BONNER ZOOLOGISCHE MONOGRAPHIEN Nr. 58/2011 ventral apophysis, femur variable, wirhour dorsal bulge, tarsus without dorsal elongation, tarsal organ capsulate, procursus with ventral 'knee', without dorsal spines. Male bulb usually with uncus and ap- pendix (uncus absent in Ph. leruthi, appendix absent in Ph. nkoetye), weakly sclerotized embolus. Legs long, tibia 1 in males , tibia 1 L/d -60-80, legs without spines, usually without cur\'ed hairs (present in Ph. circukris and Ph. batepa), few vertical hairs, tibiae with three trichobothria each except tibia 1 (prolateral trichobothrium absent), retrolateral trichobothrium on tibia 1 at 3-6%. Abdomen q-lin- drical, male gonopore with four epiandrous spigots, ALS with one widened, one pointed, and variable number of CA'lindrically-shaped spigots (two in Ph. leruthi, fi\-e in Ph. bakweri, six in Ph. batepa, not known in other species), PMS with two small spigots. Sexual dimorphism slight, female chelicerae un- modified, body size as in males, legs slightly shorter (tibia l:-5-13). Sclerotized part of epigvmum con- fined to narrow posterior sclerite, with 'knob', inter- nal genitalia with pair of pore-plates of variable shape. Monophyly. This species group shares with the Ph. lamperti group a narrow epig\mal sclerite ( Figs. 929, 933), but lacks the cuticular color pattern on the abdomen distinctive of the Ph. hvnperti group (internal marks are often present). The Ph. circularis group is thus probably not monophyletic but para- phyletic with respect to the Ph. lamperti group. Relationships. As indicated above, the Ph. circularis group may be paraph}'letic and contain the mono- phyletic Ph. lamperti group. Within the Ph. circularis group, two species pairs can be identified: (1) Ph. circularis and Ph. batepa share a sclerotized process arising from the procursus 'knee' (chan 36), a small apophysis just proximal of the distal cheliceral apophysis (char. 21), and cur\'ed
