Hi all,

I'm looking to acquire molecular-grade specimens of Asilidae from all over the world, (and relevant to this post) especially south America. Such specimens would be instrumental in reconstructing the evolutionary history of these venomous predators, and also aid in their taxonomic revision and reclassification.

Would any of you included here have the means or interest to collect robber flies into 90-100% ethanol? Please let me know if so, and I can provide further details.

¿Alguno de ustedes incluido aquí tendría los medios o el interés de recolectar moscas ladronas en etanol al 90-100%? Si es así, avíseme y puedo proporcionar más detalles.

Algum de vocês incluído aqui teria os meios ou interesse para coletar moscas ladrão em etanol 90-100%? Informe-me se sim, e posso fornecer mais detalhes.

I hope you all are staying safe and healthy!

Best,
Chris

Species Groups on iNaturalist

About a month ago I made a feature request to add the "species group" taxon rank to the iNaturalist taxonomy: https://forum.inaturalist.org/t/create-a-new-taxon-rank-for-inaturalist-the-species-group/14543

This would aide in the identification of speciose genera (e.g. Efferia, Diogmites) where species complexes are not a valid substitute.

Unfortunately, this feature request has not received the attention I think it deserves. If you would like to see this powerful new tool added to our arsenal, please consider voting for this feature on the forum.

New Website: Robber Flies of the World

Today is World Robber Fly Day, and I can't think of a better time to announce the launch of my new website, Robber Flies of the World: https://www.robberfliesoftheworld.com.

As the name suggests, it covers all 7,200+ known species of these venomous predators, and focuses on their taxonomy, natural history and identification. My hope is that in the future it will become the go-to reference for just about anything pertaining to robber flies.

This has been a passion project of mine over the past 6 years or so. Because I decided to build it from the ground up, I've had to learn how to write and use HTML5, PHP, CSS, Javascript, and MySQL. While this means that I have had full control over the appearance and functionality of the site, it also means that there may be some uncaught bugs or glitches. I will continue to tweak and improve the site's appearance and performance over time, so let me know if you encounter any issues!

Robber Flies of the World currently has three main features:

  • Taxon Pages: Browse through every accepted subfamily, tribe, genus, and species. Over time each taxon page will be updated with diagnostic photographs and information pertaining to it's identification and natural history.
  • Species Catalog: Search by subfamily, tribe, genus, zoogeographic region, country and state to generate a catalog of species that match those criteria. Only accepted taxa are included, with junior synonyms listed for the relevant taxa.
  • Taxon Database: Search for a subfamily, tribe, genus, or species from a database of every known name used in Asilidae (over 12,00 records).

These are all generated from a MySQL database, which will allow me to quickly and easily modify classifications or add taxa as new taxonomic and phylogenetic studies are published.

The next big feature to be added to the website is the literature database, which will be incorporated into the taxon pages, species catalog, and taxon database as well as have a dedicated query page. Other major planned features include a predator-prey database, dichotomous keys, and matrix-based keys.

I hope you will find Robber Flies of the World to be a useful addition to your toolkit, and I look forward to your feedback!

If you want to get involved in the holiday festivities, consider posting your robber fly photos to Twitter with the hashtag #WorldRobberFlyDay ( https://twitter.com/search?q=%23WorldRobberFlyDay).

Species Complexes in Asilidae

I'm considering adding a few species complexes to the iNat taxonomy for Asilidae, particularly for North American Laphria and Efferia. Is this something that people would find useful? Does anyone have reservations about unranked taxa?

Which complexes would you like to see added?

iNat guidelines for complexes:
https://www.inaturalist.org/pages/curator+guide#complexes

Some discussions about species complexes for reference:
https://www.inaturalist.org/flags/346662
https://www.inaturalist.org/flags/331324
https://forum.inaturalist.org/t/how-are-species-complexes-treated/404

Three complexes added so far:
https://www.inaturalist.org/taxa/894751-Laphria-canis
https://www.inaturalist.org/taxa/894742-Laphria-sericea
https://www.inaturalist.org/taxa/894746-Laphria-index

To find a complex, search for the species name included in the respective link above, and the complex will be one of the two choices.

1b Mystax and legs entirely black………….nigerrimus
2a Black bristles and hairs on the lateral margins of the mesonotum; abdominal tergites 2-4 with grey pollen on the sides of the posterior margins; the last three tarsal joints black…..3
2b Yellow bristles and hairs on the lateral margins of the mesonotum; abdominal tergites 2-4 with
thick yellow pilosity on the sides of the posterior margins ; all tarsi yellow……rutilus
3a Anterior tibiae yellow with an elongated black spot on the ventral surface ; black bristles and hairs on the ocelar callus and occiput ( at least in schrottkyi)……….4
3b Anterior tibiae wholly yellow; yellow bristles and hairs on the ocelar callus and occiput….tucma
4a Antennae black; scutellum witli grey pollen on the dorsum………schrottkyi
4b Antennae and scutellum yellow…..jaliscoensis
