R. Pineda et al., A NEW SPECIES OF THE GENUS ARGULUS (CRUSTACEA, BRANCHIURA) PARASITIC ON ATRACTOSTEUS-TROPICUS (PISCES, LEPISOSTEIDAE) FROM TABASCO, MEXICO, Systematic parasitology, 30(3), 1995, pp. 199-206
A new species of Argulus is described from the garfish Atractosteus tr
opicus in the Tabasco wetlands, Mexico. Comparisons are made with what
appear to be its closest relatives. This species is characterised by
the presence of two notches in the inner margin of the large respirato
ry area, seven to nine supporting sclerites in the suckers, and the ch
aracteristic shape of the sexual modifications of the second, third an
d fourth legs in the male.
