Etymology The etymology of Loimia is unknown. Usages outside of references to Loimia terebellids are almost non-existent. No usages as a personal name have been found. Malmgren was a Finnish biologist. and the word does occur in Finnish where one meaning is blanket, and another is warp (a twist or distortion), although how these relate to the worm is not known. Perhaps warp is a reference to the tentacles. The gender is feminine as Malmgren linked it with medusa as a species name and authors following created feminine adjectival species epithets. [details]

Status Jirkov & Leontovich (2017) proposed the synonymy of Loimia into Axionice (along with several other genera including Lanice). Lavesque et al (2021: 35) rejected this synonymy, considering the genus Loimia well defined "with all species having three pairs of arborescent branchiae, uncini in double rows until segment 20, uncini pectinate (at least on the thoracic segments) and lateral lobes well-developed on segment 1.

Diagnosis Generic diagnosis by Lavesque et al. (2017: 936): "Branchiae on segments 2–4; lateral lappets on segments 1 and 3, 1 and 2/3 (in combination of segments 2 and 3) or 1, 3 and 4; ventral shields from segment 2 or 3; nephridial papillae on segments 3–4 and 6–8; 17 pairs of thoracic notopodia from segment 4; chaetae alimbate, unilimbate, symmetrical or asymmetrically bilimbate, smooth tipped; neuropodia from segment 5, uncini avicular or pectinate with a single vertical series of teeth, arranged in single rows on segment 5–10, in double rows, back to back, up to segment 20, and in single rows along the abdomen; pygidium sometimes with anal cirri or papillae." [details]Diagnosis Original diagnosis by Malmgren (1866: 380): "Corpus antice inflatum, postice attenuatum ventre subplano, dorso convexo. Branchiae, paria 3, arborescentes, posteriores gradatim minores, ramosissimae, ramulis ultimis brevissimis numerosissimisque. Fasciculi setarum capillarium a segmento quarto, h. e. tertio branchifero, incipientes in 17 segmentis. Setae capillares apice paulo curvato attenuato anguste limbatae. Tori uncinigeri a segmento secundo setigero incipientes, pone ultimum segmentum setigerum in pinnulas uncinigeras apice rotundatas mutati, per totum corpus obvii. Pinnulae uncinigerae deorsum vergentes per latera ventris plani decurrentes. Uncini pectiniformes 5-dentati, dentibus validis curvatis acuminatis, uniseriales, in segmento uncinigero septimo et novem sequentibus autem biseriales. Scuta ventralia antice conspicua." [details]
