SIPHONAPTERA (FLEAS) COLLECTED FROM SMALL MAMMALSIN MONTANE SOUTHERN UTAH
James R. Kneer} and Glenn E. Haas2
Key tlXJnl.s: fleas, Siphonaptera, Utah, nutfnflUlls.
Recent collections from various small mammals of southern Utah have helped to elucidatethe distribution of fleas (Siphonaptera) withinthe state, ofspecial interest were fleas of mammals found in forested, high-mountain areas ofthe southernmost part ofUtah-,an area ofcomplex topography containing habitat vaIying fromlow desert to subalpine coniferous forests. Inparticular, we sampled the small mammal fleafauna of the Abajo Mountains (San JuanCounty), the La Sal Mountains (GrandiSan Juancounties), and the Pine Valley Mountains(Washington County), These ranges have beensparsely surveyed in this respect, as evidencedby review of the seminal work of Stark (1959),After excluding 22 records (13 00,37 9 9) ofthe ubiquitous deer mouse fleaAethecawagneri(Baker), which occurs in all counties of Utah(Beck 1955), we present and discuss the signif~
icance of 42 new records of 12 species of fleas.A parallel survey offleas found in mammal nestswill be presented elsewhere (Haas and Kucera,in preparation),
Mammal nomenclature is that of Hall(1981), However, designations of long-tailedvole subspecies should be considered tentativebecause of the present confused state of theirtaxonomy. Mammals were collected with Sherman live-traps at all localities exeept Pinescampground, Pine Valley Mountains, and snaptraps were used at all three localities in the PineValley Mountains and at Oowah Lake campground, La Sal Mountains, An asterisk (')denotes that the host specimen (or at least onehost specimen) was depoSited in the mammalcollection of the University of Utah Museum of,

Fleas ofthe genus Hysirichopsylla aI'e foundon a variety of small mammals in mesic to moisthabitats, These are the first records ofH, dippieitron-cata from southeastern Utah. Campos andStark (1979) record H, 0, sylvaticus from SanJuan Co., but our records of this taxon are thefirst from southwestern Utah.
Corrodopsylla curvata curvata(Rothschild, 1915)
Sorex palustris navigator (Baird)', GrandCo,: LaSal Mts" meadow at Oowah Lake, 2769m, 15 June 19m: 13, 11' from each of twoshrews.
The only previous published records fromUtah of C, c, curoota are both from northernUtah: Rich Co, (Bear Lake; collection by Stanford published by Tipton ;md Allred [1951:107]) and Salt Lake Co, (Wasatch Mts,; Egoscue1988), These records are from unidentified

1992] NarES 383
Sorex spp. Records of C. c. obtusata ex watershrews are given from Tooele Co. by Egoscue(1966, 1988). Published records ofC. c. curoatafrom southwestern states are sparse: Haas et al.(1973) record it £i'om New Mexico. Additionalcollecting may reveal its presence in the AbajaMts., since water shrews are known to occurthere (Schafer 1991).
RhadinopsyUa se<-tilis sectilis(jordan & Rothschild, 1923)
PeromrJseus maniculatus sotuJriensis. Washington Co.: Pine Valley Mts., North Juniper Parkcampground, 2119 m, 10 November 1991; Ie.
This species is known from only one area ofsouthern Utah (Garlleld Co., vic. Panguitch,Stark 1959), but not previously from southwest·ern Utah. This specimen possesses 5 spines inthe genal comb, as do other Utah specimens(Stark 1959, and unpublished data), but cbarac·ters of the genitalia are clearly refemble to R. s.sectilis mther than R. s. goodi (Hubbard 1941).Stark (1959) noted that the genal spine numberof Utah specimens is not consistent with theoriginal description of R. s. sectil;.,.
CataUagia decipiens Rothschild, 1915

