Abstract

A new Eimeria species is described from a common bronzewing pigeon (Phaps chalcoptera) (Latham, 1790) in Western Australia. Sporulated oocysts of Eimeria chalcoptereae n. sp. (n = 30) are subspheroidal, 22–25 × 21–24 (23.5 × 22.6) μm; length/width (L/W) ratio 1.0–1.1 (1.04) μm. Wall bi-layered, 1.0–1.4 (1.2) μm thick, outer layer smooth, c.2/3 of total thickness. Micropyle barely discernible. Oocyst residuum is absent, but 2 to 3 small polar granules are present. Sporocysts (n = 30) ellipsoidal, 13–14 × 7–8 (13.5 × 7.2) μm; L/W ratio 1.8–2.0 (1.88). Stieda body present, flattened to half-moon-shaped, 0.5 × 2.0 μm; sub-Stieda present, rounded to trapezoidal, 1.5 × 2.5 μm; para-Stieda body absent; sporocyst residuum present, usually as an irregular body consisting of numerous small granules that appear to be membrane-bound. Sporozoites vermiform, with a robust refractile body and centrally located nucleus. Isolated Eimeria oocysts were analysed at the 18S and 28S ribosomal RNA and the mitochondrial cytochrome oxidase (COI) loci. Analyses revealed that Eimeria chalcoptereae n. sp. shared the highest number of molecular features with an Eimeria sp. previously identified from a domestic pigeon in Australia (KT305927-29), with similarities at these three loci of 98.53%, 97.32% and 94.93%, respectively. According to morphological and molecular analysis, the isolated coccidian parasite is a new species of Eimeria named Eimeria chalcoptereae n. sp. after its host, the common bronzewing pigeon (Phaps chalcoptera) (Columbiformes: Columbidae) (Latham, 1790).
