AMERICAN SPECIES OF THE LACEBUG 

 GENUS ACALYPTA (HEMIPTERA: TINGIDAE) 



By Carl J. Drake ^ and John D. Lattin^ 



Introduction 



The American species of the genus Acalypta have been in need of 

 revisional study for years because of synonyms and confusion of its 

 members in the Hterature and collections. The genus, with the 

 exception of a Mexican indigene, is Holarctic in distribution and as the 

 world species now stand, 10 full species are recognized from North 

 America and 27 from the Palearctic region. The subspecies and 

 varieties are not included in these tabulations. Species inhabiting the 

 coastal region of northern Africa fall into the Mediterranean subregion 

 of Holarctica. 



StM (1873) described the first American form as Acalypta thomsonii 

 (pi. 8) from South Carolina. A total of nine species are known from 

 the United States (including Alaska) and four of these are shared with 

 Canada. The two Alaskan species, A. nyctalis and A. lillianis, are 

 widely distributed in the United States and Canada. Only one 

 species, A. mniophila (pi. 5), inhabits Mexico (central part) and it is 

 known solely from the type specimen. The latter is the only American
