Subfamily Gallobathynellinae

Amended diagnosis (after Serban 1989a, 1989b, Camacho et al. 2018b)

Antennule six- or seven-segmented. Endopod of antenna three- or five-segmented. Apical part of paragnaths with thin setae. Prehensile mandibular palp one- or three-segmented, males and females with similar or different claws on terminal article; pars incisiva [incisor process] of mandible with two simple teeth and pars molaris [molar process] (with processus incisivus accesorius [accessory incisor process]) of mandible normally formed by two parts, more or less complex, with simple or denticulate teeth. Endopod of ThI-V, or ThII-V, or ThII-VII, or only on ThVI and ThVII (ex. Sardobathynella cottarelli Serban, 1973 ) three- or four-segmented in all thoracopods; male ThVII without coxal endite. Penial region of male ThVIII with outer lobe (O.lb.) and frontal projection (Fr.prj.) (‘prolongment rostral’) apically developed, or with large outer lobe, frontal projection, and one additional lobe; basipod well developed, vertical or inclined, generally with a frontal crest (Fr.crt.) terminating in a spur (S.fr. crt.); exopod similar to the rest of thoracopods, always present; endopod small, one-segmented, or absent. Female ThVIII variable, similar to Bathynellinae , biramous, with rami similar or dissimilar in length, or uniramous and reduced to only two articles (coxopod and basipod); exopod with two terminal setae, dissimilar in length; coxal seta elongated or reduced. Sympod of uropod with three to five spines; endopod with two or four claws. Furcal rami with second spine, longer than the other four in almost all taxa.
