Specimen labels

Synonyms

This species is less arboreal than most Pseudomyrmex, and nests typically in rotten wood on or near the ground. The type specimen of P. boopis came from a nest in a swollen-thorn acacia (Smith 1862:33), however, and Janzen found colonies in thorns of Acacia melanoceras seedlings in Panama (Ward 1993). Gillette et al. (2015) in a Chaipas, Mexico field study of twig-nesting ants in coffee plants found P. boopis nesting within one sampled plot of plants at 1200m.

Pseudomyrma modesta

Holotype worker in Oxford University Museum of Natural History. Labelled “Bac.”

Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.

Description

Ward (1993) - Medium-sized species (HW 1.16-1.29) in the P. tenuis group, with a broad head (CI 0.92-1.02), tectiform and laterally rounded median clypeal lobe, large eyes (REL 0.66), and laterally marginate pronotum. Mesosoma arched and angular in profile; petiole short, high and thin, laterally marginate, with a gently ascending anterodorsal face which rounds into a much steeper (almost vertical) posterior face. Standing pilosity sparse, lacking on the mesonotum, propodeum, and petiole. Color highly variable, ranging from light testaceous brown to bicolored orange and black (usually with the gaster and pronotum lightest in color) to dark brown.
