Distinctive feature of oocyst: 3 conical projections (2.1–3.5 long) present on 1 end, with the oocyst wall forming a broadly pointed end on the opposite pole.</p> <p>Description of sporocyst and sporozoites: SP: (n - 4); shape: elongate–ellipsoidal, with a smooth single-layered wall; L x W: 13.7 x 7.5 (12–19 x 6–12), L/W 1.8 (1.7–2.2); SR: sporocyst residuum, coarsely granular, and scattered; SZ: banana-shaped, 14.2 x 3.6 (14–15 x 3–4) in situ; N visible, slightly posterior to midpoint of SZ. Distinctive feature of SP: slightly pointed at 1 end with a distinct SB, SR of only a few globules, and a SRB in each SZ.</p> <p>Taxonomic summary</p> <p>Type host: Central American river turtle, Dermatemys mawii Gray, 1847 (Testudines: Dermatemydidae). Collected 11 August and 11 November 2018. Host photovouchers: University of Florida (UF) 191862-191866.</p> <p>Type and only locality: Belize Foundation for Research and Environmental Education, Mile Marker 58, Southern Highway, Belize, Central America (16 ° 33.326 ' N, 88 ° 42.423 ' W).</p> <p>Prevalence: 1/3 (33%) based on oocyst identification in samples; 3/3 (100%) based on PCR and sequencing of the 18S rRNA and ITS genes.</p> <p>Materials deposited: Photosyntype of a sporulated oocyst is deposited in the Harold W. Manter Laboratory of Parasitology (HWML), University of Nebraska, as HWML 206401.</p> <p>ZooBank registration: urn:lsid:zoobank.org:act:B7C62C80- DF94-49F0-A73F-586C1FB2B578.</p> <p>Etymology: The specific epithet is named in honor of the British naturalist, John Edward Gray (1800–1875), who described the host in 1847.</p> <p>Molecular biology: All 3 fecal samples had similar content of the 18S rRNA and ITS genes. After primer editing, a 347-bp segment of the 18S rRNA gene was determined for the hicatee coccidian (GenBank accession MW538581). BLASTn results identified 99.4% sequence identity to several apicomplexan organisms, including Caryospora -like sp. US3 (MN450817) from a green sea turtle (Chelonia mydas), Caryospora cheloniae genotype 1 (KT361639) from Ch. mydas, and multiple lizard Schellackia spp. The hicatee coccidian was 99.7% identical to a 347-bp segment of the 18S rRNA gene of the reference sample of E. mitraria (GenBank accession MW538549). An 841-bp segment of the ITS region was determined for the hicatee coccidian and reference sample of E. mitraria (GenBank accessions MW538550 and MW538533, respectively), with 75.2% sequence identity to each other. Bayesian phylogenetic analysis placed the hicatee coccidian in a clade with Eimeria collieie, E. mitraria, Eimeria arnyi, and 2 coccidians of green sea turtles (Ca. cheloniae and Caryospora-like sp. US3) with a posterior probability of 0.89 (Fig. 6).</p> <p>Remarks</p> <p>The oocysts being passed by the hicatee possessed multiple conical projections with 3 projecting from 1 pole and a broaderbased projection from the opposite pole (Figs. 2–5). To date, the 7 previously described oocysts of Testudines having mitra-like conical projections or irregular surfaces from at least 1 end of their oocyst are (1) Eimeria amazonensis from the red-footed tortoise, Chelonoidis (formerly Geochelone) carbonaria from Brazil (Lainson et al., 2008); (2) Eimeria hynekprokopi from the Indochinese box turtle, Cuora galbinifrons from Vietnam (Široký and Modrý, 2010); (3) Eimeria iversoni from a captive Galapagos tortoise, Chelonoidis sp. (McAllister et al., 2014); (4) Eimeria jirkamoraveci in the Neotropical chelid turtle Mesoclemmys (previously Batrachemys) heliostemma (Široký et al., 2006); (5) E. mitraria originally described from the Asian Chinese threekeeled pond turtle, Mauremys (formerly Chinemys) reevesii and subsequently described in multiple species of aquatic turtles on 3 continents (Laveran and Mesnil, 1902; Duszynski and Morrow, 2014); (6) Eimeria motelo from the yellow-footed tortoise, Chelonoidis (formerly Geochelone) denticulata, from Peru (Hurkováet al., 2000); and (7) Eimeria stylosa in the red-eared slider from Texas (McAllister and Upton, 1989). Overall, oocysts of E. grayi are considerably larger than other coccidians with surface projections (Table I).</p> </div>	https://treatment.plazi.org/id/03F987BDFFE9FFC7904DF9BA7C4E5BA1	Public Domain	No known copyright restrictions apply.
