Maccaffertium mexicanum
It is difficult with just a dorsal view to clearly indicate a species concept. However this has the bald spots on the abdomen as in Maccaffertium intergrum. Yours has the black spots in the middle of abdominal segments 1-4 and 6th with black lateral spots on the 7th. This aligns with Allen and Cohen 1977 figure 14 for true M mexicanum. How this should be listed is Maccaffertium mexicanum / intergrum. So change the title to that and Roger with change it if needed.
