Strumigenys alberti Forel 1893

Distribution. Mexico to Brazil and most Caribbean islands; one USA record from Nevada.

Comments. This is a common species with a large range in the Neotropics. A single specimen is known from the USA, collected by Emma Mackay. This specimen was collected in a natural area, underneath a small rock in a dry and rocky juniper shrubland in Spring Valley State Park in Lincoln Co., Nevada. This new record is well north of the previous range limit of the species (38° N vs. 23° N; Guénard et al. 2017; Janicki et al. 2016). The occurrence may be an introduction or a rarely collected native with a much larger range than previously known. According to W. Mackay, he immediately recognized it as a Strumigenys sp. and knowing no other collections of Strumigenys in Nevada, he and Emma Mackay spent quite a bit of time searching for additional specimens without luck. Other ants W. Mackay collected as part of the same collecting event were Tapinoma sessile ( Say, 1836) , Formica moki Wheeler, 1906 , Camponotus sansabeanus ( Buckley, 1866) , Camponotus vicinus Mayr, 1870 , Dorymyrmex sp. , Temnothorax sp., Solenopsis sp. , and Forelius sp. (unpublished data).
