Description
Cheliplana subproximalis Diez, Reygel & Artois, 2019
Material examined. None.
Known distribution. Bueycabón and Las Sardinas, Cuba (Diez et al. 2019).
Remarks (summarised from literature). Live specimens are pinkish, translucent and rather small: The body length is 0.4–0.7 mm, as measured on whole mounts. The proboscis is armed with 13–18-µm-long, curved hooks. The muscular hook supports measure 5–8 µm. The pharynx measures 1/7 to 1/8 of the total body length in live specimens. The spiny prepharyngeal cavity is elongated, measuring twice as long as the pharynx. The mouth opens antero-ventrally and subterminally.
The single testis lies postero-laterally to the pharynx and connects to paired seminal vesicles. Distally, the two seminal vesicles fuse into a short, seminal duct, which opens into the copulatory bulb. Two proximal ducts of unknown origin enter the prostate vesicle near the entrance of the seminal duct. The 62–66-µm-long cirrus is armed with fine spines. Distally, the cirrus is slightly widened and surrounded by an asymmetric sclerotised cap (10–20 µm x 6–10 µm). Cirrus spines measure 2–3 µm in this region.
The vitellarium extends from the pharynx to the copulatory bulb. A single, kidney-shaped ovary is present. Oocytes occur in a row and proximally decrease in diameter. The bursa lies caudally from the common gonopore.
