Description
Summary:Vexillata geomyos n. sp. is described as a parasite of Attwater's pocket gopher, Geomys attwateri (Geomyidae), from Welder Wildlife Refuge, Texas. The new species possesses 12 cuticular ridges; based on this character, it can be distinguished from 7 of the 13 species in the genus. From the 6 remaining species, V. geomyos can be differentiated because the dorsal ray in 3 of them (V. armandae, V. dessetae, and V. vexillata) has 2 short branches arising from main trunk, whereas dorsal ray of the new species lacks these branches. In addition, V. geomyos can be distinguished from V. brooksi because its spicules are divided at the tip (whereas in the new species, spicules are whole). The new species differs from V. legallae and V. convoluta in the number and arrangement of cuticular ridges at the posterior region of the body.
