Elaphopsocus boyacaensis n. sp. Male

( Figs 1–6 )

Diagnosis. Belonging in Species Group III (Román-P. et al. (2015), as modified above. Hypandrium wide, posteriorly concave, with a heavily sclerotized plate on each side. Phallosome with side struts slender, pointed anteriorly; aedeagal arms stout, club shaped; external parameres slender, bow shaped. Differing from E. roesleri in the pattern of the forewing pigmentation, in having the posterior border of the hypandrium concave, with posterolateral corners slightly projected, and in the clearly different phallosomes (compare Fig. 6 with Fig. 45 in Román-P. et al. (2015).

Color (in 80% ethanol). Body light brown. Compound eyes black, ocelli hyaline, with ochre centripetal crescents. Dark brown banding pattern next to compound eyes. Frontal, fronto-genal, and fronto-clypeal sulci dark brown, postclypeus with brown bands as illustrated ( Fig. 1 ). Genae creamy. Coxae, trochanters, femora and tarsi brown, tibiae white. Forewing pattern ( Fig. 3 ), with dark brown spots on proximal half, basal to the discal cell. Light brown bands over a hyaline background distally. Pterostigma with small brown spots. Veins brown ( Fig. 3 ). Hindwings ( 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 the vertex ( Fig. 1 ). Pterostigma acute distally, slightly extended posteriorly towards Rs-M. Cell m wide, almost rectangular, crossvein between areola postica and M long ( Fig. 3 ). Hypandrium broad, with sclerotized plate at each side ( Fig. 5 ), phallosome elongate, with side struts widely separated anteriorly ( Fig. 6 ). Paraprocts elongate, marginally sclerotized, with an elongate anterior “handle”, and a posterior stout prong ( Fig. 2 ), sensory fields with 34 trichobothria in penta-lobed basal rosettes. Epiproct broadly semicircular, slightly convex anteriorly, marginally sclerotized, with a distal setal field ( Fig. 2 ). Clunium densely covered with small papillae, more evident on margins.

Measurements (in microns). FW: 4045, HW: 3862, Mx 4: 215, f1: 662, f2: 471, f3: 421, IO: 520, D: 235, d: 164, IO/d: 3.17, PO: 0.69.
