FIGURE 6 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 6. Comparative morphology of the segment 1 sternal plate in species of Paracentrophyes and Mixtophyes, visualized with light microscopy (A–C, F, G) and scanning electron microscopy (D–E, H, I). Arrows on light microscope images indicate intracuticular lines, forming partial differentiation of the sternal plates. On the scanning electron micrographs, the arrows show foldings in the cuticle, suggesting the presence of intracuticular lines. Type status and museum catalogue numbers for LM specimens appear in parentheses after each species name. A. Paracentrophyes quadridentatus (non-type, ZMUC KIN-107). B. Paracentrophyes praedictus (allotype, USNM 69988). C. Paracentrophyes anurus (holotype, ZMUC KIN-341). D. P. quadridentatus. E. P. anurus. F. Mixtophyes abyssalis (holotype, ZMB 11516). G. Paracentrophyes sanchezae n. sp. (paratype, ZMUC KIN-1015). H. M. abyssalis. G. P. sanchezae n. sp.
