Tonioplagia pseudopenicillata, new species 



Figures 93; 97, fc; Plate 19, figure 4 



Hendel (1914, p. 39) described his Peruvian species penicillata as a 

 member of the pleuralis group. The characters of the male given by 

 Hendel, in the very short original description and in his key to the 

 species of Tomoplagia, agree completely with the characters of one 

 male specimen in the material of the U. S. National Museum from 

 southern Brazil. This Brazilian specimen, however, belongs to the 

 atimeta group, having three brownish black spots on the subshining 

 and bare hind margin of the mesonotum: the usual lateral pair, and 

 one double spot at the middle, with posterior margin distinctly 

 attaining the scutellar suture. Since penicillata Hendel has not been 

 discussed by other authors after the first description, there is a possi- 

 bility that the Brazilian specimen does not represent a species distinct 

 from penicillata, if the absence of median black spot is not a constant 

 character in the latter. Nevertheless, taking into consideration the 

 mentioned character which Hendel thought important and which is 

 regarded generally as constant structural character, furthermore the 

 geographical distance, in order to avoid confusion which may be caused 

 by two distinct kind of penicillata, the writer prefers, although unwill- 

 ingly, to describe the Brazilian specimen as a new species. The com- 

 parison of the type specimen of the penicillata Hendel in the Hungarian 

 National Museum with the description given below, or with Peruvian 

 material, will be necessary to settle definitely the status of pseudo- 

 penicillata.
