Diagnosis

Females of Tantra sichid gen. et sp. nov. can be distinguished from those of other species of Tantra by the opisthosoma coloration overall dark olive-green, posteriorly lighter, with two round silver guanine patches ventrally (Fig. 48A–C).

Etymology

The specific name is derived from ‘sichid’ which means ‘black’ in the Kuna language, currently spoken by the Kuna native people of Panama, and refers to the overall dark coloration of this species.
