Spinnerets light brown, surrounded by an annular plate. Figure 21. Swilda spinathoraxi A male habitus, dorsal B male habitus, ventral C male habitus, lateral D female habitus, dorsal E female habitus, ventral F female habitus, lateral.

Somatic characters (Fig. 21D-F ). Colouration : prosoma and legs as in male. Abdomen pale dorsally and light grey ventrally. Carapace modified as in male. Cephalic part lower than in male. Legs : the spination same as in male, except tibia II lacking clasping spine. Opisthosoma : globose, with sparse, long setae, without posterolateral scutum. Other modifications same as in male. Epigyne (Fig. 22C-E ): sclerotised, cuticle weakly rugose. Epigynal posteromargin slightly protruded. Spermathecae separated by ca. 1.5 diameters. Copulatory openings adjacent. Copulatory ducts long, encircle spermathecae, forming ~ 3/4 loop from posterior to anterolateral connecting with the inner middle margins of spermathecae. Fertilisation ducts short, starting at postero-lateral margin of spermathecae, extending to lateral of posterior epigynal margin. Distribution. China (Yunnan) (Fig. 23 ). Figure 23.
