Pseudocellus platnicki is a species of ricinulei classed in the family of Ricinoididae. [1]
Arachnida is a class of joint-legged invertebrate animals (arthropods), in the subphylum Chelicerata. Arachnida includes, among others, spiders, scorpions, ticks, mites, pseudoscorpions, harvestmen, camel spiders, whip spiders and vinegaroons.
Ricinulei is a small order of arachnids. Like most arachnids, they are predatory, eating small arthropods. They occur today in west-central Africa (Ricinoides) and the Neotropics as far north as Texas. As of 2021, 91 extant species of ricinuleids have been described worldwide, all in the single family Ricinoididae. In older works they are sometimes referred to as Podogona. Due to their obscurity they do not have a proper common name, though in academic literature they are occasionally referred to as hooded tickspiders.
The pygidium is the posterior body part or shield of crustaceans and some other arthropods, such as insects and the extinct trilobites. In groups other than insects, it contains the anus and, in females, the ovipositor. It is composed of fused body segments, sometimes with a tail, and separated from thoracic segments by an articulation.

Phrynidae is a family of amblypygid arachnida arthropods also known as whip spiders and tailless whip scorpions. Phrynidae species are found in tropical and subtropical regions in North and South America. Some species are subterranean; all are nocturnal. At least some species of Phrynidae hold territories that they defend from other individuals.
Pseudocellus barberi is a species of arachnid in the order Ricinulei. They can be found in Guatemala and Honduras. The type specimen was found in Guatemala.
Paolo Marcello Brignoli was a prominent Italian entomologist. He studied a broad range of arachnid groups, including Araneidae, Acari, Ricinulei, Palpigradi, Schizomida, Opiliones, and Amblypygi. His research mainly focused on evolutionary systematics, taxonomy, and biogeography. Over the course of his career, he described 23 new genera and 367 new species belonging to 33 different arachnid families. The International Society of Arachnology's Brignoli Award is named in his honor.
