Description of a new Brazilian Paraportanus and key to the species of the genus (Insecta, Hemiptera, Cicadellidae, Portanini) by Adenomar Neves de Carvalho
ZooKeys, iss. , pp.19-24


AbstractParaportanus longispinus,, a new leafhopper species from Roraima and Amazonas States, North Brazil, is described and illustrated. The new species can be recognized by the male genital features, especially the distal third of ventral margin of the pygofer with a dentiform short process; plates distinctly longer than pygofer, extending posteriorly beyond pygofer by approximately 1/3 of their length and aedeagus with one pair of spiniform process long crossed and directed ventrally. A checklist and key to males of all known Paraportanus species is provided.


The South American genus Paraportanus Carvalho & Cavichioli, 2009 is known from ten species (see checklist) from Brazil (Acre, Amazonas, Minas Gerais, Mato Grosso, Maranhão, Pará, Rondônia and Roraima states) and Peru. Among the Portanini, Paraportanus species can be recognized by the usually strongly produced male pygofer carrying a pair of strongly pronounced spiniform processes on the posteroventral margin, subgenital plates triangular narrowing to apex and connective Y-shaped with very short stem.

In the present paper, a new Paraportanus species from Roraima and Amazonas States (North Brazil) is described and a checklist and key to all known species is provided.

Material and methodsEdit

Techniques for preparation of male genital structures follow [1]. The dissected genital parts are stored in microvials with glycerin and attached below the specimens, as suggested by [2]. The descriptive terminology adopted herein follows mainly [3], [4]), except for the facial areas of the head ([5]).

Label data are given inside quotation marks with a reversed virgule (\) separating lines on the labels and a semicolon separating labels of a specimen.

The specimens studied belong to the Coleção Entomológica Pe. J. S. Moure, Departamento de Zoologia, Universidade Federal do Paraná (DZUP; Curitiba) and Instituto Nacional de Pesquisa da Amazônia (INPA; Manaus).

Pronotum (Fig. 1) convex, wider than head; lateral margins subangulate in dorsal view; with dorsopelural carinae; posterior margin straight. Forewings with three closed anteapical cells; median cell as long as the external; third and fourth apical cell subretangular. Others characters as in description generic ([6]).

Color of body light yellow with opaque areas on crown and pronotum. Crown light brown with pair of large black maculae between ocelli (Fig. 1); face with vertical brown stripe on laterofrontal suture, broader adjacent antenna. Forewings light yellow semi-hyaline with white maculae at apex.

Male genitalia with pygofer (Fig. 2) in lateral view, strongly produced posteriorly; posterior margin broadly rounded; distal third of ventral margin with short dentiform process; macrosetae distributed mostly on proximal third of dorsal margin, some smaller setae on ventral margin to apex. Subgenital plates (Fig. 3), elongate, distinctly longer than pygofer, extending posteriorly approximately 1/3 their length, triangular with lateral margin sinuate; ventro laterally with diagonal row of macrosetae over distal two thirds and several long fine setae. Connective (Fig. 4) Y-shaped with arms broadly divergent; stem very short with strong median keel. Styles (Fig. 4) with apical apophysis strongly curved. Aedeagus (Fig. 5) in lateral view, narrow basally; shaft expanded distally, abruptly curved dorsally and laterally compressed; a pair of long spiniform processes subapically on ventral margin (Fig. 6) crossed and directed ventrally; gonopore apical.

Female genitalia. The abdominal VII sternite, in ventral view, with anterior margin straight; posterior margin weakly sinuate, with a small rounded tooth medially.

Paraportanus longispinus sp. n., male holotype in lateral view.

The specific name is named for the long pair of spiniform processes of the aedeagus.


Paraportanus longispinus can be distinguished from the other known species of the genus by the following combination of features: (1) crown with two maculae between ocelli (Fig. 1); (2) distal third of ventral margin of pygofer with short dentiform process (Fig. 2); (3) aedeagus with a pair of long spiniform process, crossed and directed ventrally (Figs 5, 6). The male genitalia of the new species are similar to those of Paraportanus facetus (Kramer) but differ from this species in having the processes of the aedeagus longer and crossed.