These are apparently the llrst specillcrecords published for that part of Utah south ofthe Colorado River. Beck (1955: Table 3) lists itas occurring in San Juan County.
PeromyscopsyUa selenis (Rothschild, 1906)
Peromyscus manicolatus rofinus. San JuanCo.: Abajo Mts., Dalton Springs cmnpground,2560 m, 8 September 1991; 1 c. Microtuslongicaudus alttcolo·. idem, 1 c. M. I. altimla.idem, 1 'f. M. I. lotus. Washington Co.: PineVaney Mts., Pines campground, 2079 01, 12June1991; 2 cc, 1 'f.
This species was not previously known li'omUtah south of the Colorado River. Johnson andTraub (1954) give a record from Iron County,bordering Washington County to the north.This species is most commonly collected fromMicrotus spp., but ,Jso from other small mam·mals sympatric with the voles.
PeromyscopsyUa hespero71lYs adelpho(Rothschild, 1915)
Peromyscus manU-ulatus fl;,ftnus. GrandCo.: LaSal Mts., Oowah Lake campground,2682 m, 15 June 1991; 1 c, 2 'f 'f.
Johnson and Traub (1954) record this spe·cies from Beaver, Box Elder, Millard, San Juan,and Washington counties.
Opisodnsys keelli (Baker, 1896)

. No known records ofthis species from southern Utah are published other than that of Hub·bard (1947:111, Garfield Co.). Stark (1959)noted that this species is collected only in moun·tainous areas or moist habitats. We have ...usofound this to be true (unpublished data). Per·O1nysr....us spp. are the usual host.
Malaraeus telchinns (Rothschild, 1905)
Peromyscus maniculatus sOfuniensis, Washington Co.: Pine Valley Mts., N Juniper Parkcampground, 2119 m, 10 November 1991; 2C c, 1 'f. P. m. s01lOriensis. idem, 1 c, 1 <;>. P.m. sonorien.W. idem, 2 9 9. P. m, sonoriensis.idem, 1 'f. PeromysCtls boyIii rowleyi. idem, 1'f.

Beck (1955: Table 3) lists Malaraetlstelchinus as occurring in Washington County.Hubbard (]947: 200) gives the only specillcrecord from southern Utah (Garfield Co.).Huwever. several records of M .. sino11UtS fromdesert areas ofsouthern Utah are given by Stark

(959). Also, many specimens of M. sinomusfrom Peromyscus crinitus were taken by thesenior author in Snow Canyon (Washington Co.)incidental to the search for Traubella gnmdmanniEgoscue, 1989. M. telchinus seems to be like O.keeni in being found only in nondesert habitat.
Megabothl1S ahan!is (Rothschild, 1905)
Micro/us longicaudus alticola. Grand Co.:LaSal Mts., meadow at Oowah Lake, 2676 m,14 June 1991; 10,1'< . Peromyscus maniculatusrufillus. idem, 1 '<. M.l. alticola. idem, 1 2.

Beck (1955: Table 3) listed this species asoccurring in Beaver, Iron, Sevier, and Waynecounties. This was apparently overlooked byStark (1959: 196), who stated, "This flea appearsconfined to the northern half of the state."Egoscue (1988) reported collecting one malespecimen from a pika at Johmon ReselVOir,Sevier County, in south central Utah. The distribution map of Haddow et a!. (1983: Map 76)indicates a locality record in that same region ofUtah. Our records are the first for southeasternUtah. Megabothris ahantis is usually found onvarious species of Microtus.
Eumolpianu.s eunwlpi americanus(Hubbard, 1950)
Tamias sp. San Juan Co.: Abajo Mts., DaltonSprings campground, 2560 m, 8 September1991; 222.
These specimens seem closer to E. e. americonus than to E. e. eumolpi recorded by Beck(1955, then in the genus MOllopsyllus). Severalof the type specimens were collected in SanJuan County (Hubbard 1950). Johnson (1961)indicates that intergradation bet.weenE. e. amencmws and E. e. eumalpi occurs in the county.
In summary, the significant findings among64 collection records of 13 species of fleas are asfollows: the first records south of the ColoradoRiver in southeastern Utah for Hystrichopsylladippiei truncata, Corrodopsylla c. eurvata, Peromyscopsylla selenis, and Megahothris ahantis;and the first in Washington County, southwestern Utah, for H. occidentalis sylvatieus, Rhadi1lOpsylla s. sectilis, P. selenis, and OpisodJJsys keen;
