LACE-BUG GENERA OF THE WORLD 

 (HEMIPTERA: TINGIDAE) « 



By Carl J. Drake and Florence A. Ruhoff 



Introduction 



A treatise of the generic names of the family Tingidae from a global 

 standpoint embodies problems similar to those frequently encountered 

 in corresponding studies in other animal groups. The more im- 

 portant criteria, including such basic desiderata as fixation of type 

 species, synonyms, priority, and dates of technical publications 

 implicate questions concomitant with recent trends toward the 

 clarification and stabilization of zoological nomenclature. 



Zoogeography, predicated and authenticated on the generic level 

 by the distribution of genera and species, is portrayed here by means 

 of tables, charts, and maps of the tingifauna of the world. This 

 visual pattern of distribution helps one to form a more vivid concept 

 of the family and its hierarchic levels of subfamilies and genera. 

 To a limited extent the data indicate distributional concentrations 

 and probable centers of evolution and dispersal paths of genera. 

 The phylogenetic relationship of genera is not discussed. 



The present treatise recognizes 216 genera (plus 79 synonyms, 

 homonyms, and emendations) of the Tingidae of the world and gives
