Additional occurrence of the filarioid nematode, Litomosoides westi, in Geomys spp. in Texas.
Specimens of G. breviceps and G. bursarius examined during this study are deposited in the Sternberg Museum of Natural History (MHP) at Fort Hays State University. Specimens of L. westi from host gophers were stored in vials with glycerin and are deposited as voucher specimens (97-P7) in the Laboratory of Parasitology, Department of Wildlife and Fisheries Sciences at Texas A & M University.
While collecting Geomys breviceps and G. bursarius in Denton County, Texas nematodes identified as L. westi were collected from the pleural cavities of an adult male (MHP 33365) and an adult female (MHP 33366) G. breviceps, at the entrance of Isle Du Boris Unit, Lake Ray Roberts State Park. Additional L. westi were found in the pleural cavities of three adult G. bursarius, two males (MHP 33444, 33445) and one female (MHP 33457) 1.6 mi NW of Aubrey, Grubbs Road. The pocket gophers were captured using Victor gopher traps. The dead pocket gophers were immediately necropsied, to obtain tissue samples for karyotyping. The filarioid nematodes were collected from the pleural cavities using forceps. They were placed in vials with 70% ethanol. The vials were labeled with the host field catalogue number and shipped to Texas A & M University for identification. The filarioid nematodes were identical to those described by West (1962). This is the first record of L. westi from G. breviceps and the first reported occurrence of L. westi from G. bursarius in Texas. These records also fill in the range gap from southern Texas to the southern foothills of Colorado for L. westi.
