Euplocania uariniensis n. sp. Male

( Figs 39–46 )

Diagnosis. Belonging in species group marginata , of García Aldrete et al. (2013). Differing from E. marginata New & Thonton by having the central sclerite of the hypandrium convex anteriorly, with long setae on the posterior corners, with a median stout posterior process, narrowing distally, apically straight, underlaid by a bifid posterior process, each arm distally curved outwards.

Color (in 80% ethanol). Compound eyes black, ocelli hyaline, with ochre centripetal crescents, head pattern ( Fig. 39 ). Scape and pedicel brown, f1-f3 pale brown. Legs with coxae and trochanters brown, femora pale brown; tibiae proximally dark brown, then pale brown; tarsomere 1 pale brown, tarsomeres 2–3 brown. Forewings veins brown, a wide, marginal pigmented band from R 4+5 to CuP, with a small, hyaline area on each side of vein ends, at wing margin, from M 1 to M 4; Rs and crossvein Rs-M dark brown. Pterostigma peripherally pale brown, with small irregular brown spots ( Fig. 40 ). Hindwings with a homogeneous brown band from R 4+5 to A 1; veins brown ( Fig. 41 ).

Morphology. As in diagnosis, plus the following: Head vertex emarginate; compound eyes without interommatidial setae ( Fig. 39 ). Outer cusp of lacinial tip broad, with four denticles ( Fig. 42 ). Forewing pterostigma basally narrow, wider in the middle, narrowing posteriorly, areola postica tall, wide, with round apex, slanted posteriorly, M with four primary branches ( Fig. 40 ). Hindwing Rs, R 2+3 and R 4+5 straight, M sinuous ( Fig. 41 ). Hypandrium of three sclerites, side sclerites wider in the middle, narrowing at the ends and anteriorly with apex rounded, distally acuminate, setae as illustrated ( Fig. 43 ). Phallosome ( Fig. 44 ) with side struts basally fused, U-shaped, narrowing posteriorly and distally acuminate. External parameres stout, golf club-shaped, with a field of pores on the outer margin. Mesal sclerite wide, strongly sclerotized, anteriorly straight, with two projections on the posterior corners, stout, triangular. Two pairs of endophallic sclerites, an antero-mesal pair, small, strongly sclerotized, with three acuminate processes on inner margin; an antero-lateral pair, elongated, curved, with apex rounded and distal inner margin square. Epiproct ( Fig. 45 ) broad, with one concave area on each antero-lateral corner; sides converging to triangular posterior border, three mesal setae near anterior border, setal fields on posterior edge and one macroseta on each side. Paraprocts almost triangular; sensory fields with 33–34 trichobothria on basal rosettes, setae as illustrated ( Fig. 46 ).
