{Anochetus katonae}Forel's (1907a) brief description is at {original description}, his comparisons were with An. grandidieri, from Madagascar (Forel 1891b). Santschi's (1914d) descriptions of occidentalis, parvus and longiceps are at {original description}. Santschi's (1914e) description of punctatus is at {original description}. Arnold (1915) provided a translation of Santschi's (1914e) description of punctatus and notes on durbanensis; these are at {original description}. Santschi's (1920b) description of concinnus is at {original description}. Bernard's (1952) illustrated descriptions of lamottei and gnomulus are at {original description}. Brown's (1978c: 557) illustrated description is at {original description}.


{Anochetus katonae}Nigeria specimens (as Anochetus punctatus, Taylor, 1976: 15). WORKER. TL 3.30 mm, HL 0.75, HW 0.68, SL 0.59 and PW 0.44
Colour castaneous, head lighter, legs and mandibles yellow, shiny. Head sparsely punctate. Alitrunk smooth except for faint rugae on the propodeum, all over with a faint pubescence. Petiolar node a scale with an ovoid apex. Eyes small, length 0.08 mm.
Collected from leaf litter at the Cocoa Research Institute of Nigeria, Idi Ayunre, by B. Bolton.


Differentiated but poorly described, except for illustrations, by Brown (1978, Figs. 12 and 18). Apparently a quite variable form, hence the several synonyms. Variations (following notes by Bernard, 1952) include the size and acuteness of the epinotal teeth, variation in the petiole from somewhat rounded to shallowly bifid dorsally, degree and strength of the pilosity.

Bernard (1952) recorded it from Guinea, as Anochetus gnomulus - workers from "Nimba (Lamotte)"; one worker from station B2 41, ravine of Mount Tô, forest (Lamotte, 21.ii.1942); plus as Anochetus lamottei - 2 workers and 1 head, from savanna at Kéoulenta (22.iii.1942, Lamotte).

Found in Ghana cocoa leaf litter and nesting in dead wood on the ground at the Mampong Cemetery farm (Room, 1971). Collected by Belshaw & Bolton (1994b), who described it as widespread (568 workers from 17 sites) in their leaf litter samples (plus 70 workers from soil samples) from the semi-deciduous forest zone.
