Felix, Márcio, Mejdalani, Gabriel, Domahovski, Alexandre C. & Cavichioli, Rodney R., 2022, Eight new Brazilian species of Fonsecaiulus (Hemiptera: Cicadellidae: Cicadellini) new records of species, and key to males of the genus, Zootaxa 5195 (2), pp. 101-124 : 107-108

Fonsecaiulus longiramus sp. nov.

( Figs 27–34 )

Etymology. The specific epithet, longiramus , refers to the very long paraphyses rami ( Fig. 33 ).

Total length (mm). Male holotype 5.44.

Color ( Figs 27–29 ). Dorsum brown with three longitudinal yellow stripes extending from anterior margin of crown to apex of clavus; median stripe narrowed posteriorly from median portion of pronotum, continuing as narrow line along commissural margins; lateral stripes strongly narrowed on median portion of clavus. Corium with irregular yellow stripe extending from anterior portion of brachial cell to inner anteapical cell, strongly narrowed along anterior third; very narrow yellow stripe extending longitudinally near costal margin, posteriorly connected to yellow macula on median and outer anteapical cells.

Male terminalia. Pygofer ( Fig. 30 ), in lateral view, strongly produced posteriorly; posterior margin subtriangular; without processes; sparse macrosetae of distinct sizes on posterior portion and extending anteriorly over ventral portion. Valve ( Fig. 31 ), in ventral view, short and broad, subrectangular; anterior margin slightly concave medially. Subgenital plate ( Figs 30, 31 ), in ventral view, subtriangular, broad at basal half and narrow at apical half, outer margin rounded at basal half; plate fused to its counterpart along basal third; without macrosetae; in dorsal view, with two tiny dentiform processes at apical portion of basal half, not located close to each other, anterior process associated with style apex; in lateral view, plate not extending as far posteriorly as pygofer apex. Connective ( Fig. 32 ), in dorsal view, without stalk, forming transverse bar, with median keel. Style ( Fig. 32 ), in dorsal view, elongate, extending much farther posteriorly than connective; apophysis with inconspicuous preapical lobe; portion behind lobe distinctly narrowed, bearing setae; apex truncate, foot-shaped. Aedeagus ( Figs 33, 34 ) symmetrical; shaft, in lateral view, elongate, subcylindrical, strongly curved dorsally, with acute apex; without processes; gonopore located ventrally at apical third. Paraphyses ( Figs 33, 34 ), in lateral view, with rami very elongate, extending almost as far posteriorly as pygofer apex, each one with apical portion curved ventrally and expanded, apex truncate and with pair of lateral small spines; in ventral view, basal half of each ramus with slender process directed medially.

Female unknown.

Type material. Holotype: male, “ BRASIL Maranhão, Mirador \ Parque Estadual Mirador \ Base de Geraldina \ 063726S–455209W \ 28–30.ix.2006, J.A. Rafael & \ F.L. Oliveira, Varredura” ( DZUP).

Remarks. In F. longiramus sp. nov., the paraphyses rami are extremely elongate with expanded apices ( Figs 33, 34 ), two conditions that will easily distinguish it from the remaining known species of the genus. The pygofer is also strongly produced, extending posteriorly much farther than the subgenital plates ( Fig. 30 ).
