Capitonius sarmientoi Pitz n. sp.

(Figs. 25, 26 A–G)

Diagnosis: Distinguishable from other species in the subgenus by having t1 melanic with testaceous apex.

Length: 9.0 mm.

Color: body melanic except: fore tibia and tarsus and apex of t1 testaceous; hind and mid coxa and trochanter orange; wings slightly infuscate (Fig. 26 G).

Head (Fig. 26 A–C): antenna with 39 flagellomeres, each with 2–4 rows of longitudinal placodes; vertex with sparse 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. 26 D–E): anterior margin of pronotum protruding posteriorly as curl of cuticle; pronotum weakly rugosopunctate anteriorly, with moderate punctation and setae medianly and crenulate posteriorly; anterior face of mesoscutum with sparse punctures; median lobe of mesoscutum triangular; mesoscutum smooth with sparse setae, anterior margin of median lobe carinate laterally and smooth medianly, 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 moderately dense long setae; scutellar sulcus with 8 fovea; propleuron with moderate punctation and setae ventrally becoming foveate dorsally; mesopleuron with carinae running perpendicular to epicnemial area and to dorsal half of pleural sulcus, otherwise mesopleuron mostly smooth with few fovea, with moderate setae ventrally and dense setae anteriorly and posteroventrally; sternaulus complete, restricted to single row of ovoid fovea; propodeum irregularly areolate, with moderately dense setae; metapleuron foveate dorsally and irregularly areolate ventrally with sparse to moderate setae; hind coxa lacking distinct groove or depression on median face; tarsal claw with basal lobe absent.

Metasoma (Fig. 26 F): t1 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 3.0; ratio of ovipositor:forewing 2.3; ratio of M+CU:1M vein of hind wing 2.3.

Variation: some specimens with mid and hind trochanter melanic, antenna with 36–39 flagellomeres.

Biology: unknown.

Male: unknown.

Etymology: in honor of Carlos Sarmiento-Monroy for his unselfish help with my research over many years.
