Elaphopsocus nasa n. sp.

( Figs 1–13 , 53 )

Diagnosis. Hypandrium posteriorly concave in the middle, with slender projections limiting the concavity ( Fig. 6 ). Phallosome fused anteriorly, side struts slender, aedeagal arms stout, curved, acuminate; external parameres dilated posteriorly, each bearing a stout, hook-like projection distally, directed outwards ( Fig. 5 ). Subgenital plate with distal process stout, posteriorly straight, mesally with a pointed apophysis on each side ( Fig. 12 ). Ninth sternum obtusely concave anteriorly ( Fig. 11 ).

Male. Color (in 80% ethanol). Body light brown. Compound eyes black, ocelli hyaline, with ochre centripetal crescents. Dark brown banding pattern next compound eyes. Frontal, fronto-genal, and fronto-clypeal sulci dark brown, postclypeus with brown bands as illustrated ( Fig. 1 ). Genae creamy. Antennae pale brown, scape unpigmented. Maxillary palpomeres dark brown. Coxae, trochanter, femora and tarsi brown, tibiae white. Forewing pattern ( Fig. 3 ), with dark brown spots basally, to the discal cell, and light brown spots over a hyaline background distally. Pterostigma with small brown spots. Veins brown ( Fig. 3 ). Hindwing ( Fig. 4 ), almost hyaline, with cell CuP light brown. Abdomen uniformly light brown; hypandrium more strongly pigmented distally.

Morphology. As in diagnosis, plus the following: vertex slightly concave, with compound eyes not reaching the level of vertex ( Fig. 1 ). Pterostigma rounded distally, slightly extended posteriorly towards Rs-M ( Fig. 3 ). Cell m wide, almost rectangular, crossvein between areola postica and M very short. Hypandrium broad, almost quadrangular, phallosome elongate, slightly fused anteriorly ( Fig. 5 ). Paraprocts elongate, marginally sclerotized, with an elongate anterior “handle”, and a posterior stout prong ( Fig. 2 ). Sensory fields with 32–34 trichobothria in penta-lobed basal rosettes. Epiproct broadly semicircular, slightly convex anteriorly, marginally sclerotized, with setal field on distal third ( Fig. 2 ).

Measurements (in microns). FW: 4275, HW: 3550, IO: 540, D: 170, d: 250, IO/d: 2.16, Mx4: 200, f1: 670, f2: 480, f3: 400, PO: 1.47.

Female. Color (in 80% ethanol). Essentially as in the male, but slightly less pigmented ( Fig. 13 ). Genitalia darker than rest of abdomen, sclerotized. Gonapophyses: v1 uniformly sclerotized; v2 and v3 darker posteriorly. Subgenital plate uniformly dark brown with transverse brown spots.

Morphology. As in diagnosis, plus the following: vertex straight ( Fig. 7 ). Pterostigma, cell m, and crossvein CuA1-M as in the male ( Fig. 9 ). Subgenital plate heavily sclerotized, symmetrical, pigmented area anteriorly concave; setae as illustrated ( Fig. 12 ). Gonapophyses: v1 long, slender, distally acute and basally wide; v2 well developed, quadrangular at base and ending in a distal acuminate projection; v3 small, rounded and bearing a field of setae posteriorly. Ninth sternum symmetrical, spermapore circular and surrounded by a pigmented rim ( Fig. 11 ). Paraprocts simple, faintly sclerotized, quadrangular, with rounded borders, a row of marginal setae on outer margin; sensory fields with 26–28 trichobothria in penta-lobed basal rosettes ( Fig. 8 ). Epiproct distally rounded and basally truncate, with a field of about 28 strong setae on distal half.

Measurements (in microns). FW: 4625, HW: 3350, IO: 530, D: 160, d: 230, IO/d: 2.30, Mx4: 210, f1: 510, f2: 350, f3: 250, PO: 1.43.

Specimens studied. Holotype male. COLOMBIA. Cauca, Puracé (2° 22' N; 76° 23' W); 1875 m. 13.v.2012. MUSENUV slide code 26127. J. Mendivil. Paratype female, same data as the holotype. J. Mendivil. MUSENUV slide code 26128. Three females from the same locality, not dissected, in 75% ethanol.

Etymology. This species is dedicated to the Nasa tribe, that inhabits the type locality.
