Chewing lice (Phthiraptera: Trichodectidae) and the pocket gophers (Rodentia: Geomyidae) that they inhabit have shared an intimate his- torical association that has made them a textbook study for cophylogeny. Herein, we examine the chewing lice found on pocket gophers of the Cratogeomys fumosus species group using DNA sequence data from the mitochondrial cytochrome c oxidase subunit I gene to determine relationships among lice for comparison to published host phylogeny. Although matrix approaches indicate a correlation between host and parasite genetic distances, cophylogenetic reconstruction methods fail to detect a pattern of widespread cophylogeny. In conclusion, this study provides an exception to the rule of host-parasite cophylogeny that could be the result of the young age of the relationships considered herein and the complex history of the Trans-Mexican Volcanic Belt.
Los piojos masticadores (Phthiraptera: Trichodectidae) y las tuzas (Rodentia: Geomyidae) que habitan, han compartido una asociaci\ón hist\órica \íntima que los ha convertido en un estudio de libro de texto para la cofilogenia. En el presente estudio, examinamos los piojos mas- ticadores que se encuentran en las tuzas del grupo de especies de Cratogeomys fumosus utilizando los datos de secuencias de ADN del gen mitocondrial Citocromo C Oxidasa subunidad I para determinar las relaciones entre los piojos en comparaci\ón con la filogenia publicada del hospedero. Si bien los enfoques matriciales indican una correlaci\ón entre las distancias gen\éticas del hospedero y el par\ásito, los m\étodos de reconstrucci\ón cofilogen\éticos no detectan un patr\ón de cofilogenia generalizada. En conclusi\ón, este estudio, proporciona una excepci\ón a la regla de cofilogenia par\ásito-hospedero que podr\ía ser el resultado de la corta edad de las relaciones consideradas en este documento y la compleja historia del Cintur\ón Volc\ánico Trans-Mexicano.
