Paratypes: ZIMBABWE: 4 3, 9 Ƥ Mazowe Dam [17 0 30'S, 30 0 58'E], 13.xii.08, T. Mwabvu (NMSA 21992)

Additional material examined: ZIMBABWE: 1 3, Mazowe Dam [17 0 30'S, 30 0 58'E], T. Mwabvu (NMSA 21970); 1 3, Mazowe Dam [17 0 30'S, 30 0 58'E], 19.xi.1997, T. Mwabvu (NMSA 20529); 1 3, Highlands Suburb, Harare [17 0 49'S, 31 0 02'E], xii.2007, M. Cummings (NMSA 21944).

Etymology: Refers to the type locality, Mazowe Dam, Zimbabwe.

Diagnosis: Lateral margin of metaplicae strongly convex. Apical metaplical process concave apically, with lateral and medial apices produced into short acute horns (Figs 12a, 12b).

Description: Size: Body length 3 135–150, Ƥ 140–160 mm; maximum body width 10–15 mm.

Number of body rings: 59–65.

Colour: Body black; legs and antennae dark brown.

Collum: Produced into a narrow anterior lobe, with 4–6 complete striae and 2–7 incomplete striae (Fig. 12d).

Pre-femoral process of 1st pair of male legs: Proximally wide, medial extension laterally deflected (Fig. 12c).

Gonopod: (Figs 12a, 12b) Apex of sternum not reaching level of paracoxite apex; paracoxite not fused tightly to metaplica, apex flat.

Opposite telocoxites parallel, medial edges in contact (Figs 12a, 12b).

Apical proplica wide and rounded (Fig. 12a), with a triangular medial lobe, and overlaps lateral metaplical process proximally.

Metaplicae convex laterally, distally with a tapering mesial hump.

Lateral metaplical process short; broad proximally with constriction; arrowhead-shaped, crescent-shaped and tapering distally.

Lateral metaplical process and apical metaplical process at right or obtuse angle.

Apex of apical metaplical processes concave, with short horns (Figs 12a, 12b).

Antetorsal processes extend past paracoxite apex.

Distribution: Known from Harare and Mazowe Dam (20 km north of Harare), Zimbabwe.

Remarks: Although the gonopod of C. mazowensis closely resembles that of vumbaensis, the metaplicae are less convex and the apex of the apical metaplical process is flat in C. vumbaensis . In C. mazowensis the apex of the apical metaplical process is concave.
