description: Capitonius stramentopetiolus Pitz n. sp.
(Figs. 33, 34 A–G)
Diagnosis: Distinguishable from other species in the subgenus by having the head rufous, clypeus, gena around mouthparts and face below antennal socket melanic.
Length: 8.2 mm.
Color: body melanic except: antenna and head rufous, except clypeus, gena around mouthparts and vertical bands from antennal insertion to gena around mouthparts rufous; base of t1 ivory; wings hyaline (Fig. 34 G).
Head (Fig. 34 A–C): antenna with 34 flagellomeres, each with 2–4 rows of longitudinal placodes; vertex smooth and glabrous; occipital carina glabrous dorsally, with evenly spaced setae over remainder; 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. 34 D–E): anterior margin of pronotum protruding posteriorly as curl of cuticle; pronotum rugosopunctate anteriorly, crenulate medianly and posteriorly, with moderate to dense setae; anterior face of mesoscutum rugose with sparse setae; median lobe of mesoscutum subtriangular; mesoscutum rugose with moderate setae on lateral edges, 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 few fovea, mostly glabrous; scutellar sulcus with 6 fovea; propleuron smooth posteriorly with few fovea anteriorly, with moderately dense setae; mesopleuron with carinae running perpendicular to epicnemial area, pleural sulcus rugosofoveate ventrally, otherwise mesopleuron smooth, with moderate to dense setae anteriorly and posteroventrally; sternaulus complete, restricted to single row of ovoid fovea; propodeum irregularly areolate and foveate with moderately dense setae; metapleuron foveate with moderately 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. 34 F): t1 with light rugosity in basal half, otherwise 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 1.2; ratio of ovipositor:forewing 1.7; ratio of M+CU:1M vein of hind wing 2.6.
Variation: substantial variation not observed among specimens examined.
Biology: unknown.
Male: unknown.
Etymology: from Latin stramento meaning ivory and petiolus meaning petiole for the ivory color at the base of first median metasomal tergum.
Material examined: Holotype. Ψ Piste de Kaw, pk 9; 2 mai 1993 GUYANE; éclos d'un tronçon d'arbre; Gérard TAVAKILIAN leg (FUSAGx).
