Identification and Transcriptome Resource of the Mite Orthogalumna cf. terebrantis (Acari: Galumnidae) in China

The genus Orthogalumna (Oribatida: Galumnidae) has been recognized for its phytophagous associations with aquatic plants, particularly its potential role in the biocontrol of the invasive weed Water hyacinth (Eichhornia crassipes). Despite its ecological significance, this genus remains poorly studied in terms of its micromorphological architecture, phylogenetics, and genomic resources. In this study, we report Orthogalumna cf. terebrantis from China, providing the first comprehensive characterization of an Orthogalumna species by integrating morphology, phylogeny, and transcriptomics. This record represents the first documented occurrence of O. cf. terebrantis in China, pending confirmation by voucher-based morphological comparison and molecular data. This work provides critical microstructural evidence to complement traditional morphological identification and establishes a foundational molecular dataset for future studies on the systematics, comparative genomics, and environmental adaptation of oribatid mites.
