Ptiloneura timancoi Carrejo, González & García Aldrete. Male

( Figs 98–103 )

Diagnosis. Related to P. otunensis n. sp., differing from it in having the central sclerite of the hypandrium with five posterior processes, two lateral and three median ones, the central one bottle shaped and more elongate than the two side ones, lateral processes wide based, pointed, not bifurcated ( Fig. 101 ). Endophallic sclerites different, particularly the mesal one ( Fig. 103 ) (see above under P. otunensis ).

Color. Body dark brown. Head pale brown, with dark brown spots ( Fig. 100 ), two oblique ochre bands, from the inner margin of each compound eye to the epistomal sulcus, surrounding the antennal fossae. Compound eyes black; ocelli hyaline, with ochre centripetal crescents. Vertex pale brown, with ochre central and lateral bands. Postclypeus with oblique ochre slender bands on each side, pale brown in the middle; clypeus brown; labrum brown in the middle, with sides pale brown. Genae dark brown. Postgenae cream to yellowish. Antennae: scape and pedicel pale brown, flagellomeres pale brown, with apices cream. Maxillary palps pale brown, Mx4 dark brown. Pronotum ochre. Tergal lobes of meso- and metathorax dark brown. Thoracic pleura light brown, with large ochre spots. Legs: fore-, middle coxae and trochanters pale brown, with ochre spots basally; hind coxae, trochanters and femora cream, femora with apical small ochre spots; tibiae and tarsi pale brown. Forewings hyaline, with a marginal brown band from R4+5 to distal end of 1A, pterostigma dark brown, with a large hyaline area on the lower angle; veins brown, with a brown spot at wing margin. Hindwings hyaline, veins brown. Abdomen light brown to cream, with ochre spots. Clunium pale brown; phallosome and hypandrium dark brown; paraprocts and epiproct light brown, with ochre subcuticular spots.

Morphology. Head ( Fig. 100 ) H/MxW: 1.43; compound eyes large, H/d: 4.00; IO/MxW: 0.77; vertex slightly above the level of the upper border of the compound eyes; outer cusp of lacinial tips broad, with 7–8 denticles. Mx4/Mx2: 1.16. Forewings ( Fig. 98 ) L/W: 2.47; pterostigma: lp/wp: 6.01; M six branched, M6 forked as illustrated; areola postica: la/ha: 1.29, tall, wide, distally rounded. Hindwings ( Fig. 99 ) l/w: 2.70; M three branched. Hypandrium ( Fig. 101 ) (see diagnosis), with setal tufts on each side of the median processes, the setae reaching or surpassing the apex of the median posterior processes. Phallosome ( Fig. 103 ) anteriorly V-shaped, side struts wide; external parameres sclerotized, elongate, with rounded apex. Phallosome with five endophallic sclerites. Anterior pair mid sized, broadly triangular. Lateral pair slender, bow shaped, with posterior apices slightly dilated Mesal sclerite large, transverse, M-shaped, side processes long, central process stout, mesal sclerite processes (msp) long, hooked distally, proximally with oblique, tapered and converging processes directed inwards. Paraprocts ( Fig. 102 ) oval, with setal fields as illustrated; sensory fields with 34 trichobothria on basal rosettes. Epiproct ( Fig. 102 ) slightly convex anteriorly, broadly rounded posteriorly, with setae as illustrated and a field of microsetae along posterior border.
