Paraphysiana marquescostae spec. nov.

( Figs 1–12)

Type-locality: Petite Montagne Tortue, French Guiana.

Material examined: Male holotype: “ FRENCH GUIANA: Petite\ Montagne Tortue P11\ 04°19'14.1N- 052°14'27.5W \ 24.XI.2010 \ Lamarre G. Leg ” “White sand forest\ Vitre trap ( V12 )” ( DZRJ) .

Diagnosis: Forewings ( Fig. 4) with five dark brown maculae near inner margin; male pygofer ( Fig. 5) with inner dorsal processes in apical half and inner ventral processes, twisted at apex; subgenital plates ( Figs 6, 7) with dorsal apical tooth; connective ( Fig. 8) T-shaped; styles ( Figs 8, 9) with apex bifid, chela-shaped; aedeagus ( Fig. 10) tubular, without process.

Length: Male holotype: 5.9 mm.

General color: Body ( Figs 11, 12) with ground color pale yellow. Crown, face, pronotum and mesonotum ( Figs 1–3) unmarked. Forewings ( Fig. 4) yellow hyaline; orange band adjacent to inner margin, extending from basal angle to clavus apex; five dark brown maculae near inner margin, three on clavus and two on corium, on brachial cell and inner anteapical cell; apex fuscous. Legs ( Figs 11, 12) pale yellow.

External morphology: Crown ( Fig. 1) about as long as wide; flattened. Pronotum ( Figs 1, 3) about 2.7 times wider than long; posterior margin concave. Mesonotum ( Fig. 1) about as long as wide. Forewings ( Fig. 4) with venation indistinct except apically; with three anteapicall cells and four apical cells; appendix narrow, extending to first apical cell.

Male genitalia: Pygofer, in lateral view ( Fig. 5), approximately triangular, higher basally and slightly tapering towards apex; with two pairs of inner processes: one pair longer, slender and sclerotized, adjacent to ventral margin, extending from base to apex of pygofer, with apices twisted and acute, and one dorsal pair shorter, extending from base of anal tube to apex of pygofer, apices sclerotized and hook-shaped; few short setae distributed on apical third. Subgenital plates extending to apex of pygofer; fused meadlly to the valve; completely fused to each other; in ventral view ( Fig. 6), approximately triangular, enlarged at base and narrowing toward apex; dorsal surface with sclerotized longitudinal band in middle third, where the styles are attached; apex rounded, with several fine setae; in lateral view ( Fig. 7), with pre-apical dorsal tooth. Connective, in dorsal view ( Fig. 8), T-shaped, approximately 1/3 of length of styles; articulated to base of paraphysis. Styles ( Figs 8, 9) long and slender; apex chela-shaped, dorsal branch more slender, with median tooth on lateral inner margin, ventral branch more robust, with dorsal apical tooth. Paraphysis ( Fig. 10) long, almost twice the length of aedeagus; connecting anteroventral portion of connective to atrial region of aedeagus. Aedeagus ( Fig. 10) with tubular shaft bent dorsoanteriorly; apex acute; dorsal apodeme nearly as long as shaft; gonophore apical. Anal tube membranous, without processes.

Female unknown.

Etymology: The species name is a tribute to Dr. Ana Paula Marques-Costa, due to her contribution to the knowledge of Cicadellidae , especially Neocoelidiinae , and also due to a great friendship and for introducing the first author of this paper to the study of the group.

Notes: Paraphysiana marquescostae spec. nov. can be easily distinguished from P. diminuta by the characters of the male pygofer. The new species has a pair of inner dorsal processes ( Fig. 5) on the male pygofer, which is absent in P. diminuta . Furthermore, the inner ventral processes of the pygofer in P. marquescostae are curved dorsally and twisted apically, while in P. diminuta the inner ventral processes are approximately straight and not twisted.
