Solenopsis ugandensis Santschi

Type location Uganda (Solenopsis ugandensis n. sp., Santschi, 1933b: 102, worker) Kidongou, 11.v.1922, T Bakin - see below
subspecies congolensis (Solenopsis ugandensis Santschi stirps congolensis n. st., Santschi, 1935a: 263) from Zaïre, Luebo, 15.xii.1921, Dr Schouteden - see below
workers only described (see Bolton, 1995) .

Santschi's (1933b) description is at .

Santschi's (1935) description of congolensis is as follows (my translation), comparisons with type form -
Worker - TL 1.3-1.4 mm. Colour clear yellow; sculpturation similar, i.e. smooth except for fine reticulation giving a matt appearance to alitrunk. Head bigger and longer, anterior clypeal border simply arcuate, with denticules hardly distinct and well spaced. Antenna more slender, funiculus segments 3-6 twice as long as wide (marginally more so than type). Petiole pedicel longer and summit wider; postpetiole longer than high; node in dorsal view, appears rectangular, one-third wider than long and larger anteriorly (straighter in front and at least a quarter wider than long in type); sides more rounded. Otherwise as with type except more robust.

The type minor workers (below) appear identical and, thus, congolensis could be regarded as a junior synonym.

Nigeria specimens (as Solenopsis species 1, Taylor, 1980a: 43).
WORKER. TL 1.40 mm, HL 0.34, HW 0.34, SL 0.25, PW 0.22
Colour golden yellow. Sculpturation restricted to reticulation of the propodeum, lower lateral mesonotum and petiole. Eye small. Propodeum an uninterrupted curve from metanotal groove to base. Erect hairs fine, moderately long and abundant, semiprone on the head; a few long erect hairs on the dorsal pronotum. This is a close match for Solenopsis ugandensis, as described for ssp congolensis by Santschi (1935).
