For the first time, an extant histerid genus Horn, 1873 is described from a specimen found in mid-Cretaceous Kachin amber. sp. nov. Although the genus has not been precisely defined by synapomorphies, the new species shares numerous features with extant species while differing in comparatively few external characteristics. represents the first record of an extant histerid genus from Cretaceous deposits and provides further evidence of the ancient origin of the genus.
首次从缅甸克钦邦白垩纪中期琥珀中发现的标本描述了一个现存的阎甲属（Horn，1873）新物种。尽管该属尚未通过共衍征得到精确界定，但新物种与现存物种有许多共同特征，同时在相对较少的外部特征上存在差异。这是白垩纪沉积物中现存阎甲属的首次记录，并为该属的古老起源提供了进一步的证据。
