This species is known from the Atlantic Rainforest of Brazil and surrounding areas of Argentina.




The sexes of Darditilla bejaranoi are associated based on a mating pair found in the MNRJ. Additionally, M.A. Fritz collected males and females in the same locality twice in Argentina. The male and female are similar in size and geographical distribution.
Females vary in mesosomal coloration, with some specimens having only a small dark brown patch on the pronotal dorsum and others having the mesosomal dorsum and pleurae extensively darkened. The setal spots of T2 also vary slightly in shape, from perfectly circular to transversely ovate. In Casal’s key (1968a[1]) specimens with transversely ovate setal spots will run to couplet 25, where they can be separated from Darditilla bachmanni Casal, 1968 and Darditilla nelidae Casal, 1968 by the entirely black fringe of T1 (T1 with extensive white setae in Darditilla bachmanni and Darditilla nelidae) and geographical distribution (Darditilla bachmanni from Bolivian Amazon and Darditilla nelidae from central Argentina).
