Pseudicius mirus

Pseudicius mirus is a small spider, typical of the genus. The male has a carapace that is typically 2.2 mm (0.087 in) long and 1.6 mm (0.063 in) wide. It is oval, widest towards the middle with a flattened forward part, and covered in dense short white hairs. It has a long, brown bristles near its eyes. The spider has a clypeus that is low and brown. The chelicerae are brown with one tooth visible to the front and two to the back. The labium is light brown and the sternum is yellow. The spider's abdomen is typically 2.3 mm (0.091 in) long and 1.4 mm (0.055 in) wide. It is oval like the carapace, but greyish-yellow with a wide brown band stretching across its middle. It has light hairs along the sides and brown bristles along the underside, which is light. The spinnerets are yellowish-grey and the legs are yellow. The foremost legs are longer and thicker than the others, and are marked with a brown stripe. All the legs are covered with long light hairs. Dense white hairs cover much of the copulatory organs, which are unusual and so help distinguish the species from others in the genus. The pedipalps are very dark brown, nearly black.^[12] The palpal bulb is oval with a narrow triangular lobe to the base. The embolus is short and blunt.There are two tibial apophyses, one with a small hook jutting out from it, the other more blunt. It is this small hook-like spike that most differentiates the species from others in the genus.^[13] The female has not been described.^[1]

Pseudicius spiders can be found across Afro-Eurasia and the Eastern hemisphere.^[14] Pseudicius mirus is endemic to Yemen.^[1] The species has limited distribution. The holotype was found on Socotra Island during 1999.^[12] Examples have not been found in any other areas of the country.^[15]
