Cheliplana gibarenha
Diez, Reygel & Artois, 2019
Material examined
. None.
Known distribution.
Gibara,
Cuba
(
Diez
et al.
2019
).
Remarks (summarised from literature)
.Whole-mounted specimens are ~
0.8 mm
long.The body is transparent. The proboscis has a pair of muscular hook supports (
5 µm
) and 14-µm-long, curved hooks. The mouth opens just caudally from the postrostral bulb. The pharynx is slightly shorter than the spiny prepharyngeal cavity.
The single testis lies next to the pharynx and is connected to a single, caudally positioned seminal vesicle (
184 µm
x
28 µm
) through a very long vas deferens. The copulatory bulb is directed forward and comprises an elongate prostate vesicle and the cirrus (
140 µm
x
4 µm
). The distal
13 µm
of the cirrus is armed with small spines (
0.5 µm
). The distal part of the copulatory bulb is characterised by a strong sphincter surrounding the cirrus.
The single ovary is positioned near the transition between the seminal vesicle and prostate vesicle. Oocytes lie in a row and proximally decrease in diameter. The caudally positioned bursa appears bipartite and opens caudally into the vagina.
