FIGURE 1. Micrographs of Fridericia ventrochaetosa sp. n. A. Brain (DNA 1109). B. Brain (holotype). C. Epidermal glands. D. Thick body wall and cuticle (marked with arrow). E. Strong septa, 5/6– 9/10 (holotype). F–G. Head region (the thick epithelium of prostomium marked with arrow). H. Clitellar glands, lateral view. I.
