Lepisiota ambigua (Santschi)
Type location Zaïre (Acantholepis
ambigua n. sp., Santschi, 1935a: 270, illustrated, holotype
worker), collected by L. Burgeon at Ituri, La Moto: Madyu: worker only
Santschi's (1935a) description is on .
description - Worker TL 2.5 mm; dark red brown;
mesonotum and petiole scale more translucent; mandibles and
articulations of tarsi yellow brown; gaster black. Matt, densely and
finely reticulo-punctate; gaster smooth and shiny. Totally without
erect hairs, except the posterior of the gaster with numerous brown
hairs which are slender and almost as long as the width of the legs.
Whole body covered with very fine short pubescence.
Head a rounded rectangle, narrower anteriorly, a little
longer than wide. Clypeus with a strong but diffuse medial carina.
Mandibles smooth, when closed no more than two teeth visible under the
clypeus. Postclypeal notch slightly indicated, frontal area matt and
wider than long; frontal carinae sinuous and near parallel. Eyes
occupying the median third of the face. (Antennae missing) Thorax
narrower than the head but pronotum as wide as long and sides very
rounded; meso-metanotum one-fourth longer than wide; propodeum dorsum
wider than long, teeth reduced; declivity near perpendicular with
almost a right angle from the dorsum. Petiole scale much higher than
pedicel, armed with two fine spines, longer than the basal separation
and curved backwards.
Related to Lepisiota spinosior Forel (type
location Zimbabwe) but that has finer sculpturation, the pronotum more
impressed dorsally, dorsum of propodeum more concave, angles with more
pronounced teeth and the petiole scale with longer spines.
Santschi (1935) described it as in a small group with spinosior
the latter being darker, near black and somewhat smaller. It also
appears to be similar to the specimens I drew and labelled as "species
Bolton collected" below.
