The former can be distinguished by the more dull and muted coloration, the more closely punctured mesoscutum, the distinct arching of 2rs-m in the forewing, the structure of the SIV and terminalia in males (Figs 8, 14–15), and the slightly larger body size. <b>Description.</b> <i>Female</i>: Total body length 8.94–9.43 mm; forewing length 6.37– 6.40 mm. Head length 2.60–2.66 mm, width 1.69–1.77 mm. Clypeus beginning just below lower tangent of compound eyes (Fig. 3). Malar space 34.4–35.8% compound eye length (malar length 0.52–0.53 mm; compound eye length 1.47–1.51 mm) <b>Map Ι.</b> Collection localities for Bolivian <i>Chlerogella</i>. (Figs. 3–4). Upper interorbital distance 0.87–0.89 mm; lower interorbital distance 0.63–0.65 mm. Upper portion of pronotum medially depressed, not elongate, medially less than 0.25 times ocellar diameter in length; ventral portion of preëpisternal sulcus not broad, similar to scrobal sulcus and upper portion of preëpisternal sulcus; intertegular distance 1.38–1.43 mm; mesoscutellum weakly convex, not bigibbous. Basal vein distad cu-a by three times vein width; 1rs-m distad 1m-cu by three 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 not narrowed anteriorly, anterior border of second submarginal cell along Rs about as along as that of third submarginal cell; posterior border of third submarginal cell slightly more than two times longer than anterior border. Distal hamuli arranged 2-1-2. Inner metatibial spur with six branches (not including apical portion of rachis). Clypeus and supraclypeal area imbricate with weak punctures separated by 1–2 times a puncture width; face with small, contiguous punctures, more widely spaced in malar space; punctures of face blending to faintly imbricate integument in ocellocular area and vertex, with punctures separated by a puncture width; gena smooth with small punctures separated by 1–2 times a puncture width; postgena imbricate and impunctate. Pronotum imbricate with minute punctures separated by 1–3 times a puncture width; mesoscutum imbricate with small punctures separated by a puncture width or less on lateral thirds and along posterior border, medially punctures separated by 1–1.5 times a puncture width, anteromedially punctures becoming exceedingly faint to absent; mesoscutellum faintly imbricate with small punctures separated by a puncture width or less; metanotum imbricate with minute punctures separated by a puncture width or less. Preëpisternum faintly imbricate with small punctures separated by 1–3 times a puncture width; mesepisternum weakly imbricate with small punctures separated by 2–6 times a puncture width, punctures weak; metepisternum faintly imbricate. Propodeum strongly imbricate. Metasoma weakly imbricate. Mandible dark brown except reddish at apex; labrum dark brown; clypeal apex black, remainder of clypeus and head dark, dull metallic blue, nearly black in some individuals. Antenna dark brown. Mesosoma dark, dull metallic blue, nearly dark brown or black in some individuals (Fig. 2); tegula dark brown. Wing membranes weakly infumate; veins dark brown. Legs dark brown except apical tarsomeres slightly lighter. Metasoma dark brown, with apical margins of terga translucent brown. Pubescence white to slightly golden except intermingled with fuscous setae on mesoscutum, mesoscutellum, metanotum, TIV–VI, and SIV–VI, and dark fuscous to black on pro- and mesotibiae, pro- and mesotarsi, metatibia, and metatarsus. <i>Male</i>: As described for the female except as follows: Total body length 9.43–9.74 mm; forewing length 6.40–6.53 mm. Head length 2.63–2.67 mm, width 1.61–1.67 mm. Clypeus beginning below lower tangent of compound eyes (Fig. 6). Malar space 45.3–46.1% compound eye length (malar length 0.63–0.65 mm; compound eye length 1.39–1.41 mm) (Figs 6–7). Upper interorbital distance 0.76–0.78 mm; lower interorbital distance 0.45–0.47 mm. First flagellomere about as long as pedicel, about as long as wide; second flagellomere three times length of first flagellomere; ventral surfaces of second through eleventh flagellomeres densely covered in placoid sensilla, placoid fields disrupted by narrow mediolongitudinal line of fine, minute trichoid sensilla for lengths of flagellomeres V–X and apically on flagellomere IV. Intertegular distance 1.33–1.38 mm; mesoscutellum weakly bigibbous. Inner metatibial spur serrate. Apical margin of SIII entire; apical margin of SIV weakly produced medioapically, with narrow concave emargination between setose lobes, with narrow shallow medio-longitudinal furrow in apical half of disc, not bordered by carinae (Fig. 8); apical margin of SV weakly concave; apical margin of SVI emarginate; terminalia as depicted in figures 14 and 15. Mandible, labrum, and clypeal apex white. Areas of dark, dull metallic blue in female darker in male, nearly black and with faint hints of blue (Fig. 5). Typical gender pilosity except postgena with numerous elongate, sinuate setae, such setae with short apical branches; inner surfaces of trochanters, mesofemur, and metacoxa with elongate, apically-plumose setae, similar setae on inner surfaces of metatrochanter, metafemur, and metatibia except largely simple and somewhat sinuate, those of metatibia particularly elongate and sinuous at apices. Apical margin of SIII with diffuse fringe of moderate-length white setae; SIV with small medioapical pads of short golden to fuscous setae bordering medial emargination; SV laterally with diffuse areas of long, inwardly-curved setae. <b>Etymology.</b> The specific epithet is taken from the Department of Bolivia in which the type series was collected.
