我国上侏罗统牛津阶—基末利阶 (163— 15 0 Ma)保存有完好的最原始的蠼螋昆虫化石。首次描述、分析和讨论了原始蠼螋后翅脉序特征 ,认为与现代生存的蠼螋后翅基本相同。因此 ,提出了与西方某些蠼螋昆虫分类学者不同的意见 ,认为始螋亚目 (Aechidermaptera)应归入于革翅目 (Dermaptera)之中 ,且视其为一个最原始的类群较为合理。内蒙古自治区这个原始类群的下列重要特征皆为首次发现 :胸骨具有特殊的形态结构 ;革翅锁具 (Tegminalocking device)和刺脊突 (spiny crest)发育 ;前、中、后足跗节皆为 5节 ;后足基节显著伸长 ;颈部被划分为前、后两个颈片 ;革翅后缘收缩变尖。上述 5项被视为最原始蠼螋特有的祖征。下列特征应为早期蠼螋共有的原始性状 :虫体扁平 ,通常具毛 ;腹部侧缘彼此近平行 ;触角显长 ,丝状 ,多节 (通常多于 11节 ) ;两只单眼发育 ;上颚具齿 ;中胸小盾片显大 ;革翅较长 ,通常具有明显的翅脉 ;股节具隆脊 ;爪和爪垫通常发育 ;腹部各节背板与腹板不重叠 (两者位置非简单的上、下关系 ) ;尾须柔软、多节 ;雌性产卵器鞘显著外伸。本文建立了始螋亚目 1新科 Sinopalaeo-dermatidae和 2新属 2新种 Sinopalaeodermata neimonggolensisgen.etsp.nov.,Jurassimedeola orientalis gen.etsp.nov.。
The Upper Jurassic Oxfordian-Jidieli Strait (163-1500 Ma) in China has preserved intact primitive fossil fossils. It is the first time to describe, analyze and discuss the characteristics of the hindwing veins of the primitive clam, which is considered to be basically the same as the hind wing of the modern clan. Therefore, different opinions have been proposed from some western taxonomic taxonomists, suggesting that Aechidermaptera should be classified as Dermaptera, and it is more reasonable to regard it as one of the most primitive taxa. The following key features of this primitive group in Inner Mongolia are the first to be found: the sternum has a special morphological structure; Tegminalocking device and spiny crest develop; ; Base of the hind foot is significantly elongated; the neck is divided into before and after the two neck pieces; leather wing trailing edge contracted sharp. The above five items are considered the most primitive emperor 螋 螋 unique ancestry. The following traits should be common to the early stage common grubs: the worms are flat and usually hairy; the lateral margins of the abdomen are nearly parallel to each other; the antennae are elongated, filiform, multisearth (usually more than 11); two monocularly developed; With small teeth; mid-chest scutellum was large; leather wings longer, usually with distinct veins; spine with spine; claw and paw pads usually develop; abdomen sections of the back plate and web do not overlap (both non-position Simple upper and lower relationship); tail to be soft, multi-section; female oviposit sheath significantly overhanging. In this paper, Sinopalaeo-dermatidae and 2 new genus 2 Sinopalaeodermata neimonggolensisgen.etsp.nov., Jurassimedeola orientalis gen.etsp.nov were established.
