The described male has a yellowish-white abdomen mottled with light brown.
The described male has two short spines on top of the head. The described female has a darker abdomen, mottled dark brown and pale yellow.
In the described male Eriauchenus goodmani, the anterior median eyes are almost flush with the surrounding surface. A long spine projects perpendicularly from near the base of each chelicera. The male had chelicerae 1.65 mm long with the spine 0.23 mm from the base; the described female’s chelicerae were 2.87 mm long, with the spine 0.20 mm from the base.
The 2018 description was based on a male and female collected at separate Andohahela sites in 1995, at 1,500 and1,875 metres respectively. Details including the male reproductive organ’s greatly elongated, blunt-tipped conductor distinguished the species from similar spiders. Its name honours collector Steven Goodman and his work on Madagascar’s biodiversity.
An extinction-risk assessment has not been added yet.
At Andohahela, where the specimens were collected, the conservation fund FAPBM identifies slash-and-burn agriculture, bush fires and illegal selective logging among pressures on habitats. It describes collaborative management involving local people through park and protected-area support committees. This is regional participation in conservation and development activities.
