Megaskamma improvisa: Attems 1934 , p. 13, figs 14–17; Synonymy by Hoffman 1971 Plagiotaphrus improvisus: Hoffman 1971 View in CoL

Type material (not examined): ANGOLA: 1 male, near Cuanza river, Biė District, [12 0S, 17 0 30'E], i.1932, F. Haas ( SMF 1694).

Diagnosis: Apical proplica tapering and acute, subapically produced into a large, rounded lateral lobe at the level of telopodite knee ( Fig. 2 View FIGURE 2 a); antetorsal process describes a semi-circle and crosses the proplica ( Fig. 2 View FIGURE 2 b).

Description: (based on Attems 1934)

Size: Maximum body width 10.5 mm.

Number of body rings: 56.

Colour: Body dark brown; legs dark red-brown.

Collum: Produced into an anterior lobe, with 3 complete folds and an incomplete fold.

Prefemoral process of 1st pair of male legs: Rounded laterally, nipple-shaped and acute apically ( Fig. 2 View FIGURE 2 c).

Gonopod: ( Figs 2 View FIGURE 2 a, 2b) Sternite triangular; paracoxite rounded.

Proplicae wider at level of telopodite knee; apical proplica tapering, acute and overlapping proximal lateral process. Subapical proplica extended into a setose, rounded lateral lobe ( Fig. 2 View FIGURE 2 a).

Medial edge of end process convex distally.

Post-knee telopodite broad proximally, with a spiral distal to paracoxite, distal half narrows with two short branches at extremity; antetorsal processes not reaching paracoxite apex, strongly curved (describing a semicircle), extend medially and cross proplica ( Fig. 2 View FIGURE 2 b).

Distribution: Known only from type locality, General Machado, central Angola.

Remarks: According to Hoffman (1971) and Krabbe (1982), the type material is in the SMF, however, the material is not in the collection. The material is said to have been sent to Krabbe in 1975 and it was not returned to the collection. Krabbe (1982) acknowledged having studied the gonopods after finding them in NHMW.
