HOLOTYPE 3 KENYA, Gede, 3°28’S, 39°18E, 29.iv.1981, CIE A13123 (NHML). – PARATYPES: 2 3, 3 ƤƤ, strongly fragmented, KENYA, Changamwe 4 miles W of Mombasa, 4°01’30’’S, 39°37’45’’E, 21–30.iii. (?) 1909, E.A. Mearns leg. (USNM, ZMUC).

Etymology. The specific epithet is a Latin noun in apposition meaning “shoe” and refers to the tip of the posterior gonopod which somewhat resembles a (rather distorted) shoe.

Diagnosis. A species of Parabolus in which the anterior gonopod coxa has a distinct distolateral shoulder, and the terminal segment of the posterior gonopod has a faintly serrate mesobasal ridge, a strongly concave distolateral profile and no slender apical process.

Descriptive notes (mainly based on holotype): As Crurifarcimen vagans except as noted:

57 podous rings, no apodous rings. L 14 cm, B 13.4 mm. 10–11 rows of ocelli in six horizontal series, 41–44 ocelli per eye. 2+2 labral teeth, labral setae not visible. Lamellae linguales each with 5–6 distal setae. Collum smooth, no striae, with marginal furrow at anterior margin. Body rings: tergo-pleural suture visible on pro-, meso- and metazonite. Terga smooth, except for fine oblique striae ventrally on mesozona and fine, dense longitudinal striae on metazona. Ozopores 1 diameter in front of suture. Legs: length 51% of body width (markedly shorter than in P. dimorphus). Telson as in Crurifarcimen v. but dorsal profile straight.

Male sexual characters. Anterior gonopods (Figs 54–55) as in P. dimorphus, except that the coxa has a marked distolateral ’shoulder’, is apically truncate and lacks the internal ridge at the base of the mesal process Posterior gonopods (Figs 56–57) as in P. dimorphus, except for shape of terminal segment which has a low, faintly serrate mesobasal ridge (instead of the coarsely serrate lobe of P. d i m o r p h u s), a strongly concave distolateral profile, concavity basally delimited by strong triangular tooth; distolateral surface deeply hollowed, forming a long, curved trough; oral wall of trough with a low subtriangular lobe.

Female sexual characters as in P. dimorphus.

Distribution. Only known from two sites in SE Kenya. (Fig. 84) This is the only species of Pachybolini known from Kenya, excepting the widespread Epibolus pulchripes.
