We report on new findings of nearly 50 species that represent four families of the superfamily Scarabaeoidea, which were collected during an expedition to western Tajikistan that was carried out in June and July 2014. Rhyssemodes transcaspicus Rakovič, 1982 is recorded from the country for the first time. Moreover, we describe and illustrate the differences in the external morphology between Euonthophagus gibbosus (Scriba, 1790) and E. koshantschikoffi (Reitter, 1891), the latter of which has a doubtful systematic position. In the collected material of approximately 1,000 specimens, more than 90% of the species and 95% of the individuals belong to the family Scarabaeidae. The other species represent the families Geotrupidae, Glaphyridae, and Hybosoridae.

塔吉克斯坦的金龟子甲虫（鞘翅目，Scarabaeoidea）的新发现和有趣的发现

我们报告了近50种物种的新发现，这些物种代表超甲壳虫科的四个科，这些科目是在2014年6月和7月对塔吉克斯坦西部的一次考察中收集的。Rhyssemodes transcaspicusRakovič，1982年是该国的第一次记录。时间。此外，我们描述和说明了Euonthophagus gibbosus（Scriba，1790）和E. koshantschikoffi（Reitter，1891）之间在外部形态上的差异，后者的系统地位令人怀疑。在大约1,000个标本的收集材料中，超过90％的物种和95％的个体属于金龟子科。其他物种代表Geo藜科，剑兰科和s科。
