Etymology. The specific name is an adjective referring to the dark transversal bands present in the dorsal region of its abdomen.

Diagnosis. Gippsicola lineata n. sp. differ from G. raleighi and G. minuta n. sp. by the presence of a sperm duct with one and a half convolutions, and from G. robusta n. sp. by having a piriform bulb, with a thinner embolus ( Figs 9 A–B). Females present an anterior receptaculum longer than G. robusta n. sp., with thickened and irregular ventral entapophyses ( Figs 9 C–D). This species present a greyish abdomen, with dark dorsal transverse bands interleaved with whitish ones ( Figs 8 A–D).
