Fidicinoides besti Boulard and Martinelli, 1996

Head ( Fig. 1A ): lateral ocelli and medial ocellus situated on a black transverse irregular shaped band which extends to the base of the antennae and vertex; median ocellus in a sub-frontal position; distance between lateral ocelli nearly two and half times the distance that separates them from the corresponding eyes; salient eyes, rounded, oblique, with joined sub-ocular marks; postclypeus dorsal portion short and arched; postclypeus face distinctly arched, ochre, with nine dark transverse ridges on both sides of the medial furrow; black anteclypeus; rostrum brownish, long, with the apex reaching the base of the hind trochanters.

Thorax ( Fig. 1A ): pronotum longer than head; with four shallow furrows; lateral angle of pronotal collar poorly developed and brownish; mesonotum light brownish, with submedian sigilla dark brown well-defined and comma-shaped; the lateral sigilla light brown; a transverse, irregular-shaped stripe and two small black punctiform marks, above the cruciform elevation; cruciform elevation not very long, flattened and with the back apices short, rounded and close together ( Fig. 1A ); operculum very short, in small arched, ochre-coloured lamina.

Abdomen ( Fig. 1B ): a little shorter than the distance from the vertex to the back apices of the cruciform elevation; broad base, not tapering towards the last abdominal segment; ochre tergites; timbal cover dorsally short; sternites ochre, including the last abdominal segment; male sternite VIII twice as long as wide, with anterior margin almost straight, lateral margin oblique, and the posterior margin invaginated ( Fig. 1D ).

Forewing ( Fig. 1C ): hyaline; light brown fumose on the apical area; forewing with blackened basal cell; costal vein relatively short and ochre; veins ochre, becoming brownish in the apical area; the extremities of the veins with dark brown markings on both sides, and with deep brown infuscation on the radial and radiomedial crossveins; ambient vein dark brown; apical area octoloculate.
