Abstract This article presents a detailed description of insect trace fossils found in the megaflora of the Gzhelian-Asselian of the Bajo de Veliz. Plant-insect interactions are analyzed on 212 specimens of leaves from this flora, characterized by glossopterid (Gangamopteris, Euryphyllum, Glossopteris), cordaitales, sphenophytes, pteridosperms, lycophytes, conifers and seeds. Marginal feeding, surface and oviposition traces and galling predominate, as compared to the poor representation of piercing and sucking traces. Necrotic tissue was identified on leaves of the genera Euryphyllum, Gangamopteris, Glossopteris and bipinnate fronds of Botrychiopsis, suggesting that damage was produced while the plants were alive. The first reported evidence of galling for Botrychiopsis and piercings traces in Gangamopteris leaves for Gondwana are described.

Bajo de Veliz 组（Gzhelian - Asselian）化石植物群中的植物-昆虫相互作用：阿根廷圣路易斯

摘要 本文详细描述了在 Bajo de Veliz 的 Gzhelian-Asselian 大型植物群中发现的昆虫痕迹化石。对来自该植物群的 212 片叶子标本进行了植物-昆虫相互作用分析，这些标本的特征为舌翅目（Gangamopteris、Euryphyllum、Glossopteris）、cordaitales、sphenophytes、pteridosperms、lycophytes、针叶树和种子。与刺破和吮吸痕迹的不良表现相比，边缘摄食、表面和产卵痕迹以及咬伤占主导地位。在 Euryphyllum、Gangamopteris、Glossopteris 和 Botrychiopsis 的双羽状叶上鉴定出坏死组织，表明在植物存活时产生了损伤。描述了 Gondwana 的 Gangamopteris 叶子中 Botrychiopsis 和穿孔痕迹的第一个报告证据。
