Abstract

Abstract Nematodes of the genus Auanema are interesting models for studying sex determination mechanisms because their populations consist of three sexual morphs (males, females, and hermaphrodites) and produce skewed sex ratios. Here, we introduce a new undescribed species of this genus, Auanema melissensis n. sp., together with its draft nuclear genome. This species is also trioecious and does not cross with the other described species A. rhodensis or A. freiburgensis. Similar to A. freiburgensis, A. melissensis’ maternal environment influences the hermaphrodite versus female sex determination of the offspring. The genome of A. melissensis is ~60 Mb, containing 11,040 protein-coding genes and 8.07% of repeat sequences. Using the estimated ancestral chromosomal gene content (Nigon elements), it was possible to identify putative X chromosome scaffolds.
