Tetramorium pullulum Santschi

Type location Zaïre (Tetramorium guineense F. stirps pullulum n. st., Santschi, 1924b: 211, illustrated, worker; but what must be the same specimen named as Xiphomyrmex uelense by Santschi, 1935: 267; raised to species by Bolton, 1980: 273, not illustrated) collected at Haut Uelé, by L. Burgeon; junior synonym fernandensis (Menozzi, 1942: 174, illustrated) from Fernando Po I., Moke, by H. Eidmann, xii.1939; worker only described (see Bolton, 1995). Bolton (1980) does not comment on this aberration of naming, and Santschi (1935) describes the specimen without any hint of having seen it previously .

WORKER - TL 3.2-4.0 mm. Santschi's (1935) description was - black, mandibles, antennae and tarsi brownish; anterior of tibiae whitish. Area between frontal carinae stretching back to the posterior angles of the head with five strong and spaced rugae, the median three arising on the clypeus; the outer two close to the frontal carinae. irregularly reticulate between the rugae; on the vertex a strong ruga or transverse fold crosses from one frontal carina to the other. The scape is smooth to the midpoint and then more or less reticulated. The rugae of the head pass on to the dorsum of the thorax and pedicel, somewhat more irregular and with spaces smooth. Between the pro and mesonotum there is a strong transverse ridge; the centre of the mesonotum and the sides of the thorax have clear spaces. The postpetiole is more feebly scupltured than the petiole, and the gaster is shiny with microscopic longitudinal rugulae. Pilosity erect, brownish, quite long and abundant on the body; appendages with long decumbent pubescence.
Head rectangular, about one-fifth long than wide, anterior angles dentate or sharp. Clypeus concave medially. Mandibles smooth, with three apical teeth. The convex eyes occupy the median third of the head. Scape reaching the occiput; mid-segments of funiculus transverse; basal two segments of club slightly longer than wide but apical segment as long as the other two together. Thorax straighter than head; pronotum flat after the transverse ridge and mesonotum horizontal in profile; propodeum dorsum oblique, spines robust, slightly divergent, raised and slightly curved upwards; metasternal spines shorter. Petiole node rectangular in profile, as high as long; postpetiole node also as wide as long but about one-third larger than the petiole node; posterior articulation thick. Gaster as long as the thorax.

Bolton (1980) reported other specimens from Zaïre, Sudan, Uganda and Angola.
