Khalaim0Universidad Autónoma de Tamaulipas A new species, Stethantyx durrelli sp. n. from Brazil, is described and illustrated. The recently described genus Megalochus Khalaim & Broad is synonymized with Stethantyx. The new species is very similar to S. grandis (Khalaim & Broad), comb. n. but differs by the first metasomal segment being trapeziform in cross-section, the presence of a distinct glymma, and the metapleuron and dorsolateral area of the propodeum being densely punctate, without coarse irregular rugae. These two species are the largest and most conspicuous representatives of the subfamily Tersilochinae. A partial key to species of Stethantyx is provided. Taxonomy and generic limits of Stethantyx are discussed. http://jhr.pensoft.net/articles.php?id=5322
