Eryphus ; Napp & Martins, 2002: 84; Monné, 2005: 290 (cat.); 2012: 30 (cat.); Botero & Monné, 2018; Monné, 2022: 221 (cat.).

Etymology: Fusion of the names of two great deceased Brazilian researchers who dedicated their entire lives to the study of Cerambycidae :Dilma Solange Napp,and Ubirajara Ribeiro Martins de Souza (Bira). Masculine gender.

Type species: Eryphus bipunctatus Perty, 1832 , here designated.

Description: Frons transverse, flat. Genae shorter than lower eye lobe. Eyes finely faceted, emarginate;lower eye lobes large,occupy nearly entire lateral region of head.Last maxillary and labial palpomeres sub-cuneiform in both sexes (securiform in both sexes of E. laetus ). Mandibles triangular-shaped, non-angular on external lateral face, acute at apex. Antennae 11 antennomeres, filiform or nearly so, without sulci or carinae; in male, reaching or surpassing elytral apex; in female, not or reaching elytral apex (sometimes, weakly surpassing).Scape sub-cylindrical from basal quarter,from slightly shorter to slightly longer than antennomere III. Antennomere III shorter than V, longer or about as long as IV; antennomeres VIII-XI with similar length, filiform or somewhat serrate; antennomeres lacking apical spine, and dense and long setae ventrally. Prothorax rounded laterally, lacking lateral tubercle, not longitudinally carinate. Pronotum lacking tubercles. Procoxal cavities slightly open laterally,open behind. Prosternal process narrow centrally, expanded posteriorly (almost not expanded in E. flavicollis ). Mesoventral process as wide as or slightly narrower than mesocoxa, parallel-sided, without articular projections, notched at apex. Mesocoxal cavities closed laterally. Pro- and mesocoxae not distinctly elevated. Elytra parallel-sided, wider than posterior area of prothorax,flattened or slightly convex dorsally; apex variable. Femora pedunculate-clavate (femoral club not abrupt and not strongly widened); apex of metafemora reaching or not elytral apex, not reaching in female. Tibiae not carinate. Metatarsomere I as long or slightly longer than II-III together.

Remarks: Solangebira gen. nov. differs from Allodemus Zajciw, 1962 and Erythrochiton Zajciw, 1957 by the antennomere III shorter than V (longer in Allodemus and Erythrochiton). It differs from Eriphosoma Melzer, 1922 by the antennomere III longer than V (longer or subequal in Eriphosoma), and femora pedunculate-clavate (cylindrical or nearly so in Eriphosoma). Solangebira can be separated from Homogenes Thomson, 1862, by the prothorax lacking lateral tubercles(present in Homogenes). It can be separated from Callideriphus Blanchard, 1851 by the pronotum not longitudinally striate (striate in Callideriphus).

According to Napp & Martins, 2002 on their new genus Tacyba (translated):" Eryphus [= Solangebira, here named as Eryphus sensu Napp & Martins (2002)] differs from Tacyba gen. nov.: antennomeres VIII-XI long in both sexes, not tumid in females; prothorax wider than long, with sides uniformly rounded; elytra flattened dorsally, parallel-sid- ed and slightly convex close to apex; legs proportionally short; metafemoral club cylindrical; metatibiae cylindrical and just shorter than metafemora. In Tacyba: antennomeres VIII-XI shortened in both sexes, tumid in females; prothorax as long as wide, sub-hexagonal; elytra convex dorsally, narrowed about middle and convex at apex; legs proportionally long and stout; metafemora fusiform; metatibiae flattened and slightly longer than metafemora.″ However,the antennomeres VIII-XI in females of Tacyba is not different from that in males, which means they are not tumid, but they are somewhat wider than the previous segments, which does not occur in Solangebira except, apparently, in S.carinatus (Zajciw, 1970); the prothorax in S. carinatus is very similar to that in Tacyba, and is slightly longer than wide; the elytra is distinctly not flattened in S. tacuarembo (Napp & Martins, 2002) ( Fig. 2G), and S. bivittatus (Melzer, 1934) ( Fig. 2F), they are convex dorsally, and very weakly flattened in S. laetus (Blanchard, 1851); the elytral side is variable in Solangebira and can be identical or nearly so to that in Tacyba (for example, in S. carioca (Napp & Martins, 2002) ( Fig. 2D)); the length of the legs in Solangebira is variable,as well as the shape,and may be identical or nearly so as in Tacyba; the metafemora in Tacyba cannot be defined as fusiform, and is very similar to that in S. transversalis (Fairmaire & Germain, 1864), gradually widened from base to near apex; and the metatibia is somewhat variable in some specimens of Tacyba tenuis (Blanchard, 1851), and may be identical or nearly so as in Solangebira, especially regarding the flattening. Accordingly, the only reliable difference between Solangebira and Tacyba is the length of the antennomeres VIII-XI, which have similar length in the former and X-XI distinctly shorter than VIII-IX in the later. Apparently, S.carinatus ( Fig. 2E) and S.transversalis ( Fig. 2 H) do not belong to this genus. However, we could not examine specimens of S.carinatus and females of S.transversalis. Thus, we prefer to keep them provisionally in Solangebira.
