Abstract

Meotipa lingchuanensis (Zhu & Zhang, 1992) comb. nov. Figs 6, 7 B, C, F, G, J, K Chrysso lingchuanensis: Zhu and Zhang 1992: 22, fig. 2 A – D (female); Zhu 1998: 55, fig. 29 A – F (male, female); Song et al. 1999: 103, fig. 49 E, F, M, N (male, female); Lin et al. 2023: 521 (synonym of Chr. hyoshidai). Chrysso hyoshidai: Barrion et al. 2013: 34, fig. 38 A – E (female). Material examined. 12 males, 19 females (PWFJ 2024016 –2024046): China – Fujian Province • Zhangzhou City, Zhangpu County, Futouwan; 23.9287°N, 117.6626°E; elev. 20 m; 14 July 2024; H. L. Chen et al. leg. Diagnosis. Meotipa lingchuanensis (Zhu & Zhang, 1992), comb. nov. is similar to Meo. pseudomultuma Liang, Yin & Xu, 2024 (cf. Fig. 6 and figs 3 D – F, 4, 5 D – F, 6 in Liang et al. 2024) in having a pointed conductor tip and laterally situated copulatory ducts, but it can be distinguished from Meo. pseudomultuma by: (1) sperm duct in tegulum strongly curved (vs slightly curved); (2) conductor tip curved in ventral view (vs straight); (3) conductor wide, almost 1 / 2 the width of bulb (vs narrow, almost 1 / 4 the width of bulb); (4) epigynal atrium present (vs absent); and (5) posterior margin of epigyne curved (vs straight). Description. See Zhu (1998). Remarks. This species possesses three pairs of spines on the posterior extension of the dorsal opisthosoma (arrows in Fig. 7 K point to the spine sockets, but the spines are missing; fig. 29 B in Zhu 1998), and the copulatory organs of this species are similar to the generotype (cf. Fig. 6 and figs 8 G – I, 9 C, D in Benjamin and Tharmarajan 2024): i. e. the embolus is surrounded by the conductor. Therefore, we transfer this species to the genus Meotipa. Distribution. China (Fujian, new provincial record; Guangdong; Guangxi; Hainan; Jiangxi).
