A brief survey is given of our past and present knowledge of the distribution of pocket gophers and their only mallophagan parasites (Trichodectes: Geomydoecus). Emphasis is then placed on the lice found on the Thomomys bottae-umbrinus gopher complex of the western and southwestern United States and northern Mexico. Recent extensive collections of Geomydoecus from over 90 of the 200-plus subspecies of these hosts have resulted in interesting geographical delineations of eight species of Geomydoecus, these not necessarily following what might be anticipated from the present host classification.

A study of 1st-instar nymphs representing 119 of the 122 currently recognized taxa of pocket gopher lice of the genera Geomydoecus and Thomomydoecus resulted in the recognition of numerous valuable taxonomic features enabling reliable differentiation for a surprisingly large number of these lice. These characters are discussed primarily at the species complex level, with mention of specific differences where pertinent. A key is given for the identification of the currently recognized 26 complexes of pocket gopher lice.

One of the greatest challenges in mammalian systematics is the Thomomys bottae-umbrinus complex, with its approximately 225 described subspecies. As part of a taxonomic investigation of the lice from these gophers we have accumulated and mounted over 31,000 adult lice from 2,000 hosts representing over 1,000 localities, and have quantified over 300,000 character observations from more than 11,000 of these lice. These character observations combined with their host and locality information form a computerized data base which is maintained at the University of Minnesota. Because of the quantity and complexity of these data we have automated our data handling and analysis and some portions of the taxonomic decision making process. We have developed an integrated group of computer p r og rams called the BUG system which is used for the retrieval and analysis of stored louse data. This system provides for the definition of tentative taxonomic louse groups, the extraction of data for lice within these groups, and the analysis or comparison of these data within a group or between groups. Group definitions may be based on preliminary louse identification, host identification, host locality specific host, or specific louse, or any combination of these criteria. The kinds of analyses built into the system include general data summarization, character correlations, analysis of variance, principal components analysis, and agglomerative clustering. The system also has some graphics capabilities,including character distribution graphs, principal components scattergrams, and host geographic distribution maps. It can also select and format- louse data for use with general statistical analysis computer program packages such as the BMD-Biomedical Computer Programs. The system is used to evaluate character homogeneity within groups of lice, make comparisons between groups and identify taxonomically useful characters for descriptions. Criteria for taxonomic groupings were developed from a comprehensive study of louse variation using a 5-level nested analysis of variance model. We have delineated 25 new louse taxa so far during this study and it is likely that more will be found.

Hybridization between the pocket gophers Thomomys bottae and T. townsendii at Cold Run Creek in Honey Lake Valley, Lassen County, California, is examined by electromorphic and morphologic characters and by the distribution of ectoparasitic mallophagan lice. Hybrid formation is minimal (about 12\% of the total sample of 104 individuals examined), but both F1 hybrids and a few presumptive backcross individuals are apparent. Nevertheless, no evidence of genic introgression based on five diagnostic allozyme loci is present in parental populations of either taxon within a mile of the hybrid zone. Similarly, louse species unique to each parental gopher host do not penetrate beyond the geographic limits of the genetic hybrid zone into the range of the opposite gopher species. A narrow zone of hvbridization is thus concordantly defined by genetic, morphologic, and ectoparasitic parameters. These two gopher taxa are thus genetically if not reproductively isolated and should be considered separate biological species.

A computerized taxonomic and geographic storage, retrieval, analysis, and distribution mapping system was used to evaluate 51,670 specimens of Geomydoecus and Thomomydoecus chewing lice collected from 226 species and subspecies of the pocket gophers Thomomys bottae, T. umbrinus, T. townsendii, and T. bulbiuorus. These lice consisted of 52 species and subspecies in 8 complexes. Comparison of the geographic ranges of louse complexes with those of associated host taxa showed that, while most host taxa had a fairly uniform louse fauna, 70 subspecies possessed geographically separated localities with 2 or more louse taxa from the same genus. The distribution of louse complexes corresponded reasonably well to pocket gopher species but showed a somewhat different separation between T. bottae and T. umbrinus than that presently defined by gopher taxonomists. Comparison of geographically isolated host populations based on louse associations showed both similarities to and differences from that based on allozymal similarity among the hosts, with the louse-based groups geographically well defined. Individual hosts rarely harbored more than 1 louse species per genus, and in 1 case where this occurred the host was found to be an F, hybrid of parental taxa that were each associated with 1 of the louse species.

Sixteen species and subspecies of the Geomydoecus californicus complex are described and illustrated: G. californicus from 14 subspecies of Thomomys bottae (type-host: T. b. bottae); G. centralis, n. sp. from 59 subspecies of T. bottae and 1 of T. umbrinus (type-host: T. b. centralis); G. albati, n. sp. from 4 subspecies of T. bottae (type-host: T. b. albatus); G. angularis, n. sp. from 9 subspecies of T. bottae (type-host: T. b. angularis); G. bajaiensis, n. sp. from 16 subspecies of T. bottae (type-host: T . b. abbotti); G. clausonae, n. sp. from 2 subspecies of T. bottae (type-host: T. b. anitae); G. limitaris limitaris, n. sp, from 9 sub-species of T. bottae (type-host: T. b. limitaris); G. l. bakeri, n. subsp. from 7 subspecies of T. bottae and 1 of T. umbrinus (type-host: T. b. fulvus); G. l. halli, n. subsp. from 3 subspecies of T . bottae (type-host: T. b. proximus); G. l. tolteci, n. subsp. from 5 subspecies of T. bottae (type-host: T. b. toltecus): G. aurei aurei, n. sp. from 9 subspecies of T. bottae (type-host: T. b. aureus); G. a. grahamensis, n. subsp. from 6 subspecies of T. bottae and 1 of T. umbrinus (type-host: T. b. grahamensis); G. actuosi, n. sp. from 13 subspecies of T. bottae (type-host: T. b. actuosus); G. sinalone, n. sp. from 2 subspecies of T. bottae (type-host: T. b. sinalone); G. crovelloi, n. sp. from 2 subspecies of T. umbrinus (type-host: T. u. sonoriensis); and G. warmanne, n sp. from 1 subspecies of T. bottae and 13 of T. umbrinus (type-host: T. u. madrensis). Distinctions among taxa are shown using qualitative and quantitative characters. Discriminant functions for 2 or 3 characters are provided in instances where they are shown to offer enhanced differentiation over single characters. A key is provided for the identification of these 16 taxa.

Two subgenera of Geomydoecus are recognised - the nominate subgenus for 42 previously recognised taxa and Thomomydoecus, n. subgen., for 6 taxa, including 3 new species herein described. The new species and their type-hosts are G. (T.) jamesbeeri from Thomomys umbrinus supernus, G. (T.) genowaysi from T. u. madrensis, and G. (T.) dickermani from T. u. tolucae.
