Amphilectus is a genus of marine sponges in the family Esperiopsidae (Demospongiae, Poecilosclerida).[2]
The genus was originally described by Vosmaer (1880).[2]
In Esperiopsidae, generic assignments in the literature rely on microscleres and their skeletal/spicule organization. For Amphilectus, the defining feature emphasized in the Esperiopsidae treatment is that it has a single microsclere type (palmate isochelae), with no additional microscleres.[3]
When distinguishing Amphilectus from the closely related genus Esperiopsis, additional characters discussed include the absence of extra microscleres and the tendency for smaller styles in Amphilectus; however, a commonly referenced style-size boundary is treated as loosely applicable because of overlap among species.[3]
Amphilectus is reported as a genus containing 17 species, with a mainly temperate/cold-water affinity, occurring across multiple ocean basins including the North Atlantic, North Pacific, South Atlantic, and South Pacific.[3]
