Abstract

<i>Cheliplana santiaguera</i> Diez, Reygel &amp; Artois, 2019 <b>Material examined.</b> None. <b>Known distribution</b>. Siboney, Cuba (Diez <i>et al.</i> 2019). <b>Remarks (summarised from literature)</b>. Specimens are pinkish and are 0.7–0.8mm long when whole mounted. The proboscis carries 16-µm-long, curved hooks. Hook supports are 6 to 8 µm long. The pharynx measures 124- 126 µm, corresponding to 1/8 of the total body length, and connects to the mouth through a twice as long, spiny prepharyngeal cavity. The copulatory bulb is inverted-pear shaped (50–74 µm) and comprises the prostate vesicle and spiny cirrus (22–28 µm, spines 0.5 µm). A sphincter occurs in the middle of the ejaculatory duct. The vitellarium extends from the pharynx to the copulatory bulb. A single bursa and ovary occur caudally. Oocytes lie in a row and proximally diminish in diameter. The bursa is connected to the common atrium and opens externally through a vagina, posterior to the common gonopore.
