Leptogenys insularis

Holotype worker in. Labelled “52” upon the stage card, and “Oahu. 79/40.” Acc. Reg.: “1879 no. 40. 1 Leptogenys insularis Sm. Sandwich Is (Oahu). Presented by Rev. T. Blackburn, Honolulu.” A blue syntype label is on the specimen (as opposed to a red holotype label) as the type-series appeared originally to contain several workers. Smith says, “Not rare,......workers only taken.” On the other hand, the specimen may well be unique as the accessions register specifically states “1.”
