Family Titanoecidae Lehtinen, 1967

Diagnosis. Titanoecidae are cribellate araneomorph spiders lacking tarsal trichobothria, with only a single metatarsal trichobothrium, the MAP spigots of the ALS set partially surrounded by the Pi spigot field and possessing a complex dorsal apophysis (DTA) which can be devided into a retrolateral (RLT), a median (MLT) and a prolateral (PLT) lobe on the male palpal tibia. They are distinguished from both Megadictynidae and Phyxelididae by a complex, three-lobed (not simple) DTA and in lacking paracribellar spigots on the PMS, and are further distinguished from Megadictynidae in having a divided (not entire) cribellum and from Phyxelididae in lacking any clasping modifications of the first male metatarsus (See Griswold et al. 1999; Dimitrov et al. 2017).
