On Loew,

I'm cutting a few corners here but in short.....Loew introduced "groups" based on exteral characters of males in particular (total machimus group probaby based on shape of female ovipositor).

Machimus > males have a protrusion on the hind margin of the eighth sternite. Like the kite tail of M. atricapillus.

Epitriptus > No protrusion, lighter coloured creatures with light colored tibia with little black markings and femora with red stripes. Legs with tiny hairs that give them a dull look.

Tolmerus > No protrusion, darker coloured animals with more or less shiny and darker legs with less red markings .

Since then a lot has changed, maybe this will be continued. I will start in Lehr now who eliminated Epitriptus and introduced Neoepitriptus ao things. Asilus atricapillus > Machimus atricapillus > Tolmerus atricapillus. and so on.
