Uloborus diversus is a species of cribellate orb weaver in the spider family Uloboridae. It is found in the desert regions of the Southwestern United States and Mexico. ^{[1] [2] [3] [4]} It is an important model species for understanding the evolution of spidroins and understanding orb-weaving behavior. ^[5] To provide resources for this research a 2.15-Gbp chromosome-level draft genome assembly was sequenced and assembled to 10 chromosomes. ^[6]

Description

U. diversus is typically brown, with paler colourations more common than melanic ones. ^[7] Patterns and markings vary, though most individuals have a mottled line that runs longitudinally down the abdomen. Leg markings are distinct, with visible rings. ^{[7] [8]}

U. diversus shows minor sexual dimorphism, with males sporting tibial spines and a slightly flattened abdomen. ^[7]

Taxonomy

Due to the great variability in appearance of U. diversus, many junior synonyms exist for this species. ^{[9] [10]}
