Abstract:
Variations have been observed in the specimens of Pallisentis magnum Saeed and Bilqees, 1971 reported earlier, as having 28-30 proboscis spines measuring 0.28 - 0.32 by 0.16 - 0.20. Surface electron microscopy revealed that the proboscis spines are 32 instead of 28-30 and all are curved ventrally with pointed ends having prominent basal swellings. The spines are of unequal size and are arranged in four rows.
