description: Valdasus carpinteroi P. Ferreira & Martins, new species (Figs. 8-D, E)
Diagnosis. Valdasus carpinteroi n.sp. shares greater morphological similarities to Valdasus schoenherri, than other species in the genus. Both species are recognized by their large body (more than 7 mm in length and 3 mm or more in width). Valdasus carpinteroi n.sp. differs from Valdasus schoenherri in the following characteristics: Dorsal region of head black, with two converging white stripes on vertex; lateral area behind eyes black; and antennal segment I dark brown with a whitish base. Clavus uniformly black; cuneus whitish with black apex. Propleura not expanded more than half length of mesepisternum with a straight posterior margin. Ostiolar peritrema white, strongly developed, extending more than half length of mesoepimeron, with a rounded ostiole that opens into a prominent conical structure. Abdomen with middle ventral region light yellowish; lateral regions with large black stripe.
Description. Male (holotype) measurement in Table 2. Body oval, black with pale yellowish spots; dorsal and ventral vestiture with dense, semi-erect setae; length less than 2.5x width. Head vertical, mostly black with pale areas, opaque, rugose with short, erect setae. Vertex concave, with deep median groove, black color, and two converging white stripes. Front flat, clypeus short, pale, with swollen basal region; mandibular plate dark in color and with long, erect whitish setae; maxillary plate yellowish, short, thin, elongated, and smooth. Antennal fossa above mandibular-maxillary suture and close to inner margin of eyes. Labium dark with apex pale, extending to middle of mesosternum. Antennae longer than body length; cylindrical with semi-erect setae length shorter or length near width of respective segments; antennal segment I dark brown with basal region whitish, shorter than width of head; segment II 3 x longer than segment I; relative lengths of antennal segments in ascending order: 1<2<3<4. Pronotum trapeziform, uniformly black, heavily punctate with long, semi-erect setae; width 2.5 x length; posterior margin concave and bisinuous with humeral angles slightly prominent; calli swollen, shagren, delimited by posterior groove but not separated by complete median groove; lateral margin rounded. Mesoscutum dark, punctate, and partially visible. Scutellum punctate, black with white apex, convex, and flattened in anterior part. Hemelytron dull, black, laterally convex, broadly punctate on clavus and most of corium; part of endocorium, cuneus, and embolium, smooth; extreme apex of embolium, small spot on apex of exocorium and cuneus (except apex dark brown), pale yellowish; membrane sooty with rounded spot near apex of cuneus, whitish; veins slightly darker. Ventral surface with xiphus of prosternum punctate and yellowish; propleura black, punctate, and dull; median regions of mesepisternum and metasternum yellowish, with lateral regions black and smooth (except mesepimeron punctate); ostiolar peritreme white, with opening located at apex of raised and conical structure. Legs mostly black, coxae black (other segments absent on the anterior and median legs); hind leg showing coxa black with whitish apex; whitish trochanter; black femur with white ring in apical third; black tibia with two white rings: longer one, located in apical third, and smaller one, near base, slightly swollen, bearing long erect setae; tarsi long and black. Abdomen smooth, hairier laterally with long erect setae; middle ventral region light yellowish; lateral regions with large black stripe; dark brown pygophore. Male genitalia as figure 12-B.
Etymology. Dedicated to Diego Leonardo Carpintero, at the Museo Argentino de Ciencias Naturales “Bernardino Rivadavia” in Buenos Aires, Argentina, in recognition of his contributions to the taxonomy of Hemiptera-Heteroptera, with a focus on the entomofauna of Argentina and the Neotropical Region.
Plant Associations. Unknown.
Distribution. Brazil (Espírito Santo *: Domingos Martins).
Type material. Holotype 1♂, Domingos Martins, Mata Pico do Eldorado, Coord. 200 22’ 17’’ S/ 400 39’ 29’’ W, Col. M. T. Tavares e equipe, 23/XI-3/XII/2004.
Remarks. V. schoenherri is found in the following Brazilian states: Rio de Janeiro (RJ), Santa Catarina (SC), and V. carpinteroi in Espírito Santo (ES) (Wolski et al. 2020). Both species were collected in regions of the Mata Atlantica Biome.
