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 : 19-21

Capitonius lateventris Pitz n. sp.

( Figs. 13 , 14 A–G)

Diagnosis: Distinguishable from other species in the subgenus by the following combination of characters: head rufous with ventral portion of clypeus and gena melanic, ratio of length to width of t1 1.6, t1 completely melanic.

Length: 6.9 mm.

Color: melanic except: fore tibia and fore tarsus except basitarsus testaceous; head, except gena and clypeus ventrally, rufous; wings slightly infuscate ( Fig. 14 G).

Head ( Fig. 14 A–C): antenna with 31 flagellomeres, each with two to five rows of longitudinal placodes; vertex smooth with sparse setae; 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. 14 D–E): anterior margin of pronotum protruding posteriorly as curl of cuticle; pronotum lightly rugose anteriorly and medianly, crenulate posteriorly; anterior face of mesoscutum foveate; median lobe of mesoscutum triangular; mesoscutum rugosofoveate with strong carinae anterolaterally and moderately dense setae, lateral lobe smooth with sparse setae; notauli meeting in anterior half of mesoscutum, with transverse carinae that create large oval and rectangular fovea; transscutal articulation not grooved; scutellar disc with moderately dense punctures and setae; scutellar sulcus with four fovea; propleuron foveate anteriorly and posteriorly, otherwise with moderate punctures and dense setae; mesopleuron with carinae running perpendicular to epicnemial area, pleural sulcus with few large weakly impressed fovea ventrally and few perpendicular carinae dorsally, mesopleuron otherwise smooth with moderately dense to dense setae anteriorly and posteroventrally; sternaulus complete, restricted to single row of ovoid fovea; propodeum and metapleuron irregularly areolate with moderately dense to dense setae; hind coxa with distinct groove or depression on median face; sharp carina on anterior border of hind coxal groove present; tarsal claw with basal lobe absent.

Metasoma ( Fig. 14 F): t1 with two acute dorsal carinae basally, otherwise smooth; t4–t7 with dense, small pits posteroventrally near spiracles; first valvula of ovipositor with serrations apically; second valvula lacking subapical serration; ratio of length:width of t1 1.8; ratio of ovipositor:forewing 1.6; ratio of M+CU:1M vein of hind wing 2.0.

Variation: substantial variation not observed among specimens examined.

Notes: left forewing broken off, affixed to label; no paratype with complete antennae.

Biology: unknown.

Male: unknown.

Etymology: from the Latin late meaning wide and ventris meaning abdomen in reference to the wide apex of the t1.
