Euplocania ufrr sp. nov.

( Figs. 15-21 )

Male

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. bujariensis in the general shape of the hypandrium, especially by having postero-lateral processes of the central sclerite of hypandrium as long as its antero-posterior length, instead the anteroposterior length of the basal part of the hypandrium two or three times longer than the length of the its postero-lateral processes as occurs in the other six species included in this subgroup and by having the lateral posterior projections of the hypandrium with the apex of the inner margin not acuminate. Differing from E. bujariensis by having pterostigma without a small hyaline window at lower angle, by having basal part of the hypandrium semi oval instead of sub square as in E. bujariensis , by having distal part of postero-lateral processes of the hypandrium about three times longer than it is wide, rather than just twice as long as it is wide as in E. bujariensis , and by having mesal endophallic sclerite without postero-lateral processes, with median process widening distally (compare Figs. 16, 19 and 20 in this paper with figs. 2, 6 and 7 in Silva-Neto et al., 2019).

Color (in 80% ethanol): Compound eyes black, ocelli hyaline, with ochre centripetal crescents, head pattern ( Fig. 15 ). Scape and pedicel dark brown, f1-f3 yellow. Mx4 yellow with apex brown. Legs with coxae, trochanters and femora pale yellow, tibiae pale brown, with apex dark brown; tarsomere 1 yellow, tarsomeres 2-3 dark brown. Forewing veins brown, with a dark brown spot at wing margin; a marginal pigmented band from R₄₊₅ to A2 with two hyaline areas, boomerang shaped, on each side of veins, distally at wing margin, from R₄₊₅ to Cu1a; Rs and crossvein Rs-M dark brown. Pterostigma completely dark brown ( Fig. 16 ). Hindwings ( Fig. 17 ), almost hyaline, veins brown, each with a brown spot distally at wing margin.

Morphology: Head with vertex concave in the middle, slightly above the level of the upper border of the compound eyes, these without interommatidial setae ( Fig. 15 ). Outer cusp of lacinial tip broad, with five denticles ( Fig. 18 ). Forewing pterostigma angulate, projected in the middle towards Rs, areola postica tall, with round apex; Rs stem almost straight, R₂₊₃ and R₄₊₅ sinuous; M stem slightly concave proximally, then almost straight, with four primary branches, M₁ almost straight, M₂-M₄ sinuous ( Fig. 16 ). Hindwing Rs straight, R₂₊₃ straight, R₄₊₅ slightly concave proximally, then almost straight, M stem sinuous ( Fig. 17 ). Hypandrium of three sclerites, a large central sclerite, basally semi-oval, with a small acuminate projection on each side, anterior to each postero-lateral processes, these last with distal part about three times longer than it is wide, with the apex of the inner margin not acuminate, setae as illustrated ( Fig. 19 ). Phallosome ( Fig. 20 ) with side struts basally fused, V-shaped, widening in the middle and narrowing at the ends, distally curved inwards. External parameres U-shaped with a field of pores in the middle. Mesal sclerite wide, strongly sclerotized, tripartite into three equal parts, transversely y-shaped, with a central projection in the middle, widening at the end. Two pairs of endophallic sclerites, an antero-mesal pair fused in the middle of the phallosome, giving rise to a type of second mesal sclerite, anteriorly wide, triangular, posteriorly narrowing, V-shaped, ending in the possible fusion zone, it with a small acuminate projection; an antero-lateral pair wide basally, with sides narrowing posteriorly, with apex truncate. Epiproct wide basally, with sides converging to triangular posteri- or border, three setae mesally, other setae as illustrated ( Fig. 21 ). Paraprocts broad, wide basally, posteriorly narrowing at the end, with apex straight, sensory fields with 30-31 trichobothria on basal rosettes, setae as illustrated ( Fig. 21 ).
