Hypononera ergatandria (Forel, 1893) – a cosmopolitan tramp species different from H. punctatissima (Roger, 1859) (Hymenoptera: Formicidae) by Bernhard Seifert

“… Strong evidence is presented that the ponerine tramp ants frequently found in hothouses around the globe and named for many decades Hypoponera punctatissima consist of two clearly separable species: Hypoponera punctatissima (Roger, 1859) and H. ergatandria (Forel, 1893). …”

The Ant Genus <i>Cardiocondyla</i> (Hymenoptera: Formicidae): The Species Groups with Oriental and Australasian Origin by Bernhard Seifert

“…Exploratory and hypothesis-driven data analyses of phenotypic characters support the separation of the cryptic species <i>Cardiocondyla minutior</i> Forel, 1899, <i>C. goa</i> Seifert, 2003 and <i>C. tjibodana</i> Karavajev, 1935, two of which have dispersed as tramp species to the New World. Missing development of postzygotic isolation due to very strong prezygotic barriers is indicated in the closely related species <i>Cardiocondyla latifrons</i> n.sp. and <i>C. micropila</i> n.sp. which produce fertile hybrids in laboratory rearings but apparently do not hybridize in a natural context even if nesting in close neighborhood. …”
