The Nonindigenous Occurrences section of the NAS species profiles has a new structure. The section is now dynamically updated from the NAS database to ensure that it contains the most current and accurate information. Occurrences are summarized in Table 1, alphabetically by state, with years of earliest and most recent observations, and the tally and names of drainages where the species was observed. The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected. References to specimens that were not obtained through sighting reports and personal communications are found through the hyperlink in the Table 1 caption or through the individual specimens linked in the collections tables.

† Populations may not be currently present.


Means of Introduction: Both occurrences are presumed to be released or escaped pets (Cardoza et al., 1993).

Status: Not established. These isolated captures do not indicate an established, breeding population (Cardoza et al., 1993).

Impact of Introduction: None since a population did not establish (Cardoza et al., 1993). C. flavomarginata preys upon snails, worms and other invertebrates (Oakland Zoo, 2003).

Remarks: Females lay clutches of 1 to 3 eggs in dry, shaded soil during March through August; incubation is 75 to 90 days (Conner and Wheeler, 1998; Oakland Zoo, 2003).
