The data matrix comprised a total of 98 species representing 16 families scored for 146 characters, with all but six taken from various morphological systems; the remaining are behavioral attributes.
Ctenidae is shown to be polyphyletic as currently delimited, but the most severely questioned taxa (i.e., Acanthoctenus, Cupiennius, and Ancylometes) are indeed members of this family.
This clade is recognized as Ctenidae sensu stricto and it comprises at least five major lineages: Acantheinae, Acanthocteninae, Calocteninae, Cteninae, and Viridasiinae.

 TrekNature | Phoneutria Nigriventer Photo
These spiders belong to the family Ctenidae where Phoneutria is one of around 40 genus and the only one knowned that have a venom potent enough to be a danger to humans.
Phoneutria differs from other genus in the family Ctenidae by a thick comb of hairs on the lateral edge and ventral part of the pedipalps.
Phoneutria also differs from other ctenids by its unique warning display - the body and the two first legpair are kept vertical and then the spider rock from side to side horizontally.

Due to the fact that both species include large animals, it is believed that a single bromeliad does not have enough resources to enable two spiders to live in it.
Both species prefer to remain inside the bromeliad during the day not only because the leaves provide protection against direct sun radiation but also because the high humidity, provided by the water accumulated inside the central tank, prevents desiccation, even if the temperatures inside and outside the plant are the same.

Caloctenus Keyserling is examined and redefined to include small ground-dwelling spiders with an enhanced ventral spination beneath anterior tibiae/metatarsi -a combination of five-eight/six-seven paired-spines, pars cephalica well marked by a deep furrow, strongly convex pars thoracica, and body thickly coated with iridescent scales.
Caloctenus penicilliger Simon and C. variegatus Bertkau are transferred to Enoploctenus Simon,1897.

 Miturgidae
Being active at night, it is then that most bites occur when the animal is inadvertently pressed against the body, as the large fangs of this spider are capable of penetrating light fabrics.
Other Miturgidae spiders are also nocturnal, free ranging, cryptic and terrestrial and resemble the Lycosidae and Ctenidae.
Two other common genera, Phanotea and Griswoldia (formally Machadonia) are the most common terrestrial spiders in forested areas, hence the common name, forest floor spider.

Nevertheless, no araneologist can easily identify species of the dominant Nearctic spider family (Linyphiidae), because basic taxonomic research and manuals are lacking.
The taxonomy of widow spiders (Theridiidae: Latrodectus) and Ctenidae is similar, even though both groups inflict fatal bites.
Although the spectacular diversity of spider silks and web architectures is of obvious interest to material scientists, fewer than a dozen species in one or two closely related families have been well-studied.

Question asked: What is the most dangerous banana spider?
The name Banana Spider has been given to various, and often unrelated types of spiders, including Golden Silk Spider - Nephila clavipes, Wandering Spiders - Family Ctenidae, practically any large spider found in banana shipments, and even a few scary and fictitious hoax spiders found on the W W Web.
The most 'dangerous' banana spiders are found in Family: Ctenidae among such genera as Phoneutria, Ctenus and Cupiennus.
