Capitonius venustus Pitz n. sp.

(Figs. 39, 40 A–G)

Diagnosis: Distinguishable from other species in the subgenus by having mid tibia rufous.

Length: 8.3 mm.

Color: body rufous except: flagellomere segments 7–32, apex of mandible, metasomal terga 2–9 melanic; wing yellow basally and lightly infuscate apically (Fig. 40 G).

Head (Fig. 40 A–C): antenna with 35 flagellomeres, each with 2–5 rows of longitudinal placodes; vertex smooth with sparse setae; occipital carina with evenly spaced setae over its entirety; lateral carina bordering antennal scrobe complete to lateral ocellus; 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. 40 D–E): anterior margin of pronotum protruding posteriorly as curl of cuticle; pronotum lightly rugosofoveate anteriorly, crenulate medianly and posteriorly; anterior face of mesoscutum with moderately dense fovea and setae; median lobe of mesoscutum triangular; mesoscutum with large fovea along anterior margin with 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 slightly grooved medianly; scutellar disc smooth with moderately dense setae; scutellar sulcus with 4 fovea; propleuron smooth posteriorly, becoming moderately foveate anteriorly, with moderately dense setae; mesopleuron with carinae running perpendicular to epicnemial area, pleural sulcus with few perpendicular carinae, rugose ventrally, otherwise mesopleuron smooth, with moderate setae anteriorly and posteroventrally; sternaulus complete, restricted to single row of ovoid fovea; propodeum irregularly areolate with sparse to moderately dense setae; metapleuron irregularly areolate with sparse to moderately dense setae; hind coxa with distinct groove or depression on median face; sharp carina of anterior border on hind coxal groove present; tarsal claw with basal lobe absent.

Metasoma (Fig. 40 F): t1 with dorsal carinae extending from base over one-third of length, 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 1.4; ratio of ovipositor:forewing 1.3; ratio of M+CU:1M vein of hind wing 2.5.

Variation: antenna with 36–38 flagellomeres.

Biology: unknown.

Male: unknown.

Etymology: from Latin venustus meaning like Venus, lovely, beautiful, elegant, or graceful, named in honor of my wife, Kristina Pitz, and for the beauty of this species.
