Diagnostic BIN: BOLD:AAW2207. Genbank JQ575483 . Holotype ♀ : Guanacaste , Sector Pitilla , Sendero Memos , 740 meters, Latitude :10.98171, Longitude : -85.42785, caterpillar collection date: 05/16/2016 , wasp eclosion date: 05/28/2016 , 43 wasps eclosed from 43 cocoons. Host data: Gregarious parasitoid of Dyscophellus phraxanor (Hesperiidae) feeding externally on mature leaves of Virola sebifera (Myristicaceae) ( Fig. 2 ). Caterpillar and holotype voucher codes: 16-SRNP-30739, DHJPAR0059752. Paratypes : Host = Dyscophellus phraxanor : 42 specimens same data as holotype and four others reared from this same species of caterpillar and with the same biology: DHJPAR0034233, DHJPAR0041706, DHJPAR0051918, DHJPAR0054658 . Etymology: Acgorium felipechavarriai is named in honor of Felipe Chavarria in recognition of his thousands of hours managing the detailed field accounting for ACG GDFCF projects and specifically for the parataxonomists program, while creating generously public and magnificent drone images of landscapes and camera images of ACG biota. The holotype and paratypes will be deposited in the Canadian National Collection along with others of this same ACG rearing/inventory programme.
