description: Valdasus henryi n. sp.
(Figures 5, 15, 30–32, 48–51, 61–64, 67, 68)
Examined specimens: Holotype (♂): Ecuador: Napo: Tiputini Biodiversity Station, 216 m, 00º37′55″S; 76º08′39″W, 22 Oct. 1998, Erwin, T. L. et al. leg.; Insecticidal fogging of mostly bare green leaves, some with covering of lichenous or bryophytic plants, Lot 1976, Transect T-8 (USNM); 1♀: the same data as for holotype (USNM).
Diagnosis: Recognized by the following set of features: antennal segment I shorter than vertex width, with three dark brown annulations; clypeus strongly convex basally (Fig. 31); mesepimeron punctate (Fig. 31); scutellum convex medially (Figs 30, 31); mesofemur and mesotibia with setae longer than leg segment diameter (Fig. 31); left paramere with apical process furnished with distinct process dorsobasally (Fig. 49); endosoma furnished with four sclerites (Fig. 48); sclerotized ring unpaired, encircling bursa copulatrix, its basal inner portions connected by broad sclerite (s) (Fig. 61, 63, 64); sclerotized areas of ventral wall of bursa copulatrix well-developed (Fig. 62).

Male. COLORATION. Head. Fuscous tinged with yellow; first antennal segment yellow with three dark brown annulations situated basally, medially, and apically; second segment dark yellow on basal half and dark brown on apical half, apex with narrow, yellow annulation; third and fourth segments missing; labium dark brown (Fig. 5, 15). Thorax. Pronotum, mesoscutum and scutellum. Uniformly black; scutellum with small, yellow patch apically. Thoracic pleura. Black; evaporative area of metepisternum dark brown, ventral portion dark yellow. Hemelytron. Black; outer angle of exocorium and basal part of cuneus yellow; membrane fuscous, veins dark brown. Legs. Procoxa dark castaneus, narrowly yellow apically; meso- and metacoxae yellow; trochanters yellow; pro- and mesofemora dark castaneus; profemur with broad, yellow annulation subapically; mesofemur with two broad annulations: one situated basally and other subapically; pro- and mesotibiae dark castaneus with two broad annulations: on situated basally and other subapically (Fig. 5). Abdomen. Dark brown dorsally, laterally and ventrally. TEXTURE AND VESTITURE. Head. Covered with dense, long, erect setae; antennal segment I shiny, with several stiff setae; segment II shiny, covered with fine, sparse, semi recumbent setae, becoming longer on apical half (Figs 15, 31). Thorax. Pronotum. Collar covered several fine, erect setae. Mesoscutum and scutellum. Mesoscutum impunctate medially, punctate laterally. Thoracic pleura. Covered with long, erect setae; proepisternum impunctate; proepimeron deeply and densely punctate; mesepisternum rugose, mesepimeron rugopunctate; metepisternum rugose. Hemelytron. Covered with long, erect setae; margin of exocorium with well-developed spine near base. Legs. All coxae, protibia and pro- and mesofemora covered with long, erect and semi recumbent setae, not longer than diameter of these segments; mesotibiae covered with long, erect and semi recumbent setae, longer than diameter of leg segments, shorter on apical part (Figs 5, 30, 31). STRUCTURE. Head. Clypeus strongly convex near base; antennal segment I broadly widened medially, shorter than width of vertex; segment II weakly curved, thin, much thinner than first segment; labium reaching mesocoxae (Figs 15, 30, 31). Thorax. Scutellum. Medial part strongly convex. Thoracic pleura. Covered with long, erect setae; proepisternum impunctate; proepimeron deeply and densely punctate; mesepisternum rugose, mesepimeron rugopunctate; metepisternum rugose, peritreme oval, moderately raised evaporative areas. Hemelytron. Margin of exocorium with well-developed spine near base (Figs 5, 30, 31). Genitalia. Endosoma furnished with four sclerites, sclerotized, distal part of ductus seminis inside endosoma weakly developed, secondary gonopore rather narrow, with distinct microsculpture (Fig. 48); left paramere C-shaped, apical process furnished with distinct process dorsobasally (Figs 49, 50); right paramere sickle-shaped, apical process relatively long (Figs 51).
Female. Similar in coloration, structure, texture, and vestiture. Body slightly bigger and more oval. Genitalia. Bursa copulatrix ovoid; sclerotized ring unpaired, encircling bursa copulatrix, its basal inner portions connected by broad sclerite (s); lateral oviduct relatively long; sclerotized areas of ventral wall of bursa copulatrix well-developed (sv) (Figs 61–64).
Etymology. It gives us a great pleasure to dedicate this new species to Dr. Thomas J. Henry for his many outstanding contributions to the study of the Heteroptera.
Biology. Collected using insecticidal fogging of mostly bare green leaves, some with covering of lichenous or bryophytic plants.
Distribution. Ecuador (Napo).
Discussion. Valdasus henryi n. sp. can be separated from the other species of the genus by the following combination of characters: Size relatively reduced (total length about 5 mm), pronotum and embolium evenly coloured, dark, similar in color to clavus and corium, endosoma with four sclerites and the shape of the female genitalia
