Is this spider poisonous? Looks like a black widow?

Hi, welcome to Spider ID. 🙂 There’s not enough detail in the image for me to be certain if it’s a Widow (Latrodectus sp.) or not, but it does look like a possibility! It looks like you have her in a glass or plastic container? If you can look underneath her abdomen and see a red mark it is a Widow.

I don’t know without seeing it more clearly, or seeing the ventral. The juveniles tend to be lighter with stripes and spots so probably not a juvenile. Another possibility is a False Widow (Steatoda sp.).

Is it a red mark/pattern, or does the whole underside look slightly red? A noble false widow might have a faint red or purple tinge, but not the distinct red hourglass exclusive to widows. ☺

In the mid section (at the bottom of the cephalothorax and on the top of the abdomen) it looks like a slight red tint to it’s skin, not a hour glass shape or dark red in color like the picture shows. Unfortunately it had died due to low oxygen and there is now some brown liquid draining from the its abdomen. Its still in the bottle and i am still observing it.
