Abstract

The first endophytic oviposition from the Upper Permian of the Pechora Basin (Talbeyskaya Formation, Severodvinian–Vyatkian) is described in a formal system. Paleoovoidus krassilovi sp. nov. is a linear oviposition arranged in two oppositely directed rows on a leaf of Phylladoderma arberi Zalessky, 1913; it was probably produced by an odonatan insect. Cuticle punctures that probably represent traces of feeding by small and/or young palaeodictyopteroid nymphs were previously described from Phylladoderma leaves found in the same deposits. Fossil insects remain unknown from the Talbeyskaya Formation, but fossil records of plant–insect interactions enable the reconstruction of a well-balanced insect community that included sucking phytophages (palaeodictyopteroids) and predators (odonatans).

在Phylladoderma（Peltaspermopsida：Cardiolepidaceae）的叶子上，Pechora盆地上二叠纪的昆虫内生卵产卵的首次报道。

摘要

在正式系统中描述了Pechora盆地上二叠纪的第一个内生产卵产卵（Severodvinian–Vyatkian Talbeyskaya组）。Paleoovoidus krassilovi sp。十一月 是线性卵形产卵，排列成两相对相反的方向，排列在毛竹楠的叶子（1913年）上；它可能是由odonatan昆虫产生的。早先的Phylladoderma曾描述过可能代表小和/或幼小古蝶类若虫觅食痕迹的表皮穿刺在相同的沉积物中发现叶子。化石昆虫在Talbeyskaya组中仍然是未知的，但是化石记录的植物与昆虫之间的相互作用使得能够重建一个平衡的昆虫群落，其中包括吸食性的鳞翅目动物（捕食类鳞翅类动物）和掠食性动物（odonatans）。
