Abstract

A new genus with two new species of Micropterigidae, Terncladus lunatus Han, Zhang et Ren gen. et sp. nov. and Terncladus halonatus Han, Zhang et Ren sp. nov., are erected based on three well-preserved specimens in Late Cretaceous Kachin amber. The new genus can be identified by hind wing with veins Sc unforked, no trace of free R, and Rs three-branched. Furthermore, we applied Geometric Morphometric Analyses (GMA) to study 26 species with well-preserved forewings of Micropterigidae and presented the results for the first time. The GMA results confirmed the classification of the new genus and shed light on the differences and diagnoses of the five monophyletic lineages of Micropterigidae. By comparing the geographical distribution and climatic environment characteristics of Micropterigidae in different geological periods, Micropterigidae have a relatively conservative adaptability to the environment during the evolutionary process.

鳞翅目小蝶科（Micropterigidae）世系的几何形态分析以及缅甸北部中白垩世琥珀中的两个新种

根据在晚白垩世克钦琥珀中发现的三个保存完好的标本，建立了一个新属和两个新种，即Terncladus lunatus Han, Zhang et Ren gen.新属的特征是后翅脉Sc未分叉，无游离R的痕迹，Rs三分枝。此外，我们还应用几何形态计量分析法（GMA）研究了 26 个前翅保存完好的蝶形目物种，并首次公布了研究结果。几何形态分析结果证实了新属的分类，并揭示了小蝶科五个单系的差异和诊断。通过比较小戟科在不同地质时期的地理分布和气候环境特征，发现小戟科在进化过程中对环境的适应性相对保守。

期刊介绍： Cretaceous Research provides a forum for the rapid publication of research on all aspects of the Cretaceous Period, including its boundaries with the Jurassic and Palaeogene. Authoritative papers reporting detailed investigations of Cretaceous stratigraphy and palaeontology, studies of regional geology, and reviews of recently published books are complemented by short communications of significant new findings. Papers submitted to Cretaceous Research should place the research in a broad context, with emphasis placed towards our better understanding of the Cretaceous, that are therefore of interest to the diverse, international readership of the journal. Full length papers that focus solely on a local theme or area will not be accepted for publication; authors of short communications are encouraged to discuss how their findings are of relevance to the Cretaceous on a broad scale. Research Areas include: • Regional geology • Stratigraphy and palaeontology • Palaeobiology • Palaeobiogeography • Palaeoceanography • Palaeoclimatology • Evolutionary Palaeoecology • Geochronology • Global events.
