[3] This is one of a small number of invertebrates endemic to the karst caves of Bexar County that were federally listed as endangered species in the year 2000.

[5][2] C. madla can be distinguished from Cicurina species occurring in the same area by its TI index, as well as by genetic data and the structure of the female spermatheca or the male palpal bulb.

[7] A study of Cicurina spiders from Texas caves in 2018 concluded that the sole known specimen of C. venii belongs to the same species as C. madla, and synonymized them.

[1] The Bexar County karst cave invertebrates are troglobites, species that spend their entire lives in subterranean environments.

[3] In August 2012, a spider assigned to this species was found in a 6-foot-deep natural hole in Northwest San Antonio, halting completion of a $15-million highway underpass.
