Description. The overall somatic morphology is as describedfor I.scutellata,exceptforthefollowingfeatures. Body densely punctured, brownish.Head.Labrum inserted anteriorly to half the distance between the anterior margin of the eyes and the apex of mandibular plates. Antennae: segment I and dorsal surface of segments II and III dark yellowish with minute brown blotches, ventral surface of segments II and III light-brown, segments IV and V dark brown; segments ratio: I>II<III<IV<V.

Thorax. Hemelytra: corium as long as scutellum; conspicuous spot at apex of the radial vein blotch. Pro-, meso- and metapleura dark yellowish.. Setae on posterodorsal margin of protibiae as long as the others.

Abdomen. Dark spots at the lateral of urosternites irregularly shaped narrow; male urosternite VII unarmed.

Male. Apical margin of membrane of hemelytra convex; median portion of posterior margin of urosternite VII subrectilinear; urosternite VII not reaching anteriorly the imaginary line connecting the spiracles of urosternite V.

Genitalia. Pygophore with dorsal rim concave (Fig. 46C, dr); ventral rim sinuous with wide and shallow median depression (Fig. 46D, vr). Posterolateral angles 0.5 times shorter than the rest of the pygophore, perpendicular to the frontal plane and subparallel (Fig. 46C–E, pla). Setae in a narrow band on the ventral rim, on the median depression of ventral rim and outer surface of posterolateral angles; longer and denser on the laterals of ventral rim and apex of posterolateral angles. Segment X wider than long, surpassing the apex of posterolateral angles and dorsally covering the parameres; cordiform; apical margin sclerotized and emarginated; lateral margins sclerotized, densely covered by long setae; mid-longitudinal region membranous covered by setae, short and sparse on basal portion and longer and denser on distal portion Figs. 46C–E, X; 46L–M). Parameres claviform, flat, oblique to the frontal plane; outer margin sinuous, distal portion strongly convex; inner margin sinuous; setae covering the distal portion of ventral surface of the head (Figs. 46D, pa; 46F–I). Cup-like sclerites externally visible, apices rounded and subparallel (Fig. 46D, cls). Phallus: vesica dorsally flat, ventrally expanded; distal portion of vesica sinuous, ventrally directed; secondary gonopore beveled (Fig. 46J–K).

Female. Membrane of hemelytra not reaching the posterior margin of mediotergite VIII, posterior margin convex; median portion of posterior margin of mediotergite VIII concave; median portion of posterior margin of urosternite VII subrectilinear; projections of urosternite VII thicke and slightly oblique to the surface of urosternite VII (Fig. 47C, mpr). Genitalia. Valvifers VIII wider than long; posterior margin sinuous, median portion subrectilinear, lateral portion forming a subtriangular projection; sutural margins subrectilinear and folded dorsally; surface longitudinally convex, dark yellowish with brown punctures, setae on the distal portion of sutural margins and on median portion of posterior margin; longitudinal grooves narrow and shallow on basal portion (Figs. 5M; 47C, vf8). Valvifers IX partially covered by the valvifers VIII, lateral margin subrectilinear, setae on mid-basal portion of ventral surface (Fig. 47C–D, vf9). Laterotergites IX not reaching the posterior margin of mediotergite VIII; lateral margin convex; setae on mid-basal portion of lateral margin and ventral surface (Fig. 47C–D, la9). Thickening of vaginal intima slightly wider than long; proximal margin subrectilinear; distal margin convex, emarginated, and sclerotized; lateral margins convex; surface membranous on the proximal margin and on mid-longitudinal subtriangular area (Fig. 47D, vi). Vesicular area anterior to the collar 1/5 of the posterior portion; median duct anterior and posterior to the collar with proximal widening (Fig. 47D, md, mdp); inner duct coiled in the proximal widening (Fig. 47D, id). Distal ductus receptaculi of same caliber as the proximal one (Fig. 47D, drd, drp). Pars intermedialis broader distally (Fig. 47D, pi); proximal annular crest directed to the ductus receptaculi; distal annular crest perpendicular to the pars intermedialis and almost twice the diameter of the proximal one (Fig. 47D, dac, pac). Capsula seminalis globose; laterobasal projection sinuous, long; lateral projection minute (Fig. 47D, cs, pr).

Measurements: Table 21.

Distribution. Brazil (Minas Gerais) (Fig. 8).

Comments. The males of Ischnopelta vellozia sp. n. have a cordiform segment X (Fig. 46L–M), as in I. anangulata sp.n. (Fig. 13C, X), I. cordiformis sp. n. (Fig. 20L–M), and I. wigodzinskyi sp. n. (Fig. 48L– M). However, in I. anangulata the posterlateral angles of the pygophore are not developed (Fig. 13C–D), in I. wigodzinskyi they are 0.3 times the length of the pygophore (Fig.48C, pla), whereas about 0.5 times in I. vellozia (Fig. 46C–D, pla) and I. cordiformis (Fig. 20C–D, pla). Precisely defining the identity of males on the last two species requires a more detailed analysis of the genital structures. For the females, the triangular projection on the lateral angle of valvifers VIII is larger in I. vellozia (Figs. 5M; 47C, vf8) than in I. wigodzinskyi (Fig. 5N, 49C, vf8).
