Three new species of fleas belonging to the genus Macrostylophora (Siphonaptera, Ceratophyllidae) are described from the three-striped ground squirrel, Lariscus insignis, from Tjibodas, West Java (Jawa Barat), Indonesia at an elevation of 1500 m. Macrostylophora larisci sp. n. is described from three male specimens, Macrostylophora debilitata sp. n. is described from one male and Macrostylophora wilsoni sp. n. is described from one female. Non-genital morphological characters of the female specimen, including ctenidial spine shapes and lengths, show that it is not the corresponding female for either M. larisci sp. n. or M. debilitata sp. n. It is unusual for three different species of congeneric fleas to parasitize the same host species in the same geographical location. These three new species represent the first known records of Macrostylophora from Java and they could be enzootic vectors between rodents of flea-borne zoonotic pathogens such as Rickettsia typhi and Yersinia pestis, both of which are established on Java. A list is provided of the 43 known species and 12 subspecies of Macrostylophora together with their known geographical distributions and hosts. A map depicting the distributions of known Indonesian (and Bornean) species of Macrostylophora is also included.
