Ectopsocus andinus n. sp.

( Figures 1–10 )

Diagnosis. Belonging in species group Fenestratus of Thornton & Wong (1968). Forewing coloration pattern complex ( Fig. 1 ), similar to the Mexican species E. chiapensis García Aldrete , and E. chiapensoides García Aldrete ; differing from the former in having the external parameres curved outward, in having the aedeagal arch pointed, and in having a single, large endophallic sclerite; the posterior side projections of the hypandrium are slender and pointed, and the apical lobes of the subgenital plate bear two distal setae and one setae on the outer margin. It differs from the latter, in having a hyaline area at the fork of Rs-M in the forewing, in having the aedeagal arch pointed, in having a single large endophallic sclerite, in having the posterior side projections of the hypandrium slender and pointed, and in having the apical lobes of the subgenital plate slender, and with one setae on the outer margin of each lobe.

Description. Male. Color. Head dark brown, compound eyes black, ocelli brown with centripetal crescents ochre. Thoracic terga dark brown, coxae with basal halves dark brown, apical halves yellowish. Distal half of forewing brown with three hyaline fenestrae in M 1, M 3, apical and basal region of R 1 and basal R 4+5 cells. Basal half of forewing with transverse band from nodulus to Cu 1, with two hyaline fenestrae in cell Cu. Sc cell light brown, opaque. Pterostigma light brown with dark apex ( Fig. 1 ). Hindwings light cream, with opaque apex in R and Cu cells, subcostal cell light brown. Abdomen light brown with brown, subcuticular dorso-lateral bands.

Morphology. Head as illustrated ( Fig. 3 ). Forewings with thick setae on veins and margins, additional row from Sc to R 4+5; hindwings with glabrous margins ( Fig. 2 ). Phallosome with external parameres stout and curved outward, distally blunt. Aedeagal arch stout, distally pointed. A single, large, irregular endophallic sclerite ( Fig. 4 ), with an anterior projection, and two slender, posterior projections. Hypandrium subrectangular, wider posteriorly, slightly concave, with two side, slender, pointed posterior projections ( Fig. 6 ). Paraprocts rhomboid, without transverse row of setae, sensory fields with nine trichobothria, eight issuing from basal rosettes; marginal spines asymmetric, short and bifid ( Fig. 7 ). Epiproct semicircular, apex not-pigmented ( Fig. 7 ). Clunium vase-shaped, with two antero-lateral tubercular fields; apical comb with 26 stout teeth ( Fig. 5 ).

Female. Color. Same as the male, subgenital plate brown, inner margin of distal lobes not pigmented, outer margin dark brown.

Morphology. Subgenital plate subrectangular, with abundant setae; subapical transverse row of 11–12 long setae; apical lobes triangular, blunt, with three stout setae, two distal and one in outer margin ( Fig. 8 ). Gonapophyses: dorsal valves elongate, curved basally, with a marginal sclerotized band; ventral valves short, boomerang-shaped, external valves stout, with a non-pigmented inner margin and seven setae along outer margin. Ninth sternum membranous, spermapore not visible ( Fig. 10 ). Paraprocts rhomboid, transverse, with a row of four elongate setae; sensory fields with eight trichobothria, seven on basal rosettes; marginal spines short, bifid and asymmetric ( Fig. 9 ). Epiproct bell shaped, apex not pigmented.
