( Figs. 1–12 )

DIAGNOSIS: Cleptommation bulivyense is most similar to C. tupaqi , particularly in the structure of the male terminalia and coloration of the mesosoma. The Bolivian species can be distinguished from C. tupaqi by the brown to dark brown metasoma ( Figs. 1–4 , 10, 11 ) and the male genitalia ( Figs. 7–9 ), and from others in the genus by the form of the hidden sterna ( Fig. 6 ) and the coloration of the mesosoma ( Figs. 1–4 , 10, 11 ).

DESCRIPTION: ♂: Total body length 8.44 mm (8.00– 9.13 mm); forewing length 7.33 mm (6.13–7.33 mm). Head length 1.93 mm (1.80–2.00 mm), width 2.27 mm (2.23–2.33 mm; upper interorbital distance 1.17 mm (1.17–1.20 mm); lower interorbital distance 0.83 mm (0.80–0.93 mm). Intertegular distance 1.50 mm (1.47–1.50 mm). Forewing basal vein nearly confluent with cu-a, only slightly set distally; 1rs-m confluent with 1m-cu; 2rs-m distad 2m-cu by 10 times vein width, 2rs-m relatively straight; first submarginal cell longer than combined lengths of second and third submarginal cells; second submarginal narrow, anterior border of second submarginal cell along Rs less than length of third submarginal cell along same vein; anterior border of third submarginal cell about three-quarters length of posterior border; hind wing with distal hamuli arranged 3-1-1-3. Terminalia as in figures 6–9.

Labrum imbricate. Clypeus imbricate with faint, coarse punctures over yellow surface, otherwise smooth with smaller, faint punctures separated by a puncture width or less over basal brown integument; supraclypeal area smooth with small punctures separated by a puncture width or less laterally; remainder of face with small punctures separated by a puncture width or less, progressively becoming more dense on upper face with punctures separated by less than a puncture width; punctures become minute and more widely-spaced by ocellar area, separated by 1–2 times a puncture width in ocellocular area and 2–4 times medially on vertex; gena with punctures like those on vertex; postgena impunctate. Pronotum imbricate with scattered, minute punctures. Mesoscutum smooth with minute punctures separated by 1–2.5 times a puncture width, punctures fainter and sparser along anteromedial border around medial line and integument faintly imbricate; mesoscutellum as on disc of mesoscutum except punctures separated by 1–3 times a puncture width; metanotum smooth, weakly nodulose near setal bases and with punctures separated by 1.5–3 times a puncture width. Preëpisternal area imbricate; mesepisternum with small punctures separated by a puncture width or less, punctures becoming fainter and sparser ventrally and posteriorly; hypoepimeral area impunctate; metepisternum faintly imbricate and impunctate; lateral and posterior surfaces of propodeum weakly imbricate and impunctate; basal dorsal-facing area of propodeum finely imbricate and impunctate. First metasomal tergum smooth, shining, and impunctate; remaining terga finely imbricate; sterna finely imbricate.

Mandible yellow except reddish at apex; labrum yellow; clypeus yellow except basal margins brown with strong metallic brassy green highlights; supraclypeal area entirely brown with strong metallic brassy green highlights. Scape yellow but frequently with slightly brownish patch at upper apical margin; pedicel and flagellum brown. Face, vertex, and gena brown with strong metallic brassy green highlights; postgena brown with faint metallic highlights. Labiomaxillary complex yellow. Pronotum and propleura yellow, sometimes with brownish patches with metallic green highlights on dorsal-facing part of pronotum bordering mesoscutum; remainder of mesosoma brown with strong metallic brassy green highlights, highlights sometimes weaker on disc of mesoscutum, mesoscutellum, metanotum, and dorsal-facing surface of propodeum to varying degrees; preëpisternal area frequently with yellowish area and lower posterior corner of mesepisternum often with patch of yellow; lateral surface of propodeum with large surface of yellow; tegula brown without metallic highlights. Wing membranes hyaline and slightly tinged like parchment; veins amber colored except Sc+R slightly darker. Legs entirely yellow. Metasoma entirely brown ( Figs. 1 , 3, 4 ), sometimes with patch of yellow in anterior portion of first tergum and corresponding sternum.

Pubescence generally yellow; face with particularly prominent short, subappressed, plumose setae which become more sparse toward ocellar area ( Fig. 5 ); vertex with scattered erect, long setae; gena with plumose setae as those on face although not as dense; postgena with sparse, simple, long, erect setae. Mesoscutum with scattered, fine, simple or little-branched, subappressed, yellow setae; with short plumose setae as those on face along lateral borders; mesoscutellum similar to mesoscutum, posteriorly with more elongate and more erect setae; metanotum similar to mesoscutellum although erect setae much more numerous and over entire surface; pleura with scattered yellow setae, becoming longer ventrally; propodeum with setae as on pleura except with dense patches of moderately long, plumose setae around propodeal spiracle. First metasomal tergum with sparse setae over much of surface except fine, suberect, yellow setae becoming more numerous, albeit still widely scattered, in posterior half; remainder of metasomal terga with fine, short, suberect to subappressed setae scattered over surface, becoming progressively more numerous and slightly longer on more apical terga; sterna with scattered, fine, suberect yellow setae, those of apicolateral corners of sterna II–IV typically longer and somewhat more sinuate.

♀: As described for the male except as follows: Total body length 8.53–9.13 mm; forewing length 7.27–7.53 mm. Head length 2.20 mm, width 2.67–2.80 mm; upper interorbital distance 1.37–1.53 mm; lower interorbital distance 1.30–1.43 mm. Intertegular distance 1.57–1.77 mm.

Punctation generally as described for male, although mesepisternal punctures smaller, fainter, and more sparse than those of male, thereby giving mesepisternum a more smooth and shining appearance.

Pedicel and first flagellomere yellowish brown; remainder of flagellum brown. Metasoma entirely brown ( Figs. 10, 11 ) except basal area of first tergum lighter and areas of yellow basally on first and second sterna.

Protibia with minute patch of slightly fuscous setae on outer apex; mesotibia with patch of dark brown to black setae on outer apex ( Fig. 10 ), most setae distinctly curved apically; metatibia with patch of dark brown to black setae on outer apex, patch extending proximally as a thin row of setae to cover about apical one-third of metatibia ( Fig. 10 ), most setae distinctly curved or sinuate apically. Metasomal sterna with scattered, fine, short to long, largely-erect, yellow setae in apical half to third.
