记述了斑潜蝇科Jeholopsyche Ren，Shih et Labandeira三新种，全斑潜蝇Jeholopsyche completa sp. nov.，J.bella sp. nov.和J.maxima sp. nov.，的描述和说明。这些标本采自辽宁省黄板鸡沟热河生物群早白垩世义县组。新种的发现丰富了我们对该科的了解，扩大了该科的多样性，并为今后的系统发育研究提供了形态学特征。这些昆虫与虹吸长鼻支持先前记录的发现，neuretopsychids的分泌物和分泌物的同生裸子植物的生殖结构共存于义县组的流体饲养者。从喙的结构和推断的生态关系，我们认为，这三个新种，与喙的长度范围从3.5至14.5毫米，是传粉的裸子植物的主机，具有广泛的尺寸范围的深漏斗或其他管状结构，充满了花蜜样的流体奖励。(C)2012爱思唯尔有限公司保留所有权利。
Three new species of Jeholopsyche Ren, Shih et Labandeira in the family Aneuretopsychidae, Jeholopsyche completa sp. nov., J. bella sp. nov. and J. maxima sp. nov., are described and illustrated in this paper. These well-preserved specimens were collected from the Early Cretaceous of Yixian Formation, Jehol Biota, Huangbanjigou Village, Liaoning Province, China. The new species enhance our understanding and broaden the diversity of this family, and provide morphological characters for future phylogenetic studies of Aneuretopsychidae. These insects with siphonate proboscides support a previously documented finding that aneuretopsychids were fluid feeders on the secretions and exudates of contemporaneous gymnospermous reproductive structures coexisting in the Yixian Formation. From the proboscis structure and inferred ecological relationships, we believe that these three new species, with proboscid lengths ranging from 3.5 to 14.5 mm, were pollinators of gymnosperm hosts that bore a broad size-range of deep funnel or other tubular structures laden with nectar-like fluid rewards.
