Geitogonalia piei  sp. nov.

( Figs 15–21View FIGURES 15–21)

Diagnosis. Aedeagus ( Figs 20, 21View FIGURES 15–21) with preatrial process directed anteriorly; shaft very short, with pair of apical long and thick horn-shaped processes curved dorsally, longer than atrium and shaft together.

Measurement (in mm; 1 ♂). Length of body 7.5.

Male. Coloration. Anterior dorsum (crown, pronotum, and mesonotum) yellowish-green ( Figs 15, 16View FIGURES 15–21). Crown with narrow black stripe along posterior margin. Pronotum with orange transverse band posteriorly. Mesoscutellum yellow posteriorly. Forewing ( Figs 15, 16View FIGURES 15–21) yellowish on basal fifth; corium and clavus green; membrane dark brown; veins mostly yellow to greenish-yellow; apex and appendix dark brown. Face ( Fig. 17View FIGURES 15–21) pale yellow; apical segment of rostrum almost black. Thorax lateral and ventral portions pale yellowish-green. Legs pale yellow. Abdomen black.

Structure. Head ( Figs 15–17View FIGURES 15–21) moderately produced anteriorly, median length of crown approximately 1/2 of interocular width and 3/10 of transocular width; coronal suture distinct along its posterior half. Other features as in G. buccina  sp. nov.

Male genitalia. Pygofer ( Fig. 18View FIGURES 15–21), in lateral view, well produced posteriorly, posterior margin subquadrangular with lateral angles rounded; without processes; macrosetae distributed on posterior third and near dorsal margin; long and thin setae present ventrally and medially on anterior half. Valve ( Fig. 19View FIGURES 15–21), in ventral view, with lateral margins rounded, strongly constricted medially only on posterior margin. Subgenital plate ( Fig. 19View FIGURES 15–21), in ventral view, triangular, not fused to its counterpart basally, outer lateral margin basally almost parallel to inner lateral margin, then narrowing gradually towards apex, with uniseriate row of macrosetae intercalated with many and very long setae; in lateral view, not extending posteriorly as far as pygofer apex. Connective, style, and paraphyses resembling those of G. tetracorni  sp. nov. Aedeagus ( Figs 20, 21View FIGURES 15–21) symmetrical; preatrial process directed anteriorly; dorsal apodeme about 2/3 as long as rest of aedeagus, sinuous, base wide, narrowing apically, apex curved anteriorly; shaft very short, with pair of apical long and thick horn-shaped processes curved dorsally, longer than atrium and shaft together.

Female unknown.

Etymology. The new species is named in honor of Prof. Dr. Márcio Roberto Pie of the Departamento de Zoologia, Universidade Federal do Paraná, who collected the holotype.

Material examined. Holotype Ƌ:GoogleMaps  Southern   GoogleMaps Brazil, state of Paraná: “Brasil, Paraná / PE [Parque Estadual] do Marumbi / 48°55’W 25°26’S / III/2001 Pie M. leg.” (DZUP).

Remarks. The first author examined the connective, style, and paraphyses of the only known male of this new species, which are very similar to those of G. tetracorni  sp. nov. ( Figs 27, 28View FIGURES 22–30) and G. buccina  sp. nov. ( Figs 6, 7View FIGURES 1–9). However, due to an accident, they were lost after the initial examination and, unfortunately, could not be illustrated. This species is similar in color to the other two new species, but is easily distinguished from them by the short aedeagus ( Figs 20, 21View FIGURES 15–21) and the absence of the black stripe on the pronotum ( Fig. 15View FIGURES 15–21).
