Family ISODICTYIDAE Dendy, 1924
Compiler and date details
2010 - J.N.A. Hooper, Queensland Museum, Brisbane
Introduction
The family was recently resurrected by Hajdu & Lobo-Hajdu (2002) following Samaai et al.'s (1999) rigorous formal analysis on the affinities of Isodictya. The family contains eight nominal and two valid genera, Coelocarteria and sodictya, with Ichnodonax included as a junior synonym of Coelocarteria, and Cercidochela, Homoeodictya, Neoesperiopsis, Textiliforma and Valentis included in Isodictya.
Diagnosis
Mycalina with (mostly) diactinal megascleres arranged in a (plumo)reticulate skeletal architecture (niphatid- or phloeodictyid-like) and palmate isochelae.
