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
.
