description: <i>Chlerogella anthonoma</i> Engel, sp. n. urn:lsid:zoobank.org:act: 783629FA-13EA-475A-80D2-E8DFD90375C9 Figs 30–32, 38, 39; Map 2 <b>Holotype.</b> ♁, CoSTA RICA: San José, Braulia Carville [sic] N.P., 400m, 10–11 April 1983, H. Goulet, tropical rainforest (AEI). <b>Diagnosis.</b> This species is related apparently to <i>C</i>. <i>kellieae</i> described above (<i>vide supra</i>) as evidenced by the similar overall structure, body proportions, and genitalia. <i>Chlerogella anthonoma</i> can be distinguished by the combination of an amber mesosoma with only the mesoscutum dark metallic green (resembling in this respect <i>C</i>. <i>elongaticeps</i>) (Fig. 30), the clypeus more extensively marked with amber (cf. Figs 25 vs. 31), the slightly more elongate head (Figs 31, 32), the entirely golden setae of the inner surface of the metabasitarsus, the entirely amber metasoma, the greatly reduced second submarginal cell, and the structure of the terminalia (Figs 38, 39). <b>Description.</b> <i>Male</i>: Total body length 8.36 mm; forewing length 5.68 mm. Head length 2.80 mm, width 1.53 mm. Base of clypeus at lower tangent of compound eyes. Malar space 58% of compound eye length (malar length 0.83 mm; compound eye length 1.43 mm). Upper interorbital distance 0.73 mm; lower interorbital distance 0.30 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 mediolongitudinal line of fine, minute trichoid sensilla for lengths of flagellomeres V– VIII, those on flagellomeres V and VI medially constricted, and at base and apex of flagellomere IV. Intertegular distance 1.17 mm; mesoscutellum weakly bigibbous. Basal vein distad cu-a by two times vein width; 1rs-m distad 1m-cu by two times veins width; 2rs-m distad 2m-cu by seven times vein width, 2rs-m relatively straight; first submarginal cell longer than combined lengths of second and third submarginal cells; second submarginal cell narrowed anteriorly, anterior border of second submarginal cell along border with Rs about one-quarter that of third submarginal cell; posterior border of third submarginal cell about 1.3 times as long as anterior border. Distal hamuli arranged 2-1-2. Inner metatibial spur serrate. Metasomal sterna III–IV unmodified, with apical margins straight; apical margin SVI emarginate; terminalia as in figures 38 and 39. Clypeus and supraclypeal area faintly imbricate, with weak punctures separated by 1–3 times a puncture width, more sparse medially. Head above level of antennae smooth with small punctures separated by a puncture width or less, below level of antennae and in malar space with minute punctures separated by 1–3 times a puncture width, integument faintly imbricate; punctures of face becoming more minute and separated by 1–3 times a puncture width in ocellocular area, on vertex and gena; postgena strongly imbricate and impunctate. Pronotum smooth to faintly imbricate. Mes- oscutum smooth, with minute punctures separated by 2–4 times a puncture width, anteriorly punctures become weaker and integument weakly imbricate; mesoscutellum sculptured as on mesoscutum; metanotum smooth with minute punctures separated by 2–5 times a puncture width. Pleura smooth with minute punctures separated by five times a puncture width or more. Propodeum imbricate. Metasoma weakly imbricate. Mandible, labrum, clypeal apex, and area in malar space bordering mandible amber; apical third of clypeus amber, remainder dark brown with strong metallic green highlights; remainder of head metallic green with copper highlights, blending to a bluish cast on vertex. Scape and pedicel yellow, remainder of antenna dark brown. Mesosoma amber except mesoscutum metallic green with copper highlights. Wing <b>Figures 30–32.</b> Holotype male of <i>Chlerogella anthonoma,</i> sp. n. <b>30</b> Lateral habitus <b>3Ι</b> Facial aspect <b>32</b> Lateral aspect of head. membranes lightly infumate; veins brown except Sc+R dark brown. Legs amber. Metasoma amber, with thin transverse brands of amber-brown apically on TI–III. Pubescence golden; typical gender pilosity except postgena with numerous elongate setae, such setae with a few short apical branches; inner surface of metafemur with several long, apically-branched setae, similar setae on inner surface of metatibia except largely simple; metasomal sterna with scattered, short, suberect to erect, simple setae, setae more numerous apicolaterally on SIV and SV. <i>Female</i>: Unknown. <b>Etymology.</b> The specific epithet is the Greek term <i>anthonomos</i>, meaning “feeding on flowers”.
