Stings of some species of <I>Lordomyrma</I> and <I>Mayriella</I> (Formicidae: Myrmicinae)

Abstract

The sting apparatus and pygidium are described for eight of 20 Lordomyrma species and one of five Mayriella species. The apparatus of L. epinotalis is distinctly different from that of other Lordomyrma species. Comparisons with other genera suggest affinities of species of Lordomyrma to species of Cyphoidris and Lachnomyrmex, while Mayriella abstinens Forel shares unusual features with those of Proatta butteli.
