Eviulisoma kwabuniense Kraus, 1958: 3 (holotype (not studied) in the Überseemuseum Bremen).
Diagnosis
Differs from all other species of Eviulisoma by the presence of a basal acropodital process. Further differs from other Udzungwan members of the E. kwabuniense group by the combination of largely identical, smooth map and iap, and a relatively short solenophore with three lobes of approximately equal length.
Material studied (total: 1 ♂)
TANZANIA: 1 ♂, Iringa Region, Iringa District, New Dabaga/ Ulangambi FR, 08°05′34.5″ S, 35°55′31.3″ E, montane, 1800–1900 m a.s.l., Plot 16, 15–16 Nov. 2000, Frontier Tanzania leg. (ZMUC).
Descriptive notes (male)
Information on the holotype, from Kraus (1958), in square brackets when different.
SIZE. Length 15 mm, max. width 1.8 mm [1.6 mm].
COLOUR. Completely pallid after 17 years in alcohol, possibly not due to fading, cf. remarks under E. ottokrausi sp. nov. [very pale, just weakly horn brown mainly on collum and metazonites].
ANTENNAE. Reaching back to end of ring 3.
BODY RINGS. Paranota completely missing. Stricture between pro- and metazonite clearly striolate. No setae seen on post-collar body rings.
HYPOPROCT. Trapezoid, with three prominent apical tubercles.
LEGS. Short, stout, length 0.9× body width. Relative lengths of podomeres: prefemur = femur> tarsus> postfemur = tibia. Scopulae strongly developed on femur, postfemur, tibia and tarsus, continuing until last legs, except on femur.
STERNUM 5. A tongue-shaped process between legs 4.
STERNUM 6. Deeply excavated. Rim of excavation simple.
GONOPODS (FIG. 9). Coxal lobe (cxl) large (not seen in Fig. 9). Prefemoral part (prf) ca half as long as acropodite. Acropodite with a small basal, finger-shaped process (bap); surface of bap with honeycomblike microsculpture (Fig. 9C). Mesal and intermediate acropodital processes (map and iap) largely identical, slender, smooth, pointed rods (iap diastally hooked). Solenophore (sph) large, ca ⅔ as long as acropodital processes, folded around solenomere (slm), three-lobed, dorsal lobe (sph-d) large, semicircular, ventral lobe (sph-v) pointed-triangular, intermediate lobe (sph-i) smaller, triangular.
Distribution and habitat
Known only from the New Dabaga/ Ulamgambi FR. Altitudinal range 1800–2100 m a.s.l. (upper limit according to Kraus 1958). Habitat: montane forest (studied specimen) and semi-rainforest, under leaf litter (Kraus 1958). Collected together with E. ottokrausi sp. nov.
Remarks
The studied specimen, which is a near-topotype, agrees completely with the original description (Kraus 1958); a side-by-side comparison with the holotype was therefore deemed unnecessary.
