Comparison of the Resolution Achieved in Glycerol and Malinol

Photos taken in glycerol are shown on the left, those taken in Malinol on the right.

The first example shows the ventral view of the terminalia of a Trichocera saltator, aedeagal complex and ninth tergite removed. The main difference is, that the hairs, especially on the gonocoxites, appear too thick, which is simply due to the worse resolution in glycerol.

The next example shows an interior view of the epandrium of a Fannia parva. In the Malinol photo we get a much better idea of how the spiracle shaped bacilliform sclerites are connected to the surstyli. It almost looks like the hinge of a door.

Here we see the right gonites of a Copromyza similis, postgonite is on the left side. The small sensillae with a very fine hair in the middle are almost invisible in glycerol.

This is the right gonostylus of a Exechia festiva. The Malinol photo makes it much easier to disentangle the many little lobes, hairs, and bristles attached to the inner side of the gonostylus.

And finally, to keep the pros and cons in balance, an example where use of Malinol is again questionable, the dorsal view of the hypopygium of a Mycetophila alea, ninth tergite removed.
