Tigrosa helluo, commonly known as the Wetland Giant Wolf Spider, is a species of spider belonging to the family Lycosidae, also known as wolf spiders. T. helluo was formerly known as Hogna helluo before differences between dorsal color patterns, habitat preferences, body structures, etc. were discovered. [2]
The genus Tigrosa was erected by Allen R. Brady in 2012. Prior to 1990, many medium to large wolf spiders (family Lycosidae) from North America were placed in the genus Lycosa. In 1990 it was accepted that Lycosa was a Mediterranean genus and did not occur in North America; seven species were transferred to Hogna.
