Figs 6, 40–42
Diagnosis
Differs from other species of Lamelloramus, including the undescribed one from Mt. Kilimanjaro mentioned above, by the presence of a very long basal solenomeral spine (BSS) (vs absent or very short in other species) as well as in the outline of the “side-branching telomeric lamella” and the detailed shape of the gonopod coxa.
Etymology
After Sara B. Frederiksen who described the genus Lamelloramus (Frederiksen 2013b).
Material examined (total 1 ♂)
Holotype TANZANIA • ♂; Morogoro Region, Uluguru South FR, forest above Linzi village; 07°06′ S, 37°40′ E; Nov. 1993; The Uluguru Biodiversity Survey leg.; NHMD 621744.
Description (male)
SIZE. Length 49 mm, diameter 3.3 mm, 55 podous rings, no apodous rings in front of telson.
COLOUR. After 25 years in alcohol all faded.
SUPRALABRAL SETAE. 6.
MANDIBULAR STIPES. Distal margin distinctly concave-bilobed.
ANAL VALVES. With well-developed dorsal spine, no ventral spine, margins not raised, each with three sessile setae.
LIMBUS (Fig. 41E). With simple, triangular lobes (strongly worn on unique specimen).
LEGS. Ventral pads on postfemur and tibia from leg-pair 4, diminishing and eventually disapperaring towards posterior.
FIRST PAIR OF LEGS (Fig. 40A–C). Prefemoral lobes broad, triangular in ventral view. One to three coxosternal setae (CXS) close to lateral margin of coxosternum, well separated from prefemoral lobes. Prefemora with two short mesapical setae (APS), lateral setae absent or indistinct.
STERNUM 9 (Fig. 40D). Large, in the shape of an inverted triangle on a stout foot, with an irregular keel from bottom to top.
GONOPOD COXA (Fig. 41A–D). Quite stout, margins shallowly sinuous. Proplica (PP) with shallowly sinuous mesal margin, proplical lobe hidden under anterior metaplical lobe (ml). Metaplical flange (MF) without a process. Metaplica (MP) forming apical ‘crown’ with a system of ridges delimiting two broad troughs (tr1, tr2), one shallow, one deep; on anterior side forming broad basad lobe (ml) covering proplical lobe; on lateral side with semicircular lobe (mll).
GONOPOD TELOPODITE (Fig. 42). Arculus 90°. Torsotope (TT) compact, with a long post-torsal spine (PTS). Post-torsal narrowing (PM) not very pronounced, relatively short. Solenomere (SLM) very long, longer than telomere, whiplike, with an exceptionally long, first straight, then strongly curved basal spine (BSS) otherwise without any outgrowths; solenomere making a large U-bend on dorsal side of telomere, apically fluted and spiralled (Fig. 42F–G). Telomere (TM) relatively simple, mesally dividing into a broadly rounded-triangular mesad(-posteriad) lamella (stl = “side-branching telomeric lamella” sensu Frederiksen 2013b), and a long bandlike, tapering process (tp) which turns laterad and then makes an almost complete loop in a plane perpendicular to main axis of telopodite.
Distribution and habitat
Known only from the Uluguru South FR.
