Description

MEASUREMENTS. Total length: male 10.2–11.5 mm (n =21); female 12.3–14.5 mm (n=20).

COLORATION. Pale yellow to yellow ( Fig. 6C–F ). Crown ( Fig. 2A ) pale yellow, with circular black spot behind each ocellus, adjacent to posterior margin; anterior margin with three dark maculae, one medially and two in front of ocelli. Face ( Figs 2B , 3A ) pale yellow to yellow; frons with about ten pairs of dark bands over muscular impressions, dorsal portion with small dark punctuations; epistomal and frontogenal sutures black; lorum with dark subtriangular macula adjacent to lateral margin of clypeus; clypeus with central dark macula and apical margin black; gena with three black maculae that may be interconnected, forming large spot in some specimens: one adjacent to antennal pit, one adjacent to inner corner of compound eye, and one adjacent to lorum base. Pronotum ( Fig. 2A ) with small dark punctures except near anterior margin, behind eyes. Mesonotum ( Fig. 2A ) with ringed black maculae near lateral corners; in lateral view ( Fig. 2C ), lateral lobe of pronotum with large black spot, anepisternum with small black spot. Forewing ( Fig. 2D ) pale yellow, translucent, with yellow-cream areas on basal twothirds; numerous small black spots throughout surface and several larger black spots on apices of anal veins, along costal margin, over crossveins, and apical margin. Legs ( Fig. 6D, F ) pale yellow with scattered dark maculae; tarsus of pro- and mesothoracic legs black.

HEAD AND THORAX. External morphological characters as in generic description.

MALE TERMINALIA. Sternite VIII ( Fig. 2E ) strongly produced posteriorly, about 1.6 times as long as wide; lateral margins converging towards apex, posterior margin broadly rounded. Valve subrectangular, three times as wide as long; posterior margin shallowly excavated medially. Pygofer in lateral view ( Fig. 2F ) elongate, about 2.1 times as long as maximum height; apex rounded; macrosetae distributed only on apical half; basiventral inner process ( Fig. 2F ) strongly sclerotized, long and thin, almost reaching pygofer apex and contiguous to ventral margin, apical fourth curved dorsally; in ventral view ( Fig. 2G ), process broadened preapically, with short preapical tooth on external side, apex acute. Subgenital plate in lateral view ( Fig. 2F ) not produced posteriorly as far as pygofer apex; in ventral view ( Fig. 2H ) long and narrow, about 6.4 times longer than wide; lateral margins parallel; apex abruptly rounded. Connective ( Fig. 2I ) approximately one-fourth of length of style; stalk longer than wide; arms short, slightly wider than stalk; dorsal keel developed. Style in dorsal view ( Fig. 2I ) with outer lobe developed and rounded; in lateral view ( Fig. 2J ), broadened on apical two-thirds and tapering towards apex; ventral margin with few denticles at median third; apex acute and curved dorsally. Aedeagus ( Fig. 2K–L ) with preatrium long; dorsal apodeme projected dorsally; shaft elongated and tubular, curved posterodorsally, expanded apically; apex bilobed, with pair of small apical spines.

FEMALE TERMINALIA. Sternite VII ( Fig. 3B–C ) 2.3 times as wide as long; posterolateral borders rounded, posterior margin slightly excavated medially. Internal sternite VIII membranous. Pygofer ( Fig. 3D ) elongate, about 1.8 times as long as maximum height; apex rounded; macrosetae distributed near apex and ventral margin. First valvifer ( Fig. 3E ) subquadrate. First valvula of ovipositor ( Fig. 3E ) slightly curved dorsally, about 9.6 times as long as high; with approximately same height along its entire length; dorsal sculptured area beginning on basal third, its apical portion ( Fig. 3F ) strigate; blade apex acute. Second valvifer ( Fig. 3I ) higher than long. Second valvula of ovipositor ( Fig. 3G ) slightly higher apically, approximately 9.5 times longer than maximum height; apical portion ( Fig. 3H ) of dorsal margin with about seven small and rounded teeth; blade apex tapered and acute. Gonoplac ( Fig. 3I ) 4.7 times as long as high; dorsoapical and ventroapical margins convergent apically; dorsoapical margin short; ventral margin with few short setae mainly near apex; apex subacute.

Remarks

Male specimens collected from different localities show a variation in the shape of the apical portion of the ventral process of pygofer, which may be more curved or straighter, more dilated or slightly thinner. In addition, some specimens have two conspicuous and rounded black spots over crossveins of discal cells of forewing. However, remaining structures of the male terminalia and shape of the female sternite VII are invariable and we thus consider these variations as intraspecific.

Specimens of Fulana brasiliensis gen. et sp. nov. were mainly collected in areas of Atlantic Forest, at altitudes that vary from 50 to 1960 m above sea level. A putative second species of the new genus, known only from female specimens from the Brazilian Amazon Rain Forest, State of Amazonas, Manaus, was studied but will not be described until male specimens become available. This undescribed species is similar to F. brasiliensis gen. et sp. nov. in all aspects of the external morphology and female terminalia described herein. However, it can be distinguished by its larger size (15.5–15.8 mm); head in ventral view with fewer black maculae on face (lorum with small spot adjacent to lateral margin of clypeus, frons with punctuations and a semi-circular macula near anterior margin of crown, and antennal pits black); and sternite VII more deeply excavated medially.
