Ptiloneura tunkywasi Carrejo, González & García Aldrete.

( Figs 104–115 )

Diagnosis. Similar to P. jinotegaensis (García Aldrete) , and P. mirandaensis (García Aldrete) , differing from them in the shape of the central sclerite of the hypandrium and posterior side sclerites ( Fig. 109 ) and in the shape of the endophallic sclerites ( Fig. 108 ).

Male. Color. Body brown, with light brown spots. Head light brown ( Fig. 106 ) with two narrow and curved ochre bands from the inner border of each compound eye to the epistomal sulcus, enclosing the antennal fossae. Compound eyes dark brown, ocelli hyaline, with ochre centripetal crescents. Vertex light brown, with brown spots. Postclypeus with brown V-shaped area, light brown mesally. Anteclypeus and labrum light brown. Genae light brown to cream, with brown spots, postgenae cream, with white area. Antennae: scape and pedicel light brown, flagellomeres pale brown, with apices cream. Maxillary palps light brown, Mx4 brown distally. Pronotum and mesonotum cream with brown spots; tergal lobes of metathorax brown. Thoracic pleura light brown two cream, with pale ochre spots. Legs light brown, coxae with two brown spots, trochanters and femora with brown to greyish pigmentation, tibiae and tarsi brown. Wings hyaline, forewing pterostigma dark brown, with a large hyaline area in the middle; a pale brown marginal band from R4+5 to distal half of 1A, with hyaline fenestrae on each side of vein ends ( Fig. 104 ). Hindwings veins brown.Abdomen light brown. Clunium and sclerites of hypandrium brown to dark brown; phallosome dark brown. Epiproct and paraprocts light brown.

Head ( Fig. 106 ) H/MxW: 0.85; large compound eyes, H/d: 2.99; IO/MxW: 0.42; vertex slightly below the level of the upper border of the compound eyes; outer cusp of lacinial tips broad, with seven denticles. Mx4/Mx2: 1.30. Forewings ( Fig. 104 ) L/W: 2.72; pterostigma: lp/wp: 5.41, elongate, wider in the middle; M fivesix-branched, some with M6 forked; areola postica: la/ha: 1.83, tall, wide, apically rounded. Hindwings ( Fig. 105 ) l/w: 2.98; M four-branched. Hypandrium of five sclerites ( Fig. 109 ), central sclerite wider than long, with a deep medial sulcus and an elongate, basally wide and distally acuminate median projection, with dense tufts of macrosetae on each side; posterior side sclerites triangular, with narrow and elongate basal process, directed outwards, posterior process almost straight, acuminate distally and curved outwards. Phallosome ( Fig. 108 ) V-shaped anteriorly, side struts wide basally; external parameres elongate, with rounded apices, bearing small pores. Five endophallic sclerites.Anterior pair mid sized, broadly rounded, with a concavity in the inner border. Lateral endophallic sclerites (les) long, curved, with widened distal area, internal margins almost straight, bearing a row of teeth. Mesal sclerite transverse, with two laminar, wide processes on the anterior margin, posteriorly with triangular process and rounded apex mesally, with short and truncated lateral process on each side; mesal sclerite processes (msp) elongate, basally wide, curved inwards distally, with two short and spaced teeth directed outwards. Paraprocts ( Fig. 107 ) oval, setae and macrosetae as illustrated; sensory fields with 32 trichobothria on basal rosettes. Epiproct ( Fig. 107 ) wide, anteriorly convex, posteriorly rounded, with microspicules on basal field and apically, macrosetae and setae as illustrated.

Female. Color. Body, head, legs, wings, epiproct and paraprocts as in the males. Pigmented area of subgenital plate V-shaped, less pigmented posteriorly and mesally on the sides ( Fig.115 ). Gonapophyses: v1 hyaline with long brown longitudinal band, v2+3 brown, with oval hyaline area in the middle. IX sternum yellowish to cream.
