Isospora attilae Rodrigues, Silva, Lopes, Berto, Luz, Ferreira & Lopes, 2015, n. sp

Isospora attilae n. sp. Type host. Grey-hooded attila Attila rufus (Vieillot, 1819) (Aves: Passeriformes: Tyrannidae). Type locality. Marambaia Island (23 ��04'S, 43 �� 53 'W), Rio de Janeiro, Brazil. Site of infection. Not investigated Type-material. Oocysts in 70���100 % ethanol, phototypes and line drawings are deposited and available (http:// r 1.ufrrj.br/lcc) in the Parasitology Collection of the Laborat��rio de Cocc��dios e Coccidioses, at UFRRJ, located in Serop��dica, Rio de Janeiro, Brazil. Photographs of the type-host specimens (symbiotypes) are deposited in the same collection. The repository number is P- 57 / 2015. Etymology. The specific epithet is derived from the generic name of the type host. Description (Figs 1 a���c; 2 a���c). Oocyst shape (n = 17) sub-spherical to ellipsoidal; oocyst wall bilayered; wall thickness 1.3 (1.1���1.5); outer wall smooth, c. 2 / 3 of total thickness; L �� W = 20.3 �� 19.0 (18���22 �� 18���21), L/W ratio = 1.07 (1.0��� 1.2); M, and OR absent, PG present, one or two. Sporocyst shape (n = 13) ellipsoidal; L �� W = 13.5 �� 7.9 (12��� 15 �� 7���9); L/W ratio = 1.73 (1.6���1.9); SB present, knob-like, 1.0 high �� 2.0 wide; SSB present, rounded to trapezoidal, 2.5 high �� 4.0 wide; PSB absent; SR present, composed of granules of different sizes; SZ vermiform with 1 posterior SRB and centrally located N. Remarks. Isospora attilae differs from other Isospora species from the passerines of same family (Table 1). Isospora mionectesi has oocysts and sporocysts larger than I. attilae. Isospora feroxis is very similar to I. attilae, however, it can be distinguished by SB flattened and ovoidal shape of sporocyst (Berto et al., 2009 a; Berto et. al. 2009 b).
