Within the Hydroporini, the Deronectes-group of genera are characterised by having the mesosternal fork and metasternal keel separated (or secondarily fused), the ventral elytral ridge posteriorly elevated but without ligula, and the male protarsus ventrally without adhesive discs. The genera of the group, viz. Deronectes Sharp, 1882, Stictotarsus Zimmermann, 1919, Scarodytes Gozis, 1914, and Nebrioporus Regimbart, 1906, are reclassified and a hypothesis of their phylogenetic relationships is presented. Karyotypes of 14 European species of Hydroporinae are discussed. Nebrioporus is extended to include most species with parameres with apex hook-like and sclerotised, with Potamonectes Zimmermann, 1921, as a junior synonym, syn. n. Nebrioporus s. str. and Zimmermannius Guignot, 1941 are recognized as subgenera of Nebrioporus. Scarodytes is kept as a separate genus because of its characteristic ventral sculpture and seemingly higher number of autosomes than in Nebrioporus. The species with simple parameres previously placed in Potamonectes are transferred to Stictotarsus together with S. bertrandi (Legros, 1956), previously in Deronectes. Consequently, Trichonectes Guignot, 1941, is a junior subjective synonym of Stictotarsus, syn.n. In an appendix, a check-list is provided for the species of the Deronectes-group. The subgenus Nebrioporus s. str. is divided into three species-groups: the kilimandjarensis-, the abyssinicus-, and the depressus-groups.
