Abstract

We describe two new species of Dinychus Kramer, 1886 from fragments of the former Gondwanaland supercontinent. Dinychus indica sp. nov. from India belongs to the Dinychus woelkei -group It differs from the previously known Dinychus species on the basis of the sculptural pattern of the sternal and genital shields of female. The female of Dinychus chilensis sp. nov. from Chile has a quadrangular genital shield, which is a unique character state in the genus Dinychus . New keys to the Central and South American Dinychus and to Dinychus woelkei -group are presented.
