Obando, Ranulfo González, García Aldrete, Alfonso N. & Carrejo, Nancy, 2016, New species of Cladiopsocus Roesler (Psocodea: ‘ Psocoptera’: Psocomorpha: Cladiopsocidae) from the Colombian Amazonia, Zootaxa 4127 (1) : -

Cladiopsocus gregoriorum n. sp. Male

( Figs 22–28 )

Diagnosis. Belonging in species group “2”, subgroup 4, in the classification of Eertmoed (1986). In this subgroup it corresponds to species with phallosome with internal parameres vestigial, or not united posteriorly. Unlike C. deliciasensis n. sp., it does not have the paraproctal prong with a tapered basal tooth, and unlike C. prionotus , C. mocoaensis n. sp., C. garciai and C. multimaculatus , the epiproct has two tooth-like short projections distally, along the longitudinal midline ( Fig. 25 ).

Color. Head ( Fig. 24 ) dark brown, anteclypeus and labrum pale brown. Compound eyes dark brown, ocelli hyaline. Antennae pale brown, flagellomeres with clear distal ends; maxillary palps pale brown. Meso- and metanotum brown, thoracic pleura and legs light brown, tibia and tarsi dark brown. Forewing membrane hyaline, with brown spots at wing margin; pterostigma with pale brown spot distally on costal area; wing margin with brown spots between the ends of veins R, M and Cu1 ( Fig. 22 ); veins brown, with brown spots at ends of R, M and Cu1a. Hindwing hyaline with a smoked spot on vein ends, and on wing margin between M and Cu1 ( Fig. 23 ). Abdomen cream, with light brown bands, clunium and hypandrium pale brown; phallosome pale brown; epiproct cream, with two little tubercles dark brown; paraprocts cream, paraproctal prong dark brown, more pigmented distally.

Morphology. As in diagnosis plus the following: head vertex slightly concave, almost on the same level with the top margin of the compound eyes ( Fig. 24 ). D is 60% the length of the head in front view, almost as wide as the interocular distance (1.15); with interommatidial setae. Forewings ( Fig. 22 ), membrane of pterostigma without setae; without spur veins. Hypandrium ( Fig. 27 ) broad, shield-shaped, rounded distally, with medium sized setae and lateral macrosetae. Epiproct trapeziform ( Fig. 25 ), posterior border broadly rounded, three medium sized setae in mesal field, and field of medium sized setae and macrosetae distally. Paraprocts ( Fig. 26 ) with abundant medium sized setae and macrosetae as illustrated; mesal prong stout, strongly sclerotized, acuminate distally; sensory fields with 18 trichobothria on basal rosettes. Phallosome sclerotized, slightly concave anteriorly, wider posteriorly, deeply cleft in the middle; external parameres broad, membranous, bearing pores, endophallic lobes triangular; arms of internal parameres separate, distally pointed, thick, well sclerotized ( Fig. 28 ).
