Type material examined. Holotype ♂, BRAZIL, Santa Catarina, Nova Teotônia , Seara, XII.1939, F. Plaumann leg. ( AMNH) <illustrated specimen >. Paratypes: BRAZIL, Santa Catarina, Nova Teotônia , Seara, ♂ <illustrated specimen>, 2♀, IX.1939, F. Plaumann leg. ( AMNH); same data, ♀, 300–500m, 24.IX.1966 ( USNM); same data, 2♀, V.1967 ( AMNH); same data, ♀, X.1969, L.H. Rolston coll. ( AMNH) <illustrated specimen >.

Diagnosis. Mandibular plates longer than clypeus; lateral margins of mandibular elevate in relation to the plan of mesial margins. Proportions of antennomeres: 1> 2 <3> 4 <5 ( Fig. 185 ). Median labium, reaching the mesocoxae. Proportions of labiomeres: 1 <2> 3> 4 ( Fig. 190 ). Processes of anterior angles of pronotum obtuse. Anterolateral margins of pronotum crenulate; posterior margin of pronotum straight ( Fig. 188 ). 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 of mesopleuron reaching more than half of the segment and less half of metapleuron, present in posterior lateral angles and absent in a diagonal from mesepimeron to mesepisternum. Anterolateral margin of evaporatorium tapered. Outer margin of metapleural evaporatorium straight. Gyrification of evaporatorium with low wrinkles. ( Figs 191–193 ). Metathoracic spiracle wide ( Fig. 191 ). Hemelytra surpassing the abdominal apex ( Fig. 185 ). Spiracles black. Mesial area adjacent to spiracles with callosity ( Figs 186–187 ).

Measurements. See Table 1 .

Male genitalia. Posterolateral angles of pygophore quadrate. Genital cup broad, occupying more than half of pygophore length. Middle region of dorsal rim entire. Extension of dorsal rim well-developed. Area between layers of ventral rim excavated, separated by a carina ( Fig. 197 , black arrow). Superior layer of ventral rim with two pairs of processes ( Fig. 195 ); lateral margin of superior layer notched, in superior view. Inferior layer of ventral rim without process. Segment X ogival (rectangular with arcuate apex), not carinate, with tumescence basally ( Figs 194–197 ). Parameres present, crown reduced ( Fig. 194 ). Phallus ( Figs 198–200 ): Dorsal connectives shorter, not reaching the distal half of phallotheca. Processus capitati long. Phallotheca wider than long. Dorsal processes of phallotheca uniformly wide, straight, and longer relative to posterodorsal projections. Conjunctiva with two pairs of processes, one membranous and one sclerotized ( Fig. 200 ), and three pairs of lobes, median lobe sclerotized. Ductus seminis distalis longer.

Female genitalia. Valvifers 8 convex, at least twice as much in length to laterotergites 9, posterior margins sinuous. Valvifers 9 flat, with anterior and posterior margins straight; sclerotized lateral arms attaining anterior margins of laterotergites 9. Posterior margins of laterotergites 8 obtusely projected; each lateral margin with process. Mesial margins of laterotergites 9 divergent, posterior margins obtusely projected, not surpassing abdominal tergite 8 ( Fig. 201 ). Ectodermal ductus ( Fig. 202 ): Proximal ductus receptaculi twisted, short, in relation to vesicular area, greater diameter. Distal ductus receptaculi straight, shorter than vesicular area. Annular flanges divergent related to each other. Anterior annular flange smaller than pars intermedialis and posterior annular flange thinner in relation to capsula seminalis . Capsula seminalis globose.

Distribution. Brazil (Santa Catarina) ( Fig. 184 ).
