Distribution: Central America; from southern Honduras to western Panama, Atlantic and Pacific drainages; ( Nicaragua) Co, UI, WK, Pr, GM, KP, Es, BF, IM, To, Sa, SJ, RF, LN (Atlantic), Ch, Ne, ER, PN and Ni (Pacific); 0–680 masl; Sec, Dia, Amp. Occurrence and conservation status: Nat; DD (2020), population trend unknown. Literature: Astorqui (1975: 108, as Poecilia dovii Günther 1866 —misidentification(?); brief description, including illustrations and an identification key, and information on distribution and ecology), Bussing (1998: 219; brief description, including illustrations and an identification key, and information on distribution, with a map, and ecology), Gros & Miguel-Frithz (2010: 243; brief description, including illustrations, and information on distribution and ecology, plus indigenous science and ethnoichthyology), van den Berghe (2015: 35; listed, including an illustration and information on distribution and ecology) and Angulo (2021: 56; listed, including information on distribution). Remarks: The species Poecilia gillii , as herein considered, sensu Bussing (1998), corresponds, in part, with the molecular definition of the species Poecilia mexicana sensu Alda et al. (2013) and Bagley et al. (2015). These authors concluded that P. mexicana “have a much wider geographical distribution than previously thought” and that it is distributed from the Lake Petén Itzá drainage, Guatemala, to the río Cuango, Panama, on the Atlantic, and from the río Goascorán (El Salvador-Guatemala) to the río Bayano, Panamá, on the Pacific. The species P. gillii sensu Alda et al. (2013) and Bagley et al. (2015), is restricted to their type locality (the río Chagres, Panama) and adjacent waters between the río Parismina, Costa Rica, and the río Playón Chico, Panama ( Bagley et al. 2015). Morphological, and more inclusive molecular, studies are necessary to clarify this situation and to properly diagnose both species.
