Most eugregarine apicomplexans infecting the intestines of marine invertebrates have been described within the family Lecudinidae and the type genus Lecudina. [...] Key Result Lecudina longissima and Lecudina polymorpha were both isolated from the intestines of Lumbrineris japonica (Polychaeta). Difficilina tubulani sp. nov. was isolated from the nemertean Tubulanus polymorpha and Difficilina paranemertis sp. nov. was isolated from the nemertean Paranemertes peregrina. This is the first report of molecular…Expand
Molecular Phylogenetic Positions of Two New Marine Gregarines (Apicomplexa)—Paralecudina anankea n. sp. and Lecudina caspera n. sp.—from the Intestine of Lumbrineris inflata (Polychaeta) Show Patterns of Co‐evolution
Gregarine apicomplexans are unicellular parasites commonly found in the intestines and coeloms of invertebrate hosts. Traits associated with the conspicuous feeding stage of gregarines, known as theExpand
Molecular systematics of marine gregarine apicomplexans from Pacific tunicates, with descriptions of five novel species of Lankesteria.
TLDR
The molecular phylogenetic data suggested that species of Lankesteria with surface knobs form a clade that is nested within a paraphyletic assemblage species of Lanka with epicytic folds, whereas two of the species were covered with a dense pattern ofEpicytic knobs. Expand

TLDR
Four gregarine species that inhabit the intestines of three spionid species from the Patagonian coast, Argentina are described for the first time, and a new species, Polyrhabdina madrynense sp. Expand
New Gregarine Species (Apicomplexa) From Tunicates Show an Evolutionary History of Host Switching and Suggest a Problem with the Systematics of Lankesteria and Lecudina.
TLDR
Four new species of marine eugregarines infecting ascidian hosts and hypothesize that the continued addition of new species from polychaete and tunicate hosts as well as the construction of multigene phylogenies that include type-material will further dissolve the currently accepted distinction between Lankesteria and Lecudina.

Molecular Phylogeny and Ultrastructure of Caliculium glossobalani n. gen. et sp. (Apicomplexa) from a Pacific Glossobalanus minutus (Hemichordata) Confounds the Relationships Between Marine and Terrestrial Gregarines
TLDR
This study isolated a novel marine gregarine from the hepatic region of a Pacific representative of the hemichordate Glossobalanus minutus, and reports the first ultrastructural and molecular data from any g Regarine infecting this distinctive group of hosts. Expand
Molecular Phylogeny of Marine Gregarine Parasites (Apicomplexa) from Tube‐forming Polychaetes (Sabellariidae, Cirratulidae, and Serpulidae), Including Descriptions of Two New Species of Selenidium
TLDR
A species discovery survey of Selenidium from tube‐forming polychaetes uncovered five different morphotypes of trophozoites (feeding stages) living within the intestines of three different polychaete hosts, two of which were established in this study. Expand

TLDR
A new genus and species of marine gregarine isolated from the intestine of a polynoid host (Lepidonotus helotypus) collected from Hokkaido, Japan is described and established and a molecular phylogenetic position for Loxomorpha cf. Expand
Molecular Phylogeny of Pacific Archigregarines (Apicomplexa), Including Descriptions of Veloxidium leptosynaptae n. gen., n. sp., from the Sea Cucumber Leptosynapta clarki (Echinodermata), and Two New Species of Selenidium
TLDR
This work describes two novel species of Selenidium and describes a novel genus of archigregarine, Veloxidium leptosynaptae n. Expand
Morphology and Phylogenetic Position of Two New Gregarine Species (Apicomplexa: Eugregarinorida) Parasitizing the Lubber Grasshopper Taeniopoda centurio (Drury, 1770) (Insecta: Orthoptera: Romaleidae) in Mexico
TLDR
Two new eugregarine species from the gut of the host are described: Amoebogregarina taeniopoda n. Expand
Comparative ultrastructure and molecular phylogeny of Selenidium melongena n. sp. and S. terebellae Ray 1930 demonstrate niche partitioning in marine gregarine parasites (apicomplexa).
TLDR
Molecular phylogenetic analyses of small subunit rDNA sequences derived from single-cell PCR unexpectedly demonstrated that these two gregarines are close sister species, demonstrating a compelling case of niche partitioning and associated morphological divergence in marine gregarine apicomplexans.

MOLECULAR PHYLOGENY AND SURFACE MORPHOLOGY OF MARINE ASEPTATE GREGARINES (APICOMPLEXA): SELENIDIUM SPP. AND LECUDINA SPP
TLDR
Eugregarines formed a monophyletic group with the neogregarine Ophryocystis, suggesting that trophozoites with elaborate cortex folds and gliding motility evolved only once. Expand
Phylogeny of gregarines (Apicomplexa) as inferred from small-subunit rDNA and beta-tubulin.
TLDR
The congruence of SSU rDNA and beta-tubulin trees with one another and with morphological data does suggest that further sampling of molecular data will eventually put gregarine diversity into a phylogenetic context. Expand
