Loneura carijona n. sp. Male

( Figs 34–39 )

Diagnosis. Forewings with a slender submarginal pigmented band from R4+5 to areola postica; pterostigma hyaline, with broad proximal and distal dark brown bands. Hypandrium deeply cleft in the middle, distal third of each posterior process with a broad lobe extended laterally, apices rounded, each with a subapical macroseta on inner margin; proximally a wide lobe extended outwards ( Fig. 37 ). Mesal sclerite processes wide based, narrowing posteriorly, acuminate ( Fig. 39 ).

Color. Body pale brown. Head pattern ( Fig. 36 ), vertex light brown; front with two large brown spots; an ochre transverse band between the inner border of each compound eye to the lower edge of the ocellar triangle and 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 to light brown. Postgenae light brown. Antennae: scape brown; pedicel and flagella pale brown, flagellomeres 1–5 with apices cream. Maxillary palps pale brown. Tergal lobes of meso- and metathorax dark brown, with light brown edges. Thoracic pleura pale brown with dark brown areas. Legs: coxae with small ochre spot basally, fore- coxae and trochanters brown; coxae and trochanters of mid and hind- legs light brown; femora light brown, with two brown spots; tibiae and tarsi brown. Wings hyaline ( Figs 34, 35 ), forewings with brown submarginal band from R4+5 to areola postica, and a dark brown band from the middle of Cu1 to distal end of 1A; dark brown spots on vein ends at wing margin. Hindwings with brown spots on vein ends at wing margin. Abdomen light brown, with subcuticular ochre spots; clunium pale brown. Hypandrium brown. Epiproct and paraprocts light brown.

Morphology. Head ( Fig. 36 ): H/MxW: 1.44; H/d: 3.56; IO/MxW: 0.74. Vertex slightly above the level of the upper border of the compound eyes. Outer cusp of lacinial tips broad, with seven–eight short denticles. Mx4/Mx2: 1.22. Forewings ( Fig. 34 ): L/W: 2.51. Pterostigma: lp/wp: 4.08, areola postica wide, slightly slanted posteriorly, apically rounded: al/ah: 1.68, R4+5 sinuous, M five-branched, M5 forked. Hindwings ( Fig. 35 ): l/w: 2.75; M threebranched. Hypandrium ( Fig. 37 ), setose as illustrated; phallosome V-shaped anteriorly, side struts slender; external parameres laminar, apices rounded, bearing pores ( Fig. 39 ); three pairs of endophallic sclerites, anterior and lateral pair laminar, fused; mesal pair wide basally, mesal sclerite processes distally acuminate. Paraprocts ( Fig. 38 ) robust, almost triangular, with distal setal field and macrosetae as illustrated; sensory fields with 26 trichobothria on basal rosettes. Epiproct ( Fig. 38 ) semioval, with short and long setae, two lateral macrosetae, as illustrated.
