Triplocania diamantina sp. nov. Male ( Figs. 8-14 )

Diagnosis: Forewing pterostigma brown, with a light- er triangular spot in the middle; a pale brown marginal band from R₄₊₅ to the areola postica, a brown spot-on vein ends, from R₂₊₃ to Cu1b, and a brown area distally of 1A ( Fig. 9 ). Central piece of the hypandrium anteriorly with a small projection in the middle, posteriorly with two robust projections, with the inner border strongly sclerotized, with two inward-facing processes ( Fig. 12 ). Phallosome ( Fig. 13 ) with side struts basally fused, U-shaped, not fused to external parameters, mesal sclerite wide, W-shaped, anteriorly strongly sclerotized, with a median concavity, narrow in the middle, then widening, with two stout posterior processes, distally curved inward and with blunt apices. Lateral endophallic sclerites bow-shaped, anteriorly wider, narrowing posteriorly, with apices dilated, bent outward, acuminate.

Color: Compound eyes black, ocelli hyaline, with ochre centripetal crescents, head pattern ( Fig. 8 ). Scape pale brown, pedicel pale brown, f1-f3 pale brown, with apices white. Mx4 pale brown. Coxae pale brown, trochanters pale brown in the middle and lighter at the ends, femora proximally pale brown,tibiae pale brown; tarsomeres 1-3 brown. Forewings with pterostigma brown, veins brown ( Fig. 9 ). Hindwing hyaline; veins brown ( Fig. 10 ).

Morphology: Head vertex slightly concave in the middle, below the level of the compound eyes’ upper border, these without interommatidial setae ( Fig. 8 ). Outer cusp of lacinial tips broad, with six denticles ( Fig.11 ). Forewing pterostigma wider in the middle, narrow anteriorly; areola postica wide, slanted posteriorly, apically round; M stem slightly concave, M₁ almost straight, M₂ slightly sinuous, M₃ proximally convex, then almost straight to the end, R s stem convex, R₂₊₃ proximally straight then distally concave, R₄₊₅ slightly concave proximally, then almost straight ( Fig. 9 ). Hindwing R s stem straight, R₂₊₃ straight, and R₄₊₅ slightly concave proximally,then almost straight, M stem sinuous, proximally slightly convex ( Fig. 10 ). Hypandrium ( Fig. 12 ) of three sclerites with central piece anteriorly with two less sclerotized circular parts and bristles distributed over the surface, a small projection in the middle, also round. Phallosome ( Fig. 13 ). Epiproct concave in connection with the clunium, obtuse on the sides, almost straight at the apex, with three mesal macrosetae ( Fig. 14 ). Paraprocts broad, broadly triangular, setose as illustrated; sensory fields with 33 trichobothria on basal rosettes ( Fig. 14 ).
