title: Morphometric analysis and taxonomic revision ofAnisopteromalusRuschka (Hymenoptera: Chalcidoidea: Pteromalidae) - an integrative approach.
abstract: We use an integrative taxonomic approach to revise the genusAnisopteromalus. In particular, we apply multivariate ratio analysis (MRA), a rather new statistical method based on principal component analysis (PCA) and linear discriminant analysis (LDA), to numerous body measurements and combine the data with those from our molecular analysis ofCytbandITS2genetic markers (on a subset of species) and all available published data on morphology, karyology, behaviour, host associations and geographic distribution. We demonstrate that the analysis of quantitative characters using MRA plays a major role for the integration of name-bearing types and thus for the association of taxa with names. Six species are recognized, of which two are new:A. cornisBaursp.n.andA. quinariusGokhman & Baursp.n.ForAnisopteromalus calandrae(Howard), a well-known, cosmopolitan parasitoid of stored-product pests, we have selected a neotype to foster continuity and stability in the application of this important name. The species was sometimes confused with the relatedA. quinariussp.n., another cosmopolitan species that is frequently encountered in similar environments. We also show that several species originally described or later put underAnisopteromalusactually belong to different genera:Cyrtoptyx camerunus(Risbec)comb.n.;Meraporus glaber(Szelényi)comb.n.;Dinarmus schwenkei(Roomi, Khan & Khan)comb.n.Neocatolaccus indicusAyyar & Mani is confirmed as a junior synonym ofOxysychus sphenopterae(Ferrière)syn.n.andAnisopteromalus calandrae brasiliensis(Domenichini)stat.rev.must be considered as a valid but doubtful taxon.
