Calisiopsis brasiliensis, new species 



Calisiopsis ampliceps Kormilev (not Champion), Anal. Soc. Cient. Argentina, vol. 

 162, nos. 5, 6, p. 149, figs. 1-3. 



Since the detailed description of the male was given in my previous 

 paper (Kormilev, 1956, p. 149), I repeat here only the comparative 

 ratios. 



Male: Head shorter than wide through the eyes (male 17:24; 

 female 16:25.5); anterior process relatively longer and narrower 

 (20:13); the proportions of antennal segments (1 to 4) are: male 

 3:5:4:19; female 3:5:3:18; pronotum shorter than wide across the 

 humeri (male 19:38; female 19:41); scutellum longer than wide at 

 the base (male 49:33; female 51:36); abdomen shorter than wide 

 (male 43:46; female 44:50). 



Size: Total length: male, 3.00 mm., female, 3.34 mm. Width of 

 pronotum: male, 1.24 mm.; female, 1.37 mm. Width of abdomen: 

 male, 1.50 mm.; female, 1.67 mm. 



Holotype: Male, Nova Teutonia, Santa Catarina, Brazil, Dec. 8, 

 1940, F. Plaumann; deposited in the collection of the author. 



Allotype: Female, locality and collector same as for holot3^pe, 

 collected Dec. 1, 1940; in the collection of the author. 



Paratypes: One male and one female, locality and collector same 

 as for holotype; one female, Porto Alegre, Rio Grande do Sul, Brazil, 

 Rev. P. Buck, S. J. 



Remarks: Calisiopsis brasiliensis, new species, differs from C. 

 ampliceps Champion, 1898, principally in having a more robust and 

 relatively wider body; relatively larger eyes that are placed much 

 higher (seen from the front, two-thirds above the level of the vertex) ; 

 and different proportions of the antennal segments.
