Pseudotapinopa is a monotypic genus of spiders in the family Linyphiidae containing the single species, Pseudotapinopa cotopaxi.
Pseudotapinopa cotopaxi has only been recorded from Ecuador.
The species is only known from two males that were beaten from a bush in 1979. It is yellowish, with a body length of 3.5-4.0 mm.
The genus is named for its apparent relationship to genus Tapinopa <small>Westring, 1851</small>, with the prefix "pseudo-" "false". The species name is derived from the place of collection of the holotype near the base of volcano Cotopaxi in Ecuador.
