Issue
The genera Lebiasina and Piabucina are separated mainly by the presence of an adipose fin in Piabucina vs. absence in Lebiasina. Allocation of species to one or another genus may vary between authors. Piabucina is maintained here pending a taxonomic revision of the subfamily Lebiasininae (Sven Kullander, pers. comm.). In young specimens this species has a series of dark spots across the body similar to those of L. multimaculata, suggesting a possible relationship, but the spots become less distinct in the adult, those anterior fading and some posterior joining to form bars on P. astrigata. In addition multimaculata has rows of red spots on the scales whereas on astrigata the spots are orange. All specimens of this species examined have an adipose fin.
