{Messor+regalis}Emery's (1892d) description is at {original description}. Santschi's (1913c) description of the worker and of rubea is at {original description}; his (1920d) placement of Cratomyrmex as a subgenus of Messor is at {original description}. Stizt's (1916) description of sculpturatus is at {original description}. Bolton's modern description (1982) is at {original description}.

{Messor regalis sculpturatus}WORKER - HW 3.0 (medium) - > 4.5 (Bolton, 1982: 352, not illustrated). TL ca 6-14 mm (J-m K). Dorsum of propodeum without standing hairs; sides of head with projecting hairs in full-face view; petiole and postpetiole coarsely, closely and deeply rugose.

In Bolton (1982) the reason for the type location confusion is revealed as his denotation of a lectotype female from Benue, Nigeria (collector Staudinger, no date, also in Wheeler, 1922). Bolton fails to cite Santschi (1913c) as the descriptor of the type worker, noting only the additional description of rubea; other Nigeria collections were N. Bussa, Kano State (J.T. Medler), Mokwa (C. Longhurst), and Olokemeji (Bridwell). Wheeler (1922) also listed Nigeria collections at Lagos and Olokemeji (F. Silvestri); plus Benin (Aguagua, by Roubaud).

Wheeler (1922) also had sculpturatus from Falls of the Nana River near Fort Crampel, "Congo" = Central African Republic, by Haberer.

Lévieux & Diomande (1982) reported findings on its food sources in Ivory Coast, where it is a species of the Sudan savannah in the north of the country. It forages over an area of 1300-1400 m² from the nest, is diurnally active with morning and evening peaks, prefers covered ground, and mostly utilises a tall grass species for its food.
