Megadactylus giganteus Broili, 1929 Eschenbachiellus wuttkensi Briggs & Bartels, 2001 Bundenbachiellus is an extinct genus of arthropod described from the Lower Devonian Hunsrück Slate of Germany.

[4] In 2001, new taxon Eschenbachiellus wuttkensis was described from complete specimen NM PWL 1997/3-LS, along with other three species of arthropod such as enigmatic Wingertshellicus backesi.

[1][5] Its cephalon have semicircular head shield, a uniramous and a long biramous antenna and three pairs of appendages, and lacked eyes.

[1][5] However, in 2014, new genus of arthropod, Enalikter has described from Silurian Herefordshire Lagerstätte, and it shared morphological similarities with Bundenbachiellus although there are some different characters.

Alongside Enalikter, Bundenbachiellus is included in the family Enaliktidae, and probably they are members of the stem clade Leanchoiliida.
