(?) 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 .
