Elaphopsocus roeslerioides n. sp. Male

( Figs 13–18 )

Diagnosis. Belonging in Species Group III (Román-P. et al. 2015) as modified above. Hypandrium concave, with a pair of heavily sclerotized postero-lateral acuminate projections of mid length. Phallosome with side struts stout, independent; aedeagal arms stout, distally pointed; external parameres long, stout, distally with a pointed projection directed outwards. Related to E. roesleri , from which it differs in having the postero-lateral projections of the hypandrium approximately half as long, and in having the aedeagal arms and external parameres stouter (compare Fig. 15 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. Frontal, fronto-genal, and fronto-clypeal sulci dark brown, postclypeus with dark brown bands as illustrated ( Fig. 13 ). Genae creamy with dark colored margins. Antennae pale brown, scape unpigmented. Maxillary palpomeres dark brown. Coxae, trochanters, femora and tarsi brown, tibiae white. Forewing pattern ( Fig. 16 ), with dark brown proximally, basal to the discal cell. Light brown spots over a hyaline background distally. Pterostigma with small brown spots. Veins brown ( Fig. 16 ). Hindwing ( Fig. 17 ), almost hyaline, with cell cup slightly darker. Abdomen uniformly light brown; hypandrium strongly pigmented posteriorly.

Morphology. As in diagnosis, plus the following: vertex straight, with compound eyes not reaching the level of the vertex ( Fig. 13 ). Pterostigma acute distally, slightly extended posteriorly towards Rs-M. Cell m wide, almost rectangular, crossvein between areola postica and M long ( Fig. 6 ). Hypandrium broad ( Fig. 18 ); phallosome elongate, with side struts separated anteriorly ( Fig. 15 ). Paraprocts elongate, marginally sclerotized, with an elongate anterior “handle”, and a posterior stout prong ( Fig. 14 ). Sensory fields with 24 trichobothria in pentalobed basal rosettes. Epiproct trapezoidal, marginally sclerotized, with a marginal field of setae ( Fig. 14 ).

Measurements (in microns). FW: 4325, HW: 3861, IO: 532, D: 262, d: 154, IO/d: 3.45, Mx 4: 200, f1: 670, f2: 480, f3: 400, PO: 0.63.

Specimen studied. Holotype male. COLOMBIA. Huila. Meremberg Nature Reserve , 02° 13' 06.6'' N : 76° 07' 01.1'' W, 2352 m, 11.ii.2016. MUSENUV slide code 26147, beating branches, R. González.

Etymology. The specific name refers to the similarity of this species with E. roesleri Román-P., González & García Aldrete.
