Cheliplana textilis Jouk & De Vocht, 1989

Material examined. Reference material. 1 whole mount (the holotype) ( SMNH Type 6982) and 3 serially sectioned specimens (paratypes) (HU 149–151) from Kenya .

Known distribution. Mombasa, Kenya ( Jouk & De Vocht 1989).

Remarks. Our measurements and observations are consistent with those of Jouk and De Vocht (1989). The specimens are small, between 0.3 and 0.5 mm. A single caudal haptic girdle is observed. Jouk and De Vocht (1989) do not mention the colouration in live specimens. The mouth connects to the cylindrical pharynx via a long, unpaired prepharyngeal cavity. The proboscis has an overall length of ~20 μm and has small hook supports (~6 μm), armed with slender, smooth hooks measuring 16 μm. The proboscis sidepieces are soft, but bear small, sclerotised needles.

A single testis is present near the posterior end of the pharynx. The male copulatory organ lies in the caudal third of the body. A pair of seminal vesicles and a pair of strands of prostatic glands empty into the bulb. The prostatic glands surround the ejaculatory duct, which leads to the ejaculatory cirrus. The latter is ~30 μm long and accompanied by a pair of accessory cirri, each measuring ~40 μm. The ejaculatory cirrus and the accessory cirri are armed with small spines. The accessory cirri are armed on one side only.
