Host genus Hyla Laurenti 1768

(32 spp.)

Eimeria belawini Yakimoff 1930 ( Fig. 10) Type host: Hyla arborea (L. 1758), European treefrog.

Other hosts: None reported to date.

Type locality: CAUCASIA.

Geographic distribution: CAUCASIA.

Description of sporulated oocyst: Oocyst shape: spheroidal; number of walls: 1 (from line drawing); wall thickness and characteristics: unknown; L: 12; L/W ratio: 1.0; M, OR, PG: all absent (line drawing). Distinctive features of oocyst: none.

Description of sporocyst and sporozoites: Sporocyst shape: spheroidal; L x W: 4 x 4; L/W ratio: 1.0; SB, SSB, PSB and SR: all absent (line drawing); SZ: unknown. Distinctive features of sporocyst: none.

Prevalence: Unknown.

Sporulation: Unknown.

Prepatent and patent periods: Unknown.

Site of infection: Unknown.

Endogenous stages: Unknown.

Pathology: Unknown.

Materials deposited: None.

Remarks: This is the only Eimeria species described from a treefrog of the genus Hyla . Because most amphibian eimerians do not cross generic boundaries we feel that Yakimoff’s (1930a, b) species is valid, but poorly described.

Isospora wladimirovi Yakimoff 1930a ( Fig. 11)

Type host: Hyla arborea (L. 1758), European treefrog.

Other hosts: None reported to date.

Type locality: CAUCASIA.

Geographic distribution: CAUCASIA.

Description of sporulated oocyst: Oocyst shape: ovoidal to ellipsoidal; number of walls: 1 (line drawing); wall thickness and characteristics: unknown; L x W: 21.4 x 17.6 (18–25 x 15–21); L/W ratio: 1.2; M, OR, PG: all absent (line drawing). Distinctive features of oocyst: none.

Description of sporocyst and sporozoites: Sporocyst shape: subspheroidal; L x W: 13 x 9; L/W ratio: 1.4; SB, SSB, PSB: all absent (line drawing); SR; present; distinct (line drawing); SZ: elongate 8.9 x 4.4. Distinctive features of sporocyst: none.

Prevalence: Unknown.

Sporulation: Unknown, but Yakimoff (1930a) reported finding oocysts in a sporulated state in the intestinal content.

Prepatent and patent periods: Unknown.

Site of infection: Unknown.

Endogenous stages: Unknown.

Pathology: Unknown.

Materials deposited: None.

Remarks: This is the only Isospora species described from a treefrog of the genus Hyla . Because most amphibian isosporans probably do not cross generic boundaries, we feel that Yakimoff’s (1930a, b) species is valid, but poorly described.
