Female: Similar to male, but anterior and posterior femora without 

 armature described for that sex. 



Head: Length-width ratio, 0.48(0.44-0.51) : 0.60(0.57-0.63); inter- 

 ocular width, 0.35(0.34-0.40). Antennal segments: I, 0.13(0.13-0.15) ; 

 II, 0.03(0.03-0.04); III, 0.22(0.22-0.23); IV, 0.20(0.19-0.22); V, 

 0.23(0.23-0.24). Labial segments: I, 0.22(0.21-0.23); II, 0.25(0.23- 

 0. 27); III, 0.25(0.23-0.27); IV, 0.21(0.20-0.23). 



Pronotum: Length-width ratio, 0.79(0.72-0.86) : 1.40(1.35-1.31). 



Scutellum: Length-width ratio, 0.56(0.53-0.61) :0.62(0.60-0. 66). 



Length of body: 2.28(2.15-2.47). 



Type data. — Holotype male (JCL) and allotype female (JCL), 

 "Nova Teutonia. Sta. Catarina, Brazil, X-II, 1952, F. Plaumann." 

 Paratypes: Same data as types but various dates: 5 males, Aug. 8, 

 Sept. 24, and Oct. 11; 8 females, Aug. 8, 18, Oct. 5, 9, 11, 14, 23 (all 

 JCL). 



Discussion. — The prominent, blackened fovea near the base of the 

 prosternal carinae suggested the specific name.

 1893, p. 75. 



Diagnosis. — Among the species with five jugal pegs, this species 

 may be recognized by its hemelytral color — the clavus and basal 

 area of the mesocorium are much lighter than the exocorium and apical 

 part of the mesocorium; or structurally it is separable from all the 

 above-mentioned species by having the mesocorial disc sparsely but 

 evenly punctate for its full length, i.e., without a submedian, impunc- 

 tate area. 



Description. — Based on one male and one female. Male: 

 Elongate, sides subparallel. 



Head: Length more than three-fourths width, 0.54:0.65; inter- 

 ocular width, 0.39; clypeus slightly surpassing juga; latter with five 

 marginal pegs, anteocular part polished, impunctate. Antennal 

 segments: I, 0.18; II. 0.07; III, 0.35; IV, 0.27; V, 0.30. Labium reach- 

 ing bases of middle coxae. Labial segments: I, 0.20; II, 0.26; III, 

 0.35; IV, 0.23. 



Pronotum : Length more than half width, 1 .09 : 1 .66 ; anterior margin 

 deeply concave, anterolateral angles truncated behind eyes; lateral 

 margins straight and slightly converging on basal half, thence broadly 

 rounded to apex; transverse impression deep, sinuate, punctate; 

 anterior lobe with subapical band of coarse punctures, with few 

 scattered minute punctures on midline and calli and laterally with one 

 or two rows of punctures finer than those of transverse impression;
