Type material examined. Holotype ♂ , BRAZIL , Rio de Janeiro , Marechal Jardim , Inundações da Paraíba , 1.I.1946 , P. Wygodzinsky leg. ( USNM ) <illustrated specimen >. Paratype : BRAZIL , Rio de Janeiro , ♀ , Marechal Jardim, Inundações da Paraíba , 1.I.1946 , P. Wygodzinsky leg. ( USNM ) <illustrated specimen >. Diagnosis. Mandibular plates longer than clypeus. Proportions of antennomeres: 1> 2 <3 <4 <5 ( Figs 17 , 136 ). Short labium, reaching between the pro- and mesocoxae. Proportions of labiomeres: 1 <2 <3> 4 ( Fig. 17 ). Anterolateral margins of pronotum crenulated ( Fig. 3 ). Each peritreme of ESES reaching about 1/3 of the distance to lateral margin of evaporatorium; median furrow of the peritreme long, reaching more than half of peritreme; evaporatorium on mesopleuron reaching more than half of the segment and less half of metapleuron, present in posterior lateral angles. Anterolateral margins of evaporatorium rounded. Each outer margin of metapleural evaporatorium, convex. Gyrification of evaporatorium with low wrinkles. Metathoracic spiracle narrow. Hemelytra surpassing the abdominal apex. Spiracles black ( Fig. 139 ). Mesial area adjacent to spiracles without callosity (inconspicuous) ( Figs 18 , 137, 139 ). Measurements. See Table 1 . Male genitalia. Posterolateral angles of pygophore quadrate. Genital cup occupying half of pygophore length. Middle region of dorsal rim entire. Extension of dorsal rim obsolete. Area between layers of ventral rim excavated, not separated by a carina. Each lateral margin of superior layer entire, in superior view. Inferior layer of ventral rim with a process. Segment X “pear-shaped”, carinate ( Figs 33–35 , 140–142 ). Female genitalia. Valvifers 8 convex, subequal in length to laterotergites 9, posterior margins convex. Valvifers 9 depressed, with posterior margins convex. Posterior margins of laterotergites 8 acutely projected. Mesial margins of laterotergites 9 convergent, posterior margins obtusely projected ( Fig. 50 ). Distribution. Brazil ( Rio de Janeiro ) ( Fig. 184 ).
