urn:lsid:zoobank.org:act: 052AECF5-0923-403F-AEC2-F2E1F918DB22

Figs 1, 10–11

Diagnosis

Differs from other species of Morogorius, except M. cochlear sp. nov., by the short, compact parasolenomere. Differs from M. cochlear by the pointed shape of the parasolenomere, the slenderer prefemoral process and the larger coxal process (Fig. 11, compare with Fig. 12).

Etymology

Named after the type locality. Noun in apposition.

Material examined (total 1 ♂)

Holotype TANZANIA • ♂; Udzungwa Mts, Kitungulu Forest Reserve; 08°09′ S, 36°05′ E; 1500 m a.s.l.; Jan. 1996; M. Andersen, P. Gravlund and A. Jakobsen leg.; NHMD 1184573.

Description (male)

SIZE. Length ca 27 mm, max. width 4.6 mm.

COLOUR. After 28 years in alcohol head brownish; dorsal side of all rings including collum brownish with contrasting whitish paranota on all rings, post-sulcus area of rings also whitish; telson anteriorly brownish, posteriorly whitish; antennae, legs and ventral side light brown.

COLLUM. With two setae close to anterior margin.

BODY RINGS (Fig. 10A–C). Metazonites ca 1.6 times as broad as prozonites, with 1+1 small, thin setae anteriorly, a prominent transverse sulcus on rings 5–18, granulated with irregular shallow, longitudinal striae behind transverse sulcus. Paranota rectangular until ring 14, thereafter posterior corners projecting increasingly backwards, triangular. Ozopores in smooth peritremata on edge of paranota, ca midway between anterior and posterior margin (Fig. 10B–C). Sides of rings with uniform tuberculation, no larger tubercles along posterior margin.

LEGS (Fig. 10F). Length 1.2× maximum body width.

GONOPODS (Fig. 11). Coxa (cx) with a long, stout, conical apical process (cxp) on anterior side, two long setae (as) on anterior surface basal to process, a field of ca a dozen setae (ls) on lateral surface. Prefemoral part (prf) ca 2½× as long as broad, distally delimited by distinct cingulum (ci) on ventral side. Efferent duct running straight on meso-dorsal side of prefemoral part, at level of base of parasolenomere bending laterad into hollowed side of acropodite. Prefemoral process (prp) with slender club-shaped outline, apical part sub-rhomboid, dorsal surface concave (accommodating solenomere), apically forming hood over tip of solenomere; a few denticles on distal margin and subdistally on dorsal margin. Solenomere (slm) shorter (ca 0.8 ×) than prp, stout and slightly tapering in basal ⅔, then abruptly narrower, forming slender hook, the solenomere s. str. (sslm); a slightly serrate high, short ridge (s r) facing concave side of sslm. Parasolenomere (ps) originating mesal to slm, much shorter than slm, stout, pointed.

Distribution and habitat

Known only from one site in the Kitungulu Forest Reserve, Udzungwa Mountains (Fig. 1). Collected at 1300 m a.s.l.
