Abstract

Two rows of clamps are present on the haptor ofPseudothoracocotyla indica. Each clamp possesses a median sclerite and ten pairs of rib-like sclerites. A pair of edge sclerites occurs on each half of the clamp. The apparent shape and size of the clamps and the number of rib-like sclerites visible varied due to retraction into and extension from muscular depressions. A buccal cavity and pre-oral pit is present. The body surface is ridged and possesses shallow pit-like depressions, although microvilli are absent. Both uniciliated and non-ciliated presumed sensory endings are present on the body surface and haptor. Specimens ofP. indica reattached themselves on the body surface ofPricea multae causing characteristic tegumental damage.
