SIMILAR GENERA

Other choanoflagellates:

Codosiga:

colonial; cells clustered at the end of a common stalk, without theca or lorica; free-living, freshwater and marine.
Example (Protist Information Server):
C. botrytis (Movie)

Salpingoega:
solitary; cells with an unmineralized theca (some texts say "lorica"); free-living, freshwater and marine.
Examples (Protist Information Server):
S. buetschlii, S. depressa, S. urceolata, S. spp.

Stramenopiles:
Bicosoecids:
biflagellate, the posterior flagellum of sessile cells often used as a stalk, attaching cell to lorica or substrate; swimming cells moving "forward", with anterior flagellum in front; loricate (e.g. Bicosoeca) or naked (e.g. Cafeteria, Pseudobodo); no tentacles on cell body; cell mouth present, supported by band of microtubules.
Examples:
Bicosoeca petiolata (Protist Information Server, as Bicoeca petiolata)
Cafeteria roenbergensis (PID)
Pseudobodo tremulans (Baltic Sea Phytoplankton Checklist)

Pedinellids:
Uniflagellate, the flagellum bearing tripartite tubular hairs; swimming cells moving "forward", with flagellum in front; sessile cells often attached with cytoplasmic stalk; no theca or lorica, but may have scales and/or spines; tentacles on cell body, but not forming a collar; no cell mouth; most species with chloroplasts.
Examples (species lacking chloroplasts; find them under the micro*scope):
