A new genus of Cephenniini, Papuamicrus gen. n. (type species Papuamicrus globosus sp. n.) is described based on specimens collected in Papua New Guinea. The new genus belongs to the Cephennomicrus group of genera and is characterized by a highly reductive morphology of the dorsum, lacking pronotal pits and elytral foveae, but having uniquely shaped prosternal and mesoventral processes and a highly unusual for Cephenniini aedeagal structure with a basal lentiform sclerotization situated at middle of a small diaphragm shifted to the basal surface of the median lobe. Updated identification key to the world genera of Cephenniini is given to accommodate the new taxon.
本文基于在巴布亚新几内亚采集的标本,描述了一个新的 Cephenniini 属,即 Papuamicrus 属(模式种为 Papuamicrus globosus sp. n.)。该新属属于 Cephennomicrus 属群,其特征为背部高度退化,缺乏前胸窝和鞘翅窝,但具有独特形状的胸板和中胸突,以及对 Cephenniini 来说非常不寻常的阳具结构,其基部呈泪滴形的硬化位于小隔膜的中部,移至中隔叶的基部表面。为了容纳这个新分类单元,给出了世界 Cephenniini 属的修订识别关键。
