If there are any others, just toss them. I should have just swatted it and walked away:-)

to someone familiar with the fauna. Lack of pattern or spots on body and mostly pale hind basitarsus should limit the species possibilities

Most species with marked legs and unmarked thorax are in subgenera Simulium and Eusimulium. The latter, also known as the aureum species group, has gold scales somewhere near the back end of the thorax (postnotum)?

Subgenus may be possible without slide mounts. My reference book is inaccessible for the next few weeks. Look for distribution of hairs on R and/or R1, spines among fine hairs on costa, shape of modifications of end of basitarsus and second segment of tarsus of hind leg, and details of claws (with basal tooth, basal lobe, or simple, the first a common modification for grasping feathers).

Unfortunately some are pushing the limits of my scope. And I'm not sure of the current state of taxonomy vs MoND.

Claws appear to be simple, basal section of R bare, metatarsi appeared to have both calcipala and pedisulcus present. No gold scales visible on postnotum.

This is probably in the Simulium jenningsi species group, which has 0-4 hairs on the ventral side of the subcosta. If there is a more substantial row of hairs, it would be something like venustum or tuberosum.
