Synopsis.Oocysts ofEimeria malabaricassp. n. andEimeria bandipurensisfrom the South Indian tree squirrelFunambulus tristriatuscollected in Kerala, India, are described. Sporulated oocysts ofE. malabaricaswere ellipsoid to subspherical measuring 39.8 (35–45) × 32.1 (29–37) m̈m, with a thick (2.5–3.0 m̈m), 2‐layered wall. The outer layer was yellow‐brown, striated, and rough. There was no micropyle. but a polar granule was present in 34% of oocysts. The sporocysts were ovoid, 16.0 (14.0–18.0) × 11.2 (11.0–12.0) m̈m, with a Stieda body and a granular residuum. Excysted sporozoites were 21.8 (19.0–23.0) × 3.4 (3.0–4.0) m̈m, with a large refractile body.The sporulated oocysts ofE. band
