Loneura koreguaje n. sp. Male

( Figs 52–57 )

Diagnosis. It differs from the other species in the group by having the mesal processes of the hypandrium straight, triangular, directed outwards, and the posterior processes short, distally rounded, directed postero-laterally ( Fig. 55 ).

Color. Body brown. Head pattern ( Fig. 54 ), vertex light brown; front with brown spots; an ochre transverse band between the inner border of each compound eye below the lower edge of the ocellar triangle to the epistomal sulcus; a cream diagonal band from the inner border of each compound eye to the epistomal sulcus, at the level of the antennal fossae. Compound eyes black, ocelli hyaline with ochre centripetal crescents. Labrum, anteclypeus, postclypeus and mandibles dark brown. Genae ochre. Postgenae light brown. Antennae: scape brown; pedicel and flagella pale brown, flagellomeres 1–5 with apices cream. Maxillary palps dark brown. Tergal lobes of meso- and metathorax dark brown, with light brown edges. Thoracic pleura light brown, with large dark ochre areas. Legs: coxae with small ochre spot basally, fore- coxae, trochanters and femora brown; coxae, trochanters and femora of mid- and hindlegs pale brown; femora with two brown spots; tibiae and tarsi brown. Wings hyaline ( Figs 52–53 ). Forewing pterostigma dark brown, with a hyaline central area; a submarginal, irregular brown band from R4+5 to areola postica, and a brown band from the middle of Cu1 to the distal end of 1A; a brown spot on vein ends at wing margin. Hindwings with brown spots on vein ends at wing margin. Abdomen brown, with subcuticular ochre bands on tergum; sternum with ochre subcuticular spots. Clunium brown. Hypandrium dark brown. Epiproct and paraprocts light brown.

Morphology. Head ( Fig. 54 ): H/MxW: 1.45; H/d: 3.80; IO/MxW: 0.75. Vertex slightly above the level of the upper border of the compound eyes. Outer cusp of lacinial tips broad, with five–six short denticles. Mx4/Mx2: 1.13. Forewings ( Fig. 52 ): L/W: 2.62. Pterostigma: lp/wp: 4.68, areola postica tall, apically rounded: la/ha: 1.35, R4+5 sinuous, M five-branched, M5 forked. Hindwings ( Fig. 53 ): l/w: 2.94; M three-branched. Hypandrium ( Fig. 55 ), deeply cleft posteriorly in the middle; each posterior projection stout, directed outwards. Phallosome V-shaped anteriorly, side struts slender; external parameres wide, apex rounded, bearing pores and sclerotized short teeth ( Fig. 57 ); two pairs of endophallic sclerites, anterior and lateral pairs fused, boomerang-shaped; mesal pair wide basally, mesal sclerite processes wide proximally, tapered distally. Paraprocts ( Fig. 56 ) robust, almost oval, with distal setal field, spicules and macrosetae as illustrated; sensory fields with 25–26 trichobothria on basal rosettes. Epiproct ( Fig. 56 ) semioval, with short and long setae and a posterior field of microspicules.
