Temnothorax fuscatus (Mann, 1920)

Prebus, Matthew M., 2021, Taxonomic revision of the Temnothorax salvini clade (Hymenoptera: Formicidae), with a key to the clades of New World Temnothorax, PeerJ (e 11514) 9, pp. 1-462 : 148

fuscatus group overview

With four species (one described as new here), the fuscatus group is another small group with a range spanning the mid-to-high elevations of central Mexico to southern Central America ( Fig. 107 ). All nest collections of fuscatus group species have been from arboreal habitats, either nesting in vegetation (alive or dead) on live trees or in epiphytes. The low, long petiolar node distinguishes this group from nearly everything else in the salvini clade. Apparently, the fuscatus group is sister to the ground-nesting pergandei group (Prebus, in prep.).

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, non-type localities are represented by circles. Bounding box in inset map shows location of main map. Full-size DOI: 10.7717/peerj.11514/fig-107
