There are two large projections on top of the head.
The described male has an abdomen mottled brown and beige, with a bright white patch on each side and tufts of white hairs.
Male Eriauchenus zirafy have finely branched structures at the end of the pedipalp beside the mouth, including a cluster of tiny bumps and pores. These details are much smaller than the conspicuous projections on the head.
The name zirafy, given in 2018, means giraffe in Malagasy. The revision compared the species with Eriauchenus bourgini, which shares large head projections. The male conductor has five processes in zirafy, compared with four in bourgini.
In zirafy, four long processes include one that bifurcates, giving five ends. The cluster of bumps and pores at the base is also diagnostic. Detailed examination therefore distinguishes spiders with similar overall head shapes.
An extinction-risk assessment has not been added yet.
Madagascar National Parks lists clearing, selective logging, poaching and bushfires among pressures on Masoala. Restoration and ecological monitoring are listed as ongoing conservation work. Repeated surveys of this spider’s collecting localities and vegetation could clarify its occurrence.
