Geomydoecus nebrathkensis Timm and Price


Geomydoecus nebrathkensis Timm and Price  

Type host: Geomys bursarius lutescens Merriam   from Lincoln Co., Nebraska.

Deposition, host records, and locality: HWML 92016, G. lutescens   /Ackley 2013; HWML 92035, G. lutescens   /Ackley 2013; HWML 101756, G. lutescens   /Ackley 2013; HWML 92047, G. lutescens   /Ackley 2013; HWML 92054, G. lutescens   /Ackley 2013.

Remarks: Chewing lice are permanent ectoparasites, passing their entire life cycle on the body of the host. Lice of the genus Geomydoecus   are exclusively associated with pocket gophers, and are strongly host species specific. Geomydoecus nebrathkensis   is easily separated from closely related Geomydoecus oklahomensis Price and Emerson, 1971   , to the south, by the lack of a distinct antennal thumb in the male, and from Geomydoecus geomydis (Osborn, 1891)   , to the east, by general size characters ( Timm and Price 1980). These ectoparasites are generally abundant on the host gopher, with all stages (adults, nymphs, and eggs) infesting the pelage of the host.
