Figs 6, 9, 29
Diagnosis
Medium-sized. Gonopod coxa (Fig. 9) without a lateral process; cucullus small. Distinguished from other species, i.a., by the characteristically shaped posterior telomeral lamella (Fig. 29).
Etymology
The name honours Tarombera Mwabvu in recognition of his work on the taxonomy of African millipedes.

Type locality
TANZANIA: Iringa Region, Iringa District, Udzungwa Mts, New Dabaga/Ulangambi FR, 08°06’ 47.4” S, 35°56’ 50.4” E, montane, 1800–1955 m asl.
Description (male)
DIAMETER. 1.8–1.9 mm, 43–45 podous rings.
COLOUR. After 13 years in alcohol brownish yellow, dorsolaterally dark brown, a broad middorsal pale stripe, a narrow blackish lateral stripe at ozopore level.
ANAL VALVES (Fig. 6C, F). Each with a long, slightly curving dorsal spine and a small, triangular ventral one; marginal rim raised, setiferous tubercles barely developed, not on ‘ravelins’.
LIMBUS. With long, slender, apically denticulate lobes, separated by wider sinuses.
TARSAL SETATION. Normal.
GONOPOD COXA (Figs 9, 29). About 4 × as long as wide; lateral margin evenly convex in distal 2/3; cucullus (cu) small, smoothly rounded, without processes. Metaplical flange (mf) ending in triangular, apicad process; metaplical mesal margin straight, but with triangular process (mp) just below level of arculus. Metaplical shelf (ms) regularly rounded, projecting posteriad as well as mesad, continuing without transition in metaplical shelf-spine (mss). Metaplical shelf-spine (mss) of medium length, curving first mesad, then distad, then pointing mesad again; in specimen prepared for SEM pointing obliquely basad, tip reaching beyond basomere.
GONOPOD TELOPODITE (Fig. 29). Solenomere with a long, straight, mesad, proximal spine (ps). Telomere distally with two branches:
• a large, convoluted anterior lamella (al) with smooth edges except for a few distal denticulations,
• a posterior-distal lamella (pl); distal margin of pl deeply laciniate in apical part, basally produced in slender process furcating into larger branch (plp1) with long-spinose margins and smaller, slender branch (plp2) with large spine at base and terminally bifurcating.
Distribution and habitat
Known from two forest reserves in the Udzungwa Mts: New Dabaga/Ulangambi FR and Kigogo FR. Altitudinal range: 1800–1955 m asl. Habitat: montane forest.
Coexisting species
All four species known from Kigogo FR, i.e., C. quasimodo sp. nov., C. scopus sp. nov., C. howelli sp. nov. and C. mwabvui sp. nov., were found in the same samples. In New Dabaga/Ulangambi FR, C. dabagaensis, C. gracilior sp. nov., C. netus sp. nov. and C. termini sp. nov. were found in the same samples as C. mwabvui sp. nov. In addition, C. krai sp. nov., C. malleolus sp. nov., C. nectarinia sp. nov., C. teres sp. nov., C. vandenspiegeli sp. nov. and C. vilici sp. nov. occur in New Dabaga/Ulangambi FR.
