Hahnia flagellifera Zhu, Chen & Sha, 1989

Figs 6–9

Hahnia flagellifera Zhu et al. 1989: 148 , figs 1 – 6 (Holotype female, allotype male and paratype female from rice field, Emei, Sichuan Province, China, August 1980, deposited in Jilin Unversity, not examined); Chen & Gao 1990: 119, figs 149a – f. Song et al. 1999: 361, figs 210I – J, 211J – K.

Material examined. 2 males: China, Yunnan Province, Xishuangbanna Dai Autonomous Prefecture, Mengla County, Menglun Town (active searching), 5 – 12 October 2006, G. Zheng leg.; 1 male: Menglun Town (active searching), 5 – 12 November 2006, G. Zheng leg.; 63 females: Menglun Town (active searching), October 2006 – April 2007, G. Zheng leg.

Diagnosis. Females of this species are similar to those of H. maginii Brignoli, 1977 (female holotype from Italy, deposited in Museo Civico di Storia Naturale, Verona, Italy, examined) in having a single atrium and small sub-spermathecae, but differing from the latter by the large epigynal atrium ( Figs 7 A, 7C, 9D–E) and the widely separated sub-spermathecae ( Figs 7 B, 7D, 9F–G). This species is also similar to H. submaginii sp. nov. ( Figs 17– 20 ) in having similar RTA, embolus, median apophysis and cymbial furrow, but males can be distinguished by the single palpal patellar apophysis ( Figs 6 A–C, 8G–I) (bifid in H. submaginii ), females by the anterior margin of the epigynal atrium arc-shaped or somewhat protruding in dorsal view and the relatively small sub-spermathecae with wide distance from each other ( Figs 7 B, 7D, 9F–G).

Redescription. Male. Total length 2.40 – 2.60. One of them ( Figs 8 A–F) total length 2.49. Prosoma 1.28 long, 0.95 wide; opisthosoma 1.32 long, 0.93 wide. Chelicerae with conspicuous stridulatory files on the lateral surface, 3 promarginal and 6 – 8 retromarginal teeth. Leg formula: 1423. Opisthosoma with some black spots and 4 pale chevron-like marings dorsally. Spiracle located centrally.

Male palpal patellar apophysis recurved and hook-like. RTA long. Embolus originating retro-basally and spiraling clockwise along the margin of tegulum nearly 360º (left palp). Median apophysis membranous, originating retrolaterally. Cymbium furrow deep, which length is almost equal to half of cymbial length ( Figs 6 A–C, 8G–I).

Female. Total length 2.80 – 3.20. One female ( Figs 9 A–C): total length 2.87. Prosoma 1.27 long, 0.97 wide; opisthosoma 1.70 long, 1.37 wide. Leg formula: 4123. Chelicerae with 6 retromarginal teeth. Stridulatory file absent. Other characters as in male.

Epigyne with large, posteriorly extended atrium. Copulatory ducts relatively short, bifurcate in front of atrium. Sub-spermathecae ball-like or tuberculate. Spermathecae located posteriorly, separated by large atrium. Fertilization ducts small, pointing laterally. A pair of hoods found posterior of epigastric furrow, distance of which is wider than width of spermathecae ( Figs 7 A–D, 9G–I).

Distribution. China (Sichuan, Yunnan).

Biology. All male and most of female specimens of H. flagellifera were collected from Rubber-Tea and Paramichelia baillonii -plantations near the Menglun Nature Reserve.

Remark. There are two pairs of receptacula located on the vulva dorsally, which were named basal and second receptacula by Forster (1970) or primary and secondary receptacula by Bosmans and Thijs (1980). Here the basal or primary receptacula connecting with fertilization ducts are named spermathecae, which might be homologue to those of other spider groups. And the second or secondary receptacula are named sub-spermathecae, which are present only in a few other groups, such as Clubiona (Clubionidae) .
