Abstract

Since the first description from China, the Mesozoic dictyopteran family Umenocoleidae was recorded from the Eurasian and South American continents with 18 genera and 31 species. Here, we describe one new genus and three species from the Jinju Formation, South Korea: Umenocoleus minimus sp. nov., Pseudoblattapterix weoni gen. et sp. nov., and Petropterix koreaensis sp. nov. We also discuss three new apomorphies of the Umenocoleidae and Alienopteridae, which are 1) M, Cu and PCu1 veins form an common vein near wing base, 2) M, Cu and PCu1 veins appress to R vein and 3) CuP + PCu1 vein are not as concave as in the other Holopandictyoptera (total group of extant Blattodea and Mantodea). On the basis of these new apomorphies, we support the inclusion of the family Alienopteridae into the superfamily Umenocoleoidea. We also support the exclusions of the genera Vitisma and Permoponopterix from the Umenocoleidae family and propose to transfer the genus Permoponopterix into the Protelytroptera.

来自韩国的新阿尔卑斯属、新阿尔卑斯种和另外两个新Umenocoleidae (Dictyoptera) 种

自中国首次描述以来，欧亚大陆和南美大陆共记录到中生代双翅目卯卯虫科 18 属 31 种。在这里，我们描述了来自韩国晋州地层的一个新属和三个新种：Umenocoleus minimus sp.我们还讨论了 Umenocoleidae 和 Alienopteridae 的三个新的非形态特征，即 1）M、Cu 和 PCu1 脉在翅基附近形成一个共同的脉；2）M、Cu 和 PCu1 脉与 R 脉贴伏；3）CuP + PCu1 脉不像其他 Holopandictyoptera（现生蜚蠊科和螳螂科的总类）那样凹陷。根据这些新的非形态特征，我们支持将 Alienopteridae 科归入 Umenocoleoidea 超科。我们还支持将 Vitisma 属和 Permoponopterix 属从 Umenocoleidae 科中剔除，并建议将 Permoponopterix 属转入 Protelytroptera 科。

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.
