Ischnopsyllus (Hexactenopsylla) indicus Jordan, 1931

Material examined.

Philippines, Negros Island, Mt. Bungal, Northern Negros Natural Park (10.674°N, 123.189°E), elev. 1200m, Pipistrellus javanicus (Gray) (JAE3252), 23 VII 2009, J. Esselstyn, (1♂).

Remarks.

Ischnopsyllus indicus has been documented in China, Taiwan, Vietnam, India, Guam, Sri Lanka, and Japan from a number of vespertilionid bat species; however, this is the first record of Ischnopsyllus indicus in the Philippines. Finding this flea in the Philippines is no surprise, since Ischnopsyllus indicus was documented in Guam by Jordan (1941), in Japan by Hopkins and Rothschild (1956), and is very common in Japan according to Sakaguti and Jameson (1962) on the same host species ( Pipistrellus javanicus ) on which we found this species. Pipistrellus javanicus is widely distributed in eastern Russia, China, south and central Japan, Southeast Asia through the Sunda Islands, and in the Philippines ( Wilson and Reeder 2005). Several differences should be noted in our specimen and those illustrated in the original male description by Jordan (1941) and subsequently copied by Hopkins and Rothschild (1956). The telomere appears more oblique at its apex. There are a pair of flat ribbon-like, long curved setae at the apex (one pair on each side) of S-VIII. This does not appear illustrated as such by either Jordan or Hopkins and Rothschild. These ribbon-like setae are absent in all other species of the subgenus Hexactenopsylla . The illustrations of Sakaguti and Jameson (1962) more accurately depict the features of our single male from Luzon.
