Atopomyrmex mocquerysi subspecies cryptoceroides (Emery) ^HNS

Thirteen specimens from Malela (J. Bequaert) are referable to this form, which, I believe with Forel, is to be regarded merely as a subspecies of mocquerysi ^HNS and not as an independent species. It is easily distinguished by its more shining head, coarser thoracic sculpture, and longer, stouter and, in the large workers, basally more flattened epinotal spines. The small workers have the spines slender, more curved, and more backwardly directed, just as in the small individuals of the true mocquerysi ^HNS.

The habits of cryptoceroides ^HNS are evidently the same as those of the typical form, as it had been previously taken by Bequaert at Elisabethville in the Katanga "nesting in the rotten wood of a felled tree."
