“…However, Young (1967, 83) seemed to make it clear at that time that he could not “…decide… whether Brinkius [sic] of Guignot should be accorded recognition.” Even so, he soon (Young 1969) did synonymize Brinckius with Hydrodessus and provided a list of the included species. He then (Young 1970) added two more and provided a key to all the species. The next contribution was by Spangler (1985), who added five new species from Guyana and also provided a key to the species.…”

“…2B,C), and the description of the species is extensive, though it excludes a number of important diagnostic features. The description presented here is based on Spangler’s (1966) description and his figures and later keys (Spangler 1985; Young 1970). The extremely curved lateral margins of the pronotum, the distinctive color pattern on the elytron, and the shapes of the male genitalia are distinctive (Figs 2B, C), but Hydrodessus amazonensis does not appear to correspond to any specimens examined during this study.…”

“…New species have been described regularly over several years (Balfour-Browne 1953; Guignot 1957; Spangler 1966; 1985; Young 1970; Makahn 1994). Fortunately, these descriptions have largely been in the context of the group as a whole with keys and comparative diagnoses such that new species have largely been confidently identified as such.…”

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: Hydrodessus bimaculatus sp. n. (Venezuela), Hydrodessus brevis sp. n. (Venezuela), Hydrodessus concolorans sp. n. (Venezuela), Hydrodessus continuus sp. n. (Venezuela), Hydrodessus disjunctus sp. n. (Suriname), Hydrodessus fasciatus sp. n. (Brazil), Hydrodessus imparilis sp. n. (Ecuador), Hydrodessus keithi sp. n. (Brazil, Colombia, Ecuador), Hydrodessus kurti sp. n. (Suriname), Hydrodessus kylei sp. n. (Suriname, Venezuela), Hydrodessus laetus sp. n. (Venezuela), Hydrodessus latotibialis sp. n. (Peru), Hydrodessus maculatus sp. n. (Guyana, Venezuela), Hydrodessus morsus sp. n. (Venezuela), Hydrodessus palus sp. n. (Venezuela), and Hydrodessus tenuatus sp. n. (Suriname). The following new synonyms are established: Hydrodessus fragrans Spangler, 1985 = Hydrodessus biguttatus (Guignot, 1957) syn. n. and Hydrodessus robinae Spangler, 1985 = Hydrodessus octospilus (Guignot, 1957), syn. n. One species is transferred from Hydrodessus to Amarodytes Régimbart, Amarodytes 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.

Description of the second instar of Matus leechi Young (Coleoptera: Adephaga: Dytiscidae) is presented including a chaetotaxic and porotaxic analysis of the cephalic capsule, head appendages, legs, last abdominal segment and urogomphi. Larvae of M. leechi are distinguished from those of other species of the genus Matus Aubé by (1) the non-pseudochelate pro-and mesothoracic tibiae, (2) the presence of spatulate lamellae clypeales, (3) the absence of secondary setae on the cephalic appendages, and (4) the very elongated urogomphi. It is postulated that the pseudochelate legs found in other species of Matus evolved within the genus Matus.
