Blindsnakes of infraoder Scolecophidia (order Squamata) are the most basal group of extant snakes, comprising of more than 450 species with ecological and morphological features highly specialized to underground living. The Brahminy blindsnake, Indotyphlops braminus, is the only known obligate parthenogenetic species of snakes. Although the origin of I. braminus is thought to be South Asia, this snake has attracted worldwide attention as an alien species, as it has been introduced to all continents except Antarctica. In this study, we present the first draft genome assembly and annotation of I. braminus. We generated approximately 480 Gbp of sequencing data and produced a draft genome with a total length of 1.86 Gbp and N50 scaffold size of 1.25 Mbp containing 89.3% of orthologs conserved in Sauropsida. We also identified 0.98 Gbp (52.82%) of repetitive genome sequences and a total of 23,560 protein-coding genes. The first draft genome of I. braminus will facilitate further study of snake evolution as well as help to understand the emergence mechanism of parthenogenetic vertebrates.
