Euplocania hutchingsi n. sp. Male

( Figs 16–22 )

Diagnosis. Belonging in species group amabilis of García Aldrete et al. (2013) and subgroup ariasi , of Vinasco- Mondragón et al. (2018). It is close to E. ariasi Vinasco-Mondragón, González & García Aldrete , differing from it by having the postero-lateral processes of the central sclerite of hypandrium curved inwards, with straight acuminate internal processes directed inwards, by having an acuminate projection on each side, anterior to each postero-lateral process, and in details of the phallosome endophallic sclerites, particularly the mesal sclerite, which has a small posterior projection in the middle (compare Figs 20 and 21 in this paper with Figs 5 and 6 in Vinasco- Mondragón et al. 2018).

Color (in 80% ethanol). Compound eyes black, ocelli hyaline, with ochre centripetal crescents, head pattern ( Fig. 16 ). Scape brown, pedicel yellow. Legs with coxae brown, trochanters and femora yellow, tibiae brown, distally dark brown; tarsomere 1 yellow with end dark brown, tarsomeres 2–3 dark brown. Forewings veins brown, with a dark brown spot at wing margin, a marginal pigmented band from R 4+5 to A 2 with two hyaline areas, boomerang shaped, on each side of vein ends at wing margin; Rs and crossvein Rs-M dark brown. Pterostigma dark brown, with a small pale brown area at lower angle ( Fig. 17 ). Hindwings ( Fig. 18 ), almost hyaline, with area limited by CuP brown pale brown, veins brown, each with a brown spot distally at wing margin.

Morphology. As in diagnosis, plus the following: Compound eyes without interommatidial setae ( Fig. 16 ). Outer cusp of lacinial tip broad, with five denticles ( Fig. 19 ). Forewing pterostigma angulate, projected in the middle towards Rs, almost triangular, areola postica tall, with round apex, slanted posteriorly, M with four primary branches ( Fig. 17 ). Hindwing Rs straight, R 2+3 and R 4+5 straight, M sinuous ( Fig. 18 ). Hypandrium of three sclerites, a large central sclerite, with sides sinuous, almost straight anteriorly, side sclerites almost triangular; setae as illustrated ( Fig. 20 ). Phallosome ( Fig. 21 ) with side struts basally fused, V-shaped, narrowing posteriorly, distally curved inwards and acuminate. External parameres U-shaped with a field of pores distally. Mesal sclerite narrow in the middle, widening at the ends, with a small posterior projection in the middle. Two pairs of endophallic sclerites, antero-mesal pair strongly sclerotized, V-shaped, with slender inner arms and stout outer arms; antero-lateral pair wide basally, with sides narrowing posteriorly, with acuminate apex. Paraprocts ( Fig. 22 ) almost elliptic, with a dense distal setal field; sensory fields with 27–28 trichobothria on basal rosettes. Epiproct ( Fig. 22 ) broad, with one concave area on each antero-lateral corner; sides converging to round posterior border, one macroseta on each side, other setae as illustrated.

Measurements (in microns). FW: 4137, HW: 2840, F: 1202, T: 1723, t1: 717, t2: 76, t3: 183, IO: 508, D: 443, d: 270, PO: 0.61.
