Diagnosis

Diagnosis_Species: All life cycle stages possess 18−21 somatic kineties; tomite stage, ovoid with blunt anterior end; oral cavity bordered by 3 ‘oral’ kineties; infecting a broadcast-spawning euphausiid distributed along the northeastern Pacific Ocean.
Body_length: 44-57 µm
Body_wide: 26-38 µm
Kineties_total: 18-21
Kineties_oral: 2-4

Etymology

The species name derives from similis (Latin meaning ‘like, resembling’) and is givenvbecause this species is the fourth described species of Pseudocollinia, which appears to be a complex ofvcryptic species of parasitoids infecting euphausiids of the northeastern Pacific Ocean

Type illustration / Type locality / Type specimen

Type locality: Northeast Pacific, along the Oregon coast, USA (43° 13’ N, 124° 59’ W).
Type material: A protargol-stained slide of P. similis sp. nov. cells in the tomite stage (Holotype USNM 1231431 [IZ]) was deposited in the International Protozoan Type Slide Collection of the Department of Invertebrate Zoology of the National Museum of Natural History, Smithsonian Institution. The holotype
(Figs. 3A,B & 4B) as a cell from isolate 29 is circled in black on the underside of the slide.
Type host: Thysanoessa spinifera Holmes, 1900
