Other material examined: 1 ♂, CAS BLF 7390 ( CASENT 9005836 ), Province Toliara, Forêt Analalava, Ranohira , dry forest on sand, 22°35’30’’ S, 45°7’42’’ E, leg. Fisher, Griswold et al. 1–5.II.2003 GoogleMaps ; 2 ♂ (imm.), CAS BLF 7381 , same data as previous, but pitfall trap GoogleMaps ; 1 ♂, CASENT 9032812 , same data as previous, but beating low vegetation GoogleMaps .

Differential diagnosis: P. vohibasiensis differs from P. aureus in the colour pattern and the presence of an additional sclerotized process on the posterior gonopods basally to the membranous process ( Fig. 36D View Figure 36 ).

Description. Measurements: male holotype with 38 body rings, circa 40 mm long, 4.3 mm wide.

Coloration faded in alcohol. Antennae and legs reddish ( Fig. 36A View Figure 36 ). Head, collum, mesozona of body rings and anterior part of telson greyish-green ( Fig. 36B View Figure 36 ). Metazona of body rings gold-brown ( Fig. 36B View Figure 36 ).

Antennae protruding back to body ring 4 ( Fig. 36A View Figure 36 ). Male coxal processes absent, but coxae 3–7 swollen ( Fig. 36A View Figure 36 ). Preanal process well-rounded, longer than anal valves ( Fig. 36B View Figure 36 ).

Anterior gonopod sternite elongated into a wide, broadly-rounded lobe ( Fig. 36C View Figure 36 ). Coxite well-developed, in anterior view completely covering telopodite ( Fig. 36C View Figure 36 ). Telopodite process short and well-rounded, laterally curved, not extending beyond telopodite ( Fig. 36C View Figure 36 ).

Posterior gonopod telopodite disc covered with numerous teeth ( Fig. 36E View Figure 36 ). Membranous process large, basally wide, apically slightly tapering ( Figs 36D, E View Figure 36 ). Basally of membranous process with an additional long, finger-shaped process ( Fig. 36E View Figure 36 ).

Distribution and ecology: known from the subhumid forest of Vohibasia and Analava ( Fig. 30 View Figure 30 ).

Etymology: vohibasiensis , adjective, after the type locality, Vohibasia.
