Looking at this more closely, I don't think this is
fuscata. Photo 4 clearly shows the scutellum has a reddish-yellow apex, which fuscata should not have. I'm pretty sure it's either
tuguriorum or
scutellata.
Fonseca separates these females as follows:
tuguriorum - frons at vertex more than two-fifths head width; jowl below eye about half eye-height; palpi reddish-yellow on basal third.
scutellata - frons at vertex only one-third head width; jowl below eye not more than one-third eye-height; palpi usually almost entirely black.
If I was pushed on this, I'd say
scutellata, but I think the frons is too wide, so we need a big "?" after the name. ;)
