Izithunzi silvicola

Izithunzi silvicola exhibits typical sexual dimorphism, with females being larger than males. The female has a total length of 8.8 mm. The leg formula is 1423, meaning the first legs are longest followed by the fourth, second, and third legs. Females are characterized by an epigastrium plate extending posteriorly beyond the middle of the opisthosoma, and a triangular, swollen postepigastrium plate located below the epigastric furrow. The chelicerae have six bracket setae on the promargin and an extra small tooth next to the apical tooth on the cheliceral furrow. The overall coloration is dark brown without chevron patterns on the opisthosoma. Males are smaller with a total length of 5.93 mm and lighter coloration than females. The male pedipalp is elongated with a swollen cymbium that is 1.5 times longer than the base of the copulatory bulb.

Izithunzi silvicola is endemic to South Africa, where it is recorded from the Western Cape and Eastern Cape provinces. The species has been found in several protected areas including Knysna forests, Harkerville State Forest, Diepwalle Forest Station, and Tsitsikamma National Park. Its distribution is restricted to the Knysna-Amatola montane forests.
