Remarks.

In 2007, Miller synonymised Gongylidiellum uschuaiense Simon 1902 under Neomaso patagonicus based on "holotype male from Terre de Fue [Tierra del Fuego], Argentina, 21794, in MNHN". The locality data provided by Miller is imprecise and does not enable us to confirm that this specimen was part of the type series. Furthermore, the original description presented by Simon clearly describes a female and Miller (2007) mentions examining a male holotype. We conclude that Miller did not see the specimen described by Simon and therefore the synonymy is incorrect; also because the female in Hamburg is clearly not a Neomaso based on the female genitalia lacking a scape.

Taxonomic note.

Species from the genus Gongylidiellum are found in the Old World, except for Gongylidiellum uschuaiense . It is highly likely that this species does not belong in this genus, as already indicated by Simon when he gave the species name with a “?”. Further work on Argentinian Linyphiidae is necessary before the species can be placed more accurately.

Current systematic position.
