Capitonius rondoniaensis Pitz n. sp.

(Figs. 21, 22 A–G)

Diagnosis: Distinguishable from other species in the subgenus by the following combination of characters: head rufous, hind coxa lacking distinct groove or depression on median face, dense, small pits posteroventrally near spiracles on t4–t7 present, antenna with 36 flagellomeres.

Length: 7.8 mm.

Color: melanic except: head with ventral margin of clypeus and gena, rufous; wings slightly infuscate (Fig. 22 G).

Head (Fig. 22 A–C): antenna with 36 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. 22 D–E): anterior margin of pronotum protruding posteriorly as curl of cuticle; pronotum rugose anteriorly, with moderate fovea medianly, crenulate posteriorly; anterior face of mesoscutum with moderately dense punctures; median lobe of mesoscutum triangular; mesoscutum with sparse to moderately dense setae and carinae anterolaterally, 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 smooth with sparse setae; scutellar sulcus with eight fovea; propleuron foveate anteriorly otherwise with moderate punctures and setae; mesopleuron with carinae running perpendicular to epicnemial area, pleural sulcus rugose ventrally and smooth with few perpendicular carinae dorsally, otherwise mesopleuron with few fovea, with dense setae anteriorly and posteroventrally; sternaulus complete, restricted to single row of ovoid fovea; propodeum irregularly areolate with dense setae; metapleuron irregularly areolate with moderately dense setae ventrally and dense setae dorsally; hind coxa lacking distinct groove or depression on median face; tarsal claw with basal lobe absent.

Metasoma (Fig. 22 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 2.3; ratio of M+CU:1M vein of hind wing 2.1.

Variation: fore tibia testaceous on paratype female.

Notes: left antenna broken, with 12 remaining flagellomeres.

Biology: unknown.

Male: unknown.

Etymology: named for the province in Brazil from which the two known specimens of this species were collected.
