Diagnosis. Differs from the only known congener, P. zophoribates sp. nov., by being smaller (diameter of males 4.4–4.8 mm, vs. 6.0– 6.6 mm), by having the apical proplical lobe almost semi-circular with a short, pointedtriangular or rounded-triangular mesapical process, and by having the apical lobe of the metaplica irregularly triangular.

Description. Males.
SIZE. Body length 52–60 mm. Diameter 4.4–4.8 mm. 41–43 body rings.
COLOUR. Live colour ( Fig. 1 View FIGURE 1 ) black, prozonites dull with a greyish tinge, metazonites shining deep black; antennae red-brown; legs contrastingly bright red; superficially resembling a miniature version of the common East African Epibolus pulchripes ( Gerstäcker, 1873) (fam. Pachybolidae , order Spirobolida ). Colour of preserved specimens faded, legs reddish orange.
MANDIBLES ( Fig. 6 View FIGURE 6 ). Stipes with apicoventral lobe, a soft pad apically on the lobe. Odontomere (od) fused with psectromere (ps); sectile edge (se) of psectromere with four lobes; a meso-dorsal lobe (mdl) present between od and se. 11 pectinate lamellae (pl). Molar plate with a distal transverse groove (mg) occupying ca. 1/6 of the mesal surface. Dorsal surface of mandible with a group of small pointed pegs (pp) between pectinate lamellae and molar plate ( Fig. 6 D View FIGURE 6 ).
GNATHOCHILARIUM ( Figs 3 A–D View FIGURE 3 ). Basal edge of median depression of mentum (mda) sharp, overlying main part of mentum and thus delimiting an arched, transverse cavity. Stipites (st) with a longitudinal patch of setae (sbs) in basal half.
BODY RINGS ( Fig. 2 A View FIGURE 2 ). A single row of large sigilla; sometimes additional, incomplete rows of smaller sigilla.
LEGS. As long as body diameter. First pair with a patch of setae on coxosternum ( Fig. 5 A View FIGURE 5 ).
GONOPODS ( Figs 5 C View FIGURE 5 , 7 View FIGURE 7 ). Proplica parallel-sided, apically with an almost semi-circular lateral lobe (apl), mesapically with a short, triangular process (map). Metaplica with mesal margin turning laterad at ca. 45° just before end of proplica, apical lobe (aml) subtriangular, projecting laterad and apicad, more or less resembling the head of a seal. A sub-circular sport of dark colour subbasally on posterior surface of metaplica, position of dark spot variying between individuals, but always symmetrical. Antetorsal process (atp) of telopodite ( Fig. 5 C View FIGURE 5 ) projecting distad, completely hidden between pro- and metaplica.
Females. SIZE. Body length 57–61 mm. Diameter 5.4–5.7 mm. 40–44 body rings.
LEGS. Length 0.75 × body diameter.
Distribution. Known from three massifs of the Eastern Arc Mountains: East Usambara, Kanga and Udzungwa Mts ( Fig. 9 View FIGURE 9 ).
