Fig 9 View Fig. 9

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). GoogleMaps

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 View 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 View Fig. 9 ). 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.
