Abstract
Background
The genus Ibana Benjamin, 2014 was established, based on the type species Ibana senagang Benjamin, 2014 from Borneo, Malaysia. No species of this genus has been recorded from China.

New information

The distribution of the new species in Jiangxi Province is mapped.

Keywords: taxonomy, spiders, types, Jiangxi

Ibana gan Liu & Li, sp. n.

Diagnosis: The new species can be distinguished from Ibana senagang Benjamin, 2014 (Benjamin 2014: 181, figs. 1G, 3A–C) by the transverse ridge of copulatory openings present (vs. absent), the copulatory ducts extending from anterolateral to posteromedial part of epigyne (vs. from medial to anteromedial) and the oval, contiguous spermathecae (vs. close touching) (Figs 2, 3).

Etymology: The specific name refers to the Chinese abbreviation for Jiangxi Province; noun in apposition.

Distribution: Known only from the type locality in Jiangxi Province, China
