Discussion.--Bolivian Eldredgeia venustus (Wolfart, 1968)
typically has 26-27 dorsoventral files on each eye with a maximum
of eight to nine lenses/file. Cooper (1982) reported that
South African Eldredgeia cf. venustus has only 18 dorsoventral
files with a maximum of six to seven lenses/file (although the
two species have similar Large-Eye Indices). In addition, South
African E. cf. venustus has L3 more inflated and L2 and LI
relatively shorter than Bolivian E. venustus. Therefore, at least
two species can be assigned to this genus, the Bolivian E. venustus
and the South African E. cf. venustus.

Thus, there may be four slightly differentiated forms
of Eldredgeia known from different geographic regions.

I'm hoping Piranha will indulge me a bit.

 My gray hair and beard say otherwise.   

These are quite nice, Tim. Kudos on this snag o' swag. Give us a sense of scale here. Are they wee, or big, fellas?

The prone one on the lower left is maybe 2 inches long. I'll add some measurements a bit later. 

Is that the one you are giving me?  

Those are fairly large ones! The furrows in the glabella remind me of Flexis and Greenops.

The info I got with my example (Eldredgeia venustus) is:

Belen Fm (upper mbr.) - Eifelian

Calamarca (La Paz), Bolivia

That's on the northern Altiplano, apparently.

There is/are related formation(s) that also produce trilos, ie. the Sica Sica Fm (Givetian), though I'm not sure if the same trilos occur in both. (My Sica Sica trilo is Cryphaeoides rostratus)

This info is from the seller, and I'll take his word for it.
