Cacuminostreptus mazowensis View in CoL sp. n. Mwabvu

Fig. 12 View FIGURE 12 a, b

Type material: Holotype: ZIMBABWE: 1 3, Mazowe Dam [17 0 30'S, 30 0 58'E], 13.xii.08, T. Mwabvu ( NMSA 21945)

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 View FIGURE 12 a, b ).

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 View FIGURE 12 a, b View FIGURE 12 c, d ).

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

Gonopod: ( Figs 12a, 12b View FIGURE 12 a, b ) 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 View FIGURE 12 a, b ).

Apical proplica wide and rounded ( Fig. 12a View FIGURE 12 a, b ), 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 View FIGURE 12 a, b ).

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.
