Abstract

Myxia belinda gen. et sp. nov. is established for a new taxon of Cixiidae in the tribe Oecleini collected from palms in Costa Rica. The new taxon was discovered while surveying palms for potential phytoplasma vectors. Placement in a new genus is supported by a 1,383 bp sequence of 18S that differs by 2.77% from Haplaxius, 5.20% from Myndus taffini, and 2.80% from Nymphomyndus caribbea. Intrageneric variation for 18S was found to be approximately 0.5% to 0.6% within Haplaxius. Generic level differences within the Oecleini for COI ranged from 15% to 17% with the novel taxon differing by about 16% from other genera. The new genus is most similar in appearance to Haplaxius but possesses striking sexual dimorphism, and the aedeagus is only partially surrounded by the phallobase (versus entirely enveloped in Haplaxius). The discovery of a novel taxon of cixiid on palms that is similar to Haplaxius is important because of the role that Haplaxius crudus plays in phytoplasma transmission in palm agro- and natural ecosystems.

摘要

Myxia belinda 属及种为新种，是在哥斯达黎加从棕榈树上采集到的 Oecleini 族绵蚜科的一个新分类单元。这个新分类单元是在对棕榈树进行潜在植原体传播媒介调查时发现的。将其置于一个新属得到了 18S 的 1383 碱基对序列的支持，该序列与 Haplaxius 的差异为 2.77%，与 Myndus taffini 的差异为 5.20%，与 Nymphomyndus caribbea 的差异为 2.80%。在 Haplaxius 属内，18S 的种内变异约为 0.5%至 0.6%。Oecleini 族内 COI 的属级差异范围为 15%至 17%，新分类单元与其他属的差异约为 16%。新属在外观上与 Haplaxius 最相似，但具有明显的两性异形，且阳茎仅部分被阳茎基包围（而在 Haplaxius 中则完全被包围）。在棕榈树上发现一个与 Haplaxius 相似的绵蚜科新分类单元很重要，因为 Haplaxius crudus 在棕榈农业和自然生态系统的植原体传播中发挥着作用。
