NORTH AMERICAN ACROLOPHIDAE — ^HASBROUCK 571 



A. klotsi is related to popeanellus, the two comprising a small species 

 group characterized in the foregoing remarks on popeanellus. These 

 two species may be easily distinguished from each other, as well as 

 from all other acrolophids, on the basis of their aedeagi and unci. In 

 klotsi, the vesica of the aedeagus is armed with only one large cornutus 

 as compared with the two large clusters of cornuti in the vesica of 

 popeanellus. Likewise, in klotsi, the furcae of the uncus, although 

 curving strongly ventrad, are neither expanded nor flattened like 

 those of popeanellus. Lastly, the labial palpi of klotsi are somewhat 

 shorter than those of popeanellus. The genital characters of klotsi 

 are consistent throughout my fairly large series and they are quite 

 distinct from those of all the other species treated here. 



This species is named in honor of Dr. Alexander B. Klots, Kesearch 

 Associate in the Department of Insects and Spiders at the American 

 Museum of Natural History. Dr. Klots has supplied me with a 

 large series of acrolophids, which included representatives of a number 

 of new species.
