Lasioglossum (Dialictus) gaudiale ( Sandhouse, 1924)

[ Holotype: USNM; ♂ La Jolla, California, USA; August]

Lasioglossum gaudiale is found in the xeric regions of southwestern USA, and northwestern Mexico. According to Gardner & Gibbs (2023), it has been collected in the Lower Colorado Desert, the Gulf Coast, and the Sarcocaulescent Shrubland. Here, we include the records of L. tegulariforme from Sandhouse & Cockerell (1924), since we consider they were records of L. gaudiale . At the time of Sandhouse & Cockerell’s work, L. gaudiale was only known from the male, and the females were likely misidentified as L. tegulariforme , which would later contribute to L. gaudiale and L. tegulariforme being incorrectly synonymized. It is possible that some old L. gaudiale records also refer to L. angelicum , L. magnitegula , or L. stictaspis , but specimens that have been examined so far have been L. gaudiale . Additionally, we reviewed three specimens collected in the Gulf Coast in September 2016 (1 ♂), and the Sarcocaulescent Shrubland in October 2018 (2 ♀; EMEC). See fig. 175.
