Chromosome-level genome assembly of the snakefly Mongoloraphidia duomilia (Raphidioptera: Raphidiidae)
摘要
Raphidioptera (snakeflies) are a holometabolan order with the least species diversity but play a pivotal role in understanding the origin of complete metamorphosis. Here, we provide an annotated, chromosome-level reference genome assembly for an Asian endemic snakefly Mongoloraphidia duomilia (Yang, 1998) of the family Raphidiidae, assembled using PacBio HiFi and Hi-C data from female specimens. The resulting assembly is 653.56 Mb, of which 97.90% is anchored into 13 chromosomes. The scaffold N50 is 53.50 Mb, and BUSCO completeness is 97.80%. Repetitive elements comprise 64.31% of the genome (366.04 Mb). We identified 599 noncoding RNAs and predicted 11,141 protein-coding genes in the genome (97.70% BUSCO completeness). The new snakefly genome will facilitate comparison of genome architecture across Neuropterida and Holometabola and shed light on the ecological and evolutionary transitions between Neuropterida and Coleopterida.
