Portanus hastatus  sp. nov.

( Fig. 1 –4View FIGURES 1 – 4, 9– 19View FIGURES 9 – 19)

Type-locality. Parque Nacional de Ubajara, Ubajara, Ceará State, Brazil.

Diagnosis. Pygofer lobe apex acute spinelike ( Fig. 9View FIGURES 9 – 19); aedeagus with pair of elongate dorsoapical processes ( Fig. 13–14View FIGURES 9 – 19).

Measurements (mm). Male: body length, 4.50; crown length, 0.38; transocular width, 1.00; interocular width, 0.50; maximum pronotum width, 1.00; forewing length, 3.50. Females: body length, 4.50; crown length, 0.38–0.50; transocular width, 1.10; interocular width, 0.60; maximum pronotum width, 1.00– 1.10; forewing length, 3.50–3.75.

Description. Head ( Fig. 1–4View FIGURES 1 – 4), in dorsal view, with transocular width longer than crown median length; anterior margin angulate; frontogenal sutures reaching ocelli; texture shagreen. Pronotum as wide as transocular width; lateral margins angulate; dorsopleural carina inconspicuous; posterior margin straight; texture smooth with transverse striae. Mesonotum ( Fig. 1, 4View FIGURES 1 – 4) with scutum smooth and scutellum shagreen. Forewings ( Fig. 1–2View FIGURES 1 – 4) with three closed anteapical cells, median anteapical cell slightly longer than others.

Coloration. Head and thorax ( Fig. 1–3View FIGURES 1 – 4) brown; venter brownish-yellow; some specimens with discolored areas at face. Crown ( Fig. 1View FIGURES 1 – 4) with median line, apical triangular outline, lateral small spots, ivory. Pronotum ( Fig. 1View FIGURES 1 – 4) with several ivory speckles. Mesonotum ( Fig. 1View FIGURES 1 – 4) mostly ivory with paired large lateral round areas at anterior half and variable smaller maculae, discolored, appearing brown. Forewings ( Fig. 1–2View FIGURES 1 – 4) translucent brown; veins marked with dark brown with small white spots; four hyaline regions on costal margin at apical half; apex completely dark brown. Female abdomen dark brown dorsally and brownish-yellow ventrally.

Male genitalia. Pygofer lobe ( Fig. 9View FIGURES 9 – 19), in lateral view, longer than high; subtriangular; posterior margin acute; few macrosetae on apex. Valve ( Fig. 10View FIGURES 9 – 19), in ventral view, trapezoidal; longer than wide. Subgenital plates ( Fig. 9–10View FIGURES 9 – 19), in lateral view, extending posteriorly farther than pygofer apex; apical third slightly upturned; basal third with transverse unpigmented line; ventral surface with few uniseriate robust macrosetae and many long and fine microsetae at apical half. Connective ( Fig 11View FIGURES 9 – 19), in dorsal view, Y-shaped; basiventral process short. Styles ( Fig. 11–12View FIGURES 9 – 19), in dorsal view, with apical fourth wide and appearing bifid because of an elongate and robust preapical lobe; apex acute. Aedeagus ( Fig. 13–14View FIGURES 9 – 19), in lateral view, with short and tubular shaft; short dorsal apodemes; apex with pair of elongate straight processes directed dorsally and acute.

Female genitalia. Sternite VII ( Fig. 15View FIGURES 9 – 19) approximately rectangular; posterior margin slightly convex. Pygofer ( Fig. 16View FIGURES 9 – 19) lobe longer than high; dorsal margin with concavity at apical third; long macrosetae distributed along ventral margin, more concentrated at apical half; microsetae along dorso-apical margin; apex narrowly round.

Gonoplac ( Fig. 17View FIGURES 9 – 19) with basal half distinctly narrower than apical half; microsetae distributed near apex; apex acute. Valvulae I ( Fig. 18View FIGURES 9 – 19) with dorsal sculpturing strigate and ventral sculpturing maculose; apex acute. Valvulae II ( Fig. 19View FIGURES 9 – 19) with apical half expanded, narrowing to apex; dorsal surface with 25 continuous teeth, each subquadrate and without denticles; numerous anastomosed ducts extending to bases of teeth; apex without preapical ventral prominence or denticles.

Remarks. Portanus hastatus  sp. nov. is very similar to P. mariae Carvalho & Cavichioli, 2001  , both species sharing the: (1) shape of ivory maculae on crown apex; (2) ventroapical margins of male pygofer acute and ventrally projected; and (3) pair of elongate aedeagal apical process directed anterodorsally. However, the new species can be distinguished from the latter and other Portanus  species by its shorter aedeagal shaft and dorsal apodemes.

Etymology. The species epithet derives from the Latin word hasta, meaning spear, in allusion to its ivory marking of the crown.
