摘要

Caecincola aubergina n. sp. is described from white crappie (Pomoxis annularis) from B. A. Steinhagen Reservoir in southeastern Texas, U.S.A. Members of C. aubergina n. sp. have an elongate body (5.5-8.8:1 length:width ratio), a multilobed ovary, large vitelline follicles primarily in the hindbody but extending into the forebody, and an oral sucker that is wider than long. The elongate form of the new specimens distinguishes them from all other species in the genus except Caecincola longiscens and Caecincola cookorum. In the former species, vitelline follicles are confined to the hindbody; in the latter species, the body is peanut-shaped and the vitelline follicles are almost entirely in the forebody. This is the eighth species of Caecincola, and a dichotomous key to the species is presented as well.
