Provided here are web-based identification keys to Apioceridae, Asilidae, and Mydidae taxa, which have either been adapted from previously published keys and converted for web-based dissemination or the keys are more recent and developed specifically for web-based dissemination.
The software Lucid Phoenix is used to import paper-based keys or to create web-based dichotomous keys. Some of the previously published keys are illustrated with original drawings from the publication, added images, or links to respective web-sites with images. Multi-access, matrix-based identification keys are developed with Lucid Builder (version 3.5).

In order to use the keys, a reasonably fast internet connection is needed, Java has to be enabled in your browser, and a Java runtime version of 1.4.2 or greater is required.

Asilidae subfamily taxa sensu Dikow (2009)

Taxon coverage: Asilidae: : ( genera with species)
Geographical coverage: : world
Type of key:
multi-access, matrix-based (powered by Lucid Builder)
Notes:

- This interactive, matrix-based identification key is provided to place all Asilidae genera in the revised, phylogenetic classification of 14 subfamily taxa proposed by Dikow (2009), i.e., Asilinae, Bathypogoninae, Brachyrhopalinae, Dasypogoninae, Dioctriinae, Laphriinae, Leptogastrinae, Ommatiinae, Phellinae, Stenopogoninae, Stichopogoninae, Tillobromatinae, Trigonomiminae, and Willistonininae.

- The phylogenetic analysis, which is the basis for this classification, was published as Dikow (2009) and can be downloaded as an open-access PDF from the AMNH library.

- The characters for this key are taken from Table 7 and are illustrated with photographs and line drawings in the interactive key, which are partly taken from Dikow (2009). Photographs of Asilidae were kindly provided by Michael Thomas, Giff Beaton, Fritz Geller-Grimm, Riley Nelson, Eileen Collins, and Robert Copeland.

- keys to Baliomydas & Ceriomydas from Papavero and Wilcox 1971.
- Baliomydas tricolor not included as no specimens had been studied.
- Ceriomydas vespoides is not in the original key by Wilcox and Papavero 1971, but Ceriomydas darlingtoni is found twice so that T. Dikow resolved the key based on the included descriptions.
