Veromessor lariversi

Smith, 1951

Ira La Rivers' Harvester Ant

Veromessor lariversi is a North American seed- first described by Smith in 1951. The species was historically associated with the Nevada Test Site region in Nevada. A 2021 taxonomic revision split V. lariversi into two species based on morphological and genetic differences, with the new species V. pseudolariversi described from material previously identified as V. lariversi. As a member of the Veromessor, it exhibits seed-harvesting and contributes to processes in arid environments.

Habitat

Desert environments; historically associated with the Nevada Test Site region.

Distribution

Nevada, specifically documented from the Nevada Test Site region. Distribution may require re-evaluation following the 2021 taxonomic split that described V. pseudolariversi.

Diet

Seed-harvesting (). Consumes plant seeds as primary food source.

Behavior

Seed-harvesting typical of the Veromessor. collect and store seeds in nest chambers.

Ecological Role

Functions as a seed-, contributing to seed and soil disturbance in desert . Nest construction creates cleared nest disks with enhanced vegetation growth along rims, potentially serving as refugia for plants during disturbances.

Taxonomic Revision

In 2021, a comprehensive taxonomic revision of the Veromessor split V. lariversi into two . The new species V. pseudolariversi was described based on morphological and genetic differences, with the and male of V. lariversi described by Cole (1955) serving as reference material. This split revealed cryptic diversity within what was previously considered a single species.
