Figs 4, 8–11, 34
Diagnosis
Medium-sized. Differs from all other group members by the presence of a long, gently curved, longitudinally fluted spine (pxs) on the proximal lobe of the telomere. The profile of the coxa (Fig. 9) is also distinctive, as is the spine-like tip of the anterior lamella (al) of the telomere.
Etymology
The name is a Latin adjective meaning ”woven” or ”knit” and refers to the intricately interwoven gonopod telopodites.

Type locality
TANZANIA: Iringa Region, Iringa District, Udzungwa Mts, New Dabaga/Ulangambi FR, 08°00’ 26.6” S, 35°56’ 06.1” E, montane forest, 1910 m asl.
Description (male)
DIAMETER. 1.9–2.3 mm, 41–45 podous rings.
COLOUR. After 12 years in alcohol pale yellowish, with paramedian dark bands flanking a broad middorsal light stripe, a narrow blackish lateral stripe at ozopore level.
ANAL VALVES. Each with a long, slightly curving dorsal spine and a small to well-developed, triangular ventral one; marginal rim raised, setiferous tubercles on small ‘ravelins’.
LIMBUS (Fig. 4C). With almost equilateral triangular lobes with rounded, spinulose tips, separated by parabolic sinuses; lobes striate on external surface.
TARSAL SETATION. Normal.
GONOPOD COXA (Figs 9–11). About 4 × as long as wide. Lateral margin very shallowly convex from base up to beyond level of prl and ms, then curving lateral and together with apical margin forming blunt, disto-lateral process of cucullus; main part of cucullus subrectangular in anterior view. Metaplical flange (mf) ending in blunt process; metaplical mesal margin straight up to level of arculus, then abruptly turning mesad at ca. 130° angle (base of mss), then turning apicad at ca. right angles. Metaplical shelf (ms) regularly rounded, projecting posteriad as well as mesad. Metaplical shelf-spine (mss) originating from anterior-mesal end of ms, very long, first directed apicad, then mesad and apically slightly obliquely distad, in situ crossing over with opposite mss.
GONOPOD TELOPODITE (Figs 8, 10–11). Solenomere with a very long, gently curved proximal spine (ps) set in a socket with more or less spinulose rim; sometimes a tiny denticle (ps2) at base of ps. Proximal lobe of telomere (pxl) with a long, gently curved, longitudinally fluted spine (pxs). Telomere distally with three branches:
• an S-shaped anterior lamella (al), broad at base, then narrowing and ending in curved spine-like tip,
• a large, irregularly shaped intermediate lamella (il),
• a small, rounded posterior lamella (pl).
Distribution and habitat
