Type material: Holotype of Angaeus rhombifer Thorell, 1890: 1 juvenile from INDONESIA: Sumatra: leg. H. O. Forbes, depository unknown, not examined. Holotype of Angaeus rhombifer var leucomenus : 1 juvenile from BURMA: Tharawaddy, leg. Oates (BMNH 1895.9.21.869), images of the holotype were kindly provided by David Court. Syntypes of Stephanopis weyersi : 4 females, 1 juvenile from INDONESIA: Sumatra: no more data given (MNHN 10869), examined. Holotype and Paratypes of Paraborboropactus leguminaceus : CHINA: Yunnan: Xishuangbanna, Mengla County, Menglun Town (IZCAS, not examined).
Other material examined. BURMA: Kachin State: Bhamo, 1 immature female, collection Thorell, det. Thorell (NHRS-MAKA04460). MALAYSIA: Borneo: 1 female, West Sabah, 5º59' N 116º42' E, Kinabalu N.P., Poring Hot Springs, 650m, General, fr. Leaves, 8 April 1998, leg. P. Zborowski and C.L. Deeleman-Reinhold (RMNH ARA 15927). SINGAPORE: 1 immature female, labeled ‘ A. rhombifer Thorell , det. Workman’, collection Workman, no more data given (NMINH 1901.144.348); 1 male, Central Catchment, Venus Road, 13 November 2007, leg. D. J. Court (RMBR).
Synonymy. The syntypes of Stephanopis weyersi and illustrations of the type specimens of Paraborboropactus leguminaceus by Tang and Li (2009) unambiguously match material of A. rhombifer determined by Thorell and examined by me. The two immature females from Thorell and Workman collections are very close to maturing and the characteristic outline of the epigynum is clearly visible. The holotype of Angaeus rhombifer var leucomenus is a subadult female. The validity of a sympatric taxon based on juvenile specimens is difficult to assess. Fortunately, the characteristic outline of the epigynum is clearly visible. Based on this observation, I consider this name a junior subjective synonym of Angaeus rhombifer Thorell, 1890 .
Diagnosis. Males of A. rhombifer can be distinguished from other species of Angaeus by the robust, broad based RTA ( Figs 2 View FIGURE 2 A, 2B; Tang & Li, 2009: fig 20). Females can be distinguished by the lack of H and the presence of a narrow EF that somewhat widens over the copulatory openings ( Figs 2 View FIGURE 2 D, 3D; Tang & Li, 2009: fig 21).
Description. This species is well described by Tang and Li (2009). Measurements of the male from Singapore, Total: 5.1, Prosoma: length 2.8 width 2.7, Abdomen: length 3.1 width 2.7, Leg 1: femur 4.0, patella 1.4, tibia 3.8, metatarsus 2.5, tarsus 1.2 (total = 12.9). Leg 2: femur 3.7, patella 1.2, tibia 3.7, metatarsus 2.5, tarsus 1.2 (total = 12.3). Leg 3: femur 1.8, patella 0.9, tibia 1.3, metatarsus 1.1, tarsus 0.8 (total = 5.9). Leg 4: femur 2.1, patella 0.8, tibia 1.6, metatarsus 1.4, tarsus 0.8 (total = 6.7). Palp: femur 1.2, patella 0.4, tibia 0.8, tarsus 0.8. Leg formula = 1243.

Angaeus christae sp. nov. Figs 3 View FIGURE 3 A, 3B, 3E, 5A–D
Type material: HOLOTYPE: male from MALAYSIA: Borneo: West Sabah, 6º06' N 116º 50' E, Sorinsim, 5 yr old adjacent sec. forest, Loc 28, canopy fogging Melochia umbellata (Sterculiaceae) , tree 5 fog 4, leg. Floren, A., 25 February 1997 (RMNH.ARA.15917).
Other material examined. MALAYSIA: Borneo: 1 female, West Sabah, 6º06' N 116º 50' E, Sorinsim, 5 yr old adjacent sec. forest, Loc 34, canopy fogging Melochia umbellata (Sterculiaceae) , tree 10 fog 2, leg. Floren, A., 11 March 1997 (RMNH.ARA.15946).
Etymology. The species is named in honor of Christa L. Deeleman-Reinhold.
Diagnosis. Males of A. christae sp. nov. can be distinguished from males of other species of Angaeus by the absences of a MA; females by the presences of kidney shaped S.
Description. Male (holotype): Total length: 5.2; prosoma length: 2.6, width: 2.4. Leg I: femur 3.2, patella 1.2, tibia 2.6, metatarsus 1.7, tarsus 0.8. Leg formula 4132. Coloration and markings as in Fig 3 View FIGURE 3 A. Palps as in Figs (5A, 5B). Female: Total length: 5.2; prosoma length: 2.6, width: 2.4. Leg I: femur 3.2, patella 1.2, tibia 2.6, metatarsus 1.7, tarsus 0.8. Leg formula 4132. coloration and markings as in Fig 3 View FIGURE 3 B. Epigynum and vulva as in Figs 3 View FIGURE 3 E, 5C and 5D.
Distribution. Known only from the type locality.
Other material examined. Angaeus comatulus Simon, 1909: 145 . Type material: Syntypes of Angaeus comatulus : 2 immature females from VIETNAM: ‘Tonkin’ (MNHN 22168/1573), no more data given, examined ( Fig 1 View FIGURE 1 A).
