Tournier 1874: 103. Schilsky 1907: D. Sharp 1917a: 31. Solari 1930: 46. Hustache 1930: 236. Klima 1934: 127. Hoffmann 1954: 711, 713. Dieckmann 1983: 351, 373. Caldara &amp; O'Brien 1998: 137. Alonso-Zarazaga &amp; Lyal 1999: 88. Caldara 2013: 172.</p><p>Diagnosis. Scales subgranulate to granulate, moderately pitted except for ventrites 3–5 (char. 2.1). Rostrum with very few lateral and dorsal apical setae (char. 11.0). Scrobe not reaching eye (char. 17.1) and squamose (char. 14.1). Forehead between eyes not sulcate nor foveate (char. 24.0). Postocular lobe ventrally indistinct, not raised, not forming discontinuity with anterior prosternal margin (char. 30.0). Prosternal canal absent (char. 31.0). Elytra lacking declivital calli (char. 36.0). Tibiae arcuate at apical outer margin (char. 48.1); inner margin of tibiae lacking denticles. Penis with long apodemes (char. 110.0). Endophallus with basal sclerite complex formed by overlapped plates (char. 90.3).</p><p>Remarks. In the all-species analysis the genus is sister to all the other Bagoini with a strong support in BI (91% pp), and a lower support in ML and MP (respectively, 76% bs and 57% sr). In the type-species analysis the genus was not supported as sister to the remaining taxa of the tribe (BI: 50% pp, ML and MP lower than 50%). This incongruence was probably determined by the fact that Hydronomus is monotypic, whereas the other genera have a large number of species, sharing the character states differentiating them from Hydronomus . In the all-species analysis this resulted in a much stronger support for the clade encompassing the other genera of the tribe. Hydronomus shares with the other Bagoini several characters, such as the pitted scales, shape of the body, legs, and male and female genitalia. It differs from them by the absence of a prosternal canal and of pitted scales on some ventrites. Four unequivocal character states characterize Hydronomus (char. 11.0, 14.1, 17.1, 90.3) in respect to the other Bagoini: scrobe not reaching eyes and squamose (an apparently plesiomorphic state), rostrum with very few lateral and dorsal apical setae, endophallus with basal sclerite complex formed by overlapped plates.</p><p>This genus is presently composed only of the type species. However, we have an undescribed Chinese taxon belonging to this genus and differing from H. alismatis by the shape of the body of the penis and the basal sclerites.</p><p>Species included.

Tarsomere 3 cordate to linear; penis body ventrally membranous to fully sclerotized, usually with numerous basal or apical, more or less complex sclerites, with long to very short apodemes.</p><p>Remarks. In the all-species analysis the genus was almost maximally supported in BI (99% pp) but only weakly supported in ML (65% bs) and MP (63 % sr, Bremer support 1); in the type-species analysis its support in ML and MP was stronger (respectively, 78% bs and 72% sr, Bremer support 3).</p><p>Infrageneric classification of the genus Bagous is controversial. As already discussed, three large complexes of species are maximally, or nearly maximally supported: subgenera Parabagous, Hydronoplus and Hydrillaebagous new subgenus. The subgenus Macropelmus represents a further clade that includes a very large number of species sharing the shortening of the penis apodemes,. All other species, including B. binodulus, the type species of the genus, fall in a polytomy. The species available for the molecular analysis clustered in clades that match their placement in the topology of the BI reconstruction based on the morphological analysis. The type-species analysis produced the same pattern but with a further group (including Himaniphades and Abagous) that was not present in ML and had only low support. In accordance with the all-species analysis, we refer it to the subgenus Bagous as a species-group ( B. bipunctatus group).</p></div>	https://treatment.plazi.org/id/D17787854F5C1F280DD768311522FD5D	Public Domain	No known copyright restrictions apply.

The species presently included in this large widespread group are defined by one distinctive character of the endophallus, which consists of a pair of regions with distinctly concentrated and usually minute (rarely large) denticles toward the apex. Otherwise the group is heterogeneous in external structure such as tarsal shape and tibial curvature and dentition. Among the species of the complex, the females of B. bipunctatus and B. puncticollis possess a bursa with sclerites more or less bilobed and convex (as in unrelated species like those of the B. argillaceus group) (char. 116.2).

Vestiture of odd-numbered elytral intervals generally tesselate, with alternate rectangles of dark and pale scales; setae of odd-numbered elytral intervals surrounded usually by rosette of scales of same color. Elytra lacking declivital callosities (char. 36.0). Metasternum distinctly shorter than ventrite 1. Tibiae stout, with inner margin weakly bisinuate, lacking denticles and with several moderately short bristles; outer margin of tibiae, especially on hind tibiae, straight or nearly so toward apex (in lateral view) (char. 48.0).

Bagous tubulus group</p><p>Diagnosis. Body elongate-cylindrical. Pronotum 0.90x or more as long as broad (char. 26.1). Rostrum cylindrical, narrow, elongate (especially in female). Elytra nearly as wide as pronotum, without calli (char. 36.0). Sclerites complex within tube of penis body with a pair of submedian subapical sclerites posteriorly joined (char. 84.2), with chela-like basal portion. Median setal brush behind orifice situated at base of subapical sclerites (char. 93.1). Penis body elongate, with sinuate and subparallel sides. Tegmen lacking parameroid lobes (char. 111.2). Arms of spiculum ventrale longer than apodemes, with long apical setae (char. 113.1). Gonocoxites elongate.</p><p>Remarks. This group is characterized by the rostrum being cylindrical, narrow, and elongate (especially in the female), and a series of non-genital characters, e.g., the elongate body, and genital character states in part shared also by the species of the B. cylindricus group. Previously, B. elegans and B. majzlani (formerly Dicranthus) were separated in a distinct group by Caldara &amp; O’Brien (1998) due to their very distinctive habitus, including the pattern of the dorsal vestiture (char. 39.1 and 39.2), and the shape of the elytra in which the confluence of intervals 3 and 9 is markedly raised and forms a long posteriorly-projecting process (char. 38.1). In both all-species (Fig. 9) and type-species (Fig. 10) analyses this group was strongly supported; the complex comprising B. tubulus / B. friwaldszkyi was sister to the complex B. elegans / B. majzlani .

B. nodulosus group</p><p>Diagnosis. Penis body elongate with sides convergent from base to apex, with ventrobasal margin truncate; dorsal process very high and composed of a pair of very elongate sclerotized pieces, in dorsal view sinuate and joined at base with two small V-shaped vertical orificial sclerites (char. 83.1) and with membrane from dorsal process to proximal margin of orifice.</p><p>Remarks. This group is characterized by a very peculiar shape of the penis, especially due to the high dorsal process, and the sclerites. This group was also supported in the phylogenetic analysis (BI: 95% pp; ML: 75% bs; MP: 59% sr). Moreover, the two taxa included in this group, which are largely widespread in the western Palaearctic region, are apparently the only two species living on Butomus umbellatus L. ( Butomaceae). However, they differ from each other in several external characters. Apart from the general habitus which is distinctly thinner, B. nodulosus has a very well-developed declivital callus of interval 5, long and distinctly apically curved tibiae, with distinct denticles, elongate and linear tarsi. In contrast, B. validus has a rostrum with numerous scale-like setae along the ventro-lateral margins (char. 12.1) and penis body with sclerotized subtriangular plate behind the dorsal process, (char. 95.1). Due to these differences these species were placed in two separated monotypic groups by Caldara &amp; O’Brien (1998).</p><p>Species included.
