Rhynchoclevelandella sp. 2

( Fig. 21A–C, G–I ; Supporting Information, Table S23) Rhynchoclevelandella sp. 2 was detected and morphologically characterized in a single host population (ASS), with a very low abundance—no more than 10 individuals in a single host.

Rhynchoclenelandella sp. 2 is morphologically very similar to R. nipponensis , albeit a bit smaller: 73 (excluding one unusually large individual) vs. 82 µm in vivo and 56 vs. 65 µm in protargol preparations with larger micronucleus (7 × 4.8 vs. 5.5 × 3 µm). A single gargantuan cell (146 × 58 µm) was seen ( Fig. 21A ) and molecularly characterized.
