pulchellus group overview

With fifteen species (nine described as new here), the pulchellus group is the largest in the salvini clade. Primarily inhabiting the low elevations of the Caribbean islands and southern Florida, this group has a peculiar bimodal elevational distribution, inhabiting some of the highest points on the island of Hispaniola, but as of yet without any records of mid-elevation collections ( Fig. 133). Nest collections of this group, while rare, suggest nesting habits similar to the pastinifer group, i.e., within dead wood and vegetation on or near the ground, often in leaf litter. The general habitus of the members of the pulchellus group is another example of the Macromischa syndrome, with most species having extremely arched mesosomata, often with enlarged femora, and always with broad postpetioles. These characters broadly overlap with the pastinifer group, Temnothorax subditivus , and some members of the sallei clade (e.g., the sallei and iris subclades sensu Prebus (2017)).
