“…Since Duszynski and Morrow's treatise ( 2014), I find that only one new Isospora (Hnida 2015) and one new species of Haemogregarina (Telford et al 2009) have been added to named species from turtles. However, three very interesting molecular phylogenetic studies on what we currently think are familiar coccidian genera (e.g., Caryospora, Eimeria, Goussia) have shed more light on what we do not know about turtle coccidians, and likely has contributed at least five more species inquirendae to the apicomplexan 'species' mix in turtles.…”

Over the last two decades my colleagues and I have assembled the literature on a good percentage of most of the coccidians (Conoidasida) known, to date, to parasitise: Amphibia, four major lineages of Reptilia (Amphisbaenia, Chelonia, Crocodylia, Serpentes), and seven major orders in the Mammalia (Carnivora, Chiroptera, Lagomorpha, Insectivora, Marsupialia, Primates, Scandentia). These vertebrates, combined, comprise about 15,225 species; only about 899 (5.8%) of them have been surveyed for coccidia and 1,946 apicomplexan valid species names or other forms are recorded in the literature. Based on these compilations and other factors, I extrapolated that there yet may be an additional 31,381 new apicomplexans still to be discovered in just these 12 vertebrate groups. Extending the concept to all of the other extant vertebrates on Earth; i.e. lizards (6,300 spp.), rodents plus 12 minor orders of mammals (3,180 spp.), birds (10,000 spp.), and fishes (33,000 spp.) and, conservatively assuming only two unique apicomplexan species per each vertebrate host species, I extrapolate and extend my prediction that we may eventually find 135,000 new apicomplexans that still need discovery and to be described in and from those vertebrates that have not yet been examined for them! Even doubling that number is a significant underestimation in my opinion.

A new species of Isospora Schneider, 1881 (Apicomplexa: Eimeriidae) from the twist-necked turtle Platemys platycephala (Schneider) (Testudines: Chelidae) in Brazil

A new coccidian species of the genus Isospora Schneider 1881 (Apicomplexa, Eimeriidae) is reported from a single specimen of chelid turtle, Platemys platycephala (Schneider, 1792), obtained in a flooded area of the Amazonian municipality of Altamira, in Pará State, northern Brazil. The oöcysts of Isospora platemysi n. sp. are subspheroidal, 19.0-24.0 × 22.5-18.5 (22.6 × 20.8) µm in size [length/width ratio 1.0-1.1 (1.1)], with a colourless wall, 1.0-1.9 (1.4) wide, with two smooth layers; polar granule is present, oöcyst residuum and micropyle are both absent. The sporocyst is ovoidal, 10.0-12.1 × 8.0-10.0 (11.0 × 9.1) µm [length/width ratio 1.1-1.3 (1.2), with a knob-like Stieda body. Sub-Stieda body is present, rounded irregular-trapezoidal; para-Stieda body is absent. Sporocyst residuum is dispersed and composed of granules of differing sizes. This is only the fifth record of Isospora in chelonians, and the first report of a coccidian parasite of the genus Platemys.
