038287872C3FFF93FF77FC76FA37027C.taxon	discussion	Comments. The characteristics proposed by Rolston (1990) for the identification of Ischnopelta in his key and diagnoses for the genera of broadheaded discocephalines are still valid. Besides the characteristics listed by Rolston (1990), the long scutellum with the frenal lobe in average 0.65 times smaller than the post-frenal in Ischnopelta, differs from the subtriangular scutellum with subequal frenal and post-frenal lobes in Discocephala (Becker & Grazia 1992), as well as in Nigrisagitta Rosso & Campos, 2017 (Rosso & Campos 2017 a, b). It is noteworthy that, within the broadheaded Discocephalini, the dilated distal 2 / 3 of protibia, the longitudinal groove on antennal segments II and III, and the collar on the proximal portion of the vesicular area in the spermatheca, were only observed in Ischnopelta. Regarding the differentiation between species of Ischnopelta, only the genital characteristics allow an unambiguous identification.	en	Rosso, Pedro, Campos, Luiz Alexandre (2021): Revision of Ischnopelta Stål, 1868 with the description of twenty new species (Hemiptera: Pentatomidae: Discocephalinae).

The dorsal rim of the pygophore is sinuous in I. alalonga (Fig. 11 C, dr) and slightly concave in I. crassula (Fig. 22 C, dr), the parameres with more developed apical process, and the area with differentiated texture in the inner surface is longer and narrow in I. alalonga (Figs. 11 F – I; 22 F – I); the proximal portion of vesica is laterally biconvex in I. alalonga (Fig. 11 K, vs), while in I. crassula it is wider at the base and gradually narrows up to the curvature (Fig. 22 K, vs). The female hemelytral membrane surpasses the posterior margin of mediotergite VIII in I. alalonga (Fig. 12 A – B), but not in I. crassula (Fig. 23 A – B). The thickening of the vaginal intima forms a median and elliptical membranous cone, and the dorsal longitudinal ridges are sinuous and divergent distally reaching the margins in I. alalonga (Fig. 12 D, iv), while in I. crassula the cone is subtriangular, and the ridges are sinuous and not reaching the margins (Fig. 23 D, iv).	en	Rosso, Pedro, Campos, Luiz Alexandre (2021): Revision of Ischnopelta Stål, 1868 with the description of twenty new species (Hemiptera: Pentatomidae: Discocephalinae).

038287872C1DFFB8FF77FF36FAEB035E.taxon	discussion	Comments. Although the posterior margin of valvifers VIII of Ischnopelta cordiformis sp. n. is similar to I. montana sp. n., in I. cordiformis the sutural portion is more angular and the median portion is subrectilinear (Figs. 5 Q; 21 C, vf 8), while in I. montana the sutural portion is strongly convex, and the lateral portion is concave (Figs. 5 R; 37 C, vf 8). Besides that, the lateral abdominal margins in I. montana are delineate by an unpunctured narrow band where two subtriangular darkbrown spots are observed on the laterals of the urosternites (Fig, 37 B), while in I. cordiformis the punctures extend close to the abdominal margins, leaving only small unpunctured areas, and the lateral spots are narrower and irregular, sometimes elongated (Fig, 21 B). Lastly, females of I. cordiformis do not present sclerotized rims on the lateral 1 / 3 of posterior margin of urosternite VII. The undeveloped posterolateral angles, and the cordiform segment X with broad membranous area in I. cordiformis (Figs. 20 C – D, pla; 20 L – M) allows to easily distinguish it from I. montana, whose posterolateral angles are more developed and subtriangular, and the segment X is rounded and strongly sclerotized (Figs. 36 C – D, pla; 36 L – M).	en	Rosso, Pedro, Campos, Luiz Alexandre (2021): Revision of Ischnopelta Stål, 1868 with the description of twenty new species (Hemiptera: Pentatomidae: Discocephalinae).

(Fig. 26 A – B), differing in the larger size, the antennal length, and the size of the lateral blotches of the urosternites. The fold on the distal half of sutural margins of valvifers VIII in I. magna sp. n. is the characteristic that best distinguish both species (Figs. 5 D; 33 C, vf 8). This folding is also found in I. confusa sp. n. (Figs. 5 C; 17 C, vf 8) though less pronounced, and I. confusa sp. n. differentiates from I. magna sp. n. by the laminate, oblique projections on the posterior margin of urosternite VII (Fig. 17 C, mpr), the unpunctured mesosternum, and the bucculae concealing the first labial segment.	en	Rosso, Pedro, Campos, Luiz Alexandre (2021): Revision of Ischnopelta Stål, 1868 with the description of twenty new species (Hemiptera: Pentatomidae: Discocephalinae).

(Fig. 13 C, X), I. cordiformis sp. n. (Fig. 20 L – M), and I. wigodzinskyi sp. n. (Fig. 48 L – M). However, in I. anangulata the posterlateral angles of the pygophore are not developed (Fig. 13 C – D), in I. wigodzinskyi they are 0.3 times the length of the pygophore (Fig. 48 C, pla), whereas about 0.5 times in I. vellozia (Fig. 46 C – D, pla) and I. cordiformis (Fig. 20 C – 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. 5 M; 47 C, vf 8) than in I. wigodzinskyi (Fig. 5 N, 49 C, vf 8).	en	Rosso, Pedro, Campos, Luiz Alexandre (2021): Revision of Ischnopelta Stål, 1868 with the description of twenty new species (Hemiptera: Pentatomidae: Discocephalinae).

Vesicular area anterior to the collar 1 / 7 of the posterior portion; median duct anterior to the collar with slight proximal widening (Fig. 49 D, mdp); median duct posterior to the collar with proximal and distal widening (Fig. 49 D, md); inner duct coiled in the proximal widening (Fig. 49 D, id). Distal ductus receptaculi of same caliber as the proximal (Fig. 49 D, drd, drp). Pars intermedialisbroader distally (Fig. 49 D, pi); proximal annular crest directed to the ductus receptaculi; distal annular crest perpendicular to the pars intermedialis (Fig. 49 D, dac, pac). Capsula seminalis globose; long and sinuous laterobasal projection surpassing the proximal annular crest; laterodistal projection short (Fig. 49 D, cs, pr).

The segment X on males of Ischnopelta wigodizinkyi sp. n., although cordiform, has the apical margin less emarginated, and the setae denser on the laterobasal margins (Fig. 48 L – M).	en	Rosso, Pedro, Campos, Luiz Alexandre (2021): Revision of Ischnopelta Stål, 1868 with the description of twenty new species (Hemiptera: Pentatomidae: Discocephalinae).
