return to group key {link to the Hymenoptera Name Server} Type location Cameroun (Tetramorium (Xiphomyrmex) Muralti, n.sp., Forel, 1910e: 429, worker; Santschi, 1914d: 368, queen, from Aburi, Ghana), no location, collected by L. von Muralt
junior synonym trilineata from Ghana (Xiphomyrmex Muralti For. var. trilineata n. var., Santschi, 1919h: 88, worker & queen) collected at Aburi by F. Silvestri - queen see below
worker & queen described (see Bolton, 1995) .


Forel's (1910e) description is at {original description}. Santschi's (1914d) description is at {original description}. Santschi's (1919h) description of trilineata is at {original description}. Bolton's modern description (1980) is at {original description}.


WORKER - TL 2.77 mm; specimens from Ghana cocoa but not drawn (in my guide as Xiphomyrmex species A). Bolton (1980: 229, not illustrated) has TL 2.1-2.3.
Brown, shiny and unsculptured. Head with distinct antennal scrobes; also medial dorsal longitudinal carinae which run the full length of the head plus two shorter carinae, one on each side, which are between the medial and frontal carinae. The pedicel segments are thick scales.

I could not definitely match these specimens with any in Bolton (1980, not illustrated) but two workers were collected from the ground at CRIG by Bigger (1981a). Bolton (1980) had it as a forest-inhabiting species which nests in rotten wood in the leaf-litter, with findings from Ghana, at Mampong (P.M. Room) and Kukurantumi (C.A. Collingwood). Since described as widespread (189 workers from 10 sites) in leaf litter by Belshaw & Bolton (1994b).

An Ivory Coast finding, at Banco Forest (W.L. Brown) and Divo (C.A. Collingwood); also known from Zare (Wheeler, 1922). Bernard (1952) listed four workers (as X. muralti) from Guinea at Nimba North-East, forest (Villiers).

This is a good match for the Santschi (1914d) description, including the large postpetiole, equal in size to the petiole.
