The discovery of a second gynogenetic, triploid "species" in the genus Poeciliopsis is reported. This all-female form is part of a five-fish hybrid complex from the Rio Fuerte of northwestern Mexico. The complex consists of two bisexual species, P. monacha and P. lucida, and three unisexual derivatives, two of which are triploid and one of which is diploid. The 2n unisexual approximates 1n of P. monacha and 1n of P. lucida. During oogenesis the paternally derived P. lucida chromosomes are lost… Expand
