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.

Measurements. FW: 1600, HW: 1275, F: 440, T: 630, t 1: 950, t 2: 90, ctt 1: 15, f 1: 260, f 2: 118, f 3: 110, f 4: 92, f 5: 77, f 6: 77, f 7: 57, f 8: 60, f 9: 55, f 10: 47, f 11: 70, Mx4: 122, IO: 370, D: 110, d: 162, IO/d: 2.28, PO: 1.47.

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 ).

Measurements. FW: 1650, HW: 1300, F: 400, T: 620, t 1: 870, t 2: 90, ctt 1: 15, f 1 260, f 2: 110, f 3: 105, f 4: 87, f 5: 70, f 6: 70, f 7: 50, f 8: 55, f 9: 52, f 10: 45, f 11: 70, Mx4: 120, IO: 390, D: 107, d: 167, IO/d: 2.33, PO: 1.56.

Specimens studied. Holotype male, COLOMBIA. Cauca, Guapi, NNP Gorgona, Gorgonilla Beach , 02° 56’ 39.2’’ N: 78° 12’ 45.0’’ W, 4 m, 19.x.2010, MUSENUV slide cod. 25604, R. González . Paratypes: 2 males and 2 females, same data as the holotype MUSENUV slide cod. 25605-25608. Valle del Cauca, Buenaventura, Punta Soldado , 03° 48’ 5’’ N: 77° 0’ 40’’ W, 8 m, 4.iv.2010 , 1 males and 1 females, MUSENUV slide cod. 25609-25610, R. González.

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