Resumo: 	The objective of this study was to analyze the maternal-embryonic relationship in eight hybrids Poeciliopsis monacha-lucida. Two natural hybrids (MLVII and MLVIII) collected in Mexico, and in a repertory of six hybrids produced by artificial insemination (A1, A4, B1, B2, E1, and E2) were analyzed. Dry weight of mature eggs and of embryos was significantly different among hybrids. All hybrids but B1 and E2 exhibited superfetation and lecithotrophy. This result showed that the association between superfetation and lecithotrophy were not restricted to P. monacha.
