Trichopsylla (Trichopsylla) pekicilliger dissimilis (Jordan), 

 new combination 



Maiaraeus penictiliger dissimilis Jordan. 1988, Novitates ZooL 41: 119, figs. 

 65-66. 



Cotype hosts. — Evi sp. (red-backed mouse) and Microtns sp. 



( meadow mouse | . 



Type local 'If y. — Rapids. Alaska. 



Range. — Known from Alaska and British Columbia. 



The original description of dissimilis is accompanied by a drawing 

 of the male terminalia made by Jordan from a specimen in the United 

 States National Museum. The name dissiwMis was suggested by 

 W. L. Jellison. who has supplied the same museum with a female 

 paratype. It applies to the American representatives of penicilMger^ 

 which differ from the Old World subspecies particularly in that the 

 process of the clasper is longer and the acetabular bristles are 

 smaller. 



Trichopsylla (Trichopsylla) quirini (Rothschild), new combination 



CeratophyUus quirini Rothschild. 1905, Novitates ZooL 12:163. pi. 6. fig. 1. 

 Megabothris quirini Jordan. 1033. Novitates ZooL 39: 77: I. Fox. 1940. Fleas of 



Eastern United States, p. 70, pi. 18, figs. 90. 94. 



Cotype hosts. — Evotomys gap perl (Vigors) (red-backed mouse) 

 and "Evotomys saturatus." 



Type locality. — Red Deer. Alberta. 



Range. — United States. Canada, and Alaska. 



Rothschild based his description of this species on five males and 

 gave a drawing of the male terminalia. I. Fox (1940) gave a re- 

 description of the species (accompanied by figures), which was 

 based on both sexes. Roth-child considered quirini as being closely 

 related to eumolpi^ stating that "the first midtarsal segment is long 

 and hairy as in eirmopU." The peculiar shape of the movable finger. 

 with its broad and deep posterior emargination. identifies the species. 



Trichopsylla (Trichopsylla) sinoma (Jordan), new combination 



CeratophyUus sinomus Jordan. 1925, Novitates Zool. 32: 110. fig. 41. 



Type h ost. — *Mua? 



Type locality. — Paradise. Ariz. 



Range. — Western part of the United States. 



This is a medium-sized, dark-brown species, identified by the 

 characters of the movable finger of the male clasper. which is very 

 broad and somewhat triangular. Its ventral margin is about 

 straight, posterior margin broadly outcurved. and anterior margin 

 broadly incurved. Near the posterior margin is a row of submar- 

 ginal. enlarged, dark setae, the lowest of which is longest, the upper- 

 most next in length, and the two others much shorter and subequal. 



Trichopsylla ( Trichopsylla) telchixum (Rothschild), new combination 

 CeratophyUus telchinum Rothschild, 1905. Novitates Zool. 12: 1":;. pi. S, fig. 21. 



Cotype hosts.— Evotomys gapperi (Vigors) (red-backed mouse) 

 and Sorex rickardsonii Bach, (shrew).
