Common name: Tamesí Molly
Synonyms and Other Names: broadspotted molly

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).

Puerto Rico &
Collected in Palm Beach (Courtenay et al. 1974) and Hillsborough counties, Florida.
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.
