 Megarthroglossus spenceri Wagner 



Megarthroglossus spenceri Wagner, 1936, Canad. Ent. 68 : 196, pi. 11, figs. 2, 3. 



Type host. — Ochotona princeps (Rich.) (cony). 



Type locality. — Nicola, British Columbia. 



Range. — Known only from British Columbia. 



The original description of spenceri was based on a single female, but 

 is accompanied by a drawing of the forehead and one of the female 

 terminalia. 



The Genus Anomiopsyllus Baker 



(Fig. 12, E) 



Anomiopsyllus Baker, 1904, U. S. Natl. Mus. Ppc. 27: 425. Monotypic. Type, 

 Typhlopsylla nudata Baker. 



Anterior margin of front rounded. Frontal tubercle present, angulate apically. 

 Genal comb absent. Eyes absent. Labial palpus 4-segmented, never extending to 

 tip of trochanter I, well and equally sclerotized along anterior and posterior 

 borders. Antennal club long, segments not anchylosed anteriorly. Antennal 

 groove open posteriorly. Metatborax reduced, being shorter than mesothorax ; 

 upper part of metepisternum, metepimeron, and metanotum fused, without a de- 

 limiting suture or inner ridge between them. Pronotal comb absent. Coxa II and 

 coxa III each with a posteroventral, spinelike lobe separated from coxa proper 

 by a deep incision. Coxa III without a row or patch of spinelets on inner surface. 

 Femora each with not more than a single lateral seta. Segment V of tarsi I and 

 II with 5 pairs of plantar bristles, the first pair being situated between setae of 

 second pair; segment V of tarsus III with only 4 pairs of plantar setae, all being 

 lateral and forming 2 parallel rows. Abdomen much longer than high, without 

 apical spines. Sternal plate VIII of male considerably shortened and without 

 posterior processes. Sternal plate IX of male without anterior apophysis, with 

 a pair of large, expanded, inner, vertical processes, and a pair of more or less 

 flattened, clavate, posterior, spinigerous processes. 



Baker (<5, p. 127), in 1905, established for this genus the subfamily 

 Anomiopsyllinae. Although in this work the genus is not recognized 

 as constituting a subfamily, it is regarded as a somewhat isolated one, 

 particularly in the degree to which the metathorax has been reduced 

 and in the manner in which most of its sclerites have been fused. The 

 mcluded species are all Nearctic. 



Anomiopsyllus amphibolus Wagner 



Anomiopsyllus amphibolus Wagner, 1936, Ztschr. f. Parasiteuk. S: 654, fig. 1. 



Type host. — Neotoma desertorum Merr. (wood rat). 



Type locality. — Salina, Utah.

In this species the movable finger bears two posterior, submarginal, 

 stumplike spines, and sternal plate IX of the male possesses four 

 terminal spines.
