Like most other members of the genus Dares, the species is native to Borneo, more precisely in the northwest of the island.

As is typical for the genus, the abdomen of the females of Dares validispinus is widest in the middle and also highest there in adult, egg-laying specimens.

On the thorax, more precisely on the meso- and metathorax, several of these yellow areas are arranged in such a way that they look like a brown-yellow, especially from the side Stripe patterns work, which rise slightly towards the spines and thus appear a bit wavy.

[1][2] Dares validispinus is native to a wide strip in the northwest of the island of Borneo, where it has been detected from Sarawak via Brunei to Sabah.

These are approximately spherical and about 3.2 millimetres (0.13 in) in diameter and dark brown in color with irregular gray-brown spots.

One of the arms points in the direction of the lid (operculum) and almost reaches it, while the other two run circularly around the lower quarter of the egg.

From the two males described by Stål and deposited as paralectotypes in the Natural History Museum Vienna, one animal was selected as the lectotype.

[1][5][6] Allan Harmann and Mary Salton brought the first living specimens of this species from the Niah National Park in Sarawak to Great Britain in 1979/80.

Further imports were made, for example, in 1994 by Mel Herbert from Brunei and in 1996 by Frank H. Hennemann and Oskar V. Conle from Mount Serapi in Sarawak.

A stock that Jonah Voo Zhong Xuan collected in Sabah in 2017 and has been breeding since then is referred to as Dares validispinus 'Kiansom' with details of the place where it was found.

In breeding, the leaves of bramble and many other Rosaceae are eaten, as well as those of hazel, oak and Gaultheria shallon (salal).
