Fig. 17 View Fig. 17


Differs from other species of the E. kwabuniense group by having a smooth iap much shorter than map and by having the large dorsal lobe of the solenomere bifid.


Named after the type locality, Mt Kalimbasi (Kalimbazi).

Material studied (total: 4 ♂♂)


TANZANIA: ♂, Iringa Region, Iringa District, Kalimbasi Mountain , 2000–2100 m a.s.l., 10 km S of Mazombe (forest floor), Jan. 1984, J. Kielland leg. ( VMNH).


TANZANIA: 3 ♂♂, same collection data as for holotype ( VMNH, ZMUC).

Description (male)

SIZE. Length 19 mm, max. width 1.6 mm.

COLOUR. After 34 years in alcohol completely whitish.

ANTENNAE. Reaching back to end of ring 4.

BODY RINGS. Paranota completely absent. Stricture between pro- and metazonite smooth. A transverse row of setae on all body rings.

HYPROPROCT. Trapezoid, almost reactangular, with three strong marginal tubercles.

LEGS. Length = body width. Relative lengths of podomeres: femur> prefemur (>) tarsus> tibia (>) postfemur. Scopulae well-developed on postfemur, tibia and tarsus all the way to last leg pairs, also weakly on femora of anterior legs.

STERNUM 5. A tongue-shaped process between legs 4.

STERNUM 6. Deeply excavated. Rim of excavation simple.

GONOPODS ( Fig. 17 View Fig. 17 ). Coxal lobe (cxl) moderate. Prefemoral part (prf) ca half as long as acropodite. Mesal acropodital process (map) a straight pointed rod with a small lateral bump ca at ⅔ of its length. Intermediate acropodital process (iap) much shorter than map, slender, straight, pointed, smooth. Solenophore (sph) very large, ca as long as map, apically divided into a bifid dorsal lobe (sph-d), a slender, pointed intermediate lobe (sph-i) and a broader, apically linearly obtuse ventral lobe (sph-v).

Distribution and habitat

Known only from Kalimbasi Mountain, S of Mazombe town, 2000–2100 m a.s.l. The site is located in the Kisinga-Rugaro FR.
