The insemination ducts are relatively short and the spermathecae spherical, but they are both thicker than those found in other examples.

Hasarius insularis is a species of jumping spider that was first described by Wanda Wesołowska and Antonius van Harten in 2002.

[6] Molecular data demonstrates that the genus is closely related to Habrocestum and Chinattus in a group called Hasarieae.

[7][8] Phylogenetic analysis has shown that the genus is related to the genera Neaetha and Salticus.

[9] In 2016, Jerzy Prószyński grouped the genus with 32 other genera of jumping spiders under the name Chrysillines in the supergroup Chrysilloida.

The carapace is rather high and is reddish-brown on top with a lighter brown area to the middle.

The insemination ducts are relatively short, with narrow at their entrances and a wider section deeper in, and lead to spherical spermathecae.

[12] The walls of the spermathecae and insemination ducts are particularly thick, which distinguishes the spider from others in the genus.

[1] Hasarius spiders can be found across many warmer countries across Africa and Asia, and have also been observed in greenhouses in cooler climates.
