ionidae in their distinctive male pedipalp and simple epigynal structure. Another dis- tinctive character is the shape of the en- dites. Discussion. Justification for the proposal of a new subfamily has been outlined in Reclassification of the Micariinae, p. 164. From the North and Central American representatives of this subfamily, it appears that Castianeira is a large, generalized group and that the other genera are specialized groups derived from Castianeira. The re- lationships of the genera in this study (see Phijlogenetic Relationships of the Genera, p. 167) are summarized in Diagram 1. Key to North and Central American Genera of CASTiANEmiNAE la. lb.
