What is "titanoeca"

Titanoeca is a genus of spiders that occurs mainly in Eurasia, with three species found only in North America (T. americana, T. brunnea, T. nigrella). One species (T. nivalis) has a holarctic distribution, and T. guayaquilensis is endemic to Ecuador.

The species formerly known as Titanoeca obscura was renamed to T. quadriguttata.
