Loneura altaquerensis n. sp. Male

( Figs 29–33 )

Diagnosis. Mesal lateral processes of the central sclerite of the hypandrium proximally broad, with margins converging to round apices ( Fig. 32 ). It differs from the other species in the group by the shape of the hypandrium and by the shape of the phallosome endophallic sclerites ( Fig. 33 ).

Color. Body light brown. Head light brown ( Fig. 31 ), with an ochre band from each compound eye to the epistomal sulcus and ocellar triangle; genae dark brown; postgenae light brown. Compound eyes black, ocelli hyaline, with ochre centripetal crescents. Postclypeus light brown, with posterior ochre area V–shaped; anteclypeus and labrum light brown. Maxillary palps light brown, Mx4 dark brown. Antennae light brown, flagellomeres 1–3 with apices cream. Thorax pale brown, pronotum and tergal lobes of meso- and metathorax pale brown. Legs light brown, tarsi 2–3 dark brown, fore- and middle coxae with ochre spot basally; femora with distal brown spots. Wings hyaline ( Figs 131, 132 ). Forewings ( Fig. 29 ) pterostigma with proximal and distal brown bands; veins light brown, with dark brown areolae in setal insertions, a dark brown spot on vein ends at wing margin. Hindwings ( Fig. 30 ) with a brown spot at vein ends. Abdomen light brown, clunium pale brown. Hypandrium light brown; epiproct and paraprocts cream. Phallosome brown, with endophallic sclerites dark brown.

Morphology. Head ( Fig. 31 ): H/MxW: 1.48; H/d: 3.85; IO/MxW: 0.75. Vertex at the same level as the upper border of the compound eyes. Outer cusp of lacinial tips broad, with four short and widely rounded denticles. Mx4/ Mx2: 1.12. Forewings ( Fig. 29 ): L/W: 2.58. Pterostigma: lp/wp: 4.43, areola postica tall, apically rounded: al/ah: 1.36, R4+5 sinuous, M five-branched, M5 forked. Hindwings ( Fig. 30 ): l/w: 2.88; M two-branched. Hypandrium ( Fig. 32 ): deeply cleft in the middle, posterior projections stout, blunt ended, each with a subapical macroseta on inner margin, mesal lateral processes broad, triangular. Phallosome V-shaped anteriorly, side struts slender; external parameres laminar, wide, apex rounded, bearing pores and sclerotized short teeth on the outer margins ( Fig. 33 ); four pairs of endophallic sclerites, anterior pair elongate, lateral sclerites wide, with concave margins, tapered, directed posteriorly; mesal pair wide basally, mesal sclerite processes distally curved outward, distally fused to posterior sclerite, tapered and apically curved outward. Paraprocts oval, with distal setal fields; sensory fields with 22–24 trichobothria on basal rosettes. Epiproct semioval, with short and long setae.

Measurements. FW: 3400, HW: 2375, F: 775, T: 1382, t1: 625, t2: 80, t3: 120, ctt1: 21, f1: 612, f2: 525, f3: 475, Mx4: 190, IO: 390, D: 296, d: 200, IO/d: 1.95, PO: 0.68.
