Steleops caquetensis sp. nov.

( Figs 89–95 View FIGURES 89–95 )

Diagnosis. Belonging to group albertonetoi . Like S. ecuadorensis and S. garcialdretei it has forewing with Rs-M joined by a short transverse vein, compound eyes large and almost round, as in S. braziliensis and S. ecuadorensis , but it is different from this and the other species of the group by presenting only one reniform laminar structure, the other being poorly developed or vestigial, posterior pair of acuminate processes much smaller than anterior pair ( Fig. 94 View FIGURES 89–95 ), phallosome with aedeagus not projecting distally, phallobase basally widened ( Fig. 95 View FIGURES 89–95 ) and epiproct with spinous area in the posterolateral angle ( Fig. 92 View FIGURES 89–95 ).

Male. Color (in plate and 80% ethanol). Head ( Fig. 91 View FIGURES 89–95 ) brown, with darker and lighter areas on vertex, frons, genae and clypeus. Black to dark brown compound eyes. Forewings ( Fig. 89 View FIGURES 89–95 ) with pale brown spots, with four small spots in the cells r 3, r 5, m 1, y m 2. Pterostigma with brown apical spot, veins brown. Hindwings ( Fig. 90 View FIGURES 89–95 ) hyalines, veins brown. Epiproct and paraprocts light brown. Hypandrium brown. Legs pale brown.

Morphology. As in diagnosis, plus the following: Head ( Fig. 91 View FIGURES 89–95 ): H/MxW: 1.31; compound eyes large, H/D: 1.76; IO/MxW: 0.59. Vertex V–shaped wide, below upper level of compound eyes. Outer cusp of lacinial tips with three denticles; Mx4/Mx2: 1.19. Forewings ( Fig. 89 View FIGURES 89–95 ): L/W: 2.70. Pterostigma: lp/wp: 2.50, areola postica: al/ah: 1.55. Hindwings ( Fig. 90 View FIGURES 89–95 ): l/w: 2.98.). Hypandrium ( Fig. 94 View FIGURES 89–95 ) asymmetrical, with tongue-shaped medial band covered by very small papillae or spicules; with one large reniform laminar processes that bend toward the mesal line, with two pairs of thick tapered processes, the posterior pair much shorter, thinner and basally closer than the anterior pair, arms thick, curved inwards. Phallosome ( Fig. 95 View FIGURES 89–95 ) rhomboid, asymmetric, with poorly developed left paramere, the right one in the form of an apically rounded lobe, partially fused to the aedeagus and directed towards the right; aedeagus distally not projected. Phallobase projected, laminar and anteriorly rounded. Epiproct ( Fig. 92 View FIGURES 89–95 ) projected on the clunium, pyriform in dorsal view, with rounded posterior edge and anterior area with narrow projection. Paraprocts ( Fig. 93 View FIGURES 89–95 ) oval, with apical process almost as long as the body of the paraproct, straight and apically acuminate and short curved, sensory fields with 17 trichobothria on basal rosettes.
