Abstract

This article focuses on the phylogenetic analysis and taxonomic revision of the Paduniella andamanensis species group within the family Psychomyiidae (order Trichoptera), based on newly sequenced mitochondrial genomes. The study identified four novel mitochondrial gene rearrangement patterns in Psychomyiidae, including a unique tandem duplication of tRNA genes in Lype sagittalis and a complex rearrangement involving protein-coding genes and tRNAs in the "andamanensis" group. Phylogenetic analyses strongly supported the monophyly of this group, with genetic distances comparable to those between established genera, leading to the proposal of a new genus, Paduniellodes gen. nov., distinguished by both molecular synapomorphies and unique male genital morphology. This work enhances understanding of mitochondrial genome evolution in Psychomyiidae and provides a molecular and morphological basis for refining genus-level taxonomy within the family.
