Lepisiota cacozela (Santschi)

Type location Congo (Acantholepis capensis st canescens var cacozela Santschi, 1914b: 124 in key, worker, 1914d: 378; Acantholepis capensis var. cacozela, Stitz, 1916: 395, worker; raised to species Santschi, 1935a: 270; Bolton, 1995, gives a misleading attribution to Stitz, 1916: 295, who merely used the name when identifying a specimen) .

Santschi's (1914b) description is at . As extracted from key couplets, this is -
WORKER - Petiole scale with a thick profile and only weakly emarginate; alitrunk stocky; base colour black; erect pilosity of whitish, more or less fine, long and abundant hairs; quite shiny; scape with non-erect pubescence, which is shorter on the legs and genae.

Santschi (1935a: 270) had the illustration (right) of the petiole scale and noted how it differed from Lepisiota albata in having a face which narrows anteriorly. From my drawing, etc., the scale shape and general appearance suggests that my Lepisiota species T² (below) may be this species.

Wheeler (1922) listed it from Nigeria, collected at Olokemeji by F. Silvestri; and Zaïre but had it as a variety of Lepisiota canescens, noting that it had longer hairs than the typical canescens and the petiolar scale was thickened at the summit, with scarcely an excised border. Workers were taken from the hollow stem of an unidentified plant.

Lepisiota species T² & Lepisiota species T³

These seem to represent two species; with T² having a single morph (as is typical for the genus) and T³ having a minor morph of similar characters but slightly smaller and a much larger major morph.

T² morph - TL 2.61 mm, HL 0.67, HW 0.62, SL 0.76, PW 0.44
T³ minor - TL 2.36 mm, HL 0.59, HW 0.54, SL 0.67, PW 0.39
T³ major - TL 3.21-3.60 mm, HL 0.90-0.99, HW 0.93-1.14, SL 0.76-0.90, PW 0.53-0.54
(in my guides as Acantholepis species T² and T³ )

Generally black, with lighter extremities, yellow-brown on tarsi, shiny.

T² and T³ minor with abundant long, white erect hairs. Propodeal prominences moderately acute. Petiole a thick almost emarginate scale; suggestive of it being cacozela.

T³ major more massive with a large head which is greater in width than in length. Very abundant long, white erect hairs and long white pilosity on head and alitrunk. Petiole with the dorsal margin straight to slightly concave.

Apart from the curious dimorphism of T³, which seems unusual for the genus, there is a behavioural separation with T² being more common, especially on cocoa in Nigeria, where it can be a sub-dominant, with Crematogaster africana, on 5-10% of trees; and at 53/76 farms (combined result with Lepisiota species, formerly capensis, see above) (Taylor, 1977; Taylor & Adedoyin, 1978). Both forms, however, will tend aphids and coccids, and build tents of vegetable and other debris. Also found foraging on native herbaceous vegetation and trees, and on cashew and kola.
