FIGURE 3 in Description of a new kinorhynch species, Paracentrophyes sanchezae n. sp. (Kinorhyncha: Allomalorhagida) from the Gulf of Mexico, with differential notes on one additional, yet undescribed species of the genus
FIGURE 3. Diagram of mouth cone (grey area), introvert and placids in Paracentrophyes sanchezae n. sp., showing distribution of outer oral styles, spinoscalids, trichoscalids and placids. The table below shows the scalid arrangement by sector (S1 to S10), and summarized scalid numbers by rings and sectors. Question marks indicate that the occurrences of eventual inner oral styles are uncertain; some scalids could not be observed, but their expected positions inferred from the usual introvert symmetry patterns are indicated in grey tone.
