Vinasco-Mondragón, Andrés Felipe, González-Obando, Ranulfo & García-Aldrete, Alfonso N., 2018, The species group Amabilis of the genus Euplocania Enderlein (Psocodea: Psocomorpha: Ptiloneuridae), Zootaxa 4444 (1), pp. 43-65 : 55

Euplocania manausensis n. sp. Male

Figs 37–42

Diagnosis. It is close to E. metensis n. sp., from which it differs by the robust mesal endophallic sclerites, 0.25 as wide as long.

Color (in 80% ethanol). Head ochraceous, with dark brown pattern as illustrated ( Fig. 39 ). Compound eyes black, ocelli hyaline, with ochre centripetal crescents. Forewings veins brown, with a dark brown spot at wing margin; first section of vein Rs, vein M and crossvein Rs-M dark brown. Pterostigma dark brown, with a hyaline round window at the lower angle ( Fig. 37 ). Hindwings hyaline, veins pale brown, with a small dark brown spot distally, except A2 ( Fig. 38 ). Hypandrium brown, with median longitudinal stripe dark brown. Paraprocts and epiproct pale brown, paraprocts with a dark brown semi-circular band bordering outer edge of sensory fields.

Morphology. Head ( Fig. 39 ): H/MxW: 1.48, H/d: 3.21, compound eyes large: IO/MxW: 0.42; H/D: 2.4. Vertex concave in the middle. Outer cusp of lacinial tip broad, with seven denticles. Forewings ( Fig. 37 ). L/W: 4.15, pterostigma elongate and projected towards R2+3, lp/wp: 3.47. Areola postica low, elongate, slanted posteriorly, with apex rounded, al/ah: 1.84. Hindwings ( Fig. 38 ): l/w: 2.88. Hypandrium convex posteriorly, posterior processes as illustrated ( Fig. 42 ) flanking a short median arch. Phallosome anteriorly V-shaped ( Fig. 41 ), external parameres membranous, with an inner, long and thin sclerotized bar. Lateral endophallic sclerites stout, wide anteriorly and narrowing posteriorly. Mesal endophallic sclerite transverse; posterior border sinuous with four small projections; anterior border sinuous, with antero-lateral corners projected; postero-median process long, stout, about twice as long the width of the sclerite. Paraprocts ( Fig. 40 ) broadly triangular, setose as illustrated, sensory fields with 28 trichobothria on basal rosettes. Epiproct wide, anteriorly convex, posteriorly rounded, setae as illustrated ( Fig. 40 ).

Measurements. FW: 4250, HW: 2950, F: 1225, T: 1800, t1: 770, t2: 90, t3: 130, ctt1: 25, IO: 470, D: 510, d: 350, IO/d: 1.34, PO: 0.69.
