Notes. Gusenleitner (2002) described the monotypic genus Interzumia View in CoL to accommodate the new species Interzumia rufonigra View in CoL . He compared Interzumia View in CoL with the American genus Montezumia de Saussure View in CoL , stating that the two genera are closely related and differentiated only by the absence of epicnemial carina in Interzumia View in CoL . The similarity to Montezumia View in CoL seems to be only superficial since most morphological characters differ among the two genera (e.g. morphology of propodeum). The holotype of Interzumia rufonigra View in CoL was not available for direct examination, but its description and the study of the holotypes of Pareumenes mediator Gusenleitner (a junior synonym of I. rufonigra View in CoL ) and of the related P. mirificus show that Interzumia View in CoL can be considered a junior synonym of Pareumenes (Brachyparmenes) . It is to be noted that Pareumenes rufoniger and P. mirificus differ from P. punctatissimus Giordani Soika View in CoL , the type species of Brachyparmenes , in the shape of T1: elongated and weakly convex in P. punctatissimus View in CoL , shorter and strongly convex in P. rufoniger and P. mirificus . These differences are here considered of specific value only and not indicative of different (sub)genera, but a complete phylogenetic analysis of Pareumenes View in CoL and related genera is needed to better understand the limits of this heterogeneous group.

The shiny apicolateral lamelliform appendices of T1, mentioned as distinctive of Interzumia both in the original description ( Gusenleitner 2002) and in the key to genera published by Carpenter et al. (2009), are just the reflection of the basalmost margin of T2, serving as articulation with T1 and observed in most Eumeninae with various degree of development.
