摘要

寄生昆虫是寄生在蚂蚁(膜翅目)、蛾幼虫(鳞翅目)和甲虫幼虫(鞘翅目)等昆虫群中的一个属。本属的特点是柱头圆柱形,近球形到球形的可育头具浸没的包皮,透明的,多裂的子囊孢子和不规则分枝的分生孢子,具有瓶形的花梗和圆柱形到纺锤形的分生孢子。Paraisaria是全球分布,主要居住在热带和亚热带地区;然而,它也表现出对温带气候的适应性。本文介绍了两个新种,并报道了一种无性形态,对其进行了详细的描述、图解和分子系统发育分析。形态学检查揭示了新种与先前描述的分类群之间的明显区别。多位点系统发育分析(LSU, ITS, SSU, tef-1α, rpb1和rpb2)证实了它们的独特性,为该属的多样性和进化动力学提供了新的见解。

Two new species and one asexual morph record of Paraisaria (Ophiocordycipitaceae, Hypocreales) from China.

Paraisaria is a genus within Ophiocordycipitaceae, primarily parasitising insect groups such as ants (Hymenoptera), moth larvae (Lepidoptera) and beetle larvae (Coleoptera). The genus is characterised by cylindrical stipes, subglobose to globose fertile heads with immersed perithecia, hyaline, multi-septate ascospores and irregularly branched conidiophores with flask-shaped phialides and cylindrical to fusiform conidia. Paraisaria is globally distributed, primarily inhabiting tropical and subtropical locations; however, it has also demonstrated adaptability to temperate climates. This study introduces two novel species and reports one asexual morph of Paraisaria from China, providing detailed descriptions, illustrations and molecular phylogenetic analyses. Morphological examination reveals clear distinctions between the new species and previously described taxa. Multi-locus phylogenetic analyses (LSU, ITS, SSU, tef-1α, rpb1 and rpb2) corroborate their uniqueness, offering new insights into the diversity and evolutionary dynamics of the genus.
