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.

Poecilia latipunctata Meek, 1904

Common name: Tamesí Molly

Synonyms and Other Names: broadspotted molly

Taxonomy: available through www.itis.govITIS logo

Identification: Tamesi mollies can be distinguished from other co-occurring species of Poecilia by the absence of two cephalic pores, counts of scales around the caudal peduncle, and color patterns (Miller 1983).

Size: to 50 mm SL (Miller et al. 2005).

Native Range: Tamaulipas, Mexico: headwaters of the Rio Tamesi (Miller et al. 2005; Tobler and Schlupp 2009).

Ecology: Occurs in clear, flowing reaches of water containing abundant aquatic vegetation over gravel or mud substrates. Primarily a benthic feeder, consuming organic matter, detritus, and associated algae and diatoms (Miller et al. 2005; Tobler and Schlupp 2009).

Means of Introduction: Aquarium release or escape from tropical fish farms (Courtenay et al. 1974).

Status: Failed introduction: this species has not been collected since 1974.

Impact of Introduction: Unknown, but likely none because of failure to establish.

Remarks: This species is considered endangered throughout its native range (Jelks et al. 2008; Tobler and Schlupp 2009). The Tamesi molly was recently recognized as a third reproductive host species for the unisexual gynogenetic Amazon molly (P. formosa), an all-female species that requires sperm from another species to stimulate egg/zygote development (Niemeitz et al. 2002).

Although originally classified as part of the shortfin molly (P. sphenops) group based on morphology (Miller 1983), both behavioral (Niemeitz et al. 2002) and genetic (Shartl et al. 1995; Ptacek and Breden 1998) evidence suggest that Tamesi mollies are part of the sailfin molly (P. latipinna) species group.

Voucher specimens: UF 138407.
