5/31/2023 0 Comments Brazilian wandering spiderP. nigriventer is known to hide in dark and moist places in or near human dwellings. During the day they hide inside termite mounds, under fallen logs and rocks, in banana plants (hence the "banana spider" nickname), and bromeliads. Wandering spiders are so-called because they wander the jungle floor at night, rather than residing in a lair or maintaining a web.

During the defensive display the body is lifted up into an erect position, the first two pairs of legs are lifted high (revealing the conspicuous black/light-banded pattern on the leg underside), while the spider sways from side to side with hind legs in a cocked position. The characteristic defensive posture with frontal legs held high is an especially good indicator to confirm a specimen is Phoneutria, especially alongside correct colour patterns. Other features are the strong ventral marking on the underside of the legs with contrasting dark mid-segments and lighter joints, and the pattern on the ventral (underside) of the abdomen with several rows of black dots, or an overall reddish colour. The presence of a dark linear stripe or stripes on the frontal (dorsal) palps and presence of a single thin black line running anterior-posterior along the dorsal carapace may help identify Phoneutria. Additionally, some Phoneutria species lack red hairs on the chelicerae, making it an unreliable identification feature. chiapanensis also has bright red hairs on the chelicerae. Phoneutria are easily confused with several other non-medically significant ctenids, especially Cupiennius, in which the recently described C. The genus is distinguished from other related genera such as Ctenus by the presence of dense prolateral scopulae (a dense brush of fine hairs) on the pedipalp tibiae and tarsi in both sexes. While some other araneomorph spiders have a longer leg span, the largest Phoneutria species have the longest body and the greatest body weight in this group. Their body length ranges from 17 to 48 mm ( 43⁄ 64 to 1 + 57⁄ 64 in). The spiders in the genus can grow to have a leg span of 13 to 18 cm (5 to 7 in). Other English names include armed spiders ( armadeiras in Brazilian Portuguese) and banana spiders (a name shared with several others). Members of the genus are commonly referred to as Brazilian wandering spiders. They are mainly found in northern South America, with one species in Central America. Phoneutria is a genus of spiders in the family Ctenidae.
