As part of a continuing and more general study of the diversity of parasites from subterranean mammals in central North America, individuals of the Plains Pocket Gopher, Geomys bursarius bursarius, were collected from 7 localities in northwestern Minnesota from September 1991 through October 1996. Arthropods collected included the fleas, Opisocrostis bruneri (4 of 124, 3.2\%), Foxella ignota ignota (85 of 124, 68.5\%); the chewing louse, Geomydoecus geomydis geomydis from 98 of 124 (79\%), and larvae of the tick, Dermacentor variabilis (1 of 124, 0.8\%). Nematodes found included Physaloptera limbata (2 of 118 gophers, 1.7\%), Capillaria americana (4 of 118, 3.4\%), and Ransomus rodentorum (31 of 118, 26.3\%). Cestodes recovered included Anoplocephaloides infrequens (12 of 136 gophers, 8.8\%), Anoplocephaloides variabilis (19 of 136, 14\%), Andrya macrocephala (20 of 136, 14.7\%), and Hymenolepis weldensis from 12 of 136, 8.8\%. The acanthocephalan, Moniliformis clarki was found in 1 of 118 gophers (0.8\%). No parasites were found in the cheek pouches, thoracic, or peritoneal cavities.

Here, we develop a Bayesian framework for the analysis of cospeciation. We suggest a simple model of host switching by a parasite on a host phylogeny in which host switching events are assumed to occur at a constant rate over the entire evolutionary history of associated hosts and parasites. The posterior probability density of the parameters of the model of host switching are evaluated numerically using Markov chain Monte Carlo. In particular, the method generates the probability density of the number of host switches and of the host switching rate. Moreover, the method provides information on the probability that an event of host switching is associated with a particular pair of branches. A Bayesian approach has several advantages over other methods for the analysis of cospeciation. In particular, it does not assume that the host or parasite phylogenies are known without error; many alternative phylogenies are sampled in proportion to their probability of being correct.}, keywords = {animals, Bayes Theorem, dna, host parasite, Lice/physiology, Models, Genetic, Monte Carlo Method, Research Support, U.S. Gov{\textquoteright}t, Non-P.H.S., Research Support, U.S. Gov{\textquoteright}t, P.H.S., Rodentia/parasitology}, isbn = {0014-3820}, author = {Huelsenbeck,J.

Chewing lice, Geomydoecus and Thomomydoecus, coexist on pocket gophers, Thomomys spp. We investigated the spatial distribution of the 2 genera on their hosts and explored possible mechanisms of resource partitioning by chewing lice. Chewing lice appear to partition available host resources spatially, with Geomydoecus occurring primarily on the lateral and dorsal regions of the host, and Thomomydoecus occurring primarily on the lateral and ventral regions. Although spatial partitioning of the host habitat is evident, it does not appear to be explained by hair diameter. Spatial partitioning of the host\&$\#$39;s body could be the result of some other factor, possibly temperature or humidity gradients of the host\&$\#$39;s body.

We examined the relationship between mammalian hair diameter and body mass at several taxonomic levels (interordinal, intrafamilial, intrageneric, and intraspecific) and showed a significant, positive allometric relationship between hair diameter and body size at all taxonomic levels examined. The allometric coefficient (alpha) ranged from 0.13 to 0.33. Within pocket gophers (Geomyidae), a significant positive relationship exists between hair diameter and rostral groove dimensions of their chewing lice, Geomydoecus, which use the rostral groove to grasp hairs of their host. Coupled with previous evidence of a strong allometric relationship between rostral groove width and louse body size, our findings suggest that hair diameter of the host is an important determinant of body size in chewing lice that parasitize pocket gophers.

A total of 4,532 sucking lice belonging to six species, viz. Polyplax gracilis, P. hannswrangeli, P. reclinata, P. serrata, P. spinigera, P, spinulosa were collected from 44,896 examined individuals of 28 small mammal species in Slovakia during 1964- 1999. P. serrata and P. spinulosa occur frequently throughout Slovakia. P. reclinata is relatively rare, occurring more often in lowland areas than mountains. P. spinigera is not common, occurring mainly in the lowlands and mountain basins. The distribution Centre of P. hannswrangeli lies in the Zapadne Tatry, Vysoke Tatry, Belianske Tatry and Nizke Tatry Mts. This louse sometimes occurs in the Popradska kotlina basin, Muranska planina plateau, the Oravske Beskydy, Kysucke Beskydy, Velka Fatra and Oravska Magura Mts at altitudes exceeding 700 m a.s.l., i.e. the 5(th) vegetation tier (fire-beech) and higher. P. gracilis is a very rare species found in Slovakia for the first time.

The same species of sucking louse (Phthiraptera-Anoplura) from the Chilean abrocomid rodent Abrocoma bennetti Waterhouse, 1837 was recently described as Eulinognathus chilensis Gomez, 1998 and as Abrocomaphthirus hoplai Durden \& Webb, 1999. We discuss the nomenclature of this louse and confirm that is correct name is now Abrocomaphthirus chilensis (Gomez, 1998). After comparing type specimens designated from each description, we also document some morphological variation within this species with respect to the paratergal plate on abdominal segment 3 in the female which usually has two relatively long apical setae, but occasionally has only one.
