Ectopsocus vilhenaioides n. sp.

( Figures 29–39 )

Diagnosis. Belonging in species group Cinctus, of Thornton & Wong (1968). Close to E. vilhenai Badonnel , from which it differs in that the aedeagal arch is stout, rounded posteriorly, lacking the rounded side lobes of the former, also, the phallosome lacks the anterior elongate apophysis; the median sclerite of the clunium is more slender anteriorly, the papillar fields have few papillae, dispersed in a wide area, and the clunial comb has 21–22 short teeth, while in E. vilhenai , the median sclerite of the clunium is much stouter anteriorly, the papillae are densely packed in each field, and the clunial comb has 27 long teeth. The apical lobes of the subgenital plate in E. vilhenai are stout, and the plate has a rounded papillar field next to the gap between the apical lobes ( Badonnel 1955); this papillar field is absent in E. vilhenaioides , and the apical lobes are slender.

Description. Male. Color. Head pale brown. Compound eyes black, ocelli hyaline, with centripetal crescents brown. Thoracic terga dark brown; forewings opaque brown, veins slightly darker. Hindwings opaque, veins dark brown. Legs light brown. Abdomen pale brown with dorso-lateral subcuticular bands dark brown.

Morphology. Head as illustrated ( Fig. 31 ). Forewing veins with short, stout setae, margins with very short, slender setae ( Fig. 29 ); hindwing margin glabrous ( Fig. 30 ). Phallosome elongate, with subtriangular base and a prebasal V-shaped spot. Mesally covered by a membrane slightly sclerotized; with two pairs of slender marginal sclerites in mesal and apical position. External parameres short, basal half stout, apical half acute, bent mesally, with apex slightly curved and sharp. Aedeagal arch cup-shaped with a stout keeled apex. Two endophallic sclerites ( Fig. 32 ): anterior sclerite sinuous and posterior sclerite globose. Hypandrium ovoid, posterior border with three irregular sclerites ( Fig. 35 ), anterior half with a V-shaped, sclerotized subcuticular area, subapical margin with a dark brown transverse band ( Fig. 34 ). Paraprocts without transverse row of setae, sensory fields with nine trichobothria, eight in basal rosettes, marginal spines bifid, elongate and strongly asymmetric ( Fig. 36 ). Epiproct bell-shaped, with apex and base not pigmented ( Fig. 38 ). Clunium cone-shaped, posterior half round, anterior half elongate and subtriangular, with two small papillar areas, apical comb with 21–22 short, stout teeth ( Fig. 33 ).

Female. Color. Same as the male; subgenital plate brown with a longitudinal central area light brown. Apical lobes brown with a subtriangular basal area not pigmented.

Morphology. Subgenital plate subrectangular, distal lobes subtriangular, elongate, slightly inclined; with 4 setae, gap between lobes high. Subapical transverse row with 11 setae ( Fig. 37 ). Gonapophyses: ventral valves short and curved, dorsal valves membranous, with a small, sclerotized marginal band, external valves with rounded apex and seven stout setae. Ninth sternum membranous, with a sclerotized central plate and circular spermapore ( Fig. 39 ). Paraprocts ovoid; transverse row of 5–6 long setae, sensory fields with nine trichobothria, eight in basal rosettes; marginal spines bifid, asymmetric, short and robust ( Fig. 38 ). Epiproct bell-shaped, posterior border not pigmented ( Fig. 38 ).
