Tetramorium nautarum (Santschi)

Type location Annobon I. (Tetramorium caespitum st nautarum, Santschi, 1918c: 156, worker; raised to species by Bolton, 1980) .

Santschi's (1918c) description is at . Bolton (1980) gave no description of nautarum commenting that it may be no more than a synonym of one of the European members of the caespitum-group.

From Santschi's description and the photomontage, I agree with Bolton that nautarum seems to differ little if at all from the caespitum type form.

The photomontage is collated from http://www.antweb.org/specimen.do?name=casent0005827&shot=p1&project= Locality: U.S.A.: California: Yolo; Davis, CA; 38°33'00"N 121°45'00"W 15m
