Parviplana hymani Faubel, 1983

Parviplana hymani Hyman, 1953a: 312–315 , figs 60–61 (type locality: Tomales Haed, Marin Country, California, United States).

Parviplana hymani – Brusca 2005: 69 (new record from Gulf of California, Mexico, checklist).

Distribution

Newport Bay and Tomales Haed, Marin Country, California; Gulf of California, Mexico.

Habitat

Benthic (on a rocky shore, among a mass of sponge and bryozoans).

Remarks

Parviplana hymani lacks nuchal tentacles, has an ejaculatory duct through the prostatic vesicle, and has a bulbous vagina. In the WoRMS database, Parviplana californica is listed as a junior synonym of Parviplana hymani and Leptoplanella californica (= Stylochoplana californica ). However, this classification is not correct. Hyman (1953a) described a new genus, Parviplana , and moved Leptoplanella californica (= Stylochoplana californica ) into this genus, creating the combination Parviplana californica . In the same publication, a new specimen was also described under that name. However, Faubel (1983) proposed a new specific epithet, Parviplana hymani , which invalidated the synonyms Parviplana californica and Stylochoplana californica for this species.
