Type species.

Ditha elegans Chamberlin, 1929.

Diagnosis.

The genus Ditha can be diagnosed by the following combination of characters: tergites with biseriate setae; carapace with more than 50 setae; trichobothria st and t more than one areolar diameter apart, and triple galea in the juvenile stage. Ditha is divided into two subgenera, Ditha (Ditha) and Ditha (Paraditha) . The subgenera Ditha Paraditha and Ditha can be differentiated based on the intercoxal tubercle and the number of accessory setae on the cheliceral palm (Beier, 1955). In Ditha , the intercoxal tubercle is strongly distinct and 10-12 accessory setae are present on the cheliceral palm, while the intercoxal tubercle is indistinct or even absent in Ditha Paraditha and only 1-2 accessory seta present on the cheliceral palm.
