tenuisculptus group overview

This group is monotypic, with the nominal Temnothorax tenuisculptus being the only member. The range of this species as we currently understand it is small, restricted to the low elevations of the Southern Sierra Madre and Los Tuxtlas in southern Mexico (Fig. 169H). It is morphologically similar to the members of the augusti group and is contained within its geographical range. Unlike the members of the augusti group, the petiolar node of T. tenuisculptus is erect, not leaning posteriorly. This species is sister to the annexus group (Prebus, in prep.).
