Fissarena

Fissarena is a genus of spiders belonging to the family Trachycosmidae. These spiders are native to Australia. Characterized by their flattened body shape and cryptic coloration, they are often found under bark, rocks, and leaf litter in various terrestrial habitats across the continent.

The spiders of the genus Fissarena are typically medium-sized, with a body length ranging from approximately 5 to 15 millimeters. They are active hunters, preying on small insects and other invertebrates. Distinguishing features of Fissarena spiders include specific arrangements of their eyes, leg spination patterns, and the morphology of their reproductive organs.

Taxonomic classification of Fissarena species is based on morphological characteristics, and ongoing research may refine the understanding of species boundaries and phylogenetic relationships within the genus.
