Portanus phoenicius  sp. nov.

(Fig. 5 –8, 20– 26)

Type-locality. Parque Nacional de Sete Cidades, Piracuruca, Piauí State, Brazil.

Diagnosis. Pygofer lobe with posterior margin rounded ( Fig. 20View FIGURES 20 – 26), dorsocaudal margin with tooth turned inwardly ( Fig. 21View FIGURES 20 – 26); aedeagal apex with pair of elongate processes directed ventrally ( Fig. 25View FIGURES 20 – 26), each with one serrate margin ( Fig. 26View FIGURES 20 – 26), and lateral pair of rounded flanges directed ventrally ( Fig. 26View FIGURES 20 – 26).

Measurements (mm). Males: body length, 4.00; crown length, 0.30–0.38 (holotype); transocular width, 1.00; interocular width, 0.50; maximum pronotum width, 0.88 –1.00 (holotype = 0.94); forewing length, 3.00– 3.25 (holotype = 3.20). Females: 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.

Description. Head (Fig. 5–8), in dorsal view, with transocular width longer than crown median length; anterior margin angulate; frontogenal sutures reaching ocelli; texture shagreen except paired elliptical smooth areas at posterior half. Pronotum (Fig. 5, 8) as wide as transocular width; lateral margins angulate; dorsopleural carina inconspicuous; posterior margin straight; texture smooth with fine transverse striae. Mesonotum (Fig. 5, 8) with scutum smooth and scutellum shagreen. Forewings (Fig. 5–6) with inner anteapical cell open at base (m-cu 2 absent); median anteapical cell slightly longer than outer one.

Coloration. Head and thorax (Fig. 5) brown. Crown and mesonotum light-brown, pronotum brown, and venter brownish-yellow; some specimens with discolored areas at face. Pronotum (Fig. 5) with several ivory speckles. Mesonotum (Fig. 5) mostly ivory with paired large discolored lateral triangular areas at anterior half and paired small round discolored areas in between, appearing brown. Forewings (Fig. 5–6) 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 brown dorsally and brownish-yellow ventrally.

Male genitalia. Pygofer lobe ( Fig. 20–21View FIGURES 20 – 26), in lateral view, as long as high; posterior margin rounded; dorsocaudal margin with tooth turned inwardly; macrosetae distributed at dorsal half of lobe. Valve ( Fig. 22View FIGURES 20 – 26), in ventral view, subquadrate; as long as wide. Subgenital plates ( Fig. 22View FIGURES 20 – 26), in lateral view, extending posteriorly farther than pygofer apex; apical third abruptly upturned; basal third with transverse unpigmented line; ventral surface with few uniseriate robust macrosetae and several long and fine microsetae at apical half. Connective ( Fig. 23View FIGURES 20 – 26), in dorsal view, Y-shaped; basiventral process short. Styles ( Fig. 23–24View FIGURES 20 – 26), 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. 25–26View FIGURES 20 – 26), in lateral view, with shaft tubular and short, ventral margin expanded as lateral flange directed dorsally throughout most of its length, flange at apex folded and extended ventrally; dorsal apodemes absent; apex with pair of elongate processes directed ventrally, that may cross at median axis, each with posterior margin serrated at apical portion.

Female genitalia. Genitalia morphology indistinguishable from that of Portanus hastatus  sp. nov. ( Fig. 15–19View FIGURES 9 – 19).

Remarks. Portanus phoenicius  sp. nov. is indistinguishable from many other Portanus  species based on color pattern, being most similar to P. pictus Carvalho & Cavichioli, 2001  , P. uhleri Kramer, 1964  , and P. xavantes Carvalho & Cavichioli, 2001  because they share the broad aedeagal apex with a pair of elongate processes directed ventrally, which may cross in posterior view and have the apex acute. However, it can be distinguished from these and other Portanus  species by the characteristics given in the diagnosis, especially the well-developed lateral pair of apical rounded flanges on the aedeagus.

Etymology. The species epithet is in allusion to the phoenician civilization. The "seven cities" rocky formations, emblem of the Sete Cidades National Park, where the holotype was collected, are mythically thought to be evidence of phoenician settlements in Brazil ( Martin 2008).
