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 : 45-48

Capitonius stramentosura Pitz n. sp.

( Figs. 35 , 36 A–G)

Diagnosis: Distinguishable from other species in the subgenus by the following combination of characters: head rufous and lacking dense, small pits posteroventrally near spiracles on t4–t7.

Length: 8.7 mm.

Color: body melanic except: fore tibia, fore tarsus except apical tarsomere, and apex of ovipositor sheath testaceous; head, except margin around mandible and clypeus tan; wings slightly infuscate ( Fig. 36 G).

Head ( Fig. 36 A–C): antenna with 38 flagellomeres, each with 2–5 rows of longitudinal placodes; vertex with sparse and weak punctures and weak setation laterally; occipital carina with evenly spaced setae over its entirety; lateral carina bordering antennal scrobe incomplete; median lamella of antennal scrobe flattened anteriorly, acute posteriorly; face and clypeus with dense punctures; ventral margin of clypeus with three blunt tubercles.

Mesosoma ( Fig. 36 D–E): anterior margin of pronotum protruding posteriorly as curl of cuticle; pronotum rugosopunctate anteriorly, crenulate medianly and posteriorly; anterior face of mesoscutum punctate to foveate with moderately dense setae; median lobe of mesoscutum triangular; mesoscutum mostly smooth, with moderately dense setae evenly over lateral edges, anterior margin of median lobe carinate laterally and foveate medianly, lateral margins smooth, lateral lobe smooth with fovea and sparse setae laterally; notauli meeting in anterior half of mesoscutum, with transverse carinae that create large oval and rectangular fovea; transscutal articulation not grooved; scutellar disc with moderate weak punctures, with moderately dense long setae; scutellar sulcus with 9 fovea; propleuron with moderate punctation and setae ventrally, becoming foveate dorsally; mesopleuron with carinae running perpendicular to epicnemial area and pleural sulcus with perpendicular carinae ventrally, otherwise mesopleuron smooth with few fovea, with dense setae on anterior margin and on posterior margin ventrally, otherwise with sparse setae; sternaulus complete, restricted to single row of ovoid fovea; propodeum irregularly areolate, with moderately dense to dense setae; metapleuron irregularly areolate with sparse to moderate setae ventrally; hind coxa lacking distinct groove or depression on median face; tarsal claw with basal lobe absent.

Metasoma ( Fig. 36 F): t1 smooth; t4–t7 lacking dense, small pits posteroventrally near spiracles; first valvula of ovipositor with serrations apically; second valvula lacking subapical serration; ratio of length:width of t1 2.8; ratio of ovipositor:forewing 2.2; ratio of M+CU:1M vein of hind wing 2.5.

Variation: some specimens with 33 flagellomeres and smooth median lobe of mesoscutum.

Notes: pinned through mesosoma.

Biology: unknown.

Male: unknown.

Etymology: from the Latin stramentum meaning ivory and sura meaning calf of the leg for the testaceous colored fore tibia.
