Typhlomyrmex foreli 
Typhlomyrmex foreli Santschi, 1924, Ann. Soc. ent. Belg., 64: 6, female. 
Type locality: Rio Negro, Parana, Brazil. Location of type unknown 
(not in Santschi Collection). 
This species was described from a single gyne. I suspect it to be the 
gyne of T. major , but some items in Santschi’s description will leave 
doubts until the type can be re-examined. Probably the “court sillon 
median” on the clypeus can be dismissed as an illusion caused by the 
shiny surface here; I have noticed this in other species. Santschi says 
that the external margins of the mandibles are slightly concave, a 
description that will fit no specimen of any species of Typhlomyrmex 
in full-face view, but will fit all of them if viewed obliquely from 
above and slightly to the side. 
The “bord terminal long, finement denticule avee une dent apicale 
bien developee” would fit the new species prolatus (see above), but 
would also fit T. major reasonably well. 
Santschi’s statement, “The first article of the funiculus is not quite 
as long as the three following ones taken together” fits prolatus fairly 
well, while in a gyne I take to be major, the first funicular segment 
is shorter than this. 
In spite of these difficulties, the like of which often crop up in 
connection with Santschi’s descriptions of ants, I think it probable 
that T. foreli and T. major are conspecific. The distributional 
evidence weighs for this decision, and Santschi mentions no posterior 
concavity of petiole and no median postpetiolar carina such as prolatus 
carries.
