Description.

Length 5 mm from apex of head to apex of forewings at rest. Crown (Fig. 1) strongly produced anteriorly; anterior margin rounded in dorsal view; ocelli located on anterior margin, equidistant from the anterior angles of the eyes and coronal suture, the latter half length of crown.

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 ( Carvalho and Cavichioli 2009).

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.

Etymology.

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

Remarks.

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.
