Román-P, Cristian, Obando, Ranulfo González & García Aldrete, Alfonso N., 2015, The genus Elaphopsocus Roesler (Psocodea:`Psocoptera´: Psocidae) with six new species from Brazil and Colombia, Zootaxa 3957 (2), pp. 151-168 : 164-167

Elaphopsocus roesleri n. sp.

( Figs. 43–49 , 54 )

Diagnosis. Hypandrium with postero-lateral corners extended posteriorly to form long, slender, acuminate projections; posterior border convex, bearing a dense field of setae ( Fig. 49 ). Phallosome with side struts stout, independent, aedagal arms stout, distally pointed; external parameres long, stout, distally with a pointed projection directed outwards; ( Fig. 45 ).

Color (in 80% ethanol). Body brown. A creamy area between third ocellus and epistomal sulcus, postclypeus with dark brown bands converging medially. Epiproct centrally membranous ( Fig. 44 ), paraprocts dark brown.

Forewing pattern ( Fig. 47 ). If the forewing is illuminated from below, the pterostigma shows little black spots ( Fig. 54 A); if the forewing is illuminated from above, the pterostigma appears white ( Fig. 54 B). Hindwings hyaline ( Fig. 46 ). Veins brown.

Morphology. As in diagnosis, plus the following: Compound eyes not reaching the level of the vertex ( Fig. 43 ). Pterostigma much wider posteriorly ( Fig. 47 ). Paraprocts weakly sclerotized, bearing posteriorly a pointed prong; sensory fields with 25–26 trichobothria in basal rosettes. Epiproct trapeziform, with setae on sides and posterior border ( Fig. 44 ).

Measurements (in microns). FW: 3725, HW: 2875, IO: 1.07, D: 260, d: 280, IO/d: 1.64, Mx4: 70, f1: 660, f2: 440, f3: 360, f4: 290, PO: 1.07.

Specimen studied. Holotype male. COLOMBIA. Huila. Merenberg Nature Reserve (02° 13' 06.6'' N: 76° 07' 01.1'' W), 2352 m, 21.i.2015. MUSENUV slide code 26134, beating branches, R. González.

Etymology. This species is dedicated to the late German entomologist Rudolf Roesler, who, in 1940, described the genus Elaphopsocus , on the basis of two male specimens, from Nova Teutonia, Santa Catarina, Brazil.
