Cheliplana spuriaseminalis Diez, Reygel & Artois, 2019

Material examined. None.

Known distribution. Bueycabón, Cuba (Diez et al. 2019).

Remarks (summarised from literature). Specimens are pinkish and have a body length of 0.9–1 mm when whole mounted. The proboscis is armed with 16-µm-long, curved hooks. The muscular hook supports measure 5 µm. The spiny prepharyngeal cavity is twice as long as the pharynx.

A single testis lies caudally to the pharynx. Seminal vesicles are paired and empty proximally into the copulatory bulb. Only one seminal vesicle is functional and filled with sperm, the other one is atrophied, empty and not connected to the testis. The cylindrical, curved copulatory bulb (83–105 µm x 14–17 µm) comprises the prostate vesicle, one or more accessory glands and a 31-µm-long, unarmed cirrus. Distally, the cirrus widens and is surrounded by longitudinal muscles.

The single ovary and bursa are positioned caudally to copulatory bulb. The bursa is connected to the common atrium and opens to the outside world through a vagina externa. The gonopore lies anterior to the vaginal opening.
