Returning again to the Ant ID section of the forum for these two different species. After taking a closer look at these queens, I noticed that one was darker in color, and had slightly larger eyes than the other. My guesses for these two species would be: C. Vermiculata (Darker one), and C. Coarctata (Lighter one). I checked on the AntWiki on both those species, and it said that they were hard to differentiate, other than the worker's thoraxes. Nothing was said about differentiating between queens. 

 

(Same length for both species)

 

Queen Length: 9mm

Worker Length: 3-4mm 

 

Location: Mojave Desert, Nevada 

Date: July 9 (Same date caught for both species)

 

 

Queen 1: Crematogaster cf. Vermiculata?

Coloration: Head, and thorax: Dark red. More on the brown side. Abdomen: Black. Legs: Dark Red. 

Worker Coloration: Head and Abdomen: Dark Black. Thorax: Light brown. Legs: Light to dark brown (top to bottom) Jaws: Light Brown

Of the few Crematogaster species that are found in Nevada, I'm almost entirely sure that these species are the correct ones, but I would like other's opinions as well. Thank you for reading this far.
