AppearanceThe male has v-shaped rows of hairs on its head and a pronounced white median stripe on its abdomen. The female is mottled brown. The spider can reach a length of 4–7 millimetres .
Naming''Insignitus'' is Latin for "signed", because of the white chevron on the back of the male spider, which is in the form of the letter "V". This letter was originally spelled one v above another V, which could also be interpreted as a double V or W, but usually is interpreted as "V".
Distribution''A. v-insignitus'' occurs in the Palaearctic. It is the only ''Aelurillus'' species that occurs in northwestern Europe.
