Clinonana rafaeli Engel et Takiya sp. nov.

( Figs. 1 D, 6)

Measurements in mm (ɗ holotype). Total length: 16.0. Crown median length: 1.1. Pronotum median length: 2.5. Pronotum largest width: 7.2. Mesonotum largest width: 4.0. Mesonotum median length: 4.3.

External morphology. Crown ( Figs. 1 D, 6A) median length three-tenths of interocular (ratio= 0.34) and transocular width (ratio= 0.26). Pronotum ( Figs. 1 D, 6A) largest width 2.9 times median length; largest width 1.8 times largest mesonotum visible width. Mesonotum ( Figs. 1 D, 6A) length 1.2 times longer than combined mesal length of crown and pronotum. Other characteristics as in generic description.

Male genitalia. Styles ( Figs. 6 D, E) in lateral view with median concavity on ventral margin. Aedeagus ( Figs. 6 G, H) shaft preatrium pair of processes extending only until two-thirds of shaft length.

Female unknown.

Notes. Clinonana rafaeli sp. nov. is very similar to C. mirabilis in external morphology and male genitalia. Both species are smaller and have a less laterally expanded pronotum ( Figs. 1 C, D, 4A, 6A) than C. impensa ( Figs. 1 B, 3A). The new species differs from C. mirabilis by the following male genital characters: style in lateral view with ventral concavity in median portion ( Fig. 6 E, arrow); and aedeagal shaft thinner than in C. mirabilis , with preatrium basal processes extending only two-thirds length of shaft ( Figs. 6 G, H). In C. mirabilis the basal processes reach the apex of the aedeagus shaft.

Etymology. The new species epithet is in honor of the dipterist Dr. José Albertino Rafael (INPA), who coordinated projects including field work in the Brazilian Amazon which made possible the collection of specimens of Clinonana and many other leafhoppers by the junior author, besides being responsible for the collection of about half of specimens studied herein.

Material examined. Holotype, Brazil: Rondônia: ɗ, Porto Velho, Campus UNIR, 8°50'4" S 63°56'35" W, 17 IV 2006 (F. F. Xavier & J. A. Rafael), (INPA).
