Epidius ganxiensis ( Yin, Peng and Kim, 1999) . Tang et al., 2009: 44, figs 3a–j.

Type material: Syntype of Epidius rubropictus : VIETNAM: 1 male, ‘Tonkin’ ( MNHN 22347), no more data given, examined.

Other material examined. INDONESIA: Sumatra: 1 female, Utara Deli Serdang Reserve, Naturelle de Sipispis, Region de Dolokmerawan, 380 m, 17 November, 1985, leg. C. Lienhard ( MHNG).

Remarks. Tang et al. (2009) recognized that Philodromus ganxiensis was misplaced in Philodromus and transferred it to Epidius . The illustrations provided by these authors for Epidius ganxiensis and my examination of the type of E. rubropictus (MNHN 22347) leave no doubt that both names stand for a single species.

Diagnosis. Males can be separated by the shape of the MA. The MA has a long stalk, ending with a stout rounded tip ( Figs 35 C). The E is thin and long, originating from the proximal end and extending over the distal end of the tegulum. Females can be separated by the thin, long copulatory ducts and the oval S ( Figs 35 D, E). Females may also be separated by the disproportionately large spermathecal chambers ( Figs 35 D, E).

Description. Female. from Indonesia: Sumatra. Total length: 3.3; prosoma length: 0.7, width: 1.5. Leg I: femur 2.0, patella 0.5, tibia 2.0, metatarsus 1.6, tarsus 0.9. Male palp as in Fig 35 C. Female vulva and epigyne as in Figs 35 D, E. For a good description of this species see also Yin et al. (1999) and Tang et al. (2009).

Distribution. China, Indonesia (Sumatra), Vietnam.
