Lepisiota gerardi (Santschi)
Type location Zaïre (Acantholepis gerardi , n.
sp., Santschi, 1915c: 262, worker, not illustrated) collected at
Katanga, Upper Lukuga, Kataki, by Gérard; holotype worker only
.
Santschi's (1915c) description is at
My translation: WORKER. TL 2.5 mm; head a little longer than wide;
rounded up to the eyes; posteriorly without angles; sides of head
slightly convex before the eyes, slightly converging anteriorly.
Mandibles smooth and shiny, partially covered by the clypeus. Clypeus
strongly carinate and convex in profile. Eyes occupying just under the
median third of the head and slightly depressed posteriorly. Scape
surpassing the occiput by about one-third of its length; funiculus
segment 1 one and a half times the length of those following, and
twice as long as wide. Pronotum depressed in a transverse oval;
anterior 5/6 with blunt raised borders giving a strongly concave
transverse profile. Meso-metanotum as waisted as in frauenfeldi
(European) and almost as long; spiracles much more raised into
conical prominences. Propodeum with robust lateral lobes, raised and
diverging to give elongated, but rounded cones, as long as the half
the basal separation. Petiole scale very high, inclined backwards and
very narrow at the summit; that terminating in two spines as little
longer than the interval between them; posterior pedicel shorter than
the height of the scale. Gaster rounded.
Colour black; appendages brown, except apical part of scapes and
tibiae which are darker brown. Overall dull matt; dorsum of head and
pronotum, plus gaster shiny and smooth. Front of head feebly
reticulated; rest densely and very finely reticulo-striate
longitudinally. Mesothorax mostly fairly strongly longitudinally
striate/rugose. Propodeal declivity finely tranversely striate. Some
long silky black hairs dispersed on the body, mainly on the gaster.
Sparse fine white and short pubescence, rare on the gaster.
Close to depressa Santschi (from Kenya) and deplanata
from Tanzania, in having the concave pronotum, but separable by its
elongated mesonotum and the petiole scale.

Nigeria specimens (as Acantholepis spinosior, Taylor, 1978: 37). WORKER. TL 2.43 mm, HL 0.65, HW 0.59, SL 0.76, PW 0.40
Colour black or dark red-brown, extremities lighter. Appearance dull
because of an overall sculpturation of fine spiculation. Erect coarse,
dark brown hairs moderately abundant on the body but sparse on the
head. Propodeal prominences spinose. Petiole spines well developed and
curving backwards. Occasionally seen foraging on cocoa and will tend
aphids; also found on coffee.
Also found in Ghana, as Acantholepis spinosior Forel
(type location Zimbabwe, see Bolton, 1995), throughout the Mampong
Cemetery Farm by Room (1971). Twenty-four workers were collected on
the ground from a block of mature Amelonado cocoa at CRIG by Bigger
(1981a). |
