Triplocania paranaensis n. sp. (Male).

(Figs 103–109)

Diagnosis. Differing from the known species of Triplocania, in having the central piece of the hypandrium uniquely shaped, wide, anteriorly convex, with antero-lateral processes directed posteriorly, and distal processes acuminate, directed outwards, each bearing a row of four-five setae on the inner border near the middle.

Color. Compound eyes black, ocelli hyaline, with ochre centripetal crescents; head pattern (Fig. 103). Scape pale brown, pedicel pale yellow; f1–f3 pale yellow, with apex white. Femora pale yellow; tibiae yellow; tarsomeres 1–3 pale yellow. Forewing with a brown marginal band from R2+3 to CuA2;a brown area along CuA to posterior end of CuP, a dark brown spot at confluence of CuP-1A, with a brown area limited by CuP proximally at wing margin; pterostigma with brown bands anteriorly and posteriorly; veins brown (Fig. 104). Hindwing mostly hyaline, with brown spots on ends of R4+5 and M; and a small brown area on CuP at wing margin; veins brown (Fig. 105).

Morphology. Compound eyes without interommatidial setae. Outer cusp of lacinial tip broad, with five denticles (Fig. 106). Forewing pterostigma basally narrow, wider in the middle; Rs stem slightly convex proximally, then almost straight, R2+3 almost straight, R4+5 convex in the middle, M stem concave proximally, then almost straight, M1 convex proximally, then almost straight, M2 sinuous, M3 almost straight; areola postica tall, slightly slanted posteriorly, with round apex, 2A not reaching the wing margin. Hindwing Rs straight, R2+3 straight, R4+5 almost straight, M sinuous. Hypandrium of three sclerites, a large central sclerite, anterioly convex, with small concave areas; antero-lateral corners curved, narrowing posteriorly, with two stout posterior projections, acuminate, directed outward, leaving between them a concavity; flanked by large, irregular side sclerites; setae as illustrated (Fig. 107). Phallosome (Fig. 108) with side struts independent, V shaped, anteriorly acuminate, fused posteriorly to slender external parameres, curved inwards, with round apex, bearing a field of pores distally; four pairs of endophallic sclerites, anterior pair transverse, elongate, inner ends rounded, almost together in the middle, distally curved and acuminate; antero-lateral pair sinuous, elongate, narrowing distally, curved outwards; mesolateral pair, basally wide, narrowing and curving abruptly outwards, distally acuminate; postero-mesal pair, broad, small, with six small acuminate extensions. Epiproct wide basally, with sides converging towards a straight apex, three setae in mesal position, other setae as illustrated (Fig. 109). Paraprocts broad, narrowing posteriorly, rounded, sensory fields with 27 trichobothria on basal rosettes, setae as illustrated (Fig. 109).
