Domahovski, Alexandre Cruz & Cavichioli, Rodney Ramiro, 2022, Five new Brazilian species of Fuminana Freytag (Hemiptera: Cicadellidae: Gyponini) with new records and key to males, Zootaxa 5219 (5), pp. 467-485 : 475

Fuminana incurvata sp. nov.

( Figs 35 –47, 78, 79, 84)

Diagnosis. Pygofer (Fig. 41) apex strongly tapered, almost digitiform and acute. Style (Fig. 45) apex with subapical constriction, bent dorsally and acute apically, with a minute subapical process on dorsal margin and a long subapical process on ventral margin. Aedeagus (Figs 46, 47) strongly curved ventrally; apex with pair of long processes directed ventrally.

Measurements. Total length: Holotype male: 13.7 mm.

Coloration. Frons (Fig. 36) with black punctures only near crown-face transition. Other characteristics as in generic description.

Description. Prothoracic leg ( Fig. 84 ) with filiform setae on ventral surface of femur and tibia. Other characteristics as in generic description.

Male terminalia. Sternite VIII (Fig. 39) 1.6x wider than long; posterior margin slightly sinuate. Valve (Fig. 40) 1.8x wider than long. Pygofer (Fig. 41) 2.5x longer than maximum height; ventral margin rounded; dorsal margin strongly excavated and deeply concave in dorsal view; apex strongly tapered, almost digitiform and acute. Subgenital plate (Fig. 42), in ventral view, 3.9x longer than wide; inner margin straight; outer margin weakly rounded; apex narrowed and rounded. Connective (Fig. 43) longer than wide; stem length longer than half basal width of connective. Style (Fig. 44), in dorsal view, outer lobe poor developed; in lateral view (Fig. 45), blade narrow, slightly broadened subapically, curved near base and straight posterad; apex with subapical constriction, bent dorsally and acute apically, with a minute subapical process on dorsal margin and a long subapical process on ventral margin, bearing minute denticles. Aedeagus (Figs 46, 47) dorsal apodeme with laterodorsal angles strongly elongated and divergent; shaft arched, long and thin, strongly curved ventrally; apex weakly sclerotized on ventral margin, forming pair of long processes directed ventrally.

Female. Unknown.

Etymology. The new species name comes from the Latin word ‘ incurvatus ’ and means arched. It refers to the strongly arched shaft of the aedeagus.

Material examined. Holotype male: “Vilhena, RO \ 20/XII/1984 \ C. Elias, leg. \ Polonoroeste” ( DZUP).

Remarks. Fuminana incurvata sp. nov. is easily recognized because it is the only species of the genus with the aedeagus curved ventrally (Fig. 46).
