Pseudolasius weissi Santschi
Type location Congo (Santschi, 1910c: 391, illustrated,
worker & queen), collected at Brazzaville, by A. Weiss; also
subspecies sordidus (Santschi, 1914d: 378, worker;
Wheeler, 1922: 219, illustrated, queen) from Ghana,
collected at Aburi by F. Silvestri, in 1913; ); worker and queen
described (see Bolton, 1995)
 .
The major, TL around 3 mm, has a large heart-shaped head; the
minor, TL perhaps 2.5 mm, head being much less indented
posteriorly and straight-sided; the major thorax also is markedly
humped (Wheeler, 1922).
Santschi's (1910c) description is on
 .
Santschi (1914d) noted sordidus as being dull yellow as
opposed to orange yellow for the type, mandibles with 7 teeth,
eyeless, scape just surpassing the occiput and mesonotum profile
flatter, otherwise as type.
Wheeler (1922) listed a finding of sordidus from Akenge,
Zaïre, by Lang & Chapin, all specimens taken from
the stomachs of toads. Santschi (1935) recorded 2 workers from
Wombali, Zaïre, by P. Vanderijst, 9.vii.1923, as being close
to weissi but with the head with stronger rugae.
Bernard (1952) recorded numerous eyeless workers, of variety "sordida",
were found among scrub at the Nion crest, 1300 m, in Guinea.
