Currently the collection has more than 32,000 lots, 600 primary types (60% of spiders, 28% of opiliones), being the third largest collection in number of lots and second in number of types in Brazil. Most lots belong to Araneae (75%), followed by opiliones (20%). The collection has a good geographic coverage for Brazil and low for other regions (300 lots from other countries in South America, 50 from Central America, 100 from North America, 200 from Europe).

The MZUSP’s arachnid collection started with material obtained by Rudolf and Herman von Ihering, Luederwaldt, Garbe, and Bicego in the late 19th and early 20th centuries. The collection was initially studied by Candido Mello-Leitão (1918), and in the 1930-1940s by Salvador Toledo-Piza, Benedito, and Helia Soares. From the 1980s onwards the collection started to be intensively studied, resulting in an addition of material and identification/description of species by Adriano Kury, Antonio Brescovit, Alexandre Bonaldo, Arno Lise, Herbert Levi, Norman Platnick, and Ricardo Pinto-da-Rocha.
