Phylogenetic relationships of the tribe vatellini based on larval morphology, with description of derovatellus lentus (Coleoptera: Dytiscidae: Hydroporinae)

The phylogenetic relationships and putative monophyly of the diving-beetle tribe Vatellini are explored based on a cladistic analysis of 37 taxa and 122 chaetotaxic and morphological characters from larvae. For this purpose, larvae of the genus Derovatellus Sharp are described and illustrated in det...
