pergandei group overview

This group is composed of two species, Temnothorax pergandei and T. bison sp. nov., which are found at all elevations from eastern North America to Central America ( Fig. 127 ). For much of its history, the nominal species of this group was placed in its own subgenus (Dichothorax). All nest collections have been made from soil or dead vegetation on the ground; this appears to be a primarily terrestrial group. United by a strongly depressed propodeum, long setae on all surfaces of the body, and reduced or absent propodeal spines, the members of the pergandei group are unlikely to be confused with any co-occurring Temnothorax species (although they appear to be morphologically convergent with some species of the Mediterranean region of Europe).

Figures

Figure 127 Geographical and elevational distribution of the pergandei group. (A) Temnothorax bison sp. nov. (B) T. pergandei. The colored scale to the left of each map represents elevation in meters. Points in black represent the species named in each subfigure, while points in red represent other members of the species group. Type localities are represented by triangles; if present, types of synonyms are named; non-type localities are represented by circles. Bounding box in inset map shows location of main map.
