ABSTRACT We revise the genus Mesotipula Handlirsch, 1920 (Diptera, Limoniidae) described from the Lower Toarcian (Lower Jurassic) of Northeast Germany. Mesotipula was originally separated from other Architipulinae on the base of a bifurcated vein M3, which appeared artificial after the restudy of its holotype. Holotypes of all Limoniidae described by Handlirsch and Krzeminski and Zessin from the Lower Toarcian deposits of Northeast Germany (Dobbertin and Grimmen) are revised to provide an updated diagnosis of Mesotipula and to distinguish it from other genera. As a result, the following species described by Handlirsch within the genus Architipula are transferred to the genus Mesotipula: A. geinitzi Handlirsch syn. nov., A. minuta Handlirsch comb. nov. and A. parva Handlirsch syn. nov. In addition Eotipula lapidaria Handlirsch is also transferred to Mesotipula. Now we regard six species of Mesotipula as being valid in the Lower Toarcian of Northeast Germany.

来自德国东北部下侏罗统的 Mesotipula Handlirsch 属的修订版，1920 年（双翅目、Limoniidae、Architipulinae）

摘要 我们修订了从德国东北部下托亚纪（下侏罗纪）描述的 Mesotipula Handlirsch 属，1920（双翅目，Limoniidae）。Mesotipula 最初在分叉静脉 M3 的基部与其他 Architipulinae 分离，在其正模模型重新研究后出现人工。Handlirsch、Krzeminski 和 Zessin 描述的所有 Limoniidae 的正模来自德国东北部的下 Toarcian 矿床（Dobbertin 和 Grimmen）都经过修订，以提供 Mesotipula 的最新诊断并将其与其他属区分开来。因此，Handlirsch 在 Architipula 属内描述的以下物种被转移到 Mesotipula 属：A. geinitzi Handlirsch syn。11 月，A. minuta Handlirsch 梳子。十一月 和 A. parva Handlirsch Syn。十一月 此外，Eotipula lapidaria Handlirsch 也转移到 Mesotipula。现在我们认为 Mesotipula 有 6 种在德国东北部的下托尔克西亚有效。
