ASSASSIN BUGS OF THE GENUS GHILIANELLA 



IN THE AMERICAS 



(IIEMIPTERA, REDUYIIDAE, EMESINAE) 



By J. Maldonado-Capriles 1 



This paper brings together and summarizes available data on the 

 genus Ghilianella in the Americas. Descriptions of the genus and 

 subgenera are given, as well as a checklist of the 88 known species. 

 The keys differentiate the 80 species of which specimens were available 

 for study; they are expansions of those published in 1925 by McAtee 

 and Malloch (the fine work of these authors has aided me greatly in 

 the completion of this paper). Among the species treated in the 

 following pages, 15 are described as new, 1 is redescribed, and the 

 ''hypotypes" of 7 others are described. For 32 previously described 

 species, notes are given on specimens examined, and the paper closes 

 with notes on the 8 species not included in the keys. In the illustra- 

 tions (see pp. 407-421) I have tried to keep together similar structures 

 from the various species so that a comparison of them could be made. 



In this paper, the term "hypotype" is used to refer to a specimen 

 herein described and belonging to the opposite sex of the corresponding 

 holotype described by another author. Additional specimens of the 

 hypotype are called "parahypotypes." Thus, I have followed the 

 terminology suggested by Frizzell (1933).
