Forel's (1911c) description is at {original description}. Forel's (1913b) description of gilviventris is at {original description}. Forel's (1914d) report, with descriptions of the queen & male (from Zimbabwe & South Africa) is at {original description}. Arnold (1917: 397) gave a translation, this is at {original description}, with notes on its finding in Zimbabwe.

WORKER - diagnostic characters as per the key.

The species was revived from synonymy with Cataulacus brevisetosus by Bolton (1982: 358, not illustrated). His 1974 description forewarned of this by drawing attention to the wide size range of brevisetosus. However, Bolton (1982) did not describe either C. jeanneli or C. lujae.

Bequaert (1922, p 370) wrote of it (variety gilviventris) as nesting in empty lepidopterous galls on a tree at Kabanza, near Kikondja, Zaïre.

Extrapolating from the earlier brevisetosus list of findings (Bolton, 1974a), the following may be correct, or may include jeanneli.

Possibly, the species found in Ghana cocoa at Akosombo and Domfen (C.A. Collingwood), CRIG (B. Bolton), Mampong, Enchi and Legon (D. Leston) (Bolton, 1974a) and, later, at Kade by Majer (1975, 1976b), using pkd, with some 70 workers per sample, and in 137/144 samples in the main study plot. Curiously, perhaps, not found in any of the 168 samples of insolated canopy collected by Room (1971). Found in small numbers by canopy pkd from both Crematogaster clariventris and Oecophylla longinoda dominated areas of a block of mature Amelonado cocoa at CRIG by Bigger (1981a).

Bolton (1982), without details, has Nigeria, possibly CRIN (B. Bolton) and Araromi (?); and Cameroun (possibly, D.A. Jackson) as further countries from which it is recorded.
