{Serrastruma lujae calypso}WORKER - TL 2.2-3.3 mm; characters as in key; note variable size; colour yellow to medium-brown (Bolton, 1983, illustrated, alitrunk and pedicel profile).

A mainly forest species found throughout sub-Saharan Africa, with many records (Bolton, 1983).

Brown (1952) also reported specimens as found in Honolulu (Hawaiian Plant Quarantine) and Saő Tomé.

Specimens in the CRIN collection were labelled as from CRI, Ghana, although Bolton (1983) noted that he collected it in Nigeria, at CRIN.

From Ghana, at CRIG (C.A. Collingwood; B. Bolton), Aburi and Mamfe Scarp (D. Leston), and Bolgatanga (E.S. Ross & K. Lorenzen) (Bolton, 1983). Found on cocoa at Kade by Majer (1975); from cocoa mistletoe (Room, 1975). Since collected from leaf litter (802 workers) in the semi-deciduous forest zone, under cocoa at Juaso, primary forest at Esukawkaw Forest Reserve and Atewa Forest Reserve, by Belshaw & Bolton (1994b).

From Ivory Coast in Banco Forest (I. Löbl; W.L. Brown), at Man (I. Löbl; V. Mahnert & J.-L. Perret), at Yapo Forest, Agboville (I. Löbl), Anguédédou Forest (W.L. Brown) and Sangrobo (W.L. & D.E. Brown).

Cameroun records include Batanga (G. Schwab), Mt. Cameroun (L. Fea, perhaps in 1901; B. Malkin), Nko'emvon (D.A. Jackson) and near Yaoundé (G. Terron).

Bernard (1952) recorded a Guinea, finding of a single worker (as Strumigenys (Cephaloxys) glanduscula) from Mt. Nimba, Nion, 700 m; "different from the type (Belgian Congo) by being shorter and with the spines twice as long". He separated it from a specimen of bequaerti (see above).

Nests in dead wood on living trees, foraging there and in leaf litter. Bolton (1983) relates a letter from W.L. Brown, in which the habit of preying on collembolans was vividly described, no other insects were seen as prey. Déjean & Benhamou (1993) described how the workers search individually for collembolans in the leaf litter of humid tropical forests. The core of their paper was a laboratory study of the orientation and foraging movements in a patchy environment, similar to that found in the dry season in the forests, when collembolans congregate in wet patches of leaf litter.
