longiprocessus Huang & Hua, 2005: 395 . Type locality: Fujian, China.

Diagnosis. Bicaubittacus longiprocessus can be readily separated from its congeners by its gonocoxites, which are not prolonged noticeably backwards from their middle part, and by having the apex of the upper branch of the proctiger rounded, not emarginated into L-shape.

Abdomen of female yellowish brown. Terga III–VII each with a narrow black antecosta; sternum VII trapeziform, anterior margin narrower than the posterior one ( Fig. 7 E). In lateral aspect, subgenital plate narrow basally, gradually broader towards apex; dorsal margin curved smoothly and not deeply emarginate ( Fig. 7 E); in ventral aspect, distal margin narrowly prolonged caudad; the two halves separated to the very apex by a membrane ( Fig. 7 D); membranous area broad basally, subtriangular in shape. Tergum X pale sordid yellow, extending very slightly ventrad; supra- and subanale yellowish brown, truncate apically ( Figs 7 F, G). Cerci short, slightly longer than subanale ( Fig. 7 G).

Material examined: Holotype ɗ, Nanjing, Fujian Province, 9.V.1995, coll. Jiang Fan [ NWAU]. 1ɗ1Ψ, CHINA: JIANGXI: Ciping, Mt. Jinggangshan, 15.V.1981, coll. Jin et al., preserved in the Shanghai Entomological Museum, Shanghai [ SHEM].

Distribution. China (Fujian, Jiangxi).

Remarks. This species previously was known only by the male holotype in the original description ( Huang & Hua, 2005). Here we find two additional specimens (one male, one female) from Jiangxi Province. The male genitalia is re-illustrated according to a pinned specimen from Jiangxi ( Figs 7 A–C) for more accuracy. The female is described and illustrated here for the first time.
