Etymology. Named for the Betsileo, one of the major tribes in Madagascar. The species name is a noun in apposition.
Diagnosis. Closely related to the type species P. madagascariensis , with almost identical palps, distinguished by the more widely spread male cheliceral apophyses (compare Figs 132 and 133 View Figures 131–138 ). The MCZ has another close relative from the ‘eastern highlands’, differing primarily by details of the dorso-distal element of the procursus (‘d’ in Fig. 134 View Figures 131–138 ; MCZ 34057).
Male (holotype). Total length 1.8, carapace width 0.76. Leg 1: 21.9 (5.5 + 0.3 + 5.3 + 8.3 + 2.5), tibia 2: 3.1, tibia 3: 2.2, tibia 4: 2.8; tibia 1 L/d: 83. Habitus as in Figures 102 and 103 View Figures 102–121 . Carapace ochre-yellow with blackish margin; sternum blackish except laterally. Legs ochre-yellow with dark rings on femora and tibiae (subdistally). Opisthosoma ochre-grey, with blackish spots posteriorly and light grey spots shining through cuticle. Ocular area distinctly separated from carapace, with each triad on additional elevation; distance PME-PME 260 Mm; diameter PME 80 Mm; distance PME-ALE 30 Mm. Thoracic furrow indistinct, only frontally slightly indented dark line. Sternum wider than long (0.56/0.46). Chelicerae as in Figures 133, 136 View Figures 131–138 and 141 View Figures 139–146 , tips of apophyses without modified hairs ( Fig. 140 View Figures 139–146 ), distance between tips of apophyses 215 Mm. Palps as in Figures 134 and 135 View Figures 131–138 , trochanter with three apophyses, one prolateral, one ventral pointing in retrolateral direction, and one retrolateral (‘p’, ‘v’, and ‘r’ in Fig. 142 View Figures 139–146 ); procursus with distinctive dorsodistal element (‘d’ in Fig. 134 View Figures 131–138 ). Embolus simple membranous tube (‘e’ in Fig. 134 View Figures 131–138 ). Legs without spines, without curved hairs, few vertical hairs (most hairs missing in holotype, but present in other specimens); retrolateral trichobothrium of tibia 1 at 10%; tarsus 1 with>20 pseudosegments (distally about 20 very distinct). Epiandrous spigots and ALS spigots as in Figures 146 View Figures 139–146 and 148 View Figures 147–153 .
Variation. Tibia 1 in 20 other males 4.8–5.8 (x = 5.34). Some males have more dark spots dorsally on the opisthosoma.
