Classification Salazar-Vallejo (2017) presented his revision of Bradabyssa as four informal groups:Group “crustosa" contains those species whose members have a homogeneous cover with sediment particles embedded in the tunic, such that individual papillae are not detected, unless this cortex is removed. The species included are B. indica n. sp., B. mexicana n. sp., B. minuta (Amoureux, 1986), and B. sachalina (Annenkova-Chlopina, 1922) n. comb.
Group “nuda” includes all species whose bodies are provided with tiny, often abundant papillae, which may be eroded giving the body a naked appearance. The species included are B. alaskensis n. sp., B. antarctica (Hartman, 1978) n. comb., B. bransfieldia (Hartman, 1965) n. comb., B. nuda (Annenkova-Chlopina, 1922) n. comb., B. rugosa (Hansen, 1880) n. comb., and B. strelzovi (Jirkov & Filippova in Jirkov, 2001) n. comb.
Group “verrucosa” contains those species whose bodies have large tubercles or verrucae, which might have distal, fragile papillae; these tubercles are often relatively larger in posterior chaetigers. Verrucae can be of similar size, or being of at least two distinct sizes; the larger papillae may be basally enlarged generating rounded tubercles. The species included are B.abyssalis (Fauchald, 1972) n. comb., B. annenkovae (Buzhinskaja, 2001) n. comb., B. elinae n. sp., B. irenaia (Chamberlin, 1919) n. comb., B. levensteinae n. sp., B. mammillata (Grube, 1877) n. comb., B. ochotensis (Annenkova-Chlopina, 1922) n. comb., B. papillata Hartman, 1967, B. tenebricosa (Berkeley, 1968) n. comb., n. status, and B. verrucosa (Chamberlin, 1919) n. comb.
Group “villosa” includes those species whose bodies are provided with thin, long papillae, of similar size along the body, or becoming slightly larger laterally. The species included are B. capensis (Day, 1961) n. comb., n. status, B. harrisae n. sp., B. hartmanae n. sp., B. ilyvestis (Hartman, 1960) n. comb., B. intoshi (Caullery, 1944) n. comb., B. jirkovi n. sp., B. kirkegaardi n. sp., B. monnioti n. sp., B. parthenopeia (Lo Bianco, 1893) n. comb., B. pilosa (Moore, 1906) n. comb., B. pluribranchiata (Moore, 1923) n. comb., B. setosa (Verrill, 1873) n. comb., B. mezianei n. sp., B. tzetlini (Jirkov & Filippova in Jirkov, 2001) n. comb., B. villosa (Rathke, 1843) n. comb., and B. whiteavesi (McIntosh, 1885) n. comb

Diagnosis Fide Salazar-Vallejo, 2017: "Body fusiform, sometimes cylindrical with swollen ends. Cephalic cage chaetae often abundant, delicate. Body papillae abundant, at least dorsally, papillae tiny to very large, sometimes forming large transverse ridges. Notochaetae multiarticulate, at least distally, few, delicate. Neurochaetae aristate, rarely expanded subdistally. Branchiae usually abundant, thin cirriform filaments, sessile on branchial plate, separated into two lateral groups.
Salazar-Vallejo separates Bradabyssa from Brada as follows: Neurochaetae aristate spines; branchiae usually abundant filaments =.Bradabyssa Hartman, 1967. Neurochaetae blunt, falcate spines; branchiae only 8 cirriform filaments = Brada Stimpson, 1853. Salazar-Vallejo (2017: 9 figure 1) illustrates the difference between the two in body shape and neurochaeta type. In brief "Brada differs from Bradabyssa by having blunt, often falcate neurochaetae, and only 8 branchial filaments, whereas Bradabyssa has aristate neurochaetae, usually with hyaline tips, and usually many branchial filaments" [details]
Etymology Not stated. Hartman (1967) has nothing on the etymology, but it clearly is Latin 'abyssus' combined with the existing genus Brada, to indicate a deepsea genus. [details]
Grammatical gender Not stated, but Bradabyssa is feminine as the type species has a feminine adjectival name of 'papillata'. Also 'abyssus' is a feminine Latin noun (originally from Greek), and Hartman has altered the suffix to the feminine-like form of 'abyssa' [details]
