North American species to form a ring through which the penis 
protrudes. Ventrally and anteriorly, 9th sternum has lateral apoph¬ 
yses (except in 2 species not within the area of this study). Ventrally 
and posteriorly, 9th sternum has an unimpaired structure called the 
process of the 9th sternum. Originating anteriorly of the process are 
paired structures called the appendages of the 9th sternum. They are 
usually backwards and dorsally directed, bear hairs at their apical 
ends and are either fused distally or are connected to a transverse 
plate. Appendages of 9th sternum are frequently membranous and 
difficult to delimit. Penis prominent with a pair of dorsolateral 
apodemes and a somewhat conical anterior one. Ectoprocts un- 
sclerotized in all North American species, but sclerotized or other¬ 
wise modified in some other species. 
Female genitalia with ectoprocts often indistinct. Gonapophyses 
laterales forming a sclerotized ventral plate. Bursa copulatrix 
sclerotized and differing interspecifically. 
Notes: The male genitalia of Aleuropteryx differ from those of 
other genera and it is difficult to find homologous structures in 
other genera. The naming of structures in this case is for conveni¬ 
ence and an attempt is made to standardize terminology. This has 
not always been the case in the past (Meinander 1972). 
The shape of the bursa copulatrix and associated structures allow 
the females to be determined to species. 
The larval stages of only one North American species (A. 
juniperi ) is known. 
There are 14 species of this genus within the area of this study, 5 
of which are herein described as new.
