Type specimen. Female holotype from ECUADOR, Napo: Cosanga , 2400 m, 2 Sep 2024, J. Vlasak leg. ( MZSP, formerly JVCO) .

Etymology. The name “ chartreusosus ” is derived from the French word “ chartreuse ” for yellow-green color (from the color of the herbal liqueur Chartreuse) with Latin suffix “ osus ” meaning “full of.” It refers to the yellow-green pubescence on the pronotum and the elytra.

Remarks. As we only have one specimen at our disposal, it is not possible to know whether the species has a wider geographic distribution, or whether it is restricted to the mountainous regions east of the Andes.
