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 : 26-27

Capitonius robertsonae Pitz n. sp.

( Figs. 19 , 20 A–G)

Diagnosis: Distinguishable from other species in the subgenus by having t1 ivory basally and apically with melanic between.

Length: 7.0 mm.

Color: melanic except: mid and hind trochanter, as well as mid and hind coxa, orange; base and apex of t1 ivory; wings hyaline ( Fig. 20 G).

Head ( Fig. 20 A–C): antenna with 37 flagellomeres, each with two to four 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. 20 D–E): anterior margin of pronotum protruding posteriorly as curl of cuticle; pronotum lightly rugose anteriorly, moderately foveate medianly, crenulate posteriorly; anterior face of mesoscutum rugose; median lobe of mesoscutum triangular; mesoscutum smooth with strong carinae anterolaterally, lateral lobe smooth; notauli meeting in anterior half of mesoscutum, with transverse carinae that create large oval and rectangular fovea; transscutal articulation slightly grooved medianly; scutellar disc smooth with moderate setae; scutellar sulcus with eight fovea; propleuron smooth with few fovea anteriorly and posteriorly; mesopleuron with carinae running perpendicular to epicnemial area, pleural sulcus rugose ventrally with few perpendicular carinae dorsally, otherwise mesopleuron with few elongated fovea, with dense setae anteriorly and posteroventrally; sternaulus complete, restricted to single row of ovoid fovea; propodeum irregularly areolate with moderately dense setae; metapleuron with moderately dense large fovea dorsally and with irregular areolae ventrally with moderately dense setae; hind coxa lacking distinct groove or depression on median face; tarsal claw with basal lobe absent.

Metasoma ( Fig. 20 F): t1 smooth without dorsal carinae; 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 3.3; ratio of ovipositor:forewing 2.2; ratio of M+CU:1M vein of hind wing 2.3.

Variation: substantial variation not observed among specimens examined.

Notes: right flagellomere incomplete, left flagellomere broken but complete.

Biology: unknown.

Male: unknown.

Etymology: in honor of Dr. Marianne Robertson, whose guidance led me to entomology and whose support has been unending.

Material examined: Holotype. Ψ BRAZIL Rondonia, 62 km SE Ariquemes, 7–18 Nov 1995, W.J. Hanson ( EMUS).
