Platythyrea occidentalis André
Type location Sierra
Leone (Platythyrea occidentalis
n. sp., André, 1890: 315, queen; André, 1895a: 3, male; worker by
Arnold, 1954: 291, illustrated, worker) location not given, collected
by Mocquerys - see the type dealate queen at http://www.antweb.org/specimenImages.do?code=casent0913731
all forms described (see Bolton, 1995) .
description of the queen is at . André's (1895a) description of the male
is at . Wheeler (1922) listed it also from Congo.
Arnold (1954) gave an illustration and his description of the
worker (from Uganda) is at .
A. Mocquerys collected at 'Riv.N' Gamie, Chûtes de Samlia (Atopomyrmex
cryptoceroides, in Mayr 1895 & Bolton, 1981b).
Brown (1975: 46) noted
that specimens collected at Tafo, Ghana, by D Leston, were
reddish brown in colour, HL 1.40, with the eyes no wider than 0.14
whereas the scape width was 0.23 mm. The very long second funiculus
segment is diagnostic; together with a deep subrectangular excision at
the top of the propodeal declivity. He claimed the type specimen from
Sierra Leone was a dealate queen and ferruginous in colour, with the
characteristic three petiolar teeth.

photomontage is of a worker from Liberia,
Liabala; collector E Poiriet (Liabala PF 6).

collated from http://www.antweb.org/specimenImages.do?name=sam-ent-0011507
While this clearly is the worker described by Arnold
(1954), note he gave the colour as "black", with the appendages
brownish red, it differs in several ways from the fresh worker shown
TL ca 7.6 mm (Arnold 7.0 mm) HW 1.35 HL 1.6 SL 1.1 PW
09.5 EL 0.2. Head relatively shorter and with weakly convex
sides; petiole also with more convex sides in dorsal view but
flat-tooped rather than shallowly domed. With more specimens it
seems likely that Arnold described the worker of a distinct species
separate from occidentalis.
