I suspect that this mirid is Pycnoderes vanduzeei
, based on The Plant Bugs, or Miridae (Hemiptera: Heteroptera), of Cuba
, but I haven't obtained a firm confirmation yet. I'll update this if the relevant expert weighs in. Specimen identified to genus by Susan Halbert (DPI). Any thoughts are welcome.
Adults and nymphs were found on Commelina diffusa
