Genus Aquattuor Frederiksen, 2013

Type species

Aquattuor denticulatus Frederiksen, 2013 (Tanzania), by original designation.

Other included species

Nine (Enghoff 2020).

Diagnosis

Differs from all other genera of Odontopygidae by the large, rectangular, detachable limbus flaps (Frederiksen 2013b; Enghoff & Frederiksen 2015; Enghoff 2020).

Remarks

Eight of the ten species in the genus are Eastern Arc endemics. Aquattuor fasciatus (Attems, 1896) and A. claudiahempae Enghoff & Frederiksen, 2015 have been found at various Tanzanian localities outside the Eastern Arc, and may by synonymous (Enghoff 2020).

In the diagnosis of A. fasciatus Enghoff (2020) stated: “Shares a short (as broad as long, or slightly longer) gonopodal palette with A. claudiahempae, A. fasciatus, A. stereosathe, A. submajor and A. udzungwensis . ” This, of course makes no sense – it should have been “Shares a short (as broad as long, or slightly longer) gonopodal palette with A. claudiahempae, A. denticulatus, A. stereosathe, A. submajor and A. udzungwensis . ” I am grateful to Carlos Martínez for having spotted this.
