Based on the results of the present work, <i>Metaxyphloeus</i>, as currently composed, is hypothesized as a monophyletic assemblage of rostrate laemophloeids, whose definition is adjusted hereby to include two previously unknown, earliest diverging lineages. A taxonomic treatment is provided for all known species of the genus, which are diagnosed and illustrated in fine detail, including the mouthparts and genital structures. In addition, three further species are proposed as new: <i>M. brevirostris</i> <b>sp. nov.</b>, <i>M</i>. <i>dorsocapillatus</i> <b>sp. nov.,</b> and <i>M</i>. <i>homalirhinoides</i> <b>sp. nov.</b> Biological information constitutes rare direct evidence for mycophagy among members of <i>Metaxyphloeus</i>, which may also serve as vectors for the dispersion of fungal conidia and spores (endozoochory).

In Australia, a local <i>Plutella</i> known as <i>P. australiana</i> is almost morphologically indistinguishable from <i>P. xylostella</i>. Therefore, we developed a PCR–restriction fragment length polymorphism (PCR–RFLP) assay targeting the mitochondrial COI gene to differentiate the two species. COI amplicons were digested with <i>BfaI</i>, producing two fragments (~490 and ~270 bp) for <i>P. australiana</i>, whereas <i>P. xylostella</i> remained undigested (~658 bp). In total, 71 and 15 COI sequences were generated for <i>P. xylostella</i> and <i>P. australiana</i>, respectively. We found seven unique haplotypes for <i>P. xylostella</i> and two unique haplotypes for <i>P. australiana</i>. In all cases, <i>P. australiana</i> samples were consistently digested, whereas <i>P. xylostella</i> samples remained undigested. Our assay therefore produced consistent, species-specific banding patterns across multiple individuals. This provides a simple, rapid, reliable and cost-effective method for distinguishing these cryptic species without having to sequence COI. This will aid experimental and survey work where the cryptic <i>Plutella</i> species need to be identified to provide information on their distribution, host use and pest impact.</p>","PeriodicalId":8574,"journal":{"name":"Austral Entomology","volume":"65 2","pages":""},"PeriodicalIF":1.1,"publicationDate":"2026-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/aen.70079","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148065701","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
