Some largely morphology-based
phylogenetic studies that included the three families assigned to the Eresoidea supported their
monophyly, with the internal structure of the clade being as shown below. }} Eresoidea was placed as basal in the
Entelegynae, with its precise position relative to the
Palpimanoidea, also basal, varying. In 2015,
Jonathan A. Coddington summarized this as a trichotomy: }} Another summary phylogeny groups Eresoidea and Palpimanoidea into a single clade, sister to the "canoe tapetum clade" holding the remaining entelegynes. Other studies, particularly those using genetic data, have presented different views. A 2010 study of the phylogeny of entelegyne spiders separated Eresidae from Oecobiidae and Hersiliidae, placing the latter two in a superfamily Oecobioidea. In 2014, a
cladogram was presented in which Eresoidea is similarly
paraphyletic (shading marks Eresoidea families): }} A 2014 study based on a larger portion of the spider
genome than any previous study also separates the Eresidae and the Oecobiidae (Hersiliidae was not included) (eresoid families are again shaded): }} A 2017 study also did not support Eresoidea, agreeing with earlier studies in placing Eresidae away from Hersiliidae and Oecobiidae, which were grouped as Oecobioidae. == References ==
