Etymology: The specific name is a patronym in honour of Mathew Sibusiso Zondi, who taught author Griswold to say ‘hello’, ‘thank you’ and ‘we are collecting spiders’ in Zulu.

Diagnosis: Females of I. zondii sp. nov. resemble those of I. lina sp. nov. by the inner and outer spermathecae separated, the vulval plates pressed together anteriorly, and the anterior plate heavily sclerotized ( Figs 10, 16, 23), but can be distinguished by the anterior plate strongly curved anteriorly (inverted V shaped), the posterior plate straight and the dorsal receptaculum partially integrated to the posterior plate ( Fig. 23), while I. lina sp. nov. has anteriorly curved vulval plates and integrated dorsal receptaculum ( Figs 10, 16).
