A new genus and species of fossil soldier beetle Markus karenae gen. et sp. nov. is described and illustrated from Eocene Baltic amber. Its morphological characteristics place it in the taxonomic position of the subfamily Silinae. It is characterized by a particular lateral pronotal shape with two difform processes, pronotum slightly longer than wide, with a blunt and evident angle near the basal angles, anterior and posterior margins flat and with shallow punctation, and lateral margin strongly granulose and in relief. Furthermore, each of its legs has a claw with one acute tooth at the base, except for the posterior legs where the tooth appears to be blunt. The new taxon is morphologically compared with the other fossil representatives of Silinae from Baltic amber, and with extant Palearctic genera.
描述并图示了一种来自始新世波罗的海琥珀的化石步甲新属新种——马库斯·卡雷纳步甲(Markus karenae gen. et sp. nov.)。其形态特征将它置于Silinae亚科的分类位置。它的特征在于前胸背板独特的侧面形状,有两个不同形状的突起,前胸背板略长于宽,在基部角附近有一个钝且明显的角,前缘和后缘平坦且有浅刻点,侧缘强烈颗粒状且凸起。此外,它的每条腿都有一个在基部有一个锐齿的爪,除了后腿的齿似乎是钝的。将这个新分类单元与来自波罗的海琥珀的Silinae亚科的其他化石代表以及现存的古北区属进行了形态学比较。
