Description. Male. Body length (holotype): 1.9 mm, wing length 2.1 mm. Head: frons and face metallic green, shiny, with some white pruinosity, narrowest distance between eyes about 3 times the distance between ocellar setae; palpus pale yellow; proboscis dark brown; antennal segments black; first flagellomere 1.5 times as high as long, with long hairs; arista dorsoapical, pubescent; lower postocular setae white. Thorax: mesonotum bright metallic green, shiny, with white grey pruinosity; thoracic setae yellow; 5 pairs of strong dc; ac absent; scutellum with pair of strong marginal setae and 2 small lateral setae; 1 strong yellow ppls; pleura metallic green, shiny, with white pruinosity. Legs: entirely yellow including coxae, except tarsomere 5 dark brown, setae and hairs yellow. Fore leg: coxa with some anterior setae; femur, tibia and tarsomeres lacking major setae; tarsomere 5 slightly flattened dorsoventrally; relative podomere ratios: 47: 52: 28: 12: 10: 5: 6. Mid leg: coxa with some anterior and a strong anterolateral seta; femur with a strong anterior preapical seta; tibia with strong ad setae at 1 / 4 and 2 / 3, with small pd seta at 2 / 3, and with 3–4 apical setae; tarsomere 5 slightly flattened dorsoventrally; relative podomere ratios: 52: 66: 36: 15: 10: 6: 6. Hind leg: coxa with strong lateral seta; femur with strong anterior preapical seta; tibia with small ad seta at 1 / 3, with some small dorsal setae, and some apical setae; tarsomere 5 slightly flattened dorsoventrally; relative podomere ratios: 53: 79: 28: 18: 13: 7: 6. Wing: hyaline, veins yellow; basal section of CuA longer than distal section; R 3 + 4 and M parallel and curved posteriad; CuAx ratio: 0.27; RMx ratio: 2.5; lower calypter whitish, with white setae; halter pale yellow. Abdomen: light metallic green, shiny, tergites 1 and 8 yellow; hairs and setae yellow. Hypopygium (Fig. 1 A): epandrium yellow; cercus brown; epandrial lobe basally yellow, apically dark brown, surstylus dark brown. Epandrial lobe long, with oval apex, with 1 strong midventral and 2 smaller apical setae; hypandrium short, truncate; surstylus with strong, subapical seta. Female: unknown.
Distribution
Distribution. Portugal, Spain, Turkey (Naglis, unpubl.).
Etymology
Etymology. The name refers to the southern distribution of the species.
Discussion
Remarks. In the Palaearctic key (Negrobov 1978), C. meridionalis sp. nov. runs to C. molliculus (Fallén, 1823). Males of both species can be separated by the characters given below.
