Glutops
Burgess, 1878
Glutops is a of flies in the Pelecorhynchidae, established by Burgess in 1878. The genus comprises eleven described distributed across the Holarctic region. These flies are part of a small family of predatory or parasitic dipterans closely related to snipe flies (Rhagionidae). The genus has received limited study, with most species described in the mid-20th century based on morphological characters.

Identification
Members of Glutops can be distinguished from related in Pelecorhynchidae by combinations of wing venation patterns, antennal structure, and genital . -level identification requires examination of male terminalia and specific wing markings. The genus is characterized by a compact body form and reduced mouthparts compared to some related rhagionoid flies. Detailed diagnostic features vary by species and require taxonomic keys.
Distribution
of Glutops have been recorded from North America (including the United States and Canada), Japan, and Russia. The shows a disjunct Holarctic distribution pattern, with species occurring in temperate and regions of both the Nearctic and Palearctic realms.
Similar Taxa
- PelecorhynchusBoth belong to Pelecorhynchidae and share general body plan and wing venation, but Pelecorhynchus are generally larger with more robust mouthparts adapted for blood-feeding on vertebrates.
- RhagioRhagio (Rhagionidae) resembles Glutops in general appearance as a rhagionoid fly, but differs in -level characters including larval and mouthpart structure; Glutops has been historically classified within Rhagionidae by some authorities.

Taxonomic instability
The placement of Glutops has been debated; GBIF currently lists it under Rhagionidae, while most modern sources (NCBI, Catalogue of Life, recent literature) recognize Pelecorhynchidae as a distinct family. This reflects ongoing uncertainty about higher-level relationships among rhagionoid flies.
Species diversity
The eleven described span nearly a century of taxonomic work (1878–1971), with several species described by Teskey in 1970 based on North American material. The remains poorly collected, with only 8 observations recorded on iNaturalist as of source date.
