Known distribution. BRAZIL (Amazonas).

Remarks. This species differs from all other species in the C. simpliciforma Group due to the lobes of tergum X being narrow and widely separated basally; inferior appendages, in lateral view, each wide at apex and shallowly incised, with subequal dorsal and ventral lobes; and the phallus with numerous short, sclerous internal spines.

Chimarra (Chimarrita) akantha was previously known only from the type locality (Manaus, Reserva Ducke). With the specimens collected in the present study, the species distribution is extended to the southern-most part of Amazonas state .
