摘要：
The Eumerus triangularis group (Diptera: Syrphidae: Merodontini), which is endemic to the Afrotropical Region, has been thoroughly reviewed. This study identifies nine species within the group, with four of them redescribed: E. rubidus Hull, 1964, E. tessellatus Hull, 1964, E. triangularis Herv & eacute;-Bazin, 1913, and E. villeneuvei Herv & eacute;-Bazin, 1913 and with the description of four new species - E. argentipedicellus Radenkovi & cacute;, Vuji & cacute; & Grkovi & cacute; sp. nov., E. brunnipennis Radenkovi & cacute;, Vuji & cacute; & Grkovi & cacute; sp. nov., E. clavicercus Radenkovi & cacute;, Vuji & cacute; & Grkovi & cacute; sp. nov., and E. setifemoratus Radenkovi & cacute;, Vuji & cacute; & Grkovi & cacute; sp. nov. Furthermore, the previously unknown male of E. rubidus and the female of E. tessellatus are described. This study includes illustrated identification keys for males and females, along with detailed drawings of male terminalia for all nine species. DNA sequences of two regions of the mitochondrial DNA, cytochrome c oxidase subunit 1 (COI) gene and cytochrome b, and a region of the nuclear ribosomal 28rRNA gene are used to confirm morphological identification. Both molecular and morphological analyses indicate the presence of two distinct clades within the E. triangularis species group.
