Chinaia modesta Marques & Ale-Rocha, 2016, sp. nov.

Chinaia modesta sp. nov. Figs 22–30, 45 Diagnosis. Pygofer, in lateral view, wider basally, narrowing towards apex and without macrosetae or processes (Fig. 25); subgenital plates, in ventral view, with two macrosetae medially, close to inner margin (Fig. 26); aedeagus simple, without processes or lateral flaps, curved dorsally, “U” shaped; gonopore located in a “V” shaped apical opening (Figs 29–30). Measurements (mm). Male holotype: total length 5.87; crown median length 0.50; transocular width 1.45; interocular width 0.75; frons basal width 0.55; frons length 1.25; pronotum median length 0.65; width between humeri 1.65; mesonotum median length 0.60; mesonotum maximum width 1.0; forewing length 5.0; forewing maximum width 1.40. General color. Yellow with most of hind wing red (Fig. 45). Head, in frontal view, without distinct stains, except for upper two thirds of gena and maxillary plate, whitish, close to compound eye; maxilla with yellow lower third (Fig. 23); crown yellow, without stains (Fig. 22); pronotum with narrow orange stripe close to posterior margin and with lateral margins of the same color (Fig. 22). Proepisternum orange (Fig. 23); mesonotum with very narrow orange stripe on lateral margins (Fig. 22). Forewing (Fig. 24): clavus with yellow basal half; apex of clavus and entire middle third of wing red, apical third yellowish, being the only hyaline portion of the wing; with three slender brown stripes: one on middle area of clavus, and two on middle third, above claval suture, the most basal slightly longer than the one close to base of apical cells; three lilac stains also on middle third, two smaller close to longer brown stripe and one larger, close to the other brown stripe, above apex of clavus; a row of three brown small dots on apical third, between second and third apical cells; red venation. Brown hind wing with red venation. Yellow legs with setae of the same color. Description. Tentorial pits distinct and coronal suture indistinct; frons approximately two times its basal width; forewing about 3.5 times longer than its greatest width; anteapical cells slightly conspicuous apically. Male genitalia: in lateral view, pygofer wider basally, narrowing towards apex and without macrosetae or processes; posterior margin apparently truncated (it seems to be broken in the holotype) (Fig. 25). Subgenital plates fused only on basal third, approximately as long as pygofer, length about two times its basal width; in ventral view, with two macrosetae medially, close to inner margin (Fig. 26). Style moderately long and thickened, with apex hooklike, curved ventrally and sclerotized, and with large apical lobe, lateral to hook; two microsetae bellow hook (Figs 27– 28). Connective cruciform, approximately same length of style, articulate to aedeagus (Fig. 28). Aedeagus simple, without processes or lateral flaps, curved dorsally, “U” shaped; gonopore located in a “V” shaped apical opening (Figs 29–30). Anal tube simple, without processes. Female unknown. Geographical distribution. Brazil (Amazonas). Specimens examined. Male holotype (INPA), with following labels: “ BRASIL, Amazonas, Manaus, R.[eserva Florestal Adolpho] Ducke, 26 Km NE de Manaus, xi.1988, Arm.[adilha] Suspensa, 20m, J.A. Rafael leg. ”. Holotype condition. Glued direct to the entomological pin by the dorsal part of the pronotum, the pin is not well positioned on the right side of pronotum. Left antenna broken at base of flagellum. Left hind leg missing. Abdomen dissected. Etymology. From the Latin, modestus, moderate, gentle, unassuming, chaste. The species name is allusive to the male genitalia, especially to the pygofer and aedeagus, both of which are simpler than in other species of Chinaia, lacking any processes or flaps. Notes. Chinaia modesta sp. nov. is very similar to Chinaia bidentata Chiamolera & Cavichioli in the general coloration and male genitalia, although it differs from C. bidentata in by the morphology of the pygofer (Fig. 25) and aedeagus (Figs 29–30). The aedeagus of C. modesta does not have any processes, and in C. bidentata it has preapical and apical processes. Differences in the size of the forewing stripes and in the number of small dots present on apical third between the second and third apical cells of the forewing were also observed (Fig. 24).Published as part of Marques, Ana Paula Coelho & Ale-Rocha, Rosaly, 2016, Four new species of Chinaia Bruner & Metcalf (Hemiptera: Cicadellidae: Neocoelidiinae) from the Neotropical Region, pp. 145-155 in Zootaxa 4189 (1) on pages 150-151, DOI: 10.11646/zootaxa.4189.1.7, http://zenodo.org/record/16570
