Clarias (batrachus)(L.)


Stomach, Duodenum


Guwahati (Assam)


Body short, broad and fleshy, 5.61-11.35 mm in length, 2.97-5.28 mm in maximum breadth at level of cirrus sac; body proper divided into an outer cortex and an inner- medulla by two layers of longitudinal muscles. Scolex globular with a terminal sucker. Neck marked off from the body. Testes 155-383 in number, spherical or ovoid, extending in two lateral rows from some distance behind the neck up to the level just in front of the ovary; cirrus pouch not well defined, opening into a common atrium immediately in front of the utero-vaginal pore; genital atrium close to posterior extremity,just in front of the ovarian isthmus. Ovary bilobed, at posterior extremity, follicular, the two lobes joined to each other by an ovarian isthmus; uterus partly glandular, its coils largely in the median field of medulla, and reaching cephalad up to the commencement of testicular region. Vitellaria globular, extending in cortical parenchyma of testicular and ovarian zone; no post-ovarian vitelline follicles present. Eggs 0.056-0.073 x 0.028-0.039 mm, oval, spiny, operculate.Â


The present form is identified to be D. penetrans Bovien, 1926 because it shares with the type species all the salient morphological features like a distinct sucker at the tip of the scolex, neck marked off from the body, no post-ovarian vitelline follicles, cirrus sac not prominent, and spinose eggs.

On comparison with the other known forms, the present form is found to be distinctly different from D. indica Satpute and Agarwal (1980), described from C. batrachus in Raipur (Madhya Pradesh), in not having the post-ovarian vitelline follicles and in the absence of a prominent cirrus sac and receptaculum seminis, though it shares the characters such as the presence of a sucker at the tip of the holdfast and spinose eggs.

The present form also does not fit into the description of the other Indian species of Djombangia, i.e., D. caballeroi Sahay and Sahay (1977). , The latter species, described from Heteropneustes fossilis in Bihar, is reported to have a conspicuous cirrus sac, non-operculate and aspinose eggs, the characters which distinguish it from D. penetrans. Till more material is collected and studied from various localities it appears that the genus Djombangia is represented by three species in India.
