A new species of the bee genus Chlerogella from Panama (Hymenoptera: Halictidae) Author Engel, Michael S. text Zootaxa 2003 286 1 4 journal article 10.5281/zenodo.156350 5f538222-ebce-4947-8e50-4d8e7bcc0528 1175­5326 156350 Chlerogella clidemiae Engel , sp. nov. ( Figs. 1­3 ) Type material: holotype , Ψ, PANAMA : San Blas: 19km N of El Llano, 350m , 31 January 1985 , G. de Nevers, on flowers of Clidemia crenulata [deposited in the Snow Entomological Collection, Division of Entomology, Natural History Museum, University of Kansas, Lawrence, Kansas, USA ]. Diagnosis. The new species is most similar to C . elongaticeps but differing by the more elongate malar space (see description), more widely spaced mesoscutal punctures (punctures separated by a puncture width in C . elongaticeps ), and greater number of metatibial spur teeth (three in C . elongaticeps ), mesoscutum light brown with faint copper highlights (dark brown with strong metallic green­copper highlights in C . elongaticeps ), and light brown to amber flagellum (brown to dark brown in C . elongaticeps ). Description. As described for the genus (see Engel, 2000 ), with the following specific details: Total body length 9.08 mm ; forewing length 5.6 mm . Head length 3.04 mm , width 1.58 mm . Clypeus beginning below lower tangent of compound eyes. Malar space 68% compound eye length (malar length 1.04 mm ; eye length 1.52 mm ) [malar space only 25% compound eye length in C . elongaticeps ]. Upper interorbital distance 0.8 mm ; lower interorbital distance 0.5 mm . Intertegular distance 1.32 mm . Basal vein distad cu­a by 3 times vein width; 1rs­m distad 1m­cu by 2 times vein width; 2rs­m distad 2m­cu by 5 times vein width, 2rs­m relatively straight. First submarginal cell longer than second and third combined; second cell not narrowed anteriorly, anterior border of second as long as that of third; posterior border of third cell approximately twice as long as anterior border. Distal hamuli arranged 2­1­2. Inner metatibial spur with 5 teeth (excluding apex). FIGURES 1­3. Photomicrographs of Chlerogella clidemiae Engel , sp. nov. (holotype). 1, lateral habitus of holotype; 2, frontal view of head; 3, lateral view of head. Clypeus and supraclypeal area smooth with weak punctures separated by 1­2 times width; head smooth with minute punctures separated by 1­2 times width. Postgena imbricate. Pronotum smooth; mesoscutum smooth with minute punctures separated by 1­2 times width, punctures becoming faint along anterior border; scutellum and metanotum as on mesoscutum except punctures not faint anteriorly. Pleura smooth with minute punctures separated by 2­6 times width. Propodeum faintly imbricate. Metasomal terga and sterna faintly imbricate. Mandible amber with red apex. Labrum amber. Clypeal apex and apical half of malar space amber, remainder brown with a few copper highlights laterally; supraclypeal area brown with copper highlights; head dark brown. Scape and pedicel amber, flagellum light brown. Pronotum, mesoscutum, scutellum, and basal area of propodeum brown with faint copper highlights, remainder of mesosoma amber; tegula amber. Wings lightly yellowed; veins amber. Legs amber. Metasoma amber. Pubescence golden. Etymology. The specific epithet is derived from Clidemia , the genus of flowers upon which the holotype was captured. Floral records. The holotype of this species was collected on inflorescences of Clidemia crenulata Gleason (Melastomataceae) , a wide ranging shrub in Central America . Acknowledgements.
