Abstract Background Stethorini are specialized mite predators in the family Coccinellidae, which are small with black body and brown or yellow colored appendages. This study aimed to survey species of Stethorini associated with phytophagous mites of South India and their prey range. Results Eight species of Stethorini, viz., Parastethorus sp. Stethorus (Allostethorus) forficatus, S. (A.) pauperculus, S. (A.) tetranychi, S. (A.) sp., S. keralicus, S. (S.) rani and S. (S.) sp., each associated with distinct species of mite were identified in this study and part of mitochondrial cytochrome c oxidase subunit I sequences of seven of these species are provided. Barcode gap analysis and distance summary analysis in the BOLD system as well as phylogenetic analysis of these seven species were given. Conclusions This study revealed the species of Stethorini in South India along with their prey range and associated plants. As all the species look similar with black body and yellow appendages, DNA barcodes generated can be used as an effective bio-identification tool for this group.
