Apystomyia elinguis is a North American relict species of fly. It has been identified through phylogenomic analysis as the sister group to the Cyclorrhapha, a placement supported by a comprehensive molecular matrix of nuclear genes, mitochondrial genomes, and morphological characters.[1] Its evolutionary position is significant for understanding the relationships within the Brachycera and the subsequent rapid radiation of the Schizophora.[1]
This page represents the following TreeOfLife-200M taxonomic path.[2]
Based on observations from the TreeOfLife-200M dataset, Apystomyia elinguis exhibits a small, fly-like body form typical of many Brachycera.[2] The specimens display a distinct, rounded head structure and a thorax with visible setal patterns.[2] The wings are clear and membranous, with a venation pattern characteristic of its taxonomic placement.[2]
