4D9A9C4969FA5713B896731C80906A69.taxon	diagnosis	Diagnosis. The species can be distinguished from all other species of Acanthoventris gen. nov. by the following combination of features: anterior margin of head slightly convex; timbal cover long, apex acute, almost reaching the lateral metascutellar plate; operculum long, covering the timbal cavity and the apex reaching the auditory capsule; basal lobe long, almost reaching the apex of ventral apophyses; lateral margin of uncus straight becoming convex in the ventral apophyses; ventral apophyses grooved, internal margin forming a sub-rectangular distally directed and posterior margin forming an acute angle posteriorly directed. This species has a similar morphology to A. faustopsaltrius sp. nov. and A. rubemi sp. nov. due the body color and bands, but A. charrua sp. nov. can be distinguished by the longer timbal cover, the operculum slightly longer, covering the auditory capsule, the gutter at apex of the operculum slender, and the basal lobe of pygofer shorter.	en	Ruschel, Tatiana Petersen, Bianchi, Filipe Michels, Campos, Luiz Alexandre, Carvalho, Gervasio Silva (2023): Total evidence analysis elucidates the tangled systematic scenario within Fidicinini (Hemiptera: Auchenorrhyncha, Cicadidae).

F7E2172E007E5537AD8C980EE6D71AE0.taxon	diagnosis	Diagnosis. The species can be distinguished from all other species of Acanthoventris gen. nov. by the following combination of features: anterior margin of head slightly convex; lateral and sub-lateral lobes of pronotum with wrinkles and black setae; posterior margin of basisternum 3 tightly acute; apex of operculum reaching the auditory capsule but not covering the timbal cavity; gutter of operculum broad present in all margins; apical cell 2 half of length of apical cell 1; timbal cover short, the apex acute not reaching the lateral metascutellar plate; sternite VII sub-triangular. This species has a similar morphology to A. charrua sp. nov. due the body color and bands. A. rubemi sp. nov. can be distinguished by the timbal cover shorter, the operculum slightly shorter, not covering the auditory capsule, the gutter at apex of the operculum broad, and the basal lobe of pygofer longer.	en	Ruschel, Tatiana Petersen, Bianchi, Filipe Michels, Campos, Luiz Alexandre, Carvalho, Gervasio Silva (2023): Total evidence analysis elucidates the tangled systematic scenario within Fidicinini (Hemiptera: Auchenorrhyncha, Cicadidae).

Uncus (Fig. 22 H, I): lateral margin slightly straight becoming tightly convex in the ventral apophyses; lateral branches of uncus undeveloped, convex bud-like, away from the midline; the internal margin slightly convex; ventral apophyses grooved with the apices strongly sclerotized; internal margin forming a sub-rectangular distally directed and with the posterior apex salient; posterior margin inclined and with an acute angled lateral and posteriorly developed. Pygofer (Fig. 22 J) sub-cylindrical; the basal lobe reaching the apex of ventral apophyses. Theca (Fig. 22 K-M) dorsally developed with the ventral thecal process with two sclerotized projections toward the anterior margin; vesica tightly extruded and adorned with cornuti in the inner and outer surfaces. - Female: Unknown.	en	Ruschel, Tatiana Petersen, Bianchi, Filipe Michels, Campos, Luiz Alexandre, Carvalho, Gervasio Silva (2023): Total evidence analysis elucidates the tangled systematic scenario within Fidicinini (Hemiptera: Auchenorrhyncha, Cicadidae).
