Etymology authors: Manayunkia occidentalis is named "from the Latin word for “west”, to contrast with M. speciosa, which occurs in eastern and central North American drainages." [details]
Habitat Known from rocks and periphyton from the Klamath River, California, from below Iron Gate Dam (41°52’02.6”N 122°48’37.4”W) and from the Willamette River, Oregon (44°34’57.7”N 123°13’41.5”W). "Live annelids were found in clusters of tubes, most often attached to rocks or intertwined with periphyton. Females were observed frequently with broods of larvae in their tubes. Males and females with overt parasite infections often lacked gametes." [details]
Identification According to Bick & Bastrop (2025: 36) Manayunkia occidentalis was previously misidentified as Manayunkia speciosa in reports by Hazel 1966: 533–535, fig. 1. – Verner 1981: 182–183. – Wilson et al. 2010: 183–191, fig. 2. [details]
Type locality Klamath River, California, North America, 41.8672 N, -122.8098 E [details]
