Diagnosis. Males are readily diagnosable from R. griswoldi and R. pilar by having the basal part of RTA with a rounded anterior margin (Figs. 32, 34). Females can be distinguished from R. pilar by the copulatory ducts with tips directed laterally (Figs. 38, 39), from R. griswoldi by having the hoods covering less than half the epigynum plate length (Figs. 36, 37), from R. golondrina by having the hoods with mesal margin straight (Figs. 36, 37) and from R. sudcaliforniensis and R. naranjensis by having the spurs not exceeding the epigastric furrow in ventral view (Fig. 37).
Etymology. The specific name is a noun in apposition and refers to the extant ethnic native American group named “ Cochimí ” of the Baja California Peninsula.

One female was captured and kept under observation at the laboratory, where it made four egg sacs over a period of 100 days; gestation time of the eggs was around 45 days. When we fed the female with prey, such as Tenebrio molitor larvae, the spider ran to it, bit it, and carried it to site near the shelter to feed on it later. In the case of smaller and faster prey, such as ants, the spider moved around it and immobilized it with silk thread before attempting to bite it. After emergence, juveniles wove a simple sheet-web, and after the second molt (30 – 45 days after birth), they started to weave the characteristic funnel-shape retreat. Juveniles also immobilize ants with silk thread before biting.
