Paratrechina waelbroecki (Emery)
Type location Zaïre (Prenolepis
waelbroecki, Emery, 1899e: 496, illustrated, male genitalia, male
and female described) from Kinshasa, collected by Waelbroeck,
x-xi.1896 - male type see below. Forel (1911f: 280) reported "Prenolepis
Emery worker (??) - Congo da Lemba : MAYNÉ (Musée du Congo)"; also from
Congo da Lemba by A. Weiss (Wheeler, 1922: 943). .

described the queen of P. waelbroecki as ferruginous brown,
with a darker gaster; the propodeum arcing from the dorsum into a near
vertical declivity. The main negative for this association is Emery's
comment that the queen had a very shiny dorsum to the alitrunk. Emery
noted the male approached the "new species P. longicornis".
Forel (1916: 440) suggested that the workers he
described as Paratrechina
grisoni actually might be the asexual form of waelbroecki.
However, the grisoni worker is very shiny overall, a lot
smaller (TL ca 2.0 mm), and has no pubescence.
This queen appears to be a good match to the
Hawkes & Fisher (2012: 23) write on this
species but, despite giving "Emery, 1899: 496 (queen and male
described), note they could not locate any worker specimens from the
Forel (1911) report, and state "The queen caste is currently unknown
for this species".
A male is shown from http://www.antweb.org/specimen.do?name=usnment00693679&shot=h1&project=worldants
from the usual sexual differences for the genus, the male being
somewhat smaller and more slender there is nothing to suggest the queen
I report is not that of the species.
is of a possible worker from the Congo,
Lesio-Louna, collector Eric Zassi (12-t-1). The general colour, median
carina on the clypeus and gaster pubescence are as on the male above
but the scapes do not appear to bear any erect hairs.
