| Abstract: | Abstract. The ventromental plates of larvae of twenty-six cytologi-cally identified species of Chironomus Meigen from Europe are described. Variation in plate features, including size, striae, inner and outer hook series, and ventral surface ornamentation, is reported. A principal components analysis based on plate characters is undertaken, and the taxonomic composition of the resulting groupings is discussed. |
