Diagnosis. Pygofer lobe with poster margin straight ( Fig. 14 ), ventrocaudal margin with inner craw-like process extending dorsocaudally ( Fig. 15 ); aedeagus elongate, with apical half curved dorsally with mouth-shaped opening in posterior margin, apex truncated ( Fig. 19 ).

Measurements (mm). Male: total length 5.00. Female unknown.

Coloration. Head and thorax light brown; venter brownish-yellow. Crown light brown ( Fig. 13 ), with median line, apical triangular outline and two apical small spots, ivory. Pronotum light brown ( Fig. 13 ) with several ivory speckles. Scutellum ( Fig. 13 ) mostly ivory with paired, large dark lateral triangular areas at anterior half. Forewings translucent brown; veins marked with dark brown with small white spots; white regions on costal margin at apical half and apex of claval veins; apex completely dark brown with translucent areas on apical cells.

Description. Crown ( Fig. 13 ), in dorsal view, produced anteriorly with transocular width longer than crown median length; anterior margin lightly angulate; frontogenal sutures not reaching ocelli. Pronotum as wide as transocular width; lateral margins angulate; dorsopleural carina inconspicuous; posterior margin straight; texture smooth with transverse striae. Scutellum smooth. Forewings with three closed anteapical cells, median anteapical cell slightly longer than adjacent ones; third apical cell with apex broad, fourth apical cell subtriangular. Appendix absent.

Male genitalia. Pygofer lobe ( Fig. 14 ), in lateral view, longer than high; posterior margin straight; ventroapical margin with inner craw-like process, extending dorsocaudally ( Fig. 15 ); macrosetae on dorsal half of lobe. Subgenital plates, in lateral view, extending posteriorly farther than pygofer apex; 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 ( FIg. 16 ). ConnectIVe ( Fig. 17 ), in dorsal view, Y-shaped; basiventral process short. Styles ( Fig. 18 ), in dorsal view, with apical fourth wide and forked, with internal branch elongate and acute. Aedeagus ( Fig. 19 ), in lateral view, elongate; apical half curved dorsally with mouth-shaped opening in posterior margin; apex truncated; apodemes absent. Gonopore apical.

Type-material. Holotype: male, “Prov.[ince] Del Sara / Bol.[ivia] Steinbech / C. M. Acc 5064 // Feb.[ruary] / 1913 // Paratypus // Scaphoideus / punctulatus / n. sp. Osb.[orn] // Paratype / S. Punctulatus / Osb.[orn] / Carn.[egie] Mus. [eum] Ent.[omology]” ( CMNH).

Etymology. The species epithet is a noun in apposition taken from the type locality.

Remarks. Portanus delsara sp. nov. is very similar to P. sagittatus Carvalho & Cavichioli, 2004 , both species sharing: (1) similar shape of ivory maculae on crown apex; and (2) ventroapical margins of male pygofer with inner craw-like process, extending dorsocaudally. However, the new species can be distinguished from the latter and other Portanus species by its aedeagus elongate, with apical half curved dorsally with mouth-shaped opening in posterior margin, and apex truncated.
