Euponera sjostedti (Mayr)
Type location Cameroun
nov. spec., Mayr 1896: 231, worker; Santschi,
queen; new status Schmidt & Shattuck, 2014: 87) collected from a
dead palm stump by Y. Sjöstedt - see below
queen described (see Bolton, 1995) .
Mayr's (1896) descriptions are at . and, for the sexual stages, . Santschi's (1914d) description of the
queen is at .
Wheeler (1922, illustrated, full profile and full-face
head) had other Cameroun records from Victoria (F. Silvestri)
and Mbalmajo to Ekeneli (G. Schwab); plus a Zaïre finding, where they
were nesting in or under rotting palm trunks.
Also found in Ghana cocoa, foraging and nesting
in dead wood on the ground at the Mampong Cemetery farm (Room, 1971).
Nigeria specimens (as Bothroponera
Taylor, 1976: 41). WORKER. TL 6.84 mm, HL 1.12, HW 1.00, SL 0.75, PW
Colour red-brown. All over reticulopunctate, dense and fairly coarse,
except on posterior face of the propodeum which is smooth and shiny.
Pilosity short and dense, tending to obscure sculpturation. Erect hairs
moderately long and relatively abundant. Eye very small, recessed into
head fairly close to the anterior margin. Mandibles with a distinct
basal dorsolateral fovea. Propodeum distinctly marginate laterally.
Wheeler (1922) regarded the small size (for Ponerines), pale
colouration and eyes reduced to a few ommatidia as distinctive. I found
it under a rotting log with termites.

I collected this photomontage from the Antweb site at http://www.antweb.org/specimen.do?name=sam-hym-c007972 (posted 17.ix.2009).
As can be seen it is labelled "Pachycondyla testacea" and
identified by W L Brown.
testacea, now Mesoponera testacea, however is known solely from the Bernard (1952)
description of a single worker. That is a typical Mesoponera (Xiphopelta)
with long mandibles and small eyes set some distance back from the
anterior margin of the head. Moreover, it is a shiny species with
Few Xiphopelta queens have been described and
ambigua is shown in an image. That I repeat below. As described
for the subgenus queens, it differs little from the known workers with
long mandibles and only moderate sized eyes set back from the anterior
This Brown identified queen clearly is not the queen of testacea.
The wing venation is similar to that of ambigua and, at least,
places the species in Pachycondyla. Two features might place it
in Xiphopelta - the long first funiculus segment and the median
tooth on the anterior margin of the clypeus.
Now, June 2014, it appears as Parvoponera darwinii madecassa.
Mayr has the sjostedti queen as TL 5.3 mm. The
colour of the Ivory Coast queen seems paler than the Cameroun type
forms but the overall features are a good match for the description and
the later Santschi drawing.
