Pitz, Kevin M., 2010, New taxonomic status of Foenomorpha Szépligeti as a subgenus of Capitonius Brullé (Hymenoptera: Braconidae: Cenocoeliinae) including a revision of species, Zootaxa 2607, pp. 1-54 : 15-19

Capitonius flavusassumentum Pitz n. sp.

( Figs. 11 , 12 A–G)

Diagnosis: Distinguishable from other species in the subgenus by the following combination of characters: forewing infuscate with yellow patch around stigma.

Length: 9.1 mm.

Color: body rufous except: head, antenna, hind tibia and tarsus, propleuron, anterior margin of pronotum, and ovipositor sheath melanic; forewing infuscate with yellow patch around stigma; hind wing infuscate ( Fig. 12 G).

Head ( Fig. 12 A–C): antenna with 30 flagellomeres, each with two to four rows of longitudinal placodes; vertex with sparse and weak punctures and weak setation laterally; occipital carina with evenly spaced setae over entirety; lateral carina bordering antennal scrobe incomplete; median lamella of antennal scrobe completely acute, without flattened area; face and clypeus with moderate punctures; ventral margin of clypeus with one sharp median tooth.

Mesosoma ( Fig. 12 D–E): anterior margin of pronotum protruding posteriorly as curl of cuticle; pronotum mostly smooth with raised area along midline that is triangular from dorsal view; anterior face of mesoscutum smooth; median lobe of mesoscutum triangular; mesoscutum smooth, with moderately dense setae evenly over surface, anterior margin of median lobe smooth over entirety, lateral lobe smooth with sparse setae; notauli meeting in posterior half of mesoscutum, smooth, with weak or no transverse carinae; transscutal articulation not grooved; scutellar disc with sparse to moderate weak punctures and sparse to moderately dense long setae; scutellar sulcus with five fovea; propleuron with sparse to moderate punctation and setae; mesopleuron smooth, episternal area with weak crenulations ventrally, pleural sulcus crenulate creating large oval fovea, dorsal margin with one large depression that does not reach anterior or posterior margins, with sparse to moderate setae on anterior, ventral, and posterior margins, otherwise with sparse setae; sternaulus incomplete, restricted to single row of ovoid fovea; propodeum smooth anteriorly and laterally, irregularly areolate otherwise, with sparse setae; metapleuron smooth with sparse setae; hind coxa with distinct groove or depression on median face; sharp carina on anterior border of hind coxal groove absent; tarsal claw with basal lobe present.

Metasoma ( Fig. 12 F): t1 with short dorsal carinae ending just beyond base of tergite, otherwise smooth; t4–t7 with dense, small pits posteroventrally near spiracles; first valvula of ovipositor with serrations apically; second valvula with one subapical serration present; ratio of length:width of t1 2; ratio of ovipositor:forewing 1.7; ratio of M+CU:1M vein of hind wing 3.8.

Variation: some specimens with 28 flagellomeres and smooth median lobe of mesoscutum.

Biology: unknown.

Male: unknown.

Etymology: from the Latin flavus meaning yellow and Latin assumentum meaning patch, for the yellow surrounding the stigma in the forewing.
