Microweiseinae is a quite recently established subfamily within ladybird beetles (Coccinellidae). According to recent analyses of morphological and molecular data, it has been divided into three tribes. Members of the subfamily are distributed mostly in tropical and subtropical regions of the world. Despite several recent taxonomical studies of this group, its diversity and distribution is still not fully understood. Recent field collecting on Madeira Island resulted in the discovery of interesting specimens belonging to a yet unknown taxon, described here as Madeirodula atlantica gen. et sp. nov. Phylogenetic analysis of morphological characters indicate that the new taxon form a distinct branch within the subfamily Microweiseinae, for which we propose a new tribe Madeirodulini trib. nov. Evolutionary trends within the subfamily are discussed, and an updated key to the tribes of Microweiseinae is provided.

在北大西洋的一个岛上发现的瓢虫甲虫亚科的一个新部落（鞘翅目：瓢虫科）。

Microweiseinae是瓢虫（Coccinellidae）的一个新近建立的亚科。根据最近对形态学和分子数据的分析，它分为三个部落。该亚科的成员主要分布在世界的热带和亚热带地区。尽管最近对该组进行了一些分类学研究，但其多样性和分布仍未完全了解。马德拉岛（Madeira Island）上最近的野外采集导致发现了一个有趣的标本，该标本属于一个未知的分类群，在这里被称为马德罗德拉（Madeirodula atlantica） gen。等。十一月 形态学特征的系统发育分析表明，新的分类群在亚科Microweiseinae中形成了一个独特的分支，为此我们提出了一个新部落马德罗杜里尼部落 十一月 讨论了亚科内的进化趋势，并提供了微藻科的更新密钥。
