Etymology: Poecilia: Greek, poikilos = with a lot of colours (Ref. 45335); kykesis: Name from Greek 'Kykesis' for 'a mixing', refering to the confusing mixture of homonyms,
caused by the double recognition Poecilia petenensis and Mollienesia petenensis as congeneric species.

पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 12 - 16; ऐनल सौफट रेज़: 9. This species is distinguished by the following characters: D 12-16; A 9; lateral line scales 28-29; circumpendancular scales 20; no specific body pigmentation, except for the black margined scale; in adult males, the black margins can form spots, extending the rows of spots found on the caudal fin; caudal fin with a slightly produced lower margin (Ref. 84929).
Cross section: compressed.
This species is like other species in the Poecilia latipinna complex, which occurs in shallow, brackish to freshwater coastal areas such as tidal lagoons, lakes, creeks, and pools. It is also found across a range of turbidity (clear to muddy) and substrate types (mud, sand, clay) and is sometimes associated with submerged or emergent aquatic vegetation (Ref. 125334).
