Translation by Hauke Koch - Worker. TL 3.5-3.6 mm. Brown or more red
brown, petiole and abdomen more or less yellowish-brown, the mandibles
and the funiculi dirty-yellowish-red, the tarsi clayish-yellow. The
erect, moderately long pilosity is very sparse on the dorsum, on the
ventrum more pronounced, the scape, the femur (besides some long hairs
at the base) and the tibia have the same hairs; the short close-fitting
pubescence is rather sparse, richer on the tibiae and the scape, on the
latter also somewhat longer and slightly erect. The shiny mandibles are
finely and shallowly longitudinally striated, partly smooth, with few
points, at the base denser and sharper striated. The head is
rounded-quadratic, wider than the thorax, not very shiny, densely and
finely longitudinal, at the distal part transversely striated, with
sparse points bearing a hair, the middle of the frons and the following
median part of the vertex rather shiny and more or less smooth or
slightly streaky. The frontal clypeal margin is not depressed. The
frontal carinae weakly developed. The scape of the 11-segmented antennae
almost but not quite reaching the occipital margin, the 2-4th funicular
joint slightly longer than wide, the 5-7th very conspiciously longer
than wide, the last three joints forming a conspicious club. The eyes
lie in the middle of the sides of the head. The not very shiny alitrunk
is finely longitudinally striated, the sides of the pronotum are more
shiny, particularly below, and more or less smoothened, the declining
area of the propodeum is very shiny and smooth. The alitrunk is rather
short, rounded at the front and very conspiciously wider at the back,
between mesonotum and propodeum very constricted. The pronotum to both
sides with a not very conspicious rounded hump. The mesonotum with a
very conspicious weakly convex disc without median keel, laterally not
emarginated, from the pro-mesonotal suture to the metanotal suture
rather evenly arched. The spines of the propodeum are straight, rather
divergent, circa half as long as the width of the basal area
posteriorly. The shiny pedicel has a very subtle wrinkled sculpture, the
petiole is almost quadratic, insignificantly longer than wide,
anteriorly rounded to both sides, posteriorly truncated, the lateral
margins arched, the maximal width of the segments is in or in front of
their middle; the postpetiole has a moderately sharp longitudinal
groove. The shiny gaster with very subtle shagreening or scaly and with
sparse, hair-bearing points. In the species-overview of the workers of
the African species in my work "Afrikanische Formiciden" in
the "Annalen des k. k. naturhistorischen Hofmuseums in Wien"
1895 page 137, when determining this new species, one gets to No 13a.
These species have a reverse trapezoid petiole, in which the frontal
margin proceeds to both sides, laterally from the with the thorax
articulating, small peduncle, in a more or less transverse direction,
whereas in the new species the frontal margin proceeds to both sides,
laterally from the small peduncle, immediately inclined to the back and
sides and proceeding into the lateral margin. |
