Within the Meliponini, a widely distributed group of stingless bees, Melipona rufiventris has been considered as a single, cohesive species. Recently, analysis of morphological characters led to the splitting of this species into two species, M. mondury and M. rufiventris. The former occurs in the Atlantic Rain Forest ranging from Santa Catarina to Bahia States, while the latter is found in other parts of Brazil. We used PCR + RFLP to identify genetic marker patterns of the mtDNA between these species. Nine mtDNA regions were amplified and digested with four restriction enzymes (EcoRI, EcoRV, HindIII, and HinfI). Six species-specific restriction sites were identified for M. mondury and M. rufiventris with all enzymes, except for HindIII. The molecular data agree with the morphological classification.
在无刺蜂广泛分布的Meliponini族中,红腹无刺蜂(Melipona rufiventris)一直被视为一个单一的、有凝聚力的物种。最近,对形态特征的分析导致该物种被分为两个物种,即蒙杜里无刺蜂(M. mondury)和红腹无刺蜂(M. rufiventris)。前者分布于从圣卡塔琳娜州到巴伊亚州的大西洋雨林地区,而后者则在巴西的其他地区被发现。我们使用聚合酶链反应+限制性片段长度多态性(PCR + RFLP)来鉴定这些物种之间线粒体DNA(mtDNA)的遗传标记模式。扩增了九个mtDNA区域,并用四种限制性内切酶(EcoRI、EcoRV、HindIII和HinfI)进行消化。除了HindIII之外,用所有酶都为蒙杜里无刺蜂和红腹无刺蜂鉴定出了六个物种特异性限制性位点。分子数据与形态学分类结果一致。
