Euplocania pseudopictaoides n. sp. Male

( Figs 23–30 )

Diagnosis. Belonging in species group amabilis , of García Aldrete et al., (2013) and subgroup picta , of Vinasco- Mondragón et al., (2018). It is close to E. pictaoides García Aldrete , by having two mesal endophallic sclerites instead of one as in the other species of its group, but differing from it by the shape of the postero-lateral processes of the central sclerite of the hypandrium, by details of the phallosome endophallic sclerites and by having a forewing with marginal pigmentation from pterostigma to A 2, instead from R 4+5 to A2 (Compare Figs 24, 27 and 28 in this paper with Figs 10, 14 and 16 in García Aldrete 1998).

Color (in 80% ethanol). Compound eyes black, ocelli hyaline, with ochre centripetal crescents, head pattern ( Fig. 23 ). Scape brown, pedicel dark brown. Legs with coxae brown, trochanters and femora pale yellow, tibiae brown with apex dark brown; tarsomere 1 yellow, distally dark brown, tarsomeres 2–3 dark brown. Forewings veins brown, with a dark brown spot at wing margin, a marginal pigmented band from pterostigma to A 2, with two hyaline areas from R 4+5 to areola postica, boomerang shaped, on each side of vein ends at wing margin; Rs and crossvein Rs-M dark brown. Pterostigma dark brown ( Fig. 24 ). Hindwings ( Fig. 25 ), almost hyaline, with area limited by CuP brown pale brown, veins brown, each with a brown spot distally at wing margin, except Cu 1a.

Morphology. As in diagnosis, plus the following: Head with vertex concave in the middle, slightly above the level of the upper border of the compound eyes; these without interommatidial setae ( Fig. 23 ). Outer cusp of lacinial tip broad, with five denticles ( Fig. 26 ). Forewing pterostigma angulate, projected in the middle towards Rs, almost triangular, areola postica tall, wide, with round apex, slanted posteriorly, M with four primary branches ( Fig. 24 ). Hindwing Rs, R 2+3 and R 4+5 straight, M sinuous ( Fig. 25 ). Hypandrium of three sclerites, a large central sclerite with sides sinuous, straight anteriorly, with a median V-shaped concavity, claw-shaped acuminate internal processes on the posterior projections, these with a field of small spines on each, side sclerites triangular, setae as illustrated ( Fig. 27 ). Phallosome ( Fig. 28 ) with side struts basally fused, V-shaped, narrowing posteriorly and distally almost triangular with a small projection acuminate and curved inwards. External parameres U-shaped with a field of pores in the middle, with a small acuminate projection in its posterior outer margin. Two mesal sclerites, strongly sclerotized, anterior V-shaped, narrow in the middle, widening at the ends, anteriorly stout, almost elliptical and posteriorly almost triangular; posterior sclerite transverse, widest in the middle, narrowing to the sides, anteriorly with two small projections on each side and with a long posterior projection in the middle, ending in a rounded apex. A pair of antero-lateral endophallic sclerites, almost elliptic, wide basally, with sides narrowing posteriorly with acuminate apex. Epiproct wide, almost straight anteriorly, trapeziform, with three mesal setae near anterior border, setal fields on posterior edge and one macroseta on each side ( Fig. 29 ). Paraprocts ( Fig. 30 ) broad, almost elliptic, sensory fields with 31–32 trichobothria on basal rosettes, setae as illustrated ( Fig. 30 ).
