- Title
Morphology and ultrastructure of the sensory appendages of a kinorhynch introvert.

- Abstract
The structure and arrangement of appendages (scalids) on the head of the homalorhagid kinorhynch Kinorhynchus phyllotropis Brown & Higgins, 1983 are named, described and illustrated. In adults of this species, seven rings of external scalids are separated by segment boundary structures from the oral styles and three rings of internal scalids. All of these appendages contain ciliated receptor cells which pass to pores at the scalid tips, and all but the two anterior rings are jointed. All of these appendages are radially arranged in multiples of five, and closely associated with the ten lobed circumoral nerve ring. The most posterior scalid ring consists of fourteen trichoscalids, of which six are longer than the other eight. The six longer trichoscalids are arranged in bilateral symmetry, two to each of the three facets of the body. Similarities between scalid arrangement in Kinorhyncha and Loricifera are discussed.
