= Omophoita magniguttis Bechyné, 1955
a look-alike species, widespread in Brazil. Several web images of "albicollis" are in fact this. True albicollis:

colour more brown, spots smaller
Note the oblique and elongated "pin-like" white patch for Albicollis. Eulalia's has a round patch. Personally I would still go with Omophoita sp.

Thanks anyway for your re-search efforts!
Suppose you know that the color on the picture is not same but more brown because of the combination of alcohol/acetone during the preparation, but the insect is the same :)
