A new genus and species of Ptilodactylidae, Electrolichas circumbalticus gen. et sp. nov., the first fossil representative of the subfamily Anchytarsinae, is described from Baltic amber. This Eocene beetle can be distinguished from the extant genera of Anchytarsinae by the combination of the following characters: labrum transverse, terminal segment of maxillary palps cylindrical, antennae with non-articulated rami, basal pronotal margin only very finely crenulate, lacking a median denticle, anterior margin of scutellum not excised medially, elytra not striate, tarsi not pseudotetramerous, proportional lengths: 1.5: 1.2: 1.2: 1.1: 1.5, flashy pads on apex of first tarsomere as well as on tarsomeres 2-4. A list of the extant species of Anchytarsinae is provided. Both hitherto described fossil ptilodactylid genera are briefly discussed.
本文描述了来自波罗的海琥珀的拟毛跗甲科一个新属新种,环波罗的海电毛跗甲Electrolichas circumbalticus gen. et sp. nov.,它是锚跗甲亚科的首个化石代表。这种始新世甲虫可通过以下特征组合与锚跗甲亚科的现存属区分开来:上唇横向,下颚须末节圆柱形,触角具不分节的分支,前胸基部边缘仅具非常细微的细圆齿,无中齿,小盾片前缘在中部不凹陷,鞘翅无条纹,跗节非假四节状,比例长度为1.5: 1.2: 1.2: 1.1: 1.5,第一跗节顶端以及跗节2 - 4上有华丽的垫。提供了锚跗甲亚科现存物种列表。对迄今已描述的两个化石拟毛跗甲属进行了简要讨论。
