Abstract

The Neotropical diving beetle genus Hydrodessus J. Balfour-Browne, 1953 (Coleoptera: Dytiscidae: Hydroporinae: Bidessini) is revised. Thirty species are recognized. The following new species are described: H. bimaculatus sp. n. (Venezuela), H. brevis sp. n. (Venezuela), H. concolorans sp. n. (Venezuela), H. continuus sp. n. (Venezuela), H. disjunctus sp. n. (Suriname), H. fasciatus sp. n. (Brazil), H. imparilis sp. n. (Ecuador), H. keithi sp. n. (Brazil, Colombia, Ecuador), H. kurti sp. n. (Suriname), H. kylei sp. n. (Suriname, Venezuela), H. laetus sp. n. (Venezuela), H. latotibialis sp. n. (Peru), H. maculatus sp. n. (Guyana, Venezuela), H. morsus sp. n. (Venezuela), H. palus sp. n. (Venezuela), and H. tenuatus sp. n. (Suriname). The following new synonyms are established: H. fragrans Spangler, 1985 = H. biguttatus (Guignot, 1957) syn. n. and H. robinae Spangler, 1985 = H. octospilus (Guignot, 1957), syn. n. One species is transferred from Hydrodessus to Amarodytes Régimbart, A. soekhnandanae (Makhan, 1994), comb. n. Habitus photographs (dorsal and lateral) and photos of the ventral surfaces are provided for most species. Line drawings of male and female genitalia and other diagnostic features are also provided along with distribution maps.
