Abstract Anthracoceros coronatus (Bucerotiformes: Bucerotidae) has been listed in near threatened category in the IUCN Red List of Threatened Species, due to population decline. Mitochondrial genome (mitogenome) sequence is informative and very useful for systematics and conservation biology studies. In this study, we first determined and characterized the complete mitogenome of A. coronatus using next-generation sequencing platform. The complete mitogenome of A. coronatus was 17,214 bp in length, with an AT ratio of 52.8%. It contained the typical structure of 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA genes and a non-coding control region or D-loop region, with an identical gene order to that of most other vertebrates. The complete mitogenome sequence of A. coronatus would not only provide additional molecular markers of choice for detecting illegal poaching and trafficking of this bird species, but also would contribute to phylogenomic study of hornbill birds. Keywords Anthracoceros coronatus · Mitochondrial genome · Next generation sequencing Anthracoceros coronatus, commonly called as Malabar Pied Hornbill, belongs to the genus Anthracoceros of the Rong Li and Yanyan Chen have contributed equally to this work. * Shanyuan Chen [email protected] 1

family Bucerotidae. This species distributes mainly in tropical deciduous forests of central and southern India and Sri Lanka. However, illegal poaching and habitat destruction have caused dramatic population decline during the past decades (Ripley 1982; Zacharias and Gaston 1999). This species was listed in Least Concern (LC) category from 1988 to 2000, but later has been listed in Near Threatened (NT) category since 2004 in the IUCN Red List of Threatened Species. In China, this species has been regionally considered as the Class II national protected species (Que et al. 2010). Despite of being classified as a protected species in nature reserves, unfortunately, effective protection measures remain unavailable because little is so far known about genetic background of this species. As a result, it is still a great challenge for us to efficiently protect Anthracoceros coronatus resource from continuing decline. It is well recognized that mitochondrial genome (mitogenome) sequence is informative and very useful for systematics and conservation biology studies. In particular, for a protected animal species, molecular markers generated from mitogenome sequence have proven useful for conservation studies and practices (Gal
