I added two versions of the same new photo; I wasn't sure which would be more helpful. One is lightened.

that is helpful. Can you also post a view of the entire underside? For females, the key says that the abdominal segments together are helpful in determining species. I do have a few ideas right now though of what this might be.
Is this individual still the same pale color dorsally?

I added a wider crop of the same shot. The specimen was already dead when the ventral pics were taken. It was still just as pale dorsally at that time (and still is). A possibly conspecific female emerged today, as well. I'll try to keep her alive a little longer to see if any color develops.

based on what I can tell, this is C. coma:
- wings lack any markings, yellowish overall
- wings of this female barely reach the tip of the abdomen
- size (within 2.5-2.7 mm)
- abdominal segments are together longer than wide
- pregenital sternite is narrow and more than 2x as wide as long, and is truncated with a very shallow notch; lateral margens are not strongly convergent
- length is 2.5x the width across the eyes (was trying to make it 3x the width, which would have been C. calcaris, but the ruler doesn't lie); tarsi are pale

This species is known from Harris county by the way. If the other female you have is the same, will double check this ID when you rear that one out. The one thing that is lacking is the dark scutellar angles, but those may color with age, not sure. I can kind of see where they would come in on this individual.

Thanks for all the info, Kyle.

since you had a male of this species, I went back and checked out your previous Ceratagallia. Females of both species basically have the same pregenital sternite and morphological features, so the list I probided above applies for females of cristula as well (except size range is 2.3-2.6 mm). The one difference is that the scutellar angles are black in coma; in cristula, only the eye spots are prominent, other markings are obscure (you can see this in the male).

And as I said before, coma is known from the Houston area so you could run into both species.
