Damage from Sinoxylon anale Lesne, a woodboring beetle not previously known to be established in Brazil, was observed in young jabuticaba trees (Plinia cauliflora, Myrtaceae) in a nursery in the municipality of Laranjal Paulista, state of São Paulo. We immediately advised MAPA ("Ministério da Agricultura, Pecuária e Abastecimento") and collected samples from the nursery and from different hosts in nearby areas, to identify the specimens and investigate the dynamics of the infestation in the jabuticaba trees. Sinoxylon anale was also collected in ethanol-baited and ultraviolet-light traps and in dry branches of the native species pau-jacaré (Piptadenia gonoacantha, Fabaceae) and inga (Inga vera, Fabaceae), and the exotic pau-d'água (Dracaena fragrans, Asparagaceae) in the municipality of Piracicaba, state of São Paulo. These collections established that S. anale larvae and adults develop in dead branches of four new host plants. Taxonomic studies using morphological parameters and DNA barcoding confirmed the identification of S. anale. An illustrated key to the three Sinoxylon species now recorded in Brazil is provided, and the COI gene sequences have been made available in a public database. Sinoxylon anale probably attacked the young jabuticaba trees after they were killed by larvae of long-horned beetles (Cerambycidae). So far, S. anale has been found established only in two locations in the same area of the state of São Paulo.
Sinoxylon anale Lesne，一种以前未在巴西发现的钻木甲虫，对苗圃中的年轻树葡萄（Plinia cauliflora，桃金娘科）造成了损害。我们立即向 MAPA（“巴西农业部”）报告，并从苗圃和附近地区的不同寄主采集样本，以鉴定标本并调查树葡萄上的感染动态。还在乙醇诱饵和紫外线陷阱以及本地物种 pau-jacaré（Piptadenia gonoacantha，豆科）和 Inga（Inga vera，豆科）的干树枝以及 Piracicaba 市的外来 pau-d'água（Dracaena fragrans，天门冬科）中收集了 Sinoxylon anale。这些收集结果表明，S. anale 的幼虫和成虫在四种新寄主植物的死枝中发育。使用形态参数和 DNA 条形码进行的分类学研究证实了 S. anale 的鉴定。提供了三种现已在巴西记录的 Sinoxylon 物种的插图钥匙，并且 COI 基因序列已在公共数据库中提供。S. anale 可能在被长角甲虫（Cerambycidae）幼虫杀死后袭击了年轻的树葡萄。到目前为止，S. anale 仅在圣保罗州同一地区的两个地点发现。
