Scaphoideus hasemani BAKER, 1923:532

Portanus spinosus DELONG, 1982:392 Syn. nov.

Diagnosis. Pygofer lobe with posterior margin rounded ( Fig. 2 ), dorsocaudal margin with tooth turned inwardly; aedeagus slender, curved and elongate with apex bearing three spiniform processes directed ventrally ( Figs 5, 6 ), median portion serrate just before slender, pointed, apical tip in apical view.

Measurements (mm). Male: body length, 4.50. Female: not examined.

Coloration. Head and thorax brown; crown and venter brownish-yellow. Pronotum ( Fig. 1 ) dark brown with several ivory speckles. Scutellum yellowish with basal angles brown ( Fig. 1 ). Forewings translucent brown; veins marked with dark brown with small white spots; two creamy white regions beside the costal cell; apex completely dark brown.

Redescription. Crown ( Fig. 1 ), in dorsal view, produced anteriorly and bluntly angled; with transocular width longer than crown median length; frontogenal sutures reaching ocelli. Pronotum as wide as transocular width; lateral margins angulate; dorsopleural carina inconspicuous; posterior margin straight; texture smooth with transverse striae. Scutellum ( Fig. 1 ) shagreen. Forewings with two closed anteapical cells, inner anteapical cell open; median cell slightly longer than adjacent ones; third apical cell with apex broad, fourth apical cell subtriangular.Appendix absent. Other characters as in generic description ( CARVALHO & CAVICHIOLI, 2003; DE SOUZA & TAKIYA, 2014).

Male genitalia. Pygofer lobe ( Fig. 2 ), in lateral view, as long as high; posterior margin rounded; dorsocaudal margin with tooth turned inwardly; macrosetae distributed at dorsal half of lobe. Subgenital plates, in lateral view, extending posteriorly farther than pygofer apex; in ventral view ( Fig. 3 ), with apical third slightly upturned; basal third with transverse unpigmented line; ventral surface of each subgenital plate with uniseriate robust macrosetae and many long and fine mIcrosetae at apIcal half. ConnectIVe ( FIg. 4 ), In dorsal view, Y-shaped; basiventral process short. Styles ( Fig. 4 ), In dorsal VIew, wIth apIcal fourth wIde and appearIng bIfid because of an elongate and robust preapical lobe; preapical region and apex of preapical lobe more sclerotized and sculptured; apex acute. Aedeagus ( Fig. 5 ), in lateral view, curved and elongate with apex bearing three spiniform processes directed ventrally ( Fig. 6 ); in apical view, median portion appearing serrate just before slender, pointed, apical tip. Gonopore apical.

Remarks. UHLER (1895) described Scaphoideus stigmosus from Santa Rosa del Sara, Bolivia (treated as a junior synonym of P. hasemani ), not far from the type locality of P. spinosus DeLong, 1982 , in Santa Cruz de la Sierra, Bolivia. We examined the specimens coupled with the descriptions and concluded that there are no characters which could delimit P. hasemani and P. spinosus . Moreover, the studied material does not exhibit any marked variation throughout the collection range, thereby enabling us to confidently treat P. spinosus as a junior synonym of P. hasemani .
