Ischnopelta magna Rosso & Campos , sp. n. ( Figs. 5D View FIGURE 5 and 33 View FIGURE 33 )
Etymology. The epithet refers to the large size of this species compared to all other in Ischnopelta . Latin magnus = large.
Type Locality. ARGENTINA, Jujuy, Jujuy, [- 24.1946, -65.2971] GoogleMaps .
Holotype. Female. ARGENTINA, Jujuy, Jujuy. Deposited at the Museo Argentino de Ciencias Naturales “Bernardino Rivadavia” ( MACN), Buenos Aires, Argentina.
Description. The overall somatic morphology is as described for I. scutellata , except for the following features. Body densely punctured, brownish. Head. Labium reaching the metacoxae, segment IV dark brown. Labrum inserted posteriorly to half the distance between the anterior margin of the eyes and the apex of mandibular plates. Antennae: segments I to III dark yellowish, segments IV and V dark brown; segments ratio: I>II<III=IV<V.
Thorax. Scutellum reaching the apical angles of urosternite VI. Hemelytra: corium as long as scutellum; conspicuous spot at apex of radial vein. Mesosternum punctured. Pro-, meso- and metapleura dark yellowish and densely punctured. Setae on posterdorsal margin of protibiae as long as the others.
Abdomen. Dark spots at the lateral of urosternites subequal in length and irregular in shape, both wide.
Male. Unknown.
Female. Membrane of hemelytra not reaching the posterior margin of mediotergite VIII, dark-brown, apical margin convex; median portion of posterior margin of mediotergite VIII and of urosternite VII concave; projections on the lateral 1/3 of posterior margin of urosternite VII thick and perpendicular to the surface of the urosternite ( Fig. 33C View FIGURE 33 , mpr). Genitalia. Valvifers VIII as wide as long; posterior margin sinuous; sutural margins slightly convex and folded dorsally; surface dark yellowish with punctures and brown blotches, longitudinal grooves narrow and shallow on basal surface, wide and deep groove forming a fold on the distal half of sutural rim, setae sparse on posterior half of sutural margins ( Figs. 5D View FIGURE 5 ; 33C View FIGURE 33 , vf8). Valvifers IX covered by valvifers VIII. Laterotergites IX not reaching the posterior margin of mediotergite VIII; visible portion dark yellowish with brown punctures ( Fig. 33C View FIGURE 33 , la9). Internal genitalia not examined.
Measurements: Table 14.
Distribution. Argentina (Jujuy) ( Fig. 7 View FIGURE 7 ).
Comments. Ischnopelta magna sp. n. ( Fig. 33A–B View FIGURE 33 ) is similar to I. cylindrata sp. n. ( Fig. 26A–B View FIGURE 26 ), 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. 5D View FIGURE 5 ; 33C View FIGURE 33 , vf8). This folding is also found in I. confusa sp. n. ( Figs.5C View FIGURE 5 ; 17C View FIGURE 17 , vf8)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. 17C View FIGURE 17 , mpr), the unpunctured mesosternum, and the bucculae concealing the first labial segment.
