本文报道一新属一新种，秀丽华螺属Sinohelorus elegans gen.et sp.nov.被描述并分配到亚科Mesohelorinae，Heloridae。此外，还报道了两个新种：北票扁腹蛛Gurvanhelorus beipiao ensis sp. nov.和跳腹腹蛛Spherogaster saltatrix sp. nov.也被描述。根据新的材料和发现，对Gurvanhelorus Rasnitsyn，1986和Spherogaster Zhang和Zhang，2001的诊断进行了修正。这些标本采自辽宁省黄板鸡沟早白垩世义县组热河生物群。这些新种的发现拓宽了该科的多样性，并加深了我们对中侏罗世至今该科海象的后生结构、触角和前翅脉序演化趋势的认识。(c)2012爱思唯尔有限公司保留所有权利。
A new genus with a new species, Sinohelorus elegans gen. et sp. nov., is described and assigned to the subfamily Mesohelorinae, Heloridae. In addition, two new species, Gurvanhelorus beipiaoensis sp. nov. and Spherogaster saltatrix sp. nov., are also described. The diagnoses of Gurvanhelorus Rasnitsyn, 1986 and Spherogaster Zhang and Zhang, 2001 are emended based on new materials and findings. These well-preserved specimens were collected from the Jehol Biota, Early Cretaceous Yixian Formation of Huangbanjigou Village in Liaoning, China. These new species broaden the diversity of this family and enhance our understanding of evolutionary trend of helorid's metasomal structure, antenna, and fore-wing venation from the Middle Jurassic to extant.
