Figs 5, 9, 17
Diagnosis
Medium-sized. Without a proximal spine on the solenomere, a character shared only by C. malleolus sp. nov. and C. hamerae sp. nov. Differing from these species (and indeed from all other species in the group) by the profile of the gonopod coxa (Fig. 9).
Etymology
The name is a Latin adjective referring to the type locality.

Type locality
TANZANIA: Morogoro Region, Kilombero District, Udzungwa Mts, Mwanihana FR, 1800–1850 m, montane rain forest.
Description (male)
DIAMETER. 2.2–2.4 mm, 44–46 podous rings.
COLOUR. After 30 years in alcohol bleached but with traces of a broad, light dorsal stripe, flanked by dark dorsolateral bands, and thin dark lines at ozopore level.
ANAL VALVES. Each with a very long and slender, slightly curving spine and a small, triangular ventral one; marginal rim raised, setiferous tubercles well developed, on small ‘ravelins’.
LIMBUS. With broadly rounded lobes, separated by short stretches (ca. 1/4 -½ lobe width) of straight margin; lobes ca. as broad as long; deeply striate on external surface. Surface between lobes forming shallow concavity behind straight margin.
TARSAL SETATION (Fig. 5A). Normal.
GONOPOD COXA (Figs 9, 17). About 3½ × as long as wide. Lateral margin basally straight, then curving slightly laterad and forming lateral triangular process (lp) before continuing to rounded coxal tip; cucullus (cu) hence approximately triangular in outline. Metaplical flange (mf) ending in approximately equilateral triangular process; metaplical mesal margin straight up to level of metaplical shelf (ms). ms simple, regularly rounded, projecting mesad as well as posteriad, continuing anterior-mesally in metaplical shelf-spine (mss) without a marked transition. mss short to medium long, curving first anteriad, then mesad, then posteriad, almost only in horizontal plane.
GONOPOD TELOPODITE (Fig. 17). Solenomere without spines or other secondary branches. Telomere distally with two branches, both curving 180° anteriad: Anterior lamella (al) smaller than posterior lamella (pl), both with several lobes with partly serrate-laciniate edges. Due to 180° curvature, distal part of pl dominating the anterior view, forming a roughly ellipsoid structure with the long axis oriented basal-apical.
Distribution and habitat
Known only from Mwanihana FR. Altitudinal range: 1800–1850 m asl. Habitat: montane rain forest.
Coexisting species
None known.
