Legs. Hind femur length = 0.52 mm; hind femur length/width = 3.00; hind tibia length/hind femur length = 1.19. Fore telotarsus shorter in length than fore basitarsus, telotarsus not modified and with two thick setae at distal edge of ventral area; mid leg tarsal claws with a long and narrow basal tooth; hind telotarsus lacking in the specimen studied.

Hind wing: 1M length = 0.35 mm; 1M length/2M length = 1.22; 1M length/M+CU length = 1.55; length r-m/length cu-a = 1.50; 1RSa length/2r-m = 1.33; 1A length = 0.10 mm.

Metasoma. First tergum basal width = 0.16 mm; first tergum length/distal width = 2.72; second tergum length/distal width = 0.42; third tergum length/distal width = 0.52. First metasomal tergum with a “T” shaped carination inside posterior medial tergum depression, the depression is carinate at edges, anterior basal 1/3 with longitudinal lineate sculpture at lateral areas and mid posterior area, remainder of tergum with confused rugulose like sculpture except for most of mid 1/3 with transversal ridges; second metasomal tergum with costulae sculpture at junction area with third tergum, remainder of tergum with confused and very poorly defined smooth lineate sculpture, remainder of terga nitid.

Material examined. Holotype, male, “ USA, Missouri, Lincoln Co., Cuivre River , S[tate]. P[ark]., [Col.] R. J. Marquis, 10 June 2001, Site: C. River, ID#C.218, em. 10/vii/2001, [larva feeding on] Quercus alba , 891.”

Holotype deposited at INHS.

Comments. This species is described from one known male; however, the presence of a complete areola in combination with an open areolet and the presence of a midlongitudinal depression on distal 1/2 of first metasomal tergum place this specimen clearly within the genus Parapanteles . In addition, the propodeum is not extensively rugose as in the genus Pholetesor . This is the only known species that exhibits semicircular carinae crossing the anterior 1/3 of the midlongitudinal carina.

The holotype lacks the tarsomeres of one hind leg and the other hind leg lacks the telotarsus.

Rearing records. The only known specimen was reared from Chionodes fuscomaculella (Gelechiidae) feeding on Quercus alba (Fagaceae) .

Etymology. Gender, Masculine. This species is named after Abraham Lincoln and the county in which it was collected in Missouri.
