( MCNZ – 180207) <illustrated specimen >; ARGENTINA , Colón , ♂ , II.1990 ( MACN – 28123) . Diagnosis. Mandibular plates longer than clypeus; mesial margins of mandibular plates not contiguous in relation to clypeus ( Fig. 62 ). Proportions of antennomeres: 1> 2 <3 <4 <5. Posterior margins of bucculae reaching base of head. Labium short, ending between pro- and mesocoxae. Proportions of labiomeres: 1 <2> 3> 4 ( Fig. 61 ). Each peritreme of ESES reaching about 2/3 of the distance to lateral margin of evaporatorium, median furrow of the each peritreme long, reaching more than half of peritreme; evaporatorium on mesopleuron reaching less than half of the segment, and present in a diagonal from mesepimeron to mesepisternum. Gyrification of evaporatorium with high wrinkles. Metathoracic spiracle wide. Hemelytra surpassing abdominal apex ( Figs 55 , 60 ). Connexivum concealed, angles concolour with dorsal color ( Figs 55 , 60 ). Spiracles circular, spiracle of abdominal sternite 2 not covered by metathorax. Mesial area adjacent to spiracles without callosity ( Fig. 63 ). Measurements. See Table 1 . Male genitalia. Posterolateral angles of pygophore quadrate ( Figs 64–66 ). Genital cup opening occupying less than half the length of pygophore. Extension of dorsal rim well-developed over segment X ( Fig. 64 ). Layers of ventral rim not separated by a carina; area between layers excavated. Inferior layer of ventral rim with a pair of processes ( Fig. 65 ). Phallus ( Figs 67–70 ): Dorsal connectives longer, surpassing the distal half of phallotheca . Processus capitati short, not reaching phallotheca distal margin. Dorsal processes of phallotheca uniformly wide, longer than posterodorsal projections. Female genitalia. Valvifers 8 convex, posterior margins sinuous. Valvifers 9 flat, with anterior margins straight and posterior margins convex, sclerotized lateral arms not attaining anterior margins of laterotergites 9. ( Figs 48 , 71–72 ). Proximal ductus receptaculi convoluted, long in relation to the length of vesicular area, at least two times longer. Distal ductus receptaculi convoluted, long, at least one time longer than vesicular area. Annular flanges convergent related to each other. Capsula seminalis globose (see Fernandes & Grazia, 1996: 351 , fig. 36). Distribution. Brazil ( Santa Catarina , and Rio Grande do Sul ); Argentina ( Buenos Aires ) ( Fig. 111 ).
