Ptiloneura hinestrozae González, Carrejo & Panche

( Figs 56–67 )

Diagnosis. Close to P. kogui n. sp., differing from it in having the posterior side sclerites of the hypandrium with the posterior projection short, not proximally wide, and rounded distally ( Fig. 59 ). Mesal endophallic sclerite narrow, with median posterior process conic as in P. cipeca n. sp. ( Fig. 61 ).

Male. Color. Body brown to ochre. Head pattern ( Fig. 58 ) with two brown bands from the inner border of each compound eye to the epistomal sulcus, enclosing the antennal fossae. Compound eyes black, ocelli hyaline, with ochre centripetal crescents. Vertex with small brown irregular areas. Postclypeus with ochre V-shaped area, light brown mesally. Anteclypeus and labrum pale brown. Genae light brown. Postgenae light brown. Antennae pale brown, flagellomeres with apices cream. Maxillary palps pale brown. Tergal lobes of mesothorax pale brown, tergal lobes of metathorax dark brown. Propleura and metapleura light brown, with ochre spots, mesopleura brown. Legs pale brown, coxae and trochanters with ochre spots; tibiae with dark brown areola in setal insertions. Wings hyaline, forewings with pterostigma dark brown, with a large hyaline area distally; a brown marginal band from R4+5 to distal half of 1A; the band shaped like narrow arcs, with hyaline fenestrae on each side of vein ends. Hindwings veins brown. Abdomen light brown, with ochre spots. Sclerites of hypandrium brown. Phallosome dark brown. Epiproct and paraprocts creamy, with ochre spots subcuticularly.

Morphology. Head ( Fig. 58 ) H/MxW: 1.45; large compound eyes, H/d: 2.90; IO/MxW: 0.74; vertex below the level of the upper border of the compound eyes; outer cusp of lacinial tips broad, with 8 denticles. Mx4/Mx2: 1.41. Forewings ( Fig. 56 ) L/W: 2.72; pterostigma: lp/wp: 5.00, elongate, wider in the middle; M six branched; areola postica: la/ha: 1.61, tall, apically rounded. Hindwings ( Fig. 57 ) l/w: 3.02; M four-branched. Hypandrium of five sclerites ( Fig. 59 ), central sclerite with tufts of long macrosetae on each side; posterior side sclerites with posterior projection short. Phallosome ( Fig. 61 ) Y-shaped anteriorly, side struts wide basally; external parameres elongate, with rounded apices, bearing small pores. Five endophallic sclerites. Anterior pair medium sized, broadly subquadrate. Lateral sclerites with wide distal area of internal margin convex, bearing teeth. Mesal sclerite transverse, with posterior processes conic, mesal sclerite processes elongate, basally wide, blunt apically; Paraprocts ( Fig. 60 ) oval, setae and spicules as illustrated; sensory fields with 24 trichobothria on basal rosettes. Epiproct ( Fig. 60 ) anteriorly convex, posteriorly rounded, with microspicules and setae as illustrated.

Female. Color. Body, head, legs, wings, epiproct and paraprocts as in the males. Pigmented area of subgenital plate U-shaped, arms dark brown, bridge pale brown ( Fig. 65 ). Gonapophyses: v1 hyaline with long light brown longitudinal band, v2+3 brown. IX sternum yellowish to cream, with small lateral brown spots.

Morphology. Head ( Fig. 64 ) H/MxW: 1.47; large compound eyes, H/d: 3.31; IO/MxW: 0.77; vertex at the same level as the upper border of the compound eyes; outer cusp of lacinial tips broad, with 7-8 denticles. Mx4/Mx2: 1.24. Forewings ( Fig. 62 ) L/W: 2.72; pterostigma: lp/wp: 4.84; M six-branched; areola postica: la/ha: 1.50, tall, apically rounded. Hindwings ( Fig. 63 ) l/w: 3.02; M four-branched. Subgenital plate ( Fig. 65 ) wide, apex rounded, with long and short setae. Gonapophyses ( Fig. 66 ): v1 elongate, slender and acuminate, with long and abundant spicules distally; v2+3 with anterior long and slender heel, with two macrosetae on v2; distal process long, acuminate, with long spicules on distal surface. Ninth sternum ( Fig. 66 ) of three distinct areas, sclerotized, cup-shaped, anteriorly wide, concave in the middle and convex laterally, anterior membranous area of convex margins as illustrated. Paraprocts ( Fig. 67 ) oval, elongate, with long and short setae distally. Sensory fields with 25 trichobothria on basal rosettes. Epiproct ( Fig. 67 ) triangular, elongate, posterior margin rounded, with long and short setae, mesal field with three macrosetae and short setae, as illustrated.
