Taxonomic revision of the genus Aberdareleria (Diptera, Heleomyzidae, Oecotheini) with description of a new species from China

, in traits such as having reduced setae on the mid tibia (only anterodorsal and posterodorsal setae) and only spine-like setae on the female cercus (absence of hair-like setae). Through a taxonomic revision of the genus, we provide a diagnostic key, detailed morphological comparisons, and discuss the biogeographic implications of this transcontinental distribution, suggesting either ancient vicariance or avian-mediated dispersal. This discovery highlights the underestimated diversity of high-altitude Diptera in the Qinghai-Tibet Plateau.
