DESCRIPTION OF ISOSPORA-SCHLEGELI SP-NOV (APICOMPLEXA, EIMERIIDAE) FROM GEKKONID LIZARDS IN THE SOUTH-PACIFIC

A new species of coccidian was recovered from feces of Hemidactylus fr enatus (type host) and Lepidodactylus lugubris from the South Pacific. Oocysts of Isospora schlegeli sp. nov. are subspherical, 17.8 x 15.8 (13.6-20.0 x 12.8-18.0) mu-m; shape index 1.13 (1.06-1.25). Micropyle and oocyst residuum absent, polar granule present. Sporocysts ovoidal, 10.0 x 7.5 (8.8-11.8 x 6.6-9.0) mu-m, with Stieda and substieda bodie s; shape index 1.33 (1.20-1.51). Sporozoites each with anterior and po sterior refractile bodies. In addition, oocysts of Eimeria furmani, Ei meria dixoni, and Isospora frenatus were collected from both the above hosts and an unnamed elongate Eimeria sp. of Yamamoto (K. Yamamoto. 1 933. Fukuoka Igaku Zasshi. 26:40-43) were seen in H. frenatus.
