摘要

摘要埃塞俄比亚中新世早期琥珀中描述了一种新的、已灭绝的异狄亚温纳茨琥珀。古非洲异足虫（Allodia paleoafricana sp.nov.）的主要特征是盾壳具有强大的前边缘、背中心体和侧刚毛，翼部M叉的茎略短于脉r–M，M4–CuA叉的基部与r–M的基部对齐。由于化石混合了这两个分类群中发现的特征，因此对严格意义上的异狄亚属或温纳茨短臂虫这两个亚属中任何一个的归属仍然模糊不清。异足虫主要分布在北极地区，而在非洲只有少数物种被描述。在这方面，来自埃塞俄比亚的新化石物种为该属的温带分布和自然历史带来了重要的新信息。

The genus Allodia (Diptera: Mycetophilidae) in Miocene Ethiopian amber

Abstract. A new, extinct species of Allodia Winnertz is described from early Miocene amber of Ethiopia. Allodia paleoafricana sp. nov. is mostly characterized by the scutum with strong anteromarginal, dorsocentral, and lateral setae and the wing with the stem of the M-fork slightly shorter than the vein r–m and the base of the M4–CuA fork aligned with the base of r–m. The assignment to any of the two subgenera Allodia stricto sensu or Brachycampta Winnertz remains equivocal as the fossil intermingles traits found in both taxa. Allodia is known mostly from the Palearctic region, while only a few species have been described from Africa. In this regard, the new fossil species from Ethiopia brings significant new information regarding the Afrotropical distribution and natural history of the genus.

期刊介绍： Fossil Record (FR) is the palaeontological journal of the Museum für Naturkunde Berlin. This journal was founded in 1998 under the name Mitteilungen aus dem Museum für Naturkunde Berlin, Geowissenschaftliche Reihe and appears with two issues each year. Fossil Record publishes original papers in all areas of palaeontology including the taxonomy and systematics of fossil organisms, biostratigraphy, palaeoecology, and evolution. All taxonomic groups are treated, including invertebrates, microfossils, plants, and vertebrates.
