Diagnosis. This is one of the largest species of the genus, resembling in size C. hauseri from Bolivia (vide supra) and, also like C. hauseri , has one of the most elongate heads ( Table 2). Females of C. hypermeces are immediately recognizable owing to the large hypostomal lamellae formed on the rostrum (Figs 109–110). While males lack this feature (or have it only very weakly developed), their coloration (Figs 111–113), sternal structure (Fig. 114), and terminalia (Figs 117–118) are immediately distinc- tive. Female coloration, which is similar to the male, also serves to separate them from congeners (Figs 107–110).

Description. Female: Total body length 9.81–9.90 mm; forewing length 6.80– 6.93 mm. Head length 3.07–3.23 mm, width 1.80–1.88 mm. Hypostomal carina enlarged into enlarged lamella in anterior half of head near mandibular base (Figs. 109–110). Clypeus beginning below lower tangent of compound eyes. Malar space 65.2–66% compound eye length (malar length 1.03–1.07 mm; compound eye length 1.57–1.64 mm) (Figs 108–110). Upper interorbital distance 0.86–0.90 mm; lower interorbital distance 0.57–0.63 mm. Upper portion of pronotum medially depressed, slightly elongate, medially less than 0.75 times ocellar diameter in length; ventral portion of preëpisternal sulcus not broad, similar to scrobal sulcus and upper portion of preëpisternal sulcus; intertegular distance 1.41–1.48 mm; mesoscutellum weakly convex, not bigibbous. Basal vein distad cu-a by three times vein width; 1rs-m distad 1m-cu by two times vein width; 2rs-m distad 2m-cu by six times vein width, 2rs-m gently arched; first submarginal cell longer than combined lengths of second and third submarginal cells; second submarginal cell narrowed anteriorly, anterior bor- der of second submarginal cell along Rs slightly shorter than that of third submarginal cell; posterior border of third submarginal cell about two times longer than anterior border. Distal hamuli arranged 2-1-2. Inner metatibial spur with 5–6 branches (not including apical portion of rachis).

Clypeus and supraclypeal area faintly imbricate with weak punctures separated by 1–3.5 times a puncture width; face above level of antennae minutely punctured, punctures separated by less than a puncture width and frequently nearly contiguous, below level of antennae and in malar space punctures slightly more widely spaced; punctures of face blending to smooth integument in ocellocular area and vertex, with smaller punctures separated by 1–2.5 times a puncture width; gena smooth with minute punctures separated by 1–3 times a puncture width; postgena imbricate and impunctate. Pronotum faintly imbricate with scattered minute punctures; mesoscutum smooth with small punctures separated by 0.5–1.5 times a puncture width, puntures weaker anteriorly, blending to imbricate integument anteromedially; mesoscutellum smooth with small punctures separated by 0.5–1.5 times a puncture width; metanotum faintly imbricate with minute punctures separated by 0.5–2 times a puncture width. Preëpisternum smooth with small punctures separated by 0.5–2 times a puncture width; mesepisternum smooth with weak punctures separated by 2–6 times a puncture width; metepisternum faintly imbricate. Propodeum strongly imbricate. Metasoma faintly imbricate.

Mandible amber except reddish at apex; labrum amber; clypeal apex and medially for most of surface amber, basal borders of clypeus dark brown with strong metallic copper highlights; malar space with amber patch near mandibular base otherwise dark brown with strong metallic copper and sometimes green highlights; supraclypeal area dark brown with strong metallic copper highlights; remainder of head metallic copper-green. Antenna light brown except scape amber. Mesosoma metallic copper green (Fig. 107); tegula amber. Wing membranes lightly infumate or yellowed; veins amber except Sc+R brown. Legs amber except coxae, trochanters, and proximal half of metafemur brown with copper green highlights. Metasoma amber except TIII to metasomal apex dark brown with strong metallic copper highlights and translucent amber apical margins; sterna dark brown.

Pubescence golden except slightly more fuscous apically on metasoma.

Male: As described for the female except as follows: Total body length 10.88– 11.70 mm; forewing length 6.80–7.0 mm. Head length 3.15–3.30 mm, width 1.63–1.83 mm. Hypostomal carina not lamellate or only very weakly so anteriorly. Clypeus beginning below lower tangent of compound eyes. Malar space 69.5–70% compound eye length (malar length 1.07–1.10 mm; compound eye length 1.54–1.58 mm) (Figs. 112–113). Upper interorbital distance 0.78–0.83 mm; lower interorbital distance 0.42–0.50 mm. First flagellomere about as long as pedicel, about as long as wide; second flagellomere 3.4 times length of first flagellomere; ventral surfaces of second through eleventh flagellomeres densely covered in placoid sensilla, placoid fields not disrupted. Intertegular distance 1.39–1.50 mm; mesoscutellum not bigibbous, faintly depressed medially. Inner metatibial spur serrate. Apical margin of SIII entire; apical margin of SIV weakly emarginate, margin weakly and broadly produced lateral to emargination, without furrow in apical half of disc (Fig. 114); apical margin of SV entire; apical margin of SVI emarginate; terminalia as depicted in figures 117 and 118.

Mandible and labrum more yellow in coloration; amber mark on clypeus typically extending from apex to only about midlength of clypeus, remainder dark brown with strong metallic copper highlights. Legs typically more yellow than in female. Metasoma with amber in basal third on TIII–V in some males.

Typical gender pilosity except postgena with scattered elongate, sinuate setae, such setae with short apical branches; inner surfaces of trochanters, profemur, mesofemur, and metacoxa with elongate, apically-plumose setae (such setae particularly numerous on protrochanter and base of profemur), similar setae on inner surfaces of metatrochanter, metafemur, and metatibia except largely simple and somewhat sinuate. Apical margin of SIII with fringe of moderate-length golden setae; SIV with small, apicolateral areas of diffuse long golden setae and patches of short, subappressed dense setae bordering medial emargination and extending posteriorly along disc; SV laterally with diffuse areas of long, inwardly-curved setae.

Etymology. The specific epithet is taken from the Greek term hypermekes, meaning “very long”.

Floral record. A male of C. hypermeces was captured at flowers of Psychotria pongoana Standl. (Rubiaceae) in Putumayo, Colombia.
