Calderón-Martínez, Nadia R., González-Obando, Ranulfo & García Aldrete, Alfonso N., 2014, Descriptions and records of Cladiopsocidae and Dolabellopsocidae (Insecta: Psocodea: ‘ Psocoptera’) from Valle del Cauca and National Natural Park Gorgona, Colombia, Zootaxa 3889 (1), pp. 1-30 : 6-9

Cladiopsocus nebulosus n. sp. Female.

( Figs 20–26 )

Diagnosis. Forewing pattern unique ( Fig. 20 ), with brown spots at wing ends and a slender hyaline band from pterostigma, along wing margin, to areola postica, with pigmented spots in cells R1, R2+3, R4+5, and M1-3, with hyaline fenestrae on wing margin of areola postica. Gonapophyses ( Fig. 24 ) long, slender and distally straight. V2 +3 with long, stout, proximal heel, and distal process straight, bearing a field of microsetae; V3 an elongate lobe on V2, bearing a row of long setae. Ninth sternum with elongate, almost oval spermapore ( Fig. 24 ). Subgenital plate ( Fig. 23 ) broad, setose, almost trapeziform, with posterior border almost straight, distinctly pigmented.

Description. Color. Head brown ( Fig. 22 ), postclypeus with V-shaped brown bands with outward curved ends. Compound eyes black, ocelli hyaline. Thorax and legs light brown. Abdomen light brown with brown transverse subcuticular bands, more conspicuous dorsally. Clunium, ovipositor valves and subgenital plate brown; paraprocts and epiproct light brown. Forewing membrane ( Fig. 20 ) smoked, with dark brown band along wing margin, from R2+3 to the base of areola postica; pterostigma with brown spots as illustrated, hindwing with brown spots at vein ends, and four marginal spots between M and CuA ( Fig. 21 ).

Morphology. As in diagnosis, plus the following: forewing with M3 forked and hindwing with Rs-M crossvein. Paraprocts broadly triangular, with setae as illustrated ( Fig. 25 ); sensory fields with 21 trichobothria on basal rosettes. Epiproct ( Fig. 26 ) bell-shaped, with concave antero-lateral corners.

Etymology. The specific name refers to the cloudy forewing membrane, reminiscent of cumulus clouds.

Remarks. This species, as the male is unknown, is not assignable in any of the groups in Eertmoed’s (1986) classification of Cladiopsocus s. str., but it belongs to this subgenus. The spermapore sclerite, as well as the wing pattern is unique in the genus. Also, it is the only species in the genus with a Rs-M crossvein in the hindwing.
