The moths, Atheloca subrufella (Hulst 1887) and A. bondari, (Heinrich 1956) are species known for their economic impact on coconut production, which Brazil is the fourth largest global producer. The first record of Atheloca in Brazil was reported by Bondar in 1940, where the author registered it being A. subrufella. The studies performed by C. Heinrich in 1956 related the existence of divergence in specimens of Brazilian Atheloca suggesting the presence of morphological differences between the males of A. bondari and A. subrufella. In this study, Atheloca specimens from the five states of northeastern Brazil were used. Samples from Pernambuco state were sent to taxonomist Dr. V. O. Becker (Uiraçu Institute-BA) for identification. Male individuals from the other states were mounted for photographic documentation, highlighting the characteristics that differentiate the two species. A fragment of the cytochrome c oxidase subunit 1 gene was sequenced and then compared with that of the Atheloca spp. deposited in GenBank. An analysis was conducted to evaluate the genetic distance between A. bondari and A. subrufella. The results indicate greater interspecific (0.030–0.034) than intraspecific (0.000–0.002) genetic variation between the groups, reinforcing the hypothesis of two distinct species. A geographic distribution map and a table with the host plants were constructed based on a literature review. This study concluded that the species occurring in Brazil is A. bondari, as suggested by C. Heinrich. Atheloca bondari and A. subrufella have only been reported in plants of the family Arecaceae, but only the coconut tree (Cocos nucifera L.) is shared by the two species.

在巴西,哪种椰子蛾发生:Atheloca subrufella与Atheloca bondari(鳞翅目:Pyralidae)?

飞蛾(Atheloca subrufella)(赫尔斯特,1887年)和A. bondari(海因里希,1956年),因其对椰子生产的经济影响而闻名,巴西是全球第四大生产国。Bondar于1940年报道了巴西Atheloca的第一张唱片,作者将其注册为A. subrufella。C. Heinrich在1956年进行的研究涉及巴西Atheloca标本中存在分歧,这表明A. bondariA.subrufella的男性之间存在形态差异。在这项研究中,Atheloca使用了巴西东北部五个州的标本。来自伯南布哥州的样本已发送给分类学家VO Becker博士(UiraçuInstitute-BA)进行鉴定。来自其他州的男性个体被收集用于摄影记录,突出了区分这两个物种的特征。对细胞色素c氧化酶亚基1基因的片段进行测序,然后与Atheloca spp的片段进行比较。存放在GenBank中。进行了分析,以评估A. bondarisub.rufella之间的遗传距离。结果表明,两组之间的种间遗传差异(0.030–0.034)比种内种质(0.000–0.002)大,这增强了两个不同物种的假设。基于文献综述,构建了地理分布图和带有寄主植物的表格。这项研究得出的结论是,正如海因里希(C. Heinrich)所暗示的,在巴西发生的物种是A. bondariAtheloca bondariA.subrufella仅在槟榔科的植物中有报道,但只有椰子树(Cocos nucifera L.)是两个物种共有的。
