The ant genus Stenamma Westwood (Hymenoptera: Formicidae) redefined, with a description of a new genus Propodilobus.

This dataset contains the digitized treatments in Plazi based on the original journal article Branstetter, M. G. (2009): The ant genus Stenamma Westwood (Hymenoptera: Formicidae) redefined, with a description of a new genus Propodilobus. Zootaxa 2221: 41-57, URL: http://hol.osu.edu/reference-full.html?id=22826AbstractThe myrmicine ant genus Stenamma Westwood is redefined and a new diagnosis of the worker caste is presented. Justified by both morphology and molecular data, two species are removed from Stenamma and transferred to the genus Lordomyrma Emery: L. bhutanensis (Baroni Urbani) comb. n. and L. sinensis (Ma, Xu, Makio & DuBois) comb. n. Based on compelling differences in morphology, a third species originally described in Stenamma is transferred to the genus Propodilobus gen. n.: P. pingorum (DuBois) comb. n. Molecular results also indicate that Stenamma, as newly defined here, is a monophyletic genus that forms a clade with Aphaenogaster Mayr and Messor Forel. Additional notes on the diversity and distributions of Stenamma, Lordomyrma, and Propodilobus are provided.Key words: ant taxonomy, molecular phylogenetics, Myrmicinae, Stenamma, Lordomyrma, Propodilobus
