Cataulacus kenyensis Santschi
Type location Kenya (Cataulacus
Jeanneli Sants. stirps kenyensis nov., Santschi, 1935b:
worker; junior synonym of weissi in Bolton, 1974a: 39; revived
from synonymy and raised to species Bolton, 1982: 358) .
(1935b) description is at .
WORKER - TL 3.6 mm (Bolton, 1982: 358, not illustrated,
and not described).
Key separation note - stout hairs on cephalic dorsum
sparse, not giving appearnce of a bristly pelt (cf Cataulacus cestus); line across
dorsum of head at midlength with no more than 10 hairs; hairs on dorsum
of head conspicuously spatulate, broadly convex apically, their sides
shallowly convex and convergent basally.
WORKER - TL 2.74-3.08 mm, HL 0.85, HW 0.85, SL ca 0.4,
The photomontage is of a worker from Tanzania,
Mkomazi Game Reserve; collector G C McGavin (Tree 5-17).
In general form somewhat similar to Cataulacus cestus
but head covered in stud-like hairs and not very short erect bristles.
In full-face view the head is uniquely square, albeit with weakly
convex sides; when tilted slightly backwards the shape is broadly
ovoid, even the clypeal margin being weakly convex. Very distinctive
sculpturation and large eyes. Occipital corners of head and sides of
head behind the eyes without denticles. Dorsum of head strongly
reticulate with no rugosity. Alitrunk dorsum weakly rugose,
longitudinal on top of the pronotum, rugae running obliquely on the
lateral alitrunk. Dorsal and lateral surfaces of petiole and
postpetiole are longitudinally rugose. Femora also strongly
longitudinally rugose. Hairs on all dorsal surfaces numerous,
progressively shorter and stouter anteriorly, those on anterior of
cephalic dorsum, especially the clypeus, strongly clavate. Pronotum is
strongly marginate, with the humeral angles with a very small
triangular tooth; margination with minute denticles no more than the
bases of the minute erect hairs, terminating posteriorly in a single
larger denticle close to the promesonotal junction. Mesonotum and
propodeum not marginate but with a few minute denticles. Propodeal
spines moderately long elongated triangles and angled upwards
Apparently commensal with Crematogaster mimosae
on Trees 5/17 and 5/26, Acacia zanzibarica; the same trees also
had numbers of Tetraponera bifoveolata.
