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.

Molecular data can also help discriminate between competing reconstructions of the history of the host-parasite association. Methods for comparing sequence divergence in hosts and parasites are described and applied to data for pocket gophers and their chewing lice. The hypothesis of cospeciation between these two clades is strongly supported. The lengths of homologous branches in the gopher and louse phylogenies are positively correlated, but there is little support for the hypothesis that lice are evolving an order of magnitude faster than are their hosts.

When life-history traits show evidence for correlated evolutionary change with each other or with ecological differences, it is often possible to single out the trade-offs and selective forces responsible for the evolution of life-history diversity. Suites of life-history characters often evolve in concert, and recent optimality models incorporating few variables show promise for interpreting that evolution in terms of few selective forces. Because hosts provide well-defined environments for their parasites, when host-parasite phylogenies are congruent it is possible to test ideas about the evolution of particular life-history and size-related traits.10abird10abody10acoevolution10acomplex10afood habits10aGeomyidae10aMallophaga10amammal10areproduction10arodentia10asize10athomomys10atrichodectidae1 aHarvey, P., H.1 aKeymer, A., E. uhttps://phthiraptera.myspecies.info/content/comparing-life-histories-using-phylogenies01648nas a2200193 4500008004100000245017100041210006900212260000900281300001400290490000700304520097000311653001601281653000901297653000801306653001301314100002701327700002101354856007901375 1989 eng d00aGeomydoecus thomomyus complex (Mallophaga: Trichodectidae) from pocket gophers of the Thomomys talpoides complex (Rodentia: Geomyidae) of the United States and Canada0 aGeomydoecus thomomyus complex Mallophaga Trichodectidae from poc c1989 a286 - 2970 v823 aEight species o f Geomydoecus from pocket gophers of the Thomomys talpoides complex are described and illustrated: G . thomomyus (McGregor) from 24 T. talpoides sspp. (type host , T. t. rostralis Hall and Montague); G. craigi n. sp. from T. monticola J.
