The subgenus Eutricharaea Thomson of the genus Megachile Latreille (Hymenoptera: Megachilidae) in Egypt is revised. Fifteen species are recognized, of which two are new: Megachile laniventris Praz sp. nov. and M. rufomandibularis Praz sp. nov. In addition, three unclear taxa known from few specimens in one sex are documented to facilitate future work. The following new synonymies are proposed: M. microxantha Cockerell 1937, M. privigna Rebmann 1968, and M. submucida Alfken 1926 are synonymized with M. leucostoma Prez 1907 (syn. nov.); M. blanda Rebmann 1968 with M. walkeri Dalla Torre 1896 (syn. nov.); M. uniformis Alfken 1934 (not M. uniformis Mitchell 1929) and the replacement name M. minutuloides Alfken 1936 with M. minutissima Radoszkowski 1876 (syn. nov.); and M. tkalcui Zanden 1996 with M. rugipuncta Alfken 1934 (syn. nov.). Lectotypes are designated for M. soikai Benoist 1961, M. rugipuncta, M. tenuistriga Alfken 1938, M. niveascopa Ferton 1908, and M. naevia Kohl 1906. The previously unknown males of M. impressipuncta Alfken 1934 and M. rugipuncta, as well as the undescribed female of M. soikai are described. Illustrated keys for both males and females are provided and DNA barcodes are published for most species.
埃及 Megachilidae 科 Megachile Latreille 属的 Eutricharaea Thomson 亚属进行了修订。共鉴定出 15 个种，其中 2 个为新种：Megachile laniventris Praz sp. nov. 和 M. rufomandibularis Praz sp. nov. 此外，还记录了三个因标本数量较少而不清楚的分类单元，以便为未来的工作提供便利。提出了以下新的同物异名：M. microxantha Cockerell 1937、M. privigna Rebmann 1968 和 M. submucida Alfken 1926 与 M. leucostoma Prez 1907 同义（新同物异名）；M. blanda Rebmann 1968 与 M. walkeri Dalla Torre 1896 同义（新同物异名）；M. uniformis Alfken 1934（非 M. uniformis Mitchell 1929）和替代名 M. minutuloides Alfken 1936 与 M. minutissima Radoszkowski 1876 同义（新同物异名）；以及 M. tkalcui Zanden 1996 与 M. rugipuncta Alfken 1934 同义（新同物异名）。为 M. soikai Benoist 1961、M. rugipuncta、M. tenuistriga Alfken 1938、M. niveascopa Ferton 1908 和 M. naevia Kohl 1906 指定了模式标本。描述了以前未知的 M. impressipuncta Alfken 1934 和 M. rugipuncta 的雄性以及未描述的 M. soikai 的雌性。提供了雌雄两性的鉴别特征，并公布了大多数物种的 DNA 条形码。
