from Mt. Nimba, 10 workers

Santschi's (1915c) description is -
WORKER - TL 2.2 mm; head oval. Eyes quite large, set a little forward
of midline. Clypeus convex (less so than lepida),
subcarinate, anterior border weakly but quite broadly scalloped
medially. Mandibles smooth with sparse puncturations; 6 teeth, the
third very small (albipes has four teeth). Scape
surpassing occiput by more than half its length. Thorax somewhat
elongated; pronotum wider than long, very rounded dorso-laterally;
mesonotum as long as anterior width, feebly raised posteriorly;
metanotum a little wider than long, with the spiracles quite close and
raised dorsally. Propodeum convex and very elevated; dorsum shorter
than the declivity. Petiole scale very obliquely angled forward, summit
feebly convex and wider than the base.
Colour clear red
brown; gaster darker; funiculus, tibia and hind femora clear yellow.
Smooth with front of head feebly reticulate. Shiny. Moderately
abundant, brown, quite sharp, erect hairs; four pairs of macrochaets on
alitrunk; metanotum and propodeum without hairs. Pubescence scarce
except on antennae.
Holotype worker only from San
Hawkes & Fisher (2011: 12) place arlesi

(1952) description translated is:
WORKER - TL 2.8-3.1 mm; forebody brown, varying in
darkness, gaster blackish, appendages clear brown. All shiny, without
puncturation except on the propodeum which is finely puncturated on the
dorsum and sides. Strong pilosity, made up of large brown erect hairs,
over all the body; pubescence yellowish, fine and sparse.
Placed in subgenus Nylanderia Emery, by Bernard,
regarded it as in a group with other members known from Cameroun to
Gabon. The others were P. grisoni Forel (type
location Zaïre, with subspecies fuscula
Menozzi, from Fernando Po), P. incallida Santschi
(type location San Thomé I.), and lepida
Santschi; but all three were smaller (TL 2.0-2.4 mm) and had an
elongated propodeum, with a smooth propodeum. With arlesi
the propodeum was broader than long, very enlarged towards the
posterior, with two clear ridges toward the centre. In profile arlesi
was steeply declined, being level or only slightly declined in the
others. Other than the clear distinctions of the posterior shape of the
thorax, arlesi had similar characters to incallida.
Bernard dedicated the species to M. C. Arlès, artist from
his laboratory who mounted and photographed many of the ants from

Specimen used by LaPolla, Hawkes & Fisher (2012) to
illustrate the species.
description of arlesi
given by Bernard (see below) has the colour as more or less dark brown,
gaster blackish, appendages light brown, pilosity of large brown hairs;
TL 2.8-3.1; LaPolla, Hawkes & Fisher (2011) state Bernard's
type specimens "match the [incallida]
type specimens very well" but the two descriptions do not gel. The
description and the CASENT specimen, together with those I show above,
and the LaPolla et al modern
version do match.
