Additional specimens.

BRAZIL, Santa Catarina, Corupá Municipality, x. 1944, 01 male; Nova Friburgo, Cascatinha neighborhood (22°20'S, 42°33'W, ca. 1000 m a.s.l.), 19.xii.2003, 01 female, (MNRJ).

Diagnosis.

General coloration blackish to brownish black, sometimes with subtle bluish luster, mainly on sternites. General coloration of corium, clavus and basal portion of membrane of hemelytra orange to reddish orange. Labial segments III and IV, coxae, trochanters, tibiae and tarsi distinctly or extensively marked with pale to yellowish pale markings. Pale markings of connexivum large, occupying approximately basal half of each segment. Several long stiff dark setae on ventral surface of femora, mainly on fore and mid femora, implanted in small rounded tubercles.

Addition to the original description.

Male. Figures 1-17. Measurements (holotype /additional male): total length: to tip of hemelytra: 10.7 / 11.0; to tip of abdomen: 10.2 / 10.4; abdomen maximum width: 3.0 / 3.2.

Coloration: general coloration blackish to brownish black, sometimes with subtle bluish luster, mainly on sternites (Figs 1-3). Head with the following pale to pale yellowish parts: base and a submedian distal ring, somewhat variable in extent on antennal segment I; apex of antennal segment II; most of basal two-thirds of labial segment III (second visible), and apices of the labial segments III and IV. Posterior margin of hind lobe of pronotum somewhat paler in the additional male (Fig. 3). Apex of prosternal process paler. Coxae pale yellowish in approximately apical two-thirds. Trochanters pale yellow with apices darkened. Mid and hind femora with moderately large, subbasal, pale yellow rings. Fore femora with a small, almost imperceptible, paler, subapical spot, dorsally. Mid femora with a narrow, interrupted or incomplete, subdistal pale ring. Tibiae with a narrow, pale, subbasal ring. Fore and mid tibiae with apical half paler, of variable extent around the segment. Tarsi generally pale to pale yellow, with segments II and III darkened at base and apex. Hemelytra (Figs 1, 3): most of corium and clavus and basal portion of membrane orange to reddish orange; corium and clavus darkened to blackish in basal portion; most of membrane blackish with a median apical large pale yellow spot, somewhat enlarged towards apex, and somewhat larger in the additional male. Connexivum with approximately basal half of segments III–VII pale to pale yellow (Figs 1, 3).

Structure and vestiture: generally as in generic description. Tip of scutellum horizontal, directed backwards. Several long stiff dark setae on ventral surface of femora, mainly on fore and mid femora, implanted in small rounded tubercles. Hemelytra covered with numerous adpressed setae on costal area and numerous and longer stiff setae on veins of corium, surpassing abdomen by about half a millimeter.

Male genitalia (in addition to generic characteristics described above) (Figs 4-17): both subapical processes of parameres spiniform. Dorsal phallothecal sclerite (dps): very curved in lateral view at basal third (Figs 9-11); flat lateral expansions of the mid third (fle) prolonged laterally to approximately half the distance between dorsal and ventral surfaces (Figs 10-11, 14); left (in dorsal view) flat lateral expansion somewhat more than half the width of opposite flat lateral expansion (Figs 10-14); apical third of dorsal phallothecal sclerite almost straight in lateral view (Figs 9, 11). Diameter of subapical tubular projection of endosoma wall (stp) roughly uniform, with a half-hemispherical process (hhp) inside its apical portion (Figs 10-14), which is covered by several small sclerotized components, some of which are acutely spined (Fig. 16). Endosoma wall with a small rounded globose lobe laterally (gl), located just ventrally to apex of larger flat lateral expansion of dorsal phallothecal sclerite (Figs 12, 14).

Female. Figure 18. Measurements: total length to tip of abdomen: 12.5; abdomen maximum width: 4.0. Similar to male. Hemelytra not surpassing abdomen, ending shortly after posterior margin of dorsal portion of segment VIII; pale yellow distal spot of the membrane somewhat larger at basal half, subrounded. Abdomen larger; dorsal connexival segments somewhat more evident.

Distribution.

Brazil, in states of Rio de Janeiro and Santa Catarina.
