Euplocania maraca sp. nov.

( Figs. 8-14 )

Male

Diagnosis: Belonging in species group amabilis of García Aldrete et al. (2013) and subgroup manausensis of Vinasco-Mondragón et al. (2018). Differing from the known species of this subgroup, in having postero-lateral processes of the central sclerite of hypandrium anteriorly distinctly bulged, not sinuous, leaving between them two small triangular projections, by having mesal endophallic sclerite with median process narrowing distally, almost triangular, with postero-lateral corners projected, these almost rectangular, posteriorly with a slight indentation each.

Color (in 80% ethanol): Compound eyes black, ocelli hyaline, with ochre centripetal crescents, head pattern ( Fig. 8 ). Scape dark brown, pedicel yellow, f1 pale yellow. Mx4 yellow with apex dark brown. Legs with coxae, trochanters and femora brown, tibiae yellow with apex 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 R₄₊₅ to A2 with two hyaline areas, boomerang shaped, on each side of the distal ends of the veins at wing margin;Rs and crossvein Rs-M dark brown, R₂₊₃ with a brown spot distally at wing margin. Pterostigma dark brown, with a hyaline window, almost elliptical at lower angle ( Fig. 9 ). Hindwings ( Fig. 10 ), almost hyaline, veins brown, each with a brown spot distally at wing margin.

Morphology: Compound eyes without interommatidial setae ( Fig. 8 ). Outer cusp of lacinial tip broad, with six denticles ( Fig. 11 ). Forewing pterostigma angulate, almost triangular, areola postica tall, with round apex, slanted posteriorly, Rs stem almost straight, R₂₊₃ and R₄₊₅ sinuous;M stem slightly concave proximally, then almost straight, with four primary branches, M₁ straight, M₂-M₄ sinuous ( Fig. 9 ). Hindwing Rs and R₂₊₃ straight, and R₄₊₅ convex in the middle, M sinuous ( Fig. 10 ). Hypandrium of three sclerites, a large central sclerite with postero-lateral processes anteriorly distinctly bulged, not sinuous, leaving between them two small triangular projections; side sclerites large, broadly, posteriorly forked ( Fig. 12 ). Phallosome ( Fig. 13 ) with side struts basally fused, V-shaped, widening posteriorly and distally almost triangular. External parameres stout, K-shaped, with pores in outer arm. Two pairs of endophallic sclerites, antero-mesal pair strongly sclerotized, rounded basally, almost square posteriorly, with apex slightly forked; an antero-lateral pair stout, elongate, proximally wide, narrowing posteriorly, blunt ended. Epiproct wide basally, with sides converging to straight posterior border, three setae mesally, other setae as illustrated ( Fig. 14 ). Paraprocts broad, wide basally, posteriorly narrowing at the end, with apex rounded, sensory fields with 30-31 trichobothria on basal rosettes, setae as illustrated ( Fig. 14 ).

Measurements (in microns): FW: 4539, HW: 2915, F: 1342, T: 1846, t1: 712, t2: 98, t3: 149, f1: 528, Mx4: 320, IO: 645, D: 476 d: 327, PO: 0.68.

Material examined: Holotype male (INPA). BRAZIL. Roraima. Alto Alegre. EstaÇÃo ecológica Maracá. 03°21′59″N, 61°26′04″W. 10-25.xii. 2015. Malaise grande. Rede Bia. R. Boldrini & J.A. Rafael.

Etymology: The specific epithet is given to this species as a noun in apposition and refers to the ecological station Maraca in Brazilian state of Roraima, where the holotype was collected.
