Loneura farallonensis n. sp.

( Figs 31–40 )

Diagnosis. Belonging in Group III ( García Aldrete et al. 2011 b). Related to L. gorgonaensis García Aldrete et al. , from which it differs by having the forewing M3 and M4 distally forked, and in having M5 three branched; also, the hindwing M is three branched, not two branched as in L. gorgonaensis . The posterior projections of the hypandrium are slender and pointed ( Fig. 34 ), not robust and blunt ended as in the latter.

Male. Color (in 80% ethanol). Body pale brown. Head pattern ( Fig. 32 ), with dark brown diagonal band from the inner border of each compound eye to epistomal sulcus, under the level of the antennal fossae. Compound eyes black; ocelli hyaline. Anteclypeus and labrum brown. Genae pale cream from the compound eyes to the subgenal suture. Postgenae creamy. Antennae: scape brown; pedicel and flagella cream. Mx 1–3 cream; Mx 4 brown. Tergal lobes of meso and metathorax creamy, with brown edges. Thoracic pleura with pale brown areas. Legs: fore- coxae and trochanters brown; coxae and trochanters of mid and hind- legs creamy; fore femora cream, with brown proximal spot; mid and hind femora cream, except for a central and subapical brown band; tibiae brown, distally darker; tarsi 1 brown; tarsi 2–3 dark brown. Wings hyaline. Forewing pterostigma hyaline, with proximal and distal brown bands; brown spots at the ends of R2+3, R4+5, M and Cu1; a large brown area between 1A and Cu1. Hindwings with pale brown spots at ends of R4+5, M1-3 and Cu2. Abdomen pale brown. Hypandrium cream, with brown spots. Epiproct and paraprocts cream.

Morphology. As in diagnosis, plus the following: Head ( Fig. 32 ) H/MxW: 1.35; large compound eyes, H/d: 2.5; IO/MxW: 0.71. Vertex slightly below the level of the upper borders of the compound eyes, outer cusp of lacinial tip broad, with 5–6 denticles. Forewings ( Fig. 31 ) L/W: 2.48; pterostigma: lp/wp: 4.75; M five branched, M3 and M4 distally forked, M5 forked proximally, with anterior branch distally forked; areola postica broadly triangular: la/ha: 1.31, high, apically rounded. Hindwings ( Fig. 31 ), l/w: 2.74; M three branched. Hypandrium of one sclerite ( Fig. 34 ), side sclerites fused basally to the central sclerite, this with side blunt processes, and two posterior processes, each with an apical setae, separated by a long, slender space. Phallosome ( Fig. 35 ) V-shaped anteriorly; external parameres slender, curved, rounded distally; three pairs of endophallic sclerites, the mesal and anterior ones stout, independent, the posterior pair V-shaped, with arms slender, each ending in an elongate, earshaped process. Paraprocts ( Fig. 33 ) broad, oval, with field of short setae posteriorly, and long setae mesally; sensory fields with 27–28 trichobothria on basal rosettes. Epiproct ( Fig. 33 ) convex anteriorly, rounded posteriorly, with setae as illustrated.

Female. Color. (in 80% ethanol). Body, head, legs, epiproct, paraprocts and wings as in the males. Subgenital plate cream, with pigmented area brown, V-shaped. Gonapophyses brown, ninth sternum orange.

Morphology. As in diagnosis, plus the following: Head ( Fig. 37 ) H/MxW: 1.38; compound eyes large, H/d: 2.57; IO/MxW: 0.72. Vertex slightly above the level of the upper border of the compound eyes; outer cusp of lacinial tip broad, with 4-6 denticles. Forewings ( Fig. 36 ) L/W: 2.58; pterostigma: lp/wp: 4.62, elongate, wider in the middle; M five branched, M3 and M4 distally forked, M5 forked, each arm distally forked, resulting in four M5 branches; areola postica: la/ha: 1.47, high, broadly triangular, apically rounded. Hindwings ( Fig. 36 ) l/w: 2.76; M three branched. Subgenital plate ( Fig. 39 ) wide, setose, with posterior border rounded, bearing a group of six setae.

Gonapophyses ( Fig. 40 ): v1 elongate, slender and acuminate; v2 +3 with a proximal slender heel, v2 with a row of 6-7 setae; distal process long, sinuous and acuminate, bearing microsetae on surface. Ninth sternum ( Fig. 40 ) distinctly pigmented, subquadrate. Paraprocts ( Fig. 38 ) triangular, with long and short setae posteriorly; sensory fields with 28–30 trichobothria on basal rosettes. Epiproct ( Fig. 38 ) triangular, wide basally, with long setae and microsetae on sides and posteriorly, and a group of three macrosetae mesally.
