Diagnosis Body tripartite (tentative) and elongated, bearing a pair of tentacles, bicellular eyes, and possible nuchal organs; the anterior part of the body being a reversed trapezoid in outline; at least seven pairs of uniramous parapodia with simple chaetae; pygidium large and bifid. (Zhao et al 2023) [details]Etymology authors: Gaoloufangchaeta is a compound of "Gaoloufang, referring to the location where the fossil was found [and] chaeta [hair]/bristles], a diagnostic characteristic of polychaetes." [details] Grammatical gender The authors contribute no information on the gender of the new genus, apart from the spelling they use. However, 'chaeta' is feminine, therefore the genus is feminine. This is in conflict with the species-group name of bifurcus which is a descriptive adjective and should agree with the genus gender, therefore should be bifurca rather than the masculine bifurcus.
