Abstract
    Phyllodiaptomus wellekensae n. sp. is described from south India. In the female, the genital somite is dilated at the left proximal margin and armed with an extraordinarily large, somewhat curved, laterally-directed spine; the right genital spine is much smaller than the left one. The terminal claw of leg 5 has a secretory pore at its tip and a characteristic conveyor canal on its anterior surface. In the right male P5, the coxal plate is short and unique in shape. The basis is 1.3 times as long as wide, with a long, sinuous, hyaline lamella on its medial margin. The first exopodite segment is short and optuse at its outer distal corner. The second segment is rectangular and has a short, hyaline, spinous projection between the lateral spine and the terminal claw. The left P5 has a large, serrate, hyaline fan between its apical thumb and medial apical seta.P. tunguidus is redescribed based on material newly collected from three localities in China.Scanning electron micrographs are provided for the above two species and also for P. blanci (the type species of the genus) and P. annae. The taxonomic significance of a set of new characters observed in the four species is discussed, and the generic definition is expanded accordingly. The biogeography of Phyllodiaptomus is commented upon.
