Iragua ferruginea Cavichioli 1991
No full textIragua ferruginea Cavichioli, 1991 (Figures 8–22) Female. Total length 10.9–11.4 mm (n = 2). External morphology and color pattern (Fig. 8) as in the specific description of Cavichioli (1991: 81). Terminalia with abdominal sternite VII (Figs. 9–10), in lateral view, strongly produced ventrally, keeled medially; in ventral view, lateral margins convergent posteriorly, posterior margin with small but distinct median emargination. “Internal” sternite VIII (Fig. 11), in dorsal view, with two large, central sclerotized semicircular areas, one located above the other. Pygofer (Fig. 12), in lateral view, well produced posteriorly, subtriangular, apex subacute; with large macrosetae distributed mostly on posterior two-thirds of disk. Valvifer I (Fig. 12), in lateral view, lozenge-shaped. Valvulae I (Fig. 13), in ventral view, distinctly expanded basally; blade, in lateral view, approximately rectilinear beyond basal curvature but with apical portion slightly curved ventrally; apex acute; dorsal sculptured area extending from basal portion to apex, formed by scale-like processes arranged in oblique lines (Fig. 15), except basally with more linear processes (Fig. 14); ventral sculptured area restricted to apical portion, formed by aligned or nearly aligned scale-like processes; ventral interlocking device located on basiventral half of blade. Valvulae II (Fig. 16), in lateral view, moderately expanded beyond basal curvature; dorsal margin convex; apex (Fig. 20) broadly rounded; ventral preapical prominence (Fig. 21) distinct; dorsal margin with about 35 subtriangular teeth (Figs. 18–19), usually clearly separated from each other; teeth at basal ascending portion (Fig. 17) more rounded and of irregular form; irregular denticles (serration) distributed on teeth; dorsal apical portion of blade without denticles, much shorter than ventral apical portion, the latter with irregular denticles. Gonoplacs (Fig. 22) of the usual form in sharpshooters (in lateral view, with distal half expanded and with obtuse apex). Material examined. Three females: Brazil, state of Rondônia, Ouro Preto do Oeste, 8/X/1986, J. Becker col. (MNRJ). Taxonomic notes. Our female specimens are from the type-locality of I. ferruginea in the Amazonian state of Rondônia (northern Brazil) and their external form and color pattern (Fig. 8) are as in the original specific description of Cavichioli (1991). We found in the female terminalia of I. ferruginea a conspicuous and peculiar “internal” sternite VIII, which is formed by two large, central sclerotized semicircular areas, one located above the other (Fig. 11). In his detailed description of the genus, Young (1977) did not mention this structure (sclerites of the genital chamber in his terminology). In the valvulae II of the ovipositor, we call attention to the dorsal apical portion (i.e., the distal area between the last tooth and the blade apex), which has no denticles and is much shorter than the ventral dentate apical portion; the apex of the blade is broadly rounded (Figs. 16, 20–21). These features of the valvulae II occur also in Ladoffa, a genus considered closely related to Iragua (see Young 1977: 357, fig. 286m of L. sannionis Young, 1977).Published as part of Cavichioli, Rodney R. & Mejdalani, Gabriel, 2017, The sharpshooter genus Iragua Melichar: a new Colombian species, the female of I. ferruginea Cavichioli, and a key to males of the genus (Insecta: Hemiptera: Cicadellidae: Cicadellini), pp. 120-126 in Zootaxa 4281 (1) on pages 122-125, DOI: 10.11646/zootaxa.4281.1.12, http://zenodo.org/record/81598
Costanana nupera Domahovski & Cavichioli 2023, comb. nov.
No full textCostanana nupera (Van Duzee, 1907) comb. nov. Fig. 19 Gypona nupera Van Duzee, 1907: 61. Material examined Holotype JAMAICA • ♀; “ Mandev’le \ Ja. Apr. 06 ”, “ Van Duzee \ Collector”, “California Academy \ of Sciences \ Type Nº. 2327”; CAS 2327. Remarks This species is known based on a single female specimen from Jamaica (Fig. 19A–D) and was one of the 16 species not studied in the revision of the genus Gypona (DeLong & Freytag 1964). The external morphology and general coloration of Gypona nupera is very similar to that of Costanana cifi sp. nov. (Fig. 11E–F) – see remarks on this species – and because of that we decided to transfer this species to Costanana.Published as part of Domahovski, Alexandre C. & Cavichioli, Rodney R., 2023, Eight new species of Costanana DeLong & Freytag (Hemiptera: Cicadellidae: Gyponini): taxonomic changes, key to males, and description of Metacostana gen. nov., pp. 1-53 in European Journal of Taxonomy 889 (1) on page 36, DOI: 10.5852/ejt.2023.889.2245, http://zenodo.org/record/826945

Balacha rubripennis Cavichioli & Sakakibara 1988
No full textBalacha rubripennis Cavichioli & Sakakibara, 1988 (Fig. 19) Notes. We have studied Argentinian specimens that have a color pattern similar to B. lepida, but their male terminalia indicate that they belong in B. rubripennis. These specimens have the ground color of the anterior dorsum (head and pronotum) orange to red with dark brown to black markings as follows: anterior margin of crown with two large spots; posterior margin of crown with pair of maculae extending to ocelli; broad macula over coronal suture; anterior margin of pronotum with two large spots, posterior margin with broad transverse macula connected to median stripe, the latter linked laterally to anterior pair of spots; pronotum with smaller macula behind each compound eye and extending to posterior margin. Mesonotum almost entirely dark brown to black, delimiting pair of oblique orange to red areas. Forewing mostly dark orange to red, without spots. Material examined.
