Asphinctopone lucidus Weber
Type location Central African Republic (Weber, 1949b: 7,
illustrated, worker); worker only described (see Bolton, 1995, who
spells it as lucida)
.
Weber's description (1949b) is at .
WORKER (updated by me): Extended length 3.5 mm; of thorax (including neck) 1.1 mm.
Head in front view, excluding mandibles, one and one-fifth times
longer than broad, occipital margin feebly convex, corners broadly
rounded, sides feebly convex; clypeus with a median carina which
projects slightly over the anterior margin, the latter otherwise
slightly concave medially and produced laterally on each side as an
obtuse angle which projects over the cutting margin of the mandibles;
frontal lobes fused, flat, short, and convex; eyes about 0.04 mm. in
diameter, situated at the sides about four of their diameters from the
base of the mandibles; mandibles narrow, triangular, evenly convex on
their lateral margins, with five or six teeth exposed beyond the
clypeal lobe; antennal scapes distinctly exceeding occipital angles,
slender, slightly enlarged distally, slightly longer than the
funiculus to the terminal segment, funiculus with three-segmented club
equal in length to the preceding seven taken together. Thorax from
above with well-developed neck, behind which the pronotum rises as an
even convexity and is broader than the remainder of the thorax:
mesonotum small and transversely elliptical, well marked from the
pronotum and propodeum: metanotal groove deep, propodeum with sides
flattish and converging up to the basal surface, declivity plane and
marginate at the side; thorax in side view forming one general arc
interrupted by promesonotal and a much deeper metanotal impression,
the propdeum declivity surface being flattened. Petiolar node high and
scale-like, in side view with sides converging to a narrow, convex
apex; viewed from in front the scale has convex sides broadest above
the middle and a slightly angulate convex apex. Gaster from above
elongate-ovate, evenly convex anteriorly first and second segments
approximately equal in length and forming about two-thirds of the
gaster; sting of moderate dimensions and exserted. Legs long and
slender, of moderate proportions.
Shining; head densely and finely, thorax and especially propodeum
more sparsely but coarsely, gaster and appendages except mandibles
finely punctate; mandibles with a few piligerous punctures. Hairs
largely absent except for a dense yellow tuft at the apex of the
gaster; pubescence moderately fine and dense, especially on the
antennae and legs, but sparsely on the gaster.
Uniformly bright ferruginous.
HOLOTYPE: One worker taken March l2, 1948, 5 miles west of Bangassou,
Ubangi-Shari, French Equatorial Africa. The ant was in well-developed
gallery forest extending up a watercourse from the Mbomu River and was
beneath damp leaves on the forest floor.
The genotype, A. silvestrii Santschi, described from Nigeria
in 1914, differs distinctly in having antennal scapes failing to reach
the occiput, the propodeum more steeply declivitous, the petiolar
scale thicker, and in other ways. |
