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.

Ecology: Similar to parental species.

Means of Introduction: Likely aquarium release or escape from tropical fish farms.

Status: Unknown (but likely failed) in most locations. Shafland et al. (2008) do not mention this as a permanently established species in Florida.

Impact of Introduction: Unknown.

Remarks: There are many hybrid varieties of several different Poecilia species (including P. latipinna, P. mexicana, P. sphenops, and P. velifera) that are collectively known as 'black mollies'. Also, P. latipinna produces semi-melanistic individuals in its native range.

No voucher specimens exist.
