Euplocania tocantina  n. sp. Male

Figs 55–60 View Figure

Diagnosis. It is close to E. badonneli New & Thornton  , E. equorum  n. sp., and E. katios  n. sp., differing from them by having the central sclerite of hypandrium elongate, with stout, straight posterior processes, and by the shape of the mesal endophallic sclerite ( Fig. 59 View Figure ).

Color (in 80% ethanol). Head pattern ( Fig. 57 View Figure ). Compound eyes black, ocelli with ochre centripetal crescents. Labrum pale brown. Genae with dark brown stripes. Antennae pale brown. Maxillary palps brown, Mx4 distally dark brown. Forewings veins brown, with a dark brown spot at wing margin and a clear window surrounding it. Pterostigma dark brown ( Fig. 55 View Figure ). Hindwings hyaline, with pale brown veins, except Cu, A2 and stem of R which are brown, each vein with a brown spot at wing margin ( Fig. 56 View Figure ). Central sclerite of hypandrium pale brown, with median Y-shaped dark brown mark. Postero-lateral processes ochre, with dark brown sides. Epiproct pale brown, paraprocts with dark brown semi-circular band on outer border of sensory fields.

Morphology. Head ( Fig. 57 View Figure ): H/MxW: 1.4; compound eyes large, H/d: 3.01; H/D: 2.45; IO/MxW: 0.46. Outer cusp of lacinial tip broad, with seven denticles. Forewings ( Fig. 55 View Figure ): L/W: 2.41. Pterostigma: lp/wp: 3.71, areola postica tall, slanted posteriorly, apex round: al/ah: 1.98. Hindwings ( Fig. 56 View Figure ): l/w: 2.7. Central sclerite of hypandrium convex anteriorly, deeply concave posteriorly, side sclerites triangular ( Fig. 60 View Figure ). Phallosome ( Fig. 59 View Figure ) anteriorly V-shaped, external parameres membranous, distally broad, rounded and sclerotized, bearing 2–3 pores on each; two pairs of endophallic sclerites, and one posterior transverse mesal sclerite ( Fig. 59 View Figure ); mesal sclerite with two posterior projections as long as 0.85 times the width of mesal sclerite, with enlarged internal border forming a sheet that goes throw below the sclerite and anteriorly to this, the sheet in its anterior projections curved outward. Paraprocts ( Fig. 58 View Figure ) broadly elliptic, with a dense setal field distally; sensory fields with 28 trichobothria on basal rosettes. Epiproct ( Fig. 58 View Figure ) broadly triangular, straight anteriorly and rounded posteriorly, setae as illustrated.

Measurements. FW: 4225, HW: 3100, f1: 800, Mx4: 240, IO: 470, D: 500, d: 340, IO/d: 1.38, PO: 0.68.

Specimen studied. Holotype male. BRAZIL. Pará, Parauapebas , Serra Norte. 06°05’03.1”S  : 50°10’35.5’’W. XI.1982. Michael Miles. Light trap. INPA.

Etymology. The specific name, a noun in apposition, makes reference to the big Brazilian river Tocantins ("toucan's beak", in Tupi language).
