摘要

本文描述并展示了来自白垩纪中期克钦邦琥珀中的一种新的半水栖虫属--Cretamesovelia pellai gen.这一新类群是缅甸北部 Noije Bum 山沉积物中记录的第二个介壳虫属。该分类群与最近描述的 Myanmarvelia 属一起，进一步揭示了过去半水栖虫类的多样性。该新属通过以下特征组合与其他介壳虫属区分开来：头长于前胸；眼不退化；触角短于身体；喙达甲喙；存在触角和股刚毛；中跖短于前胸；中跖后缘弯曲；中跖Ⅱ最长；有触角。

The second genus of pond treaders (Heteroptera: Mesoveliidae) from mid-Cretaceous amber of Myanmar

A new semi-aquatic bug genus of the family Mesoveliidae is described and illustrated from mid-Cretaceous Kachin amber, as Cretamesovelia pellai gen. et sp. nov. This new taxon represents the second mesoveliid genus documented from the deposits of Noije Bum Hill in northern Myanmar. Together with the recently described genus Myanmarvelia, this taxon provides further insights of the past diversity of semi-aquatic bugs. The new genus is distinguished from the other mesoveliid genera by the following combination of characters: head longer than pronotum; eyes not reduced; antennae shorter than body; rostrum reaching metacoxae; presence of antennal and femoral bristles; mesonotum shorter than pronotum; posterior margin of metanotum curved; metatarsi II longest; apterous.
