Román-P, Cristian, García Aldrete, Alfonso N. & Obando, Ranulfo González, 2014, Elaphopsocoides, a new genus of Psocidae (Psocodea:´Psocoptera´) from Valle del Cauca, Colombia, Zootaxa 3873 (1), pp. 93-100 : 94-97

Elaphopsocoides n. gen.

Diagnosis. Belonging in subfamily Amphigerontiinae sensu Lienhard & Smithers (2002) and Yoshizawa et al. (2011). Differing from Elaphopsocus mainly in having the hypandrium with distal processes and the side struts of the phallosome independent. Female subgenital plate broad, with a wide posterior projection, with posterior border obtusely concave. Gonapophyses: v1 wide based, slender, elongate, distally acuminate, v2 broad, with slender distal process, v3 oval, with a row of setae on posterior border,, with posterior lobe.

Type species. Elaphopsocoides colombiensis n. sp.

Etymology. The generic name refers to the similarity of this genus with Elaphopsocus Roesler.

Elaphopsocoides lahonduraensis n. sp. ( Figs 14–21 )

Diagnosis. Differing from E. colombiensis in having the median process of the hypandrium wider, coarsely serrate on the sides, and with postero–lateral corners projected, pointed; in having two long projections on each side, both acuminate, the outer one much stouter, and in having the phallosome broadly V–shaped.

Veins brown. Abdomen yellowish dorsally, lateral and ventral surfaces with yellow spots on brown background. Terminalia dark brown, heavily sclerotized.

Morphology. Head vertex slightly concave ( Fig. 15 ). Hypandrium symmetrical ( Fig. 16 ), with two acuminate projections on each postero–lateral corner, the outer one stouter; a mid, setose, stout posterior process, with sides coarsely serrate. Anterior hypandrium projections slender; posterior projections thick. Setae scattered in central zone of the hypandrium. Forewing venation ( Fig. 17 ). Paraprocts elongate, outer border with a pigmented band and a distal spine–like projection; setae as illustrated, sensory fields with 36 trichobotria in basal rosettes. Epiproct almost trapeziform, slightly rounded posteriorly and concave near clunium; setae as illustrated ( Fig. 21 ). Phallosome ( Fig. 20 ) elongate, V–shaped, each side strut distally with an inwardly directed, wide based, pointed process. External parameres distally dilated, pointing outwards, bearing a field of short spines. Aedeagus long, slender, slightly curved proximally, each arm terminating in a field of short spines.
