Eucerotinae Viereck 1919

SubfamilyEucerotinae Viereck, 1919 Type genus. Euceros Gravenhorst, 1829. Diagnosis. Areolet open with no trace of wing vein 3 rs-m, spiracle of tergite 1 anterior to centre, anterior tergites wide. Female with antennae often centrally slightly flattened and widened, ovipositor tiny and weakly sclerotised (c. f. Fig. 1 C). Male with antennae centrally flattened and / or widened, often strikingly so. Remarks. In practice, the unusual ovipositor of the females and the antennae of the males, together with the distinctive robust habitus (especially the stout tergites), make Eucerotinae relatively easy to recognise. The female ovipositor is so vestigial, they may be mistaken for males at a quick glance. We have found the pectinate hind claws of Eucerotinae a useful additional character: some African male Acaenitinae, for example, can be surprisingly easy to confuse with female Eucerotinae but lack pectinate claws.
