Ashe, R. Brooks, Z. Falin, ex: flight intercept trap (SEMC). <b>Paratypes.</b> CoSTA RICA: 1&amp;female;, Est. Carrillo, 700m, P.N. Braulio Carrillo, Prov. S.

Rodríguez (INBio). <b>Diagnosis.</b> <i>Chlerogella kellieae</i> can be distinguished by the metallic green color of the head and mesosoma (Figs 24–29), the metasoma that is extensively marked with yellow in the male (Fig. 24) and amber in the female (Fig. 27), the malar space that is slightly less than one-half the compound eye length (table 1), and the structure of the male terminalia (Figs 36, 37). <b>Description.</b> <i>Male</i>: Total body length 8.93 mm; forewing length 6.40 mm. Head length 2.80 mm, width 1.67 mm. Base of clypeus at lower tangent of compound eyes. Malar space 48% of compound eye length (malar length 0.73 mm; compound eye length 1.52 mm). Upper interorbital distance 0.76 mm; lower interorbital distance 0.40 mm. First flagellomere about as long as pedicel, about as long as wide; second flagellomere 3.2 times length of first flagellomere; ventral surfaces of second through eleventh flagellomeres densely covered in placoid sensilla, placoid fields disrupted by narrow <b>Figures 24–26.</b> Holotype male of <i>Chlerogella kellieae,</i> sp. n. <b>24</b> Lateral habitus <b>25</b> Facial aspect <b>26</b> Lateral aspect of head. mediolongitudinal line of fine, minute trichoid sensilla for lengths of flagellomeres V– VIII, at base and apex of flagellomere IV and basal half of flagellomere IX.

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 five times vein width, 2rs-m relatively straight; 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 border with Rs about as long as that of third submarginal cell; posterior border of third submarginal cell about twice as long <b>Figures 27–29.</b> Paratype female of <i>Chlerogella kellieae,</i> sp. n. <b>27</b> Lateral habitus (note that apparently dark- er areas on the metasoma are due to discoloration of shriveled internal tissues visible through the somewhat translucent terga, the metasomal coloration is otherwise amber) <b>28</b> Lateral aspect of head <b>29</b> Facial aspect. as anterior border. Distal hamuli arranged 2-1-2. Inner metatibial spur serrate. Metasomal sterna III–IV unmodified, with apical margins straight except for a minute median emargination on SIV; apical margin SVI emarginate; terminalia as in figures 36 and 37. Clypeus and supraclypeal area weakly imbricate, with weak punctures separated by 1–3 times a puncture width. 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 2–5 times a puncture width in ocellocular area, on vertex and gena; postgena strongly imbricate and impunctate. Pronotum smooth to faintly imbricate. Mesoscutum smooth, with small punctures separated by 1–2.5 times a puncture width, anteriorly punctures become weaker and integument weakly imbricate; mesoscutellum sculptured as on mesoscutum; metanotum smooth with minute punctures separated by 2–3 times a puncture width.

Propodeum imbricate. Metasoma weakly imbricate. Mandible, labrum, clypeal apex, and area in malar space bordering mandible yellow; remainder of clypeus dark brown with strong metallic green highlights; remainder of head metallic green with copper highlights. Scape and pedicel yellow, remainder of antenna dark brown. Mesosoma metallic green with copper highlights except pronotal lobe yellow and small amber-brown patch posteriorly on mesepisternum; tegula translucent yellow. Wing membranes lightly infumate; veins brown except Sc+R dark brown. Legs largely yellow with extensive brown on hind legs except metatarsus beyond the metabasitarsus and on outer surfaces of pro- and mesotibiae. Metasoma largely brown with yellow markings laterally and basally and as a thin transverse band on TII–V and laterally and mediodorsally on TI; TVI largely yellow-brown; sterna largely yellow except brown markings apically on SIII–V, faint medially on SI. Pubescence generally golden except darkly fuscous on inner surface of metabasitarsus; typical gender pilosity except inner surface of metafemur with several long, apically-branched setae; metasomal SIV with diffuse apicolateral areas of appressed, short, inwardly-directed setae, intermingled with longer erect to suberect, simple setae; SV with diffuse apicolateral lines of short, erect to suberect, largely simple setae. <i>Female</i>: As described for the male except as follows: Total body length 8.89 mm; forewing length 6.33 mm. Head length 2.83 mm, width 1.60 mm. Base of clypeus at lower tangent of compound eyes. Malar space 46% of compound eye length (malar length 0.73 mm; compound eye length 1.60 mm). Upper interorbital distance 0.80 mm; lower interorbital distance 0.53 mm. Antenna not so modified as in male, as in figure 29. Upper portion of pronotum 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 1.40 mm; mesoscutellum weakly convex, not bigibbous. Distal hamuli arranged 2-1-2. Inner metatibial spur pectinate, with four or five branches (not including apical portion of rachis). Mandible brown, with reddish apex; labrum brown; clypeal apex brown, remain- der of clypeus brown with strong metallic green-copper highlights; remainder of head dark metallic green with copper highlights. Scape ventrally yellow, dorsally brown, pedicel yellow-brown, remainder of antenna dark brown. Legs largely brown with amber around podite articulations and on tarsi except metabasitarsus. Metasoma amber to reddish amber (note that apparently darker areas in figure 27 are due to discoloration of shriveled internal tissues visible through the somewhat translucent terga). <b>Etymology.</b> The specific epithet is a matronym honoring my loving and supporting wife, Mrs. Kellie K. Magill Engel. <b>Comments.</b> One of the females attributed to this species was captured near the type locality for <i>C</i>. <i>anthonoma</i> (<i>vide infra</i>) and at some distance from the Guanacaste records for the holotype and other female paratype. Nonetheless, the San José Province female has the same proportions as the Guanacaste female, same sculpturing, same coloration, and similar wing venation as to the holotype and other paratype. They are clearly conspecific and I feel confident that the San José specimen is not the unknown female for <i>C</i>. <i>anthonoma</i> which is clearly a separate species as evidenced by its wing venation, head proportions, and male terminalia.
