A case of two spellings for Humboldt's blue-winged mosquito (Diptera: Culicidae).

While adding taxon names to the Systema Dipterorum database (Evenhuis Pape 2021), one of us (NLE) discovered that Humboldt (1819) had spelled the proposed name of a nominal mosquito species in two ways. He described the species, which was found in swampy places along the Magdalena River near Tenerife, Colombia, as Culex cyanopennis on page 340 and afterwards referred to it as Culex cyanopterus on pages 345 and 349. Both names have the same meaning: cyano- (Gr.

Nomenclatural Studies Toward a World List of Diptera Genus-Group Names Part VII: Johann Wilhelm Meigen.

The Diptera genus-group names of Johann Wilhelm Meigen are reviewed, revised, and annotated. A total of 266 available genus-group names in 69 families of Diptera are listed alphabetically, including authorship, year and page of the original publication, originally included species, type species and method of fixation, current status of the name, family placement, and any emendations that have been found in the literature. Unavailable names suppressed by ICZN rulings as well as incorrect original and subsequent spellings are included as unnumbered entries.

Nomenclatural studies toward a World List of Diptera genus-group names. Part VI: Daniel William Coquillett.

The Diptera genus-group names of Daniel William Coquillett are reviewed and annotated. A total of 136 available genus-group names in 53 families of Diptera are listed alphabetically, and for each name giving author, year and page of original publication, originally included species, type species and method of fixation, current status of the name, family placement, and a list of any emendations of it that have been found in the literature. Remarks are given to clarify nomenclatural or taxonomic information.

Battling the un-dead: the status of the Diptera genus-group names originally proposed in Johann Wilhelm Meigen's 1800 pamphlet.

The work of Meigen 1800 was suppressed by the ICZN Commission in 1963 for the purposes of zoological nomenclature. The work as such is still to be treated as having been published and it remains available as a source of published descriptions and illustrations. Therefore, while the names in Meigen (1800) are deemed unavailable, a subsequent usage of any of the names may be considered a novel proposal.

Review of the Oriental and Palaearctic bee fly genus Bigot (Diptera: Bombyliidae: Bombyliinae).

The bee fly genus Euchariomyia Bigot is reviewed and new records from the Oriental Region are given. Five names (for four species-level taxa) have been associated with species in the genus. Examinations of types, as well as homotypic and topotypic specimens, shows all five names to belong to a highly variable single species, Euchariomyia dives Bigot.

New species without dead bodies: a case for photo-based descriptions, illustrated by a striking new species of Marleyimyia Hesse (Diptera, Bombyliidae) from South Africa.

A new bombyliid species Marleyimyia xylocopae Marshall & Evenhuis, sp. n., an apparent mimic of the carpenter bee Xylocopa flavicollis (De Geer), is described from South Africa on the basis of photographs only.

Nomenclatural Studies Toward a World List of Diptera Genus-Group Names. Part IV: Charles Henry Tyler Townsend.

The Diptera genus-group names of Charles Henry Tyler Townsend are reviewed and annotated. A total of 1506 available genus-group names in 12 families of Diptera are listed alphabetically for each name, giving author, year and page of original publication, originally included species, type species and method of fixation, current status of the name, family placement, and a list of any emendations of it that have been found in the literature. Remarks are given to clarify nomenclatural and/or taxonomic information.

Clarification of the authorship, type species, and date of the genus Taxigramma (Diptera: Sarcophagidae).

The authorship and date of publication of the genus Taxigramma is found to be established by Macquart in 1850, with the type species Miltogramma heteroneura Meigen, 1830, by monotypy. A history of the name and its junior synonym Heteropterina Macquart, 1854, is given. 

The Campsicnemus popeye species group (Diptera: Dolichopodidae) from French Polynesia.

A new species-group (the popeye group) of the mega-diverse dolichopodid genus Campsicnemus from French Polynesia is described to include six new species: C. craigi Evenhuis, sp. nov.

Nomenclatural studies toward a world catalog of Diptera genus-group names. III. Christian Rudolph Wilhelm Wiedemann.

The Diptera genus-group names of Christian Rudolph Wilhelm Wiedemann are reviewed and annotated. A total of 50 available genus-group names in 25 families of Diptera are listed alphabetically for each name giving author, year and page of original publication, originally included species, type species and method of fixation, current status of the name, family placement, and a list of any emendations of it that have been found in the literature. Remarks are given to clarify nomenclatural or taxonomic information.
