The description of a new driftwood catfish has been published in a recent issue of the journal Neotropical Ichthyology.
Carla Pavanelli and Alessandro Bifi name Tatia jaracatia from the lower Iguau River drainage, and distinguish it from congeners in having large pale, irregular blotches over a dark brown body, caudal fin uniformly dark brown or with few irregular dark brown blotches, the anal-fin rays of mature males uniformly decreasing in size from the third unbranched ray, 31"32 post-Weberian vertebrae, 9"10 ribs, 3"5 haemal spines, and the humeral process reaching or surpassing the vertical line through the origin of the dorsal fin.
The species is named after its type locality, the Jaracati River in the lower Iguau River drainage.
