Based on a well-preserved specimen from Upper Eocene Baltic amber (Kaliningrad region, Russia), Microbregma waldwico sp. nov., the second fossil species of this genus, is described. The new species is similar to the extant Holarctic M. emarginatum (Duftschmid), 1825, and fossil M. sucinoemarginatum (Kuśka), 1992, but differs in its shorter abdominal ventrite 1 (about 0.43 length of ventrite 2) and larger body (5.1 mm). A key to species of the genus Microbregma is given, and a check-list of described fossil Ptinidae is provided. The fossil record of Ptinidae now includes 48 species in 27 genera and 8 subfamilies.
基于一块保存完好的始新世晚期波罗的海琥珀标本（俄罗斯加里宁格勒地区），描述了该属的第二个化石物种——新种瓦氏微短鞘叩甲（Microbregma waldwico sp. nov.）。新物种与现存的全北区的微短鞘叩甲（Microbregma emarginatum (Duftschmid)，1825）以及化石种琥珀微短鞘叩甲（Microbregma sucinoemarginatum (Kuśka)，1992）相似，但腹部第一腹板较短（约为第二腹板长度的0.43倍）且体型较大（5.1毫米）。给出了微短鞘叩甲属物种检索表，并提供了已描述化石窃蠹科的清单。窃蠹科的化石记录现在包括27个属和8个亚科中的48个物种。
