The Gloom Widow is an enemy added to the original Final Fantasy starting with the Dawn of Souls version, based on the monster from Final Fantasy V. This enemy appears in all bonus dungeons, and is only slightly weaker than the Black Widow enemies Attack-wise. They may inflict Venom with their physical attacks, which may be a problem when entering Earthgift Shrine immediately after facing Lich.
Latrodectus is a genus of spider in the family Theridiidae, many of which are commonly known as widow spiders. Individual species vary widely in size, but in most cases the females are dark and identifiable by reddish hourglass markings on the abdomen. The spiders' venomous bite is considered particularly dangerous because of the neurotoxin latrotoxin, which causes the condition latrodectism, both named for the genus. The female black widow has unusually large venom glands and her bite is particularly harmful to humans.
