features
The elongated body of Chtonobdella limbata is colored bottle green and marked in the middle of the back with a distinct yellow longitudinal stripe and with yellowish lateral longitudinal stripes, on the side of the back dense and irregularly spotted black and also spotted black on the belly. The animal becomes 3 cm to 5 cm long and 4 mm to 10 mm wide. The rear suction cup has a diameter of about 10 mm. The middle segments each have 5 ringlets, the whole animal has about 89 to 95 ringlets and has clear transverse rows of papillae. The back is grainy on the rear suction cup. The male genital opening is between the 30th and 31st, the female between the 37th and 38th segment. On other specimens, the genital openings are between the 24th and 25th and the 31st and 32nd segments. Chtonobdella limbata has two ventrolateral jaws with 67 pointed teeth each, but like other Chtonobdella species does not have a central dorsal jaw, as found in the Haemadipsa genus common leeches in Southeast Asia . The bite wounds therefore only have two punctures and not three as with Haemadipsa .
