ANOMIOPSYLLUS NOVOMEXICANENSIS, new species 



Figure 66, a-d 



Head : Frontal tubercle present, head apically angulate ; in the 

 male, dorsal margin of head somewhat flattened or depressed be- 

 tween the tubercle and cervicum. Genal armature of two slender 

 bristles, one at the edge of antennal groove and the other near the 

 midventral margin of the gena, with a short and very weak seta 

 midway between the two. Postantennal region nude with exception 

 of small setae at lower marginal angle. Bristles of the second an- 

 tennal segment short in both sexes. The antenna of the male long 

 and slender, shorter and stouter in the female. Labial palpi ex- 

 tending to about the distal margin of the f orecoxae or slightly be- 

 yond; maxillary palpi often slightly longer. 



Thorax : As in the genus. 



Legs: Each of coxa II and III with a posterodistal spinelike 

 lobe separated from coxa proper by a deep incision. Coxa III with- 

 out a row or patch of spinelets on inner surface. Segment 5 of tarsi 

 I and II with five pairs of plantar bristles, the proximal pair being 

 situated medially between the bristles of the next two pairs or more 

 nearly between the bristles of the second pair; fifth segment of 

 tarsus III with only four pairs of plantar bristles, all lateral and 

 forming two parallel rows. 



Abdomen: Two anterior tergites usually with a few apical 

 spinelets, in a few instances only on the first tergite ; all tergites 

 with a single row of weak setae. One well-developed antepygidial 

 bristle on each side. 



Modified segments, male : Sternite IX (fig. 66, a) of male bearing 

 two black spiniforms near the tip and slightly proximal a longer 

 and clear spiniform. Finger (fig. 66, b) subtriangular, wide at 

 base and becoming narrow at tip ; position of setae as in the figure ; 

 with three black spiniforms subevenly spaced near the posterior 

 border. Process of clasper lobelike, directed dorsally, the posterior 

 border rounded and with three setae. 



Modified segments, female : Sternite VII as shown in figure 66, c. 

 Spermatheca (fig. 66, d) has a rounded body and a crooked tail. 

 Stylet about three times longer than wide, with one long bristle and 

 two very short apical setae.

Type locality. — Six miles east of Albuquerque, at west foothills 

 of Sandia Mountains, Bernalillo County, N. Mex. Male holotype, 

 female allotype, 332 male paratypes, and 605 female paratypes

 Allen) collected on October 10, 1948; from nests of the same 

 rodent, 62 male paratypes, and 126 female paratypes on February
