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

= dorsal, intermediate and ventral lobes of solenophore. Scale bars: 0.1 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
). 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
