Males of C. pedregal sp. nov. are distinguished from those of the other species of the genus by the palp with vRTA2 bifid with one branch short and stout and the other almost as long as dRTA, with an aculeus-like projection at tip and by the tegulum proximally swollen (Fig. 81). Females are unknown.
