Introduction 
Under the abbreviated system used here the literature references are 
cited by author, year, and key letter, e.g. Fabricius 1802a. The full refer- 
ence can be obtained by consulting the Bibliography of the Cercopoidea in 
which authors are arranged alphabetically and their works chronologically 
under the author’s name. This method of citation eliminates the necessity 
for a complete literature citation in the catalogue proper. 
The Family Clastopteridae consists of two genera and eighty-five species. 
This family may be characterized as follows : Eyes with horizontal diameter 
greater than vertical diameter; pronotum with anterior margin strongly 
convex or subangulate, anterolateral margins usually short; scutellum flat, 
not spinous, longer than pronotum ; fore wing with clavus obtuse or obliquely 
truncate at apex. 
The following classification has been adopted for this family:

With the exception of two species which have been reported from the 
Malaysian Region, the species in this family are confined to North and 
South America. Thirty-two have been reported from the Neotropical 
Region, twenty-seven from the Nearctic Region, twenty from the Carib- 
bean Region, and four from two or more regions. 
The known geographic distribution of each species is indicated by super- 
script figures at the end of the lines, which correspond to geographic regions 
designated by the same superscript figures. In general the distribution is as 
given by the author of the reference, using the country as the smallest unit 
except in the larger countries where states and provinces are used as the 
smallest units. In the larger island groups the individual islands are indicated 
wherever possible in view of the importance of island endemism.
