Type data. — Holotype is in the Museu Nacional do Rio de Janeiro. 

 Carvalho listed the type locality as Sernambetiba, Distrito Federal, 

 Brazil. 



Specimens studied: 1 female. 



Brazil: Sao Paulo, A. A. Barbiellini. 1 female (USNM). 



Discussion. — S. giselleae is quite distinct within the genus on several 

 characters: The numerous tubercles on the hind tibia, the very short 

 wing membrane which falls short of the apex of the abdomen, and 

 the small ocelli which are separated from the nearest eye by a space 

 distinctly more than the transverse diameter of an ocellus. 



With his original description of this species Carvalho reported 

 that the type material was collected on July 7, 1951, 



by Miss Giselle Machilne who collected them when digging between a type of 

 vegetation dominated by Diplothemium maritimum Martuis, a dwarf palm and 

 a prairie type of vegetation. There were collected altogether 15 specimens in 

 different phases of development, about one hundred meters from the tide line and 

 two meters below the surface of the soil. The bugs were probably feeding on the 

 roots of Telanthera maritima Moq. since they were found around a gall of about 

 the size of a human wrist. A strong odor was noted when handling them.

Diagnosis. — The very broad eyes (one of which equals or exceeds 

 one-third of the interocular width) separate this species from others 

 within the genus. 



Description. — Color: Light brown to brown, apices of anterior 

 tibiae and marginal tubercles of corbicle of posterior tibiae fuscous to 

 black. 



Male: Head: Wider than long, 1.67(1.63-1.72): 1.37(1.33-1.43); 

 interocular width, 0.96(0.86-1.00); width of eye, 0.36(0.34-0.38); ocel- 

 lus large, separated from eye by less than ocellar width; clypeus 

 narrow, parallel-sided, reaching or slightly surpassing apices of juga. 

 Antennal segments: I, 0.40(0.40-0.43); II, 0.42(0.40-0.46); III, 0.43 

 (0.40-0.50); IV, 0.62(0.60-0.66). Labial segments : I, 0.49(0.46-0.56); 

 11, 0.56(0.53-0.63); III, 0.36(0.33-0.40); IV, 0.35(0.33-0.36). 



Pronotum: Length-width ratio, 2.39(2.10-2.63) : 3.97(3.63-4.20); 

 transverse rugae distinctly punctured. 



Scutellum: Length-width ratio, 3.28(3.11-3.43) :2.50(2.25-2.75); 

 surface more or less distinctly punctured. 



Hemelytron: Corium polished, with numerous, fine to moderate 

 punctures; membrane surpassing apex of abdomen by more than half 

 its length.
