Three new species of fleas belonging to the genus Macrostylophora from the three‐striped ground squirrel, Lariscus insignis, in Java

Abstract

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.

The enemy release hypothesis and Callosciurus erythraeus in Argentina: combining community and biogeographical parasitological studies

“…Regarding the biogeographical analyses, we found partial support to our second working hypothesis (enhanced performance). In accordance to the first 1932;Myers and Kuntz 1964;Hoogstraal and Kohls 1965;Schmidt et al 1967;Durette-Desset 1970;Blagoveshchenskiy 1972;Traub 1972;Kliks and Durette-Desset 1976;Li et al 1976;Chin 1979;Fischthal and Kuntz 1981;Wang 1981;Liu et al 1982;Durden and Musser 1994;Shinozaki et al 2004;Huang et al 2010;Zuo et al 2011;Lurz et al 2013;Durden and Beaucournu 2014). For introduced ranges, we used parasitological studies conducted in: Argentina (this study-section ''Community analyses''-and two previous publications; Gozzi et al 2013Gozzi et al , 2014 prediction, macroparasite richness of C. erythraeus was lower in introduced than in native range, which may contribute to its invasion success (Torchin et al 2003).…”
