The detection of three sp. infective larvae in two specimens of the dung beetle (Marsham, 1802) from western Spain is reported here for the first time in Europe. Scanning electron microscopy confirmed that the analyzed specimens belong to the genus , but it was not possible to determine the species identity by the lack of morphological information in the literature and because many of the phenotypic characteristics had not yet fully developed at this juvenile stage. Nevertheless, a phylogenetic analysis using amplified nucleotide sequences has revealed that the studied larvae could be clearly discriminated (< 89% identity) from all the other sequences available in public genetic databases. While our results are limited by the scarcity of genetic information available for this genus, the possibility that the analyzed specimens might correspond to a new species should not be ruled out, and more studies are needed. The results provided in this report indicate that is involved in the transmission cycle of sp. to vertebrates in Europe.
本文首次报道了在西班牙西部两只粪金龟（Marsham，1802）标本中检测到三种感染性幼虫，这在欧洲尚属首次。扫描电子显微镜证实分析的标本属于该属，但由于文献中缺乏形态学信息，且许多表型特征在这个幼体阶段尚未完全发育，因此无法确定物种身份。尽管如此，使用扩增核苷酸序列进行的系统发育分析表明，所研究的幼虫可以与公共遗传数据库中所有其他可用序列明显区分开来（同一性<89%）。虽然我们的结果受到该属可用遗传信息稀缺的限制，但不能排除分析的标本可能对应一个新物种的可能性，还需要更多的研究。本报告提供的结果表明，该属参与了欧洲某种寄生虫向脊椎动物的传播循环。
