Male ( Figs 50–55 ) Diagnosis. Related to P. canoae n. sp. from which it differs in having the posterior processes of the central sclerite of the hypandrium stouter and distally concave ( Fig. 53 ), in the shape of the side struts of the phallosome, and in the shape and size of the endophallic sclerites (compare Figs 43 and 55 ). Color . Body dark brown, with cream spots. Head brown, with pale and dark brown spots ( Fig. 52 ), with oblique dark brown 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 cream, with small pale brown spots. Postclypeus with converging pale and brown slender bands on each side. Genae dark brown with small pale spots. Postgenae pale brown. Antennae: scape and pedicel brown, flagellomeres pale brown, with apices whitish. Maxillary palps pale brown, Mx4 darker distally. Tergal lobes of meso- and metathorax dark brown to ochre. Thoracic pleura: pro- and mesopleura dark brown, with cream spots, metapleura cream, with small ochre spots. Legs: fore-, middle coxae and trochanters dark brown; hind coxae, trochanters and femora pale cream; fore- and middle femora brown proximally, cream distally; tibiae pale brown, tarsi 1 cream, tarsi 2-3 pale brown. Forewings hyaline, with a marginal brown band from R4+5 to 1A, and small pale spots at the end of veins M and Cu, pterostigma dark brown, veins brown. Hindwings hyaline, veins brown. Abdomen dark brown to ochre, with small, pale cream irregular spots. Hypandrium brown, epiproct and paraprocts cream. Morphology. Head ( Fig. 52 ). H/MxW: 1.48; compound eyes large, H/d: 3.72; IO/MxW: 0.76; vertex slightly below the level of the upper border of the compound eyes; outer cusp of lacinial tips broad, with 7–8 short, rounded denticles. Mx4/Mx2: 1.17. Forewings ( Fig. 50 ) L/W: 2.66; pterostigma: lp/wp: 4.81; M eight-branched, M8 bifurcated distally; areola postica: la/ha: 1.11, tall, narrow, distally rounded. Hindwings ( Fig. 51 ) l/w: 3.00; M fourbranched. Central sclerite of the hypandrium with fields of macrosetae on each side of the longitudinal midline ( Fig. 53 ); apices of the posterior processes of the central sclerite bidentate, concave. Phallosome ( Fig. 55 ) anteriorly V-shaped, side struts as illustrated; five endophallic sclerites; anterior pair broadly elliptic. Lateral sclerites bow shaped, slender proximally, dilated distally, pointed, inner margin with a row of short teeth ( Fig. 55 ). Mesal sclerite wide and concave anteriorly, with sides converging to short, pointed median process. Paraprocts ( Fig. 54 ) oval, with abundant distal setae and microspicules; sensory fields with 28–30 trichobothria on basal rosettes. Epiproct ( Fig. 54 ) convex anteriorly, broadly rounded posteriorly, with short setae and macrosetae, and a field of microspiculae posteriorly. FIGURES 50–55. Ptiloneura hernandezi n. sp. Male. 50.
