Figs 52–53
Diagnosis
Differs from other species of Raduliverpa by having the limbus only very shallowly lobed, and the metaplical spinelike process (msp) very strongly curved, almost like a pig-tail, as opposed to the serrated limbus and much less curving msp seen in other species, see Frederiksen & Enghoff (2015) for R. serpentispina Frederiksen & Enghoff, 2015 and R. mitis Frederiksen & Enghoff, 2015, Kraus (1960) for R. serrata (Kraus, 1960) and Attems (1935) for R. sicaria (Attems, 1935).
Etymology
After Donatella Foddai, Italian myriapodologist, former resident of ‘Hotel Dolichoiulus’.
Material examined (total 2 ♂♂)
Holotype TANZANIA • ♂; East Usambara Mts, Tanga Region, Muheza District, Mgambo Proposed FR; 350 m a.s.l.; Sep. 1996; Norbert Cordeiro leg.; NHMD 621759.
Paratype TANZANIA • 1 ♂; same collection data as for holotype; NHMD 621760.
Description (male)
SIZE. Length 56–57 mm, diameter 2.9–3.0 mm, 70–71 podous rings, no apodous rings in front of telson.
COLOUR. Strongly faded after 22 years in alcohol, but faint indications of a medium-broad light dorsal stripe.
SUPRALABRAL SETAE. 4–5.
MANDIBULAR STIPES. Ventrodistally produced in strong triangular, slightly mesad process, distal margin very shallowly concave.
ANAL VALVES. With with moderate dorsal spine, a protruding ventral ‘corner’, margins raised, each with three setae on poorly developed ravelins.
LIMBUS (Fig. 52D). Striate, margin with very shallow lobes.
LEGS. With postfemoral and tibial pads, covering whole length of podomeres, from leg-pair ca 6, diminishing and eventually disappearing toward hind end.
FIRST PAIR OF LEGS (Fig. 52E–G). Prefemoral lobes with rounded-triangular in ventral view. Five to six coxosternal seta (CXS) close to lateral margin of coxosternum, well separated from prefemoral lobes. Prefemora with 2 of short mesapical setae (APS) and 5–12 peglike lateral setae (LPS).
STERNUM 9. Transversely rounded-triangular (not illustrated).
GONOPOD COXA (Fig. 52A–C). Slender, straight, almost parallel-sided, distolaterally with an almost equilateral triangular lateral process (LCS). Proplica (PP) simple, proplical lobe hibben behind fold of metaplica. Metaplica (MP) with a poorly delimited mesad flange (MF) basally, ca at mid-length with small, mesad triangular, process (mtp), distally with long, slender, strongly curved spinelike process (msp), process first directed basad then making a smooth 180° turn and projecting distad beyond gonopod tip.
GONOPOD TELOPODITE (Fig. 53). Arculus 80º. Torsotope (TT) extended, with angular lobe (TL) fitting into torsion. A long, stout post-torsal spine (PTS) making a full turn around post-torsal narrowing which is hence not evident. Solenomere and telomere originating near mesalmost part of telopodite, flexed back in front of and distal to torsotope. Solenomere (SLM) not very long, relatively stout, partially concealed within telomere, terminally flattened, pointed and transversely striate (Fig. 53D). Telomere (TM) shaped like an irregular bowl, smooth on the outside and along margins, with several contorted lamellae (tml) on the inside.
Distribution and habitat
Known only from Mgambo FR (formerly: Mgambo Proposed forest Reserve) in the north-east of the East Usambara Mts, altitude 350 m a.s.l. See Oliver et al. (2002) for information on the Mgambo FR.
