Aebutinoides Mello-Leitão, 1943 = Metaltella Mello-Leitão, 1931 (Lehtinen, 1967: 209)

type Amaurobius iheringi Keyserling, 1891; gender feminine

N.B.: transferred from the Dictynidae to the Amaurobiidae by Lehtinen, 1967, to Amphinectidae by Davies, 1998a: 242 and to Desidae by Wheeler et al., 2017: 606; considered a senior synonym of Aebutinoides Mello-Leitão, 1943c: 101 [urn:lsid:nmbe.ch:spidergen:05169] (type A. tigrinus Mello-Leitão, 1943) (transferred from the Dictynidae) by Lehtinen, 1967: 209 and of Exlinea Lehtinen, 1967: 234 [urn:lsid:nmbe.ch:spidergen:05173] (type Clubiona rorulenta Nicolet, 1849) by Leech, 1971: 26; transfer of Metaltella simoni to Amaurobiidae (Murphy & Roberts, 2015: ix) not sufficiently justified and is not accepted here, furthermore is it not the type species of the genus.
