Treatment

Material examined. Reference material. The holotype ( SMNH Type 8907) and 4 whole mounts and 4 serially sectioned specimens from Lanzarote (HU VII.4.45–VIII.1.02) .

Known distribution. Lanzarote, Canary Islands, Spain ( Gobert et al. 2017).

Remarks. The caudal region of Cheliplana sarnensis is very extensible, similar to the situation in C. varicauda . As such, the overall body length depends on the state of contraction. The proboscis is provided with a pair of curved, 13–20-µm-long proboscis hooks, without denticles. The hook supports are small, only 7 μm long. The male genital apparatus has a single functional seminal vesicle. The copulatory bulb contains a proximal prostate vesicle and, more distally, an ~84-µm-long sclerotised ejaculatory duct. The distal part of the ejaculatory duct is transformed in a ~42-µm-long cirrus armed with very fine spines of uniform length. The vagina externa and bursa are connected to the ovary through three intertwined, funnel-shaped, sclerotised spermatic ducts.
