Diagnosis

Differs from other species of the genus by the shape of the subapical lobes on the postnodal telepodite, and by the shape and curvature of the solenomere.

Material examined

Holotype

TANZANIA • ♂; Iringa Region, Udzungwa Mts, Udzungwa Scarp FR, above Chita Village; 1050 m a.s.l.; 26–29 Oct. 1984; N. Scharff leg.; pitfall traps in intermediate rain forest; NHMD 50501 .

Paratypes

TANZANIA • 9 ♂♂, 2 ♀♀; Iringa Region, Udzungwa Mts, Udzungwa Scarp FR, above Chita Village; 1050–1650 m a.s.l.; 26 Oct.–13 Nov. 1984; N. Scharff leg.; intermediate and montane rain forest; NHMD 621669 .

Description (modified after Hoffman 2005) Male

SIZE AND SHAPE. Body length ca 40 mm. Maximum width 7.7 mm. W/L ratio 19%. Height of body ring eight 5 mm. H/W ratio = 65%.

COLOUR ( Fig. 6 ). Face, collum, metaterga medium brown, legs and antennae lighter, prozona and sterna nearly colourless.

STERNAL PROCESS ON BODY RING 6. Transverse across sternum with dark brown edge and long setae.

HYPOPROCT. Almost semicircular, with moderate round median projection, paramedian tubercles above normal size, projecting beyond edge of sclerite.

GONOPOD ( Fig. 7 ). Gonocoxa with paracannular setae. Telopodite mesonodal. Process M twice as wide at base and slightly longer than process L, both curved laterad. Postnodal teleopodite relatively short, curved dorsomesad, with subapical triangular lobe on lateral side and uncate lobe on mesal. Solenomere of telopodite curved away from uncate subapical lobe ( Fig. 7 A–B).

Distribution

Known only from two very close sites in the Udzungwa Scarp FR ( Fig. 2 ).
