Tetraponera ledouxi Terron
Type location Cameroun (Terron, 1969: 269, illustrated,
all forms); all forms described (see Bolton, 1995)
.
Terron's (1969) description is at
,
and .
In brief - Terron, who dedicated the species to Professor
Ledoux, reported it as coming from the Yaoundé Region
(without any specific details, indeed he appears not to have
designated a holotype), and described it as a temporary parasite
of Tetraponera anthracina Santschi, the most common
Promyrmicine in the region. He gave full descriptions of all the
castes but I am restricting this to the worker -
WORKER - TL 7.1-7.68-7.9 mm (21 individuals); SL 0.81
Colour black, with extremities brown; cuticle smooth and not
finely puncturate as in anthracina; whitish pubescence on
all the body; on the head and thorax less dense but longer than on
anthracina. Erect hairs, one at at the extremity of each
frontal carina and 3-5 behind; one on the base, one on the middle
and one at the end of the scape; one on the first funiculus
segment; on anterior border of clypeus, incurved; small hairs on
the internal surface of the mandible; two on each side of the
pronotum; two dorsal on the petiole; numerous on the gaster. Head
1.05-1.20 times as long as wide; widest at the level of the eyes,
vertex and gulae a little more rounded than anthracina;
posterior angles rounded, occipital border straight or subconvex;
clypeus very short, rectilinear, slightly emarginate in the median
area (crenellated in anthracina). Mandibles shorter and
more slender than in anthracina. Eyes large, almost half
the length of the head, set in mostly in the posterior half of the
head; two small ocelli, set a little behind the level of the
posterior of the eyes. Antennae short, inserted very close to the
clypeus; first and last segments of funiculus longer than wider,
no club.
Thorax similar in length and height to anthracina but
slightly narrower and higher. Propodeum bordered laterally by a
carina that is less pronounced than in anthracina, rounded
towards the posterior, declivity as in anthracina.
Petiole longer and higher than anthracina, postpetiole
convex dorsally and ventrally without carinae.
Possibly the same as
Tetraponera
triangularis type or perhaps ssp illota. |
