ABSTRACT Noyesaphytis Polaszek & Woolley gen. nov. (type species Noyesaphytis lasallei Polaszek & Woolley sp. n. ) is described from Berenty, Tuléar, Madagascar. The genus differs from its closest relatives primarily in the structure of the female antenna, which has a single, elongate flagellum preceded by four anelli, the largest of which could be interpreted as a single anelliform funicle. This type of antenna is unknown in other Aphytini, but approaches the condition found in many Signiphoridae. Noyesaphytis possesses a character state that was until now thought to be an autapomorphy of Azotidae (sole genus Ablerus), being the groove in front of the propodeal spiracle. A second putative autapomorphy shared by Azotidae and Signiphoridae, and also Noyesaphytis, is the presence of anterior projections on the metasomal sterna. However, in Azotidae and Signiphoridae these are narrow, whereas as they are broader in Noyesaphytis. The form of the wing is consistent with Aphytini, although lacking a linea calva. The presumed male of Noyesaphytis lasallei has an antennal structure completely unknown in Aphelinidae, with a 1-segmented clava preceded by an extremely elongate single funicle, and four anelli. Differences between the female and male are discussed, some of which could indicate that the male might eventually be shown to belong to a different species, although the species are undoubtedly congeneric, despite the striking difference in antennal structure which is common in Aphelinidae. The male genitalia also suggest Aphytini. Based on a phylogenetic analysis of 50 morphological characters, we provisionally place Noyesaphytis in Aphytini pending the results of a forthcoming phylogenomic analysis. The new genus is named for its collector, John Noyes (NHM, London), and the new species is named after the late John La Salle. http://www.zoobank.org/urn:lsid:zoobank.org:pub:6EE6F35C-32A4-4E91-AE39-5E2C173E58BF

Noyesaphytis (Chalcidoidea: Aphelinidae) – 来自马达加斯加的一个不寻常的新属,以及基于形态学对 Aphelininae 分类的重新评估

摘要 Noyesaphytis Polaszek & Woolley gen。十一月 (模式种 Noyesaphytis lasallei Polaszek & Woolley sp. n.)描述于马达加斯加图莱尔的贝伦蒂。该属与其近亲的主要区别在于雌性触角的结构,雌性触角有一个细长的鞭毛,前面有四个 anelli,其中最大的一个可以解释为单个 anelliform 穗。这种类型的天线在其他 Aphytini 中是未知的,但接近许多 Signiphoridae 中发现的情况。Noyesaphytis 具有的特征状态直到现在被认为是 Azotidae(唯一属 Ablerus)的自体变形,是前体气孔前面的凹槽。Azotidae 和 Signiphoridae 以及 Noyesaphytis 共有的第二个假定的自体变形是后体胸骨上存在前部突起。然而,在 Azotidae 和 Signiphoridae 中这些是狭窄的,而在 Noyesaphytis 中它们更宽。机翼的形状与 Aphytini 一致,但缺少 linea calva。Noyesaphytis lasallei 的推测雄性具有在 Aphelinidae 中完全未知的触角结构,有一个 1 节的棒状体,前面有一个极其细长的单根,和四个 anelli。讨论了雌性和雄性之间的差异,其中一些可能表明雄性最终可能会被证明属于不同的物种,尽管该物种无疑是同类的,尽管在 Aphelinidae 中常见的触角结构存在显着差异。男性生殖器也暗示 Aphytini。基于对 50 个形态特征的系统发育分析,我们暂时将 Noyesaphytis 放在 Aphytini 中,等待即将到来的系统发育分析结果。新属以其收藏家 John Noyes(NHM,伦敦)命名,新种以已故的 John La Salle 命名。http://www.zoobank.org/urn:lsid:zoobank.org:pub:6EE6F35C-32A4-4E91-AE39-5E2C173E58BF
