Chinese common name. Dzẹãø.

Material examined. CHINA: Yunnan: 1 male, Xishuangbanna Prefecture, Jinghong county, light-trapped, 19 September 1979, Huanguang Zou leg. (NKUM).

Diagnosis. Body size relatively small, dorsum with short, recumbent setae ( Fig. 8a View FIGURE 8 ). Head short and wide, antennomeres relatively short, antennomeres II, III and IV subequal in length; mandibular plates black, transverse swelling pale-yellowish, distinctly elevated, maxillary plates and anteclypeus pale-yellowish, gular lobe with yellowish apex, labrum yellowish, labiomeres III+IV yellowish; preocellar spot relatively small, nearly circular. Pronotum short and wide, lateral margin shallowly convex; exocorium mainly pale, endocorium dark-brown, with 6 pale spots (3+3) aligning in “U” shape, apex of clavus with a pale spot, membrane mainly pale, with pale-brown veins ( Fig. 8a View FIGURE 8 ); legs mainly pale-yellowish. Male paramere relatively short and stout, dorsal side with long setae, processus sensualis small and blunt, with a small tuft of short setae ( Fig. 8b View FIGURE 8 ); parandria with acuminate apex ( Fig. 8c View FIGURE 8 ). Female specimen not examined.

Comparative notes. Saldula niveolimbata can be distinguished from all other species occurring in China by its relatively small body size and the acuminate apex of the male parandria. Lindskog (1995) noted that S. niveolimbata does not fit into Saldula (s.str.) as defined by Lindskog and Polhemus (1992) for lack of the synapomorphic characters of Saldula (s.str.) (i.e., eye spot on median cell of endocorium and laminar projection on the male median endosomal sclerite).

Habitats. The specimen collected from Yunnan was captured by light trapping. Moreover, Kment & Carapezza (2022) recorded the habitat of S. niveolimbata from Socotra, which occurs in the mountainous area with miniature pools or brooks.

Distribution in China. Yunnan (Chen 1987, Chen & Lindskog 1994, Vinokurov et al. 2018)

General distribution. Saldula niveolimbata was originally described from Senegal ( Reuter 1900), with further records from other African countries and the adjacent islands as well as in Oriental and Australian regions (Chen 1987; Schuh et al. 1987; Polhemus & Polhemus 1999, 2012; Kment & Carapezza 2022).
