Biology

Lasioglossum mestrei has been recorded from flowers of Bidens pilosa L. ( Asteraceae ).

Remarks

There has been some recent and past confusion regarding this species, such that some individuals recently reported to be L. mestrei are misidentified specimens of L. gundlachii . Historical records may be due to confusion over the secondary homonymy of the two Cresson (1865) names Augochlora parva and Panurgus parvus . It was first recorded from Puerto Rico as Augochlora parva by Dewitz (1881). Baker (1906) treated A. parva and P. parvus as if they belonged to the same species, which was accepted by later authors ( Cockerell 1910; Alayo 1973, 1976). The lectotype designations for these two names by Cresson (1916) invalidates this interpretation. Some records of L. mestrei from Puerto Rico may be derived from specimens of L. enatum sp. nov. due to the earlier use of the Cresson names.
