Poltys and the genera Cyphalonotus, Homalopoltys, Ideocaira, Kaira, Micropoltys and Pycnacantha have historically been considered members of the tribe Poltyini. There is little published information on most members of the group and their potential relationships in the context of recent advances in araneid systematics. Information is sought on possible relatives of Poltys. All araneid members of the group except Pycnacantha were added to the data matrix compiled by Scharff & Coddington (1997), which already contained Kaira. Homalopoltys was found to be a tetragnathid when males were identified and was not considered further. The full data matrix of 74 taxa and 82 characters was run in PAUP* and NONA. The resulting placement of Poltys was not well supported but it frequently occurred in association with members of a slightly modified version of the ‘Hypsosinga clade’ of Scharff & Coddington, including Kaira. Cyphalonotus may be placed close to Araneus and Ideocaira may also belong in the same area of the araneines. Micropoltys may belong in the sister clade to these two.
