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.
