Abstract

Asymphylodora fishelsoni sp. n. is described from the cyprinodontid fish, Aphanius dispar richardsoni, an endemic subspecies from a brackish water spring flowing into the Dead Sea at Ein Fashkha, Israel. The new species is closest to A. carpiae Szidat, 1943, but differs significantly in being less than half its size, and in having the vesicular pars prostatica in the form of a distinct chamber, the caeca always inflated (rather than narrow), the seminal vesicle entirely postacetabular (rather than overlapping the acetabulum) and occupying 40 – 48% of the cirrus sac length (rather than 80%), the cirrus overlapping the acetabulum (rather than being entirely sinistral to it) and occupying 44 – 50% of the cirrus sac length (rather than 18%), and the anterior part of the terminal organ representing 35 – 54% of the total length of this organ (rather than 22%). Positive allometric growth is shown by the hindbody, posttesticular body, and gonads, whereas the forebody, suckers, and pharynx are negative.
