Among birds, T yrannidae comprises one of the most diverse and species‐rich families. Although cytogenetic data have shown interesting results in this family, such as variations in the macrochromosome morphology and diploid number, only a few species have had their karyotypes described. In the present study, we report the characterization of the karyotype of E laenia spectabilis ( P asseriformes, T yrannidae) by means of classical and molecular cytogenetics. The results show that syntenic groups of G allus gallus ( GGA ) were conserved, except GGA1 and GGA4 , which were divided into two different pairs each. However, the results obtained with L eucopternis albicollis probes revealed the occurrence of inversions in segments homologous to GGA1q , similar to those observed in other P asserifomes ( T urdus ), and one inversion in GGA1p . These results suggest that the centric fission in GGA1 , as well as the inversions observed in segments homologous to GGA1q , appeared in the early history of P asseriformes because they could be detected in O scine and S uboscine species. © 2015 The Linnean Society of London, Biological Journal of the Linnean Society , 2015, 115 , 391–398.
