Diagnosis. Among darker species from Central America, C. pinocchio can be distinguished by the metallic dark hunter green integument of the head and mesosoma (Figs 33–35) and the combination of unmodified metasomal sterna III–V with an entirely yellow scape and pedicel, pale yellow clypeal apex, and yellow protibia and tarsi (except metabasitarsus largely brown).

Description. Male: Total body length 8.37 mm; forewing length 5.24 mm. Head length 2.57 mm, width 1.40 mm. Base of clypeus below lower tangent of compound eyes. Malar space 53% compound eye length (malar length 0.70 mm; compound eye length 1.33 mm). Upper interorbital distance 0.70 mm; lower interorbital distance 0.33 mm. First flagellomere about as long as pedicel, about as long as wide; second flagellomere 2.8 times length of first flagellomere; ventral surfaces of second through eleventh flagellomeres densely covered in placoid sensilla, placoid fields disrupted by relatively broad mediolongitudinal line of fine, minute trichoid sensilla for lengths of flagellomeres V–IX, at base and apex of flagellomere IV and basal half of flagellomere X. Intertegular distance 1.0 mm; mesoscutellum bigibbous. Basal vein distad cu-a by three times vein width; 1rs-m distad 1m-cu by four times vein width; 2rs-m distad 2m-cu by six times vein width, 2rs-m weakly and gently arcuate; first submarginal cell longer than combined lengths of second and third submarginal cells; second submarginal cell not narrowed anteriorly, anterior border of second submarginal cell along Rs slightly longer than that of third submarginal cell; posterior border of third submarginal cell about 2.5 times longer than anterior border. Distal hamuli arranged 2-1-2. Inner metatibial spur serrate. Apical margins of metasomal SIII–V entire; apical margin of SVI emarginate; terminalia as depicted in figures 40 and 41.

Clypeus and supraclypeal area weakly imbricate with weak punctures separated by 1–3.5 times a puncture width; face smooth with small punctures separated by a puncture width, such punctures more widely spaced in malar space, approximately 1–2.5 times a puncture width, integument between faintly imbricate; ocellocular area and vertex smooth with even more minute punctures separated by 2–5 times a puncture width; gena smooth with minute punctures separated by 2–6 times a puncture width; postgena imbricate and impunctate. Pronotum smooth with minute punctures separated by 2–5 times a puncture width; mesoscutum smooth with minute punctures separated by 2–5 times a puncture width; mesoscutellum and metanotum sculptured as on mesoscutum. Preëpisternum and mesepisternum smooth with minute punctures separated by 3–6 times a puncture width; metepisternum faintly imbricate. Propodeum strongly imbricate. Metasoma weakly imbricate.

Mandible, labrum, and clypeal apex pale yellow; remainder of clypeus dark brown with metallic green highlights; remainder of head metallic green, turning slightly blu-

ish on vertex and gena; scape and pedicel yellow, flagellum dark brown. Mesosoma dark metallic hunter green; tegula translucent light brown. Wing membranes hyaline; veins brown except Sc+R darker. Legs brown to dark brown except protibia and tarsi (excluding large basal portion of metabasitarsus) yellow, with light brown to yellowish brown areas around podite articulations. Metasoma brown, blending gradually to dark brown by apex; metasomal T1 with small medial yellowish brown spot.

Pubescence generally golden; typical gender pilosity except postgena with numerous elongate setae, such setae with a few short apical branches; inner surfaces of trochanters, mesofemur, metacoxa, metatrochanter, and metafemur with elongate setae, such setae apically with a few short branches; similar setae on inner surface of metatibia except largely simple and of moderate-length. Metasomal sternal discs with sparsely scattered, short, simple, erect setae; apical margin of metasomal SIII with diffuse line of moderate-length, apically-curved setae, such setae slightly more numerous and longer laterally; SIV with apicolateral areas of diffuse short, appressed, inward-directed setae; SV without setal modifications.

Female: Unknown.

Etymology. The specific epithet is a noun in apposition and refers to the fictional wooden doll, Pinocchio, famed for his inveracity and impudence and whose nose grew with each falsehood ( Collodi 1883). Th e name alludes to the elongate rostrum that is shared between this species and its namesake.

Comments. The head of the holotype, and only known specimen, is detached and was mounted by someone in the past on a small point beneath the body. Otherwise the specimen is in excellent condition.
