Thirty-nine species of sawfly (Symphyta) are recorded for the first time in Bulgaria. Most of these were collected during early spring of 2018, in the south-east of the country (Burgas and Varna Provinces). Empria aridicola Macek & Prous, sp. nov. is described as new to science from specimens collected in several central, east and south European countries. Lectotypes are designated for Poecilosoma parvula Konow, 1892, Empria pravei Dovnar-Zapolskij, 1925 and E. pseudoklugi Dovnar-Zapolskij, 1929. Empria pravei and Sciapteryx byzantina Benson, 1968 are at present only known in Europe from the coastal zone of the Black Sea. The new Bulgarian records of Hoplocampa cantoti Chevin, 1986 and Neomessa steusloffi (Konow, 1892) represent large extensions in their recorded ranges, previously comprising respectively only northern France, and north-eastern Germany. Possible host plant associations are noted for several species, based on observations of adults.

在保加利亚锯齿上，包括一种新的Empria（膜翅目，Symphyta）

在保加利亚首次记录了39种锯蝇（Symphyta）。其中大多数是在该国东南部（布尔加斯和瓦尔纳省）于2018年初春收集的。Empria aridicola Macek＆Prous，sp。十一月 在几个中欧，东欧和南欧国家/地区收集的标本中，这种元素被描述为科学的新手。Lectotypes被指定为小孢子虫（Poecilosoma parvula Konow，1892年），Empria pravei Dovnar-Zapolskij（1925年）和E. pseudoklugi Dovnar-Zapolskij（1929年）。Empriapravei和Sciapteryx byzantina Benson，1968年在欧洲仅在黑海沿岸地区有名。保加利亚的Hoplocampa cantoti Chevin（1986年）和Neomessa steusloffi（Konow，1892年）的新记录代表了记录范围的大扩展，以前分别仅包括法国北部，和德国东北部。根据成年动物的观察，注意到了几种物种可能的寄主植物关联。
