Abstract

A new fossil bee species, Liotrigona (Tapheiotrigona) aethiopica Engel, new subgenus and species, was described and figured from a worker preserved in Miocene amber from Ethiopia. The species represents the first fossil bee from Africa, predating the many subfossil occurrences otherwise known from Holocene copal and Defaunation resins. The new species is distinguished from its congeners and placed in a new subgenus based on differences in malar space length, wing venation, keirotrichia of the metatibia, and structure of the mesoscutellum and propodeum.
非洲首个蜜蜂化石:埃塞俄比亚中新世琥珀中无刺蜂属Liotrigona(膜翅目:蜂科)
一个新的蜜蜂化石物种,Liotrigona(Tapheiotrigona)aethiopica Engel,新的亚属和物种,是从埃塞俄比亚中新世琥珀中保存的一名工人身上描述和描绘的。该物种代表了第一个来自非洲的蜜蜂化石,早于全新世copal和Defaunation树脂中的许多亚化石。该新物种与其同源物种不同,并根据马耳间隔长度、翼脉、后胫骨的keirotrichia以及中小细胞和前小细胞结构的差异,将其归入一个新的亚属。
