Fidicinoides duckensis Boulard and Martinelli, 1996

Head ( Fig. 3A ): lateral ocelli and medial ocellus situated on an irregular-shaped broad black mark which extends to the vertex, not extending to the base of the antennae; median ocellus in a frontal position; distance between the lateral ocelli nearly twice the distance that separates them from the corresponding eyes; eyes salient and oblique, with discrete sub-ocular marks; long postclypeus dorsal portion, brownish and slightly arched; postclypeus face distinctly arched, ochre, with nine transverse ridges with black and light brown markings on both sides of the black medial furrow; black anteclypeus; rostrum ochre, long, with apex reaching the insertion of the hind femur.

Thorax ( Fig. 3A ): pronotum longer than head; lateral angle of pronotal collar poorly developed; mesonotum ochre, with soot black markings; lateral sigilla light coloured triangular-shaped outer markings, the base being two brownish irregular-shaped marks near the pronotum, central area colourless and two small marks at the apices; submedian sigilla triangular, broad, short and black, an irregular-shaped mark and two black punctiform marks above the cruciform elevation; cruciform elevation not very long, with posterior apices pointed and close together ( Fig. 3A ); operculum with short lamina, broad, arched, ochre-coloured lamina, with dark brown markings on the outer side.

Abdomen ( Fig. 3B ): a little shorter than the distance covered from the vertex to the back apices of the cruciform elevation; base wide, tapering in the direction of the last abdominal segment; brown and black tergites covered with golden hairs; timbal cover arched, dark brown; sternites brown, sparsely covered with golden and black hairs; male sternite VIII nearly twice as long as wide, with the front and side margins slightly concave and the back one having a half moon-shaped invagination, and the apices close together ( Fig. 3D ).

Forewing ( Fig. 3C ): hyaline; light brown fumose on the apical area; forewing with basal cell partially opaque and ochre coloured, costa long and of the same colour; veins ochre turning brown in the apical area, the extremities of the veins with fumose brown markings on both sides; infuscation on the radial and radiomedial crossveins and the ambient vein, slightly marked brown; apical area octoloculate.
