Abstract

Portanus Ball, 1932 comprises 45 species that occur in Brazil, including Portanus felixi sp. nov. described and illustrated herein. The genus is close to Paraportanus Carvalho & Cavichioli, 2009 and can be distinguished from it by having a transversal groove on the basal third of the subgenital plates. The new species can be distinguished from the other species of the genus by the characters of male genitalia, especially by the pygofer with the apical process pointed, sclerotized and dorso-ventrally directed; and by the aedeagus with apodeme on the basal third.

Highlights

Portanus Ball, 1932 is characterized by the following character combination: crown produced; anterior margin ranging from rounded to subangulate in dorsal view, without carinae between the transition with the face; ocelli on anterior margin, equidistant from anterior angle of the eyes and from the coronal suture, this presents itself as long as half the length of the crown; antennae as long as the body; styles with apex broad and bifid
Body light brown with white spots sparsely distributed; crown and apex of forewing dark brown; pygofer produced posteriorly with a long spiniform process, acute and directed dorsoventrally; aedeagus with dorsal apodeme in basal third; shaft of aedeagus with apex broad bearing a median tooth
Crown light brown with black anterior margin; anterior margin with a narrow yellow band involving the eyes, ending in a black spot at apex of the crown; disc of the crown with whitish band along the coronal suture and several unsightly yellow spots widely distributed
