| larval hannemania sp. infestations of spea spp. in the southern high plains, texas, usa. | we describe a case history of larval hannemania sp. (acari: trombiculidae) infestations in two spadefoot toads (spea spp. anura: pelobatidae) captured from playa wetlands in the southern high plains, texas. hannemania sp. larvae were superficially attached to the skin, not encysted, and dermal changes were not observed. gross field examinations revealed a presumed occurrence of hannemania sp. in spea spp. at four of 24 wetlands in 2003 and 2004. although other species of amphibians were present ... | 2007 | 17984273 |
