Records of the short-tailed whipscorpion Stenochrus portoricensis Chamberlin, 1922 (Schizomida: Hubbardiidae) from greenhouses in North Rhine-Westphalia are presented together with detailed diagnostic drawings of the species. Stenochrus portoricensis is native to southern North America and the Caribbean and is the most commonly introduced species of Schizomida in Europe. In Germany the species has only been recorded previously from Hesse. A review of all introduced schizomid records in Europe reveals that S. portoricensis is currently the only species that occupies habitats outside of greenhouses. [ABSTRACT FROM AUTHOR]

The American linyphiid spider Erigone dentosa O. Pickard-Cambridge, 1894, was found in a plant market garden in the city of Zeitz (Saxony-Anhalt).

Erigone dentosa was firstly caught by hand in February 2020, until September 12 specimens were recorded. It is unknown, how this species has reached the plant nursery. A total of 68 spider species and three harvestmen species was found, seven of them are alien species. [ABSTRACT FROM AUTHOR]
