In 2023, on iNaturalist, this Cylindrogaster was observed. The only species known for the region is Cylindrogaster gracilis, which possibly occurs in Peru according to Steinmann (1986). But the description of C. gracilis doesn't fit with this specimen, since the pronotum is not clearly longer than broad and has no incurved lateral margins. It is probably an undescribed species.
