urn:lsid:zoobank.org:act:5442A6D8-CF81-4A08-82D1-C3EEEFD037FE

Material examined: 3 ♂ Holotype: 1 ♂ (40 mm long), FMMC 8212 , Madagascar, Province Toliara, Forêt de Vohibasia , subhumid forest, 780 m, 22°27.5’ S, 44°50.5’ E, leg. S. Goodman, 10–16.I.1996.

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 ; 2 ♂ (imm.), CAS BLF 7381 , same data as previous, but pitfall trap ; 1 ♂, CASENT 9032812 , same data as previous, but beating low vegetation .

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 ).

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 ). Head, collum, mesozona of body rings and anterior part of telson greyish-green ( Fig. 36B ). Metazona of body rings gold-brown ( Fig. 36B ).

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

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

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

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

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