description: Portanus hasemani (Baker, 1923)
(Figs 1-6)
Scaphoideus hasemani BAKER, 1923:532
Scaphoideus punctulatus OSBORN, 1923:37
Portanus hasemani OMAN, 1936:370
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.
