ResumoespanolRossomyrmex minuchae es una hormiga esclavista endemica del sureste peninsular con tres pequenas poblaciones conocidas. Por esta circunstancia y por su particular biologia, se temia por un deterioro genetico de sus poblaciones. En este trabajo se estudio su genetica poblacional asi como su filogenia, para conocer su estado de conservacion y su posible origen. Como resultado, se obtuvo que las tres poblaciones parecen haber permanecido efectivamente aisladas por un largo periodo de tiempo, lo que ha conducido a su actual diferenciacion genetica. Ademas, aparentemente no existen evidencias de endogamia ni cuellos de botella que amenacen su supervivencia. Por otra parte, de acuerdo con la filogenia realizada, el genero Rossomyrmex seria independiente de sus hospedadoras aunque compartirian un origen asiatico. EnglishRossomyrmex minuchae is a slave-making ant endemic to the Southeastern Spain with three small populations known. For this reason and for its unique biology, a genetic impoverishment of its populations was likely. This work focuses in its population genetics as well as its phylogeny in order to know its conservation status and possible origin. As a result, the three populations seem to have remained effectively isolated for a long period of time, what seems to have driven to their present genetic differentiation. Moreover, apparently there are no evidences of inbreeding or bottlenecks threatening its survival. On the other hand, according to the phylogeny obtained the genus Rossomyrmex would be independent of their hosts despite both would share an Asian origin
