Etymology The derivation of Anobothrus (masculine) was not stated by Levinsen but is a combination of ano- (over, above) or of an- (not, without, negative) with the masculine Greek -bothros (trench). How this was intended is not possible to determine. Thus, as Latinized, Anobothrus is masculine. Chávez-López et al (2025) suggest "Anobothrus" may refer to the apparent lack of nephridial papillae to which Levinsen referred in his comparison of Ampharete gracilis with Ampharete [details]

From editor or global species database
Diagnosis (after Jirkov, 2009) Prostomium Ampharete-type. One pair of notopodia in posterior thorax (usually TU–8 or TS–5 of the latter) slightly elevated, connected by a low glandular band (sometimes visible only after staining), modified notopodial chaetae sometimes only slightly differ from notopodial chaetae. Connecting band ciliated at least in the type species (Holthe, 1986a). Three or four pairs of branchiae, three pairs form transversal rows without any median gap, the forth (branchiae of S–6), if present, located behind the innermost and connected to them; the inner four branchiae more or less distinctly shorter than outer ones. Circular band in anterior thorax, anterior to notopodia of TU–3 or more rarely TU–2 or TU–1 (?). A pair of large nephridial papillae situated behind branchiae. Neuropodiae of first two AU of thoracic type, followed by normal abdominal ones. [details]Diagnosis (Diagnosis as modified by Chávez-López et al. 2025). Ampharetins with 17 thoracic segments: 15–16 chaetigers, 12 thoracic uncinigers from segment VI (TC4–5). Prostomium Ampharete-type. Segment II with paleae. Segment III with very small, inconspicuous chaetae or without chaetae. Segments IV–XVII with capillary notochaetae. Four pairs of smooth branchiae. Three branchial pairs arranged in transverse row without interbranchial gap, fourth pair immediately behind them. All branchial bases fused forming a high membrane. One or two dorsal nephridial papillae immediately behind innermost pair of branchiae; if two, closely spaced. Buccal tentacles smooth. Circular band on anterior thoracic unciniger 3 (TC6–7). Dorsal ridge on posterior thoracic uncinigers 8–9 (TC11–12). Thoracic uncini with 2 rows of teeth in frontal view. [details]
Etymology The derivation of Anobothrus (masculine) was not stated by Levinsen but is a combination of ano- (over, above) or of an- (not, without, negative) with the masculine Greek -bothros (trench). How this was intended is not possible to determine. Thus, as Latinized, Anobothrus is masculine. Chávez-López et al (2025) suggest "Anobothrus" may refer to the apparent lack of nephridial papillae to which Levinsen referred in his comparison of Ampharete gracilis with Ampharete [details]
Grammatical gender Masculine. Bothrus as Latinized is masculine. Almost all the adjectival species names are masculine to match. Only Anobothrus antarctica Monro, 1939 (currently placed in Anobothrella) is incorrectly gender adjusted. [details]
