Elaphopsocus gorrones n. sp.

( Figs 14–25 , 52 )

Diagnosis. Forewing pattern ( Figs 16 , 22 ). Hypandrium broad, with postero-lateral corners projected posteriorly ( Fig. 19 ). Phallosome with side struts almost fused anteriorly, each arm slender, elongate, external parameres ending in two pointed projections, one small, directed inwards, the other one larger, directed posteriorly; aedeagal arms slender, distally bent outwards, pointed ( Fig. 18 ). Female subgenital plate with median process wide based, narrowing distally to straight posterior border ( Fig. 25 ); ninth sternum almost rectangular ( Fig. 24 ).

Male. Color (in 75% ethanol). Body reddish brown. Compound eyes black, ocelli hyaline, with ochre centripetal crescents. Fronto-clypeal sulcus white. Genae with brown spots. Antennae brown. Maxillary palpomeres brown. Coxae, trochanters, femora, tibiae and tarsi light brown. Forewing pattern as illustrated ( Fig. 16 ), with small spots over most cells. Veins R2+3, R4+5, M1, M2 and M3 with distal area brown. Pterostigma with a brown spot covering most of the surface. Hindwings hyaline ( Fig. 17 ). Veins light brown. Abdomen uniformly light brown. Genitalia more pigmented than rest of abdomen, sclerotized. Phallosome distally more pigmented; hypandrium with brown spots on surface, irregularly distributed ( Fig. 19 ).

Morphology. As in diagnosis, plus the following: vertex straight. Compound eyes below level of vertex ( Fig. 14 ). Pterostigma rounded and posteriorly projected towards Rs ( Fig. 16 ). Posterior border of hypandrium straight, with a dense field of setae in the middle ( Fig. 19 ). Phallosome ( Fig. 18 ). Paraprocts weakly sclerotized, with prongs stout, bearing a distal, posteriorly directed macroseta; sensory fields with 28–29 trichobothria in basal rosettes. Epiproct distally rounded and basally concave, mostly membranous, with a field of setae mesally ( Fig. 15 ).

Measurements (in microns). FW: 2600, HW: 2075, F: 525, IO: 360, D: 130, d: 180, IO/d: 2, Mx4: 140, f1: 340, f2: 240, f3: 210, PO: 1.38.

Female. Color (in 80% ethanol). Essentially as in the male but with darker coloration. Forewing with large brown spots, hindwing hyaline ( Fig. 22 ). Subgenital plate more pigmented on the sides.

Morphology. As in diagnosis, plus the following: pterostigma as in the male ( Fig. 22 ). Subgenital plate wide basally, setose as illustrated ( Fig. 25 ). Ninth sternum almost quadrate, with spermapore large, surrounded by a pigmented rim. Gonapophyses: v1 long, slender; v2 quadrangular at the basal portion and bearing a distal spinelike projection; v3 oval, bearing few setae posteriorly ( Fig. 24 ). Paraprocts broad, setose; sensory fields with 27–29 trichobothria in basal rosettes ( Fig. 21 ). Epiproct trapeziform, membranous, bearing a row of heavy setae posteriorly and lateral thin setae.

Measurements (in microns). FW: 2475, HW: 1900, F: 550, IO: 440, D: 110, d: 220, IO/d: 2.0, PO: 2.0, Mx4: 120, f1: 330, f2: 220, f3: 200.
