specimen (before sectioning) matches perfectly our observations in that the ‘body is pale chestnut in colour on the dorsal side except only the portion of the neck which is whitish; the ventral surface is white’. Other features such as the absence of eyes and the unique arrangement of the proboscis muscle layers in relation to the nerve plexus (outer longitudinal, nerve plexus, inner longitudinal, and inner circular muscle layers) add more credence to the species identification of our specimens.
