North and Central American 
Species of Aneurus Curtis 
(Hemiptera: Aradidae) 
By Nicholas A. Kormilev! 
Fifteen species of the genus Aneurus Curtis, 1825, have been re- 
corded for North and Central America. In the present paper five 
additional species are described and a key to the 20 species is presented. 
This study is based on specimens from the U.S. National Museum, 
Washington, D.C., and the American Museum of Natural History, 
New York, N.Y., loaned by Drs. Richard C. Froeschner and Peter 
Wygodzinsky, respectively; and information from types in the British 
Museum (Natural History) furnished by Dr. William J. Knight. To 
all these men I offer my sincere thanks. 
Measurements in this paper were taken with a micromillimeter 
eyepiece; 25 units equal 1 mm. For convenience, the length of the 
abdomen was taken from the tip of scutellum to the tip of hypo- 
pygium in the male and to segment IX in the female. 
There has been some confusion concerning the identity of the 
Florida species, Aneurus politus Say (1832, p. 31). The original 
description made no reference to the important shape of the hypo- 
pygium. On the basis of five specimens from Guatemala, Champion 
(1898, p. 115) gave a short redescription with two drawings (table 7; 
figs. 29, 29a) and remarked about a “small and transverse’ hypo- 
pygium. Comparison of three Florida specimens with three Central
