Pseudicius dentatus or the Opathe Pseudicius Jumping Spider is a species of jumping spider in the genus Pseudicius that is endemic to South Africa. The spider was first defined in 2013 by Wanda Wesołowska and Charles Haddad. The spider is small, with an oval carapace between 1.7 and 2.0 mm (0.07 and 0.08 in) long and an abdomen between 1.7 and 2.9 mm (0.07 and 0.11 in) long. The female is larger than the male. The abdomen has a pattern of white spots in pairs, the female having clearer and larger spots than the male. The spider has yellow legs, the front pair being longer and more robust. The spider's copulatory organs are distinctive. The female has two pockets lining the sides of the furrow in the epigyne. The male has a broader embolus than the otherwise similar Psenuc dependens. It can also be distinguished by its serrated tibial apophysis that is recalled in its specific name, which can be translated "toothed".
