Nitidulidae is the most diverse family of the recently recognized superfamily Nitiduliodea, but Mesozoic nitidulids that are critical for understanding their early diversification are sparse. Here, we report a new genus and species of Nitidulidae, gen. et sp. nov., that was recovered from mid-Cretaceous amber in northern Myanmar. The new genus is distinguished from all members of the extant nitidulid subfamilies most prominently by the loose antennal club and the absence of subantennal grooves. can be excluded from the closely related Kateretidae and classified into Nitidulidae by the broad and apically expanded prosternal process, although it has many pleisiomorphic characters.
露尾甲科是最近被认可的露尾甲总科中最多样化的一个科，但对于理解其早期多样化至关重要的中生代露尾甲却很稀少。在此，我们报告了一个从缅甸北部白垩纪中期琥珀中发现的露尾甲科新属新种。这个新属与现存露尾甲亚科的所有成员最显著的区别在于触角棒松散且没有亚触角沟。尽管它有许多祖征性状，但通过宽阔且顶端扩展的前胸腹板突，可以将其与亲缘关系密切的扁甲科区分开来，并归入露尾甲科。
