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.

Key to Dicranus

Adapted from Carrera, 1955. Carrera did not have access to specimens of D. jaliscoensis, so this key will need to be modified/updated.

1a Mystax yellow; legs entirely yellow or with black spots……2
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
