In most of the examined lower araneomorphs--some 20 families of hypochiloids, austrochiloids, and classical Haplogynae (including the cribellate family Filistatidae)--there is no evidence of cylindrical gland spigots. Only in the Leptonetidae and Telemidae do females have a spigot type, on both the posterior median and posterior lateral spinnerets, that is not also present in males, and that may therefore serve cylindrical glands. Cylindrical glands seem otherwise to be synapomorphic for a large group of about 70 higher araneomorph families corresponding roughly to the classical concept of Entelegynae (but including those palpimanoid and orbicularian taxa with haplogyne females). A data matrix including 67 characters for 35 haplogyne and eight related genera, belonging to 36 families, is presented and analyzed. The results suggest that the classical Haplogynae form a monophyletic group but that the superfamily Scytodoidea is paraphyletic. Paracribellar spigots, previously reported only on the posterior median spinnerets, apparently occur also on the posterior lateral spinnerets of austrochilids and filistatids. The family Loxoscelidae is placed as a junior synonym of Sicariidae.} }
