Head pattern ( Fig. 21). Compound eyes black, ocelli with ochre centripetal crescents. Clypeus, vertex and labrum pale brown. Genae with longitudinal dark brown stripes. Antennae brown. Forewings veins brown, with a dark brown spot at wing margin surrounded by a clear window. Pterostigma dark brown ( Fig. 19). Hindwings hyaline, veins brown, with a brown spot at wing margin ( Fig. 20). Centralsclerite of hypandrium pale brown, with median Y-shaped dark brown area; postero-lateral processes ochraceous with clear border. Epiproct pale, paraprocts with a dark semi-circular band partially limiting the sensory fields.   Morphology. Head ( Fig. 21): H/MxW: 1.49, vertex concave; compound eyes large, H/d: 3.06; H/D: 2.03; IO/ MxW: 0.47. Outer cusp of lacinial tip broad, with six denticles. Forewings ( Fig. 19): L/W: 2.54. Pterostigma: lp/ wp: 3.53, areola postica with rounded apex: al/ah: 1.96. Hindwings ( Fig. 20): l/w: 2.77. Centralsclerite of hypandrium convex anteriorly with a slight notch in the middle, deeply concave posteriorly, latero-posterior processes distally curved inward, side sclerites triangular ( Fig. 24). Phallosome ( Fig. 23) anteriorly V-shaped, with slender side struts; external parameres membranous, distally broad and rounded; two pairs of endophallic sclerites, and one posterior transverse mesal sclerite, the latter one with two pairs of postero-lateral process and one pair of antero-lateral process, making the sclerite looks like two horses. Paraprocts ( Fig. 22) almost elliptic, with a dense setal field distally; sensory fields with 27 trichobothria on basal rosettes. Epiproct ( Fig. 22) broad, triangular, rounded posteriorly, setal field on sides and anteriorly; two pairs of large setae, one median and one preapical.  Measurements.FW: 4500, HW: 2975, f1: 960, IO: 520, D: 540, d: 360, IO/d: 1.44, PO: 0.66.    Specimenstudied. Holotypemale.  BRAZIL. Pará,  Rio AraguaiaS.Cenuldo e Conceicudo, Araguaia. 08°20’58.92’’S: 49°18’31.32’’W.   15 m.  XI.1982. J.
