Figs 5 A, 20A, B, 20D

Borboropactus bituberculatus Simon, 1884: 301 .

Regillus bituberculatus ( Simon). Simon 1895 : 1049, fig 1093.

Regillus divergens Hogg 1914: 57 . Hogg 1915: 461, fig 29; Chrysanthus 1964: 89, fig 12–14. Holotype from Setakwa River, South New Guinea, in the BMNH, not examined. New synonymy.

Borboropactus hainanus Song, 1993 . Male holotype from China, Hainan, Changjiang Co., Bawangling Mountains, 15 May 1990, M.B.Gu, IZCAS-Ar9362, not examined. New synonymy.

Type material: Syntypes of B. bituberculatus . Two females from New Guinea in MNHN 5460/1572, no more data given, examined ( Figs 5 A, 20D).

Synonymy. In both instances above, B. divergens and B. hainanus are well illustrated facilitating unambiguous identification. Further, the former species is from the same locality as B. bituberculatus .

Other material examined. INDONESIA: Irian Jaya: Waigeo Island, 1 male, Yembekaki, 0–180 m, 20–23 January 2001, A. Riedel ( MHNG). Urbinasopen: 1 male, Gunung Susu, 0–450 m, 25 January 2001, A. Riedel ( MHNG). Manokwari Province: 1 female, Wandammen Bay, Wondiwoi Mts., Wasior, 300–980 m, 3 January 2001, A. Riedel ( MHNG). PAPUA NEW GUINEA: Madang Province: 1 female, Beiteta Road, 3.5 km W of North Coast Road, 80 m, 1 March 1989, Stop # 89–4, D. H. Kavanaugh, G. E. Ball and N. D. Penny ( CAS).

Diagnosis. Resembles and likely to be confused with B. cinerascens . However, it could be separated from B. cinerascens by the large oval MA, broad based E and C ( Figs 20A–20B ). Females are separated by the stouter ET ( Fig 20 D).

Description. Habitus as in Fig 5 A. Male palps as in Figs 20A–20B . Described in detail elsewhere ( Song et al. 1999; Chrysanthus 1964; Song & Zhu 1997; Tang & Li 2010).

Distribution. China, Island of New Guinea.
