Manchola, Oscar Fernando Saenz, Obando, Ranulfo González & García Aldrete, Alfonso N., 2014, Ectopsocidae (Psocodea: ‘ Psocoptera’) from Valle del Cauca and NNP Gorgona, Colombia, Zootaxa 3786 (5), pp. 523-540 : 528-532

Ectopsocus valvilobatus n. sp.

( Figures 18–28)

Diagnosis. E. valvilobatus is similar in shape, morphology of clunium and wings to E. titschacki , but it has an aedeagal arch stout, apically rounded, V-shaped, while in the latter the internal parameres are fused in a wide apical structure with two subtriangular lateral projections. In E. valvilobatus the eight abdominal tergite has two papillar fields in the middle of the posterior margin ( Fig. 22), absent in E. titschacki . In addition, the females of E. valvilobatus have lobed external valves, quite different from those in E. titschacki .

Description. Male. Color. Head creamy, compound eyes black, ocelli hyaline. Thoracic terga pale brown. Legs pale yellow. Fore- and hind- wings creamy, with veins and margins light brown, abdomen pale yellow with dorsal subcuticular bands pale brown

Morphology. Head as illustrated ( Fig. 20). Short setae on forewings veins and margins ( Fig. 18). Hindwing margin glabrous ( Fig. 19). Hypandrium broad, with setae as illustrated, longer than maximum width, posterior border slightly lobed ( Fig. 24). Six endophallic sclerites present ( Fig. 21): three anterior, two crescent shaped and one sinuous; three posterior, one stout, “handle” shaped, one sinuous, with a pair of sharp projections and one arcuate, inverted. Paraprocts broadly elliptic, without transverse row of setae, sensory fields with nine trichobothria, eight in basal rosettes; marginal spines asymmetric, short and bifid ( Fig. 25). Epiproct bell-shaped, with setae as illustrated ( Fig. 25). Clunium ( Fig. 23), apical comb with 26–29 teeth apically blunt.

Female. Color. Same as the male; subgenital plate with apical lobes light brown.

Morphology. Subgenital plate broad, with setae as illustrated ( Fig. 26); subapical transverse row with six stout setae ( Fig. 26). Gonapophyses: ventral and dorsal valves membranous, with a small, sclerotized marginal band, external valve with lobed apex and six setae. Ninth sternum membranous, with a well sclerotized comma-shaped spermapore ( Fig. 28). Paraprocts ovoid, with a transverse row of 4–5 long setae; marginal spines bifid, symmetric and short; sensory fields with nine trichobothria, eight in basal rosettes ( Fig. 27). Epiproct bell-shaped, setae as illustrated ( Fig. 27).

Etymology. The specific name refers to the strongly lobed external valves of the female.
