Abstract

First record of the genus Helius-long-rostrum cranefly from Maestrazgo Basin (eastern Spain, Iberian Penisula) is documented. Two new fossil species of the genus Helius are described from Cretaceous Spanish amber and compared with other species of the genus known from fossil record with particular references to these known from Cretaceous period. Helius turolensis sp. nov. is described from San Just amber (Lower Cretaceous, upper Albian) Maestrazgo Basin, eastern Spain, and Helius hispanicus sp. nov. is described from Álava amber (Lower Cretaceous, upper Albian), Basque-Cantabrian Basin, northern Spain. The specific body morphology of representatives of the genus Helius preserved in Spanish amber was discussed in relation to the environmental conditions of the Maestrazgo Basin and Basque-Cantabrian Basin in Cretaceous.

摘要

首次记录了来自马埃斯特雷萨戈盆地（西班牙东部，伊比利亚半岛）的长喙天牛属（Helius）。本文描述了来自西班牙白垩纪琥珀的长喙天牛属的两个新化石种，并与化石记录中已知的其他种进行了比较，特别是与白垩纪时期已知的种进行了比较。新种 Helius turolensis sp. nov. 来自西班牙马埃斯特雷萨戈盆地的圣胡斯托琥珀（下白垩统，上阿尔布阶），而新种 Helius hispanicus sp. nov. 则来自西班牙北部的巴斯克-坎塔布连盆地的阿瓦拉琥珀（下白垩统，上阿尔布阶）。讨论了保存在西班牙琥珀中的长喙天牛属代表的特殊身体形态与白垩纪马埃斯特雷萨戈盆地和巴斯克-坎塔布连盆地的环境条件之间的关系。
