DESCRIPTION: Female. Mandible with moderate to strong subapical tooth. Labral distal process broadly triangular; basal elevation transverse; teeth absent. Prementum not greatly elongate. Galeal apex rounded; galeal comb present; galeal base extending about half of distance to stipital base. Hypostomal fossa as long as wide or wider; hypostomal ridge carinate; anterior angle rounded. Malar space length less than mandibular width. Epistomal sulcus obtuse. Ocelli not greatly enlarged; ocellar furrow absent. Vertex not expanded or ridged behind ocelli. Preoccipital ridge rounded. Pronotal lateral angle not produced, obtuse; dorsal ridge carinate; lateral ridge rounded. Mesoscutal anterior border rounded; mesoscutal lip round- ed. Tegula oval. Anterior basitarsal brush present. Apex of marginal cell acute. Distal hamuli with irregular spacing pattern. Propodeal pit set into notch. Male. Mandible simple. Labrum without distal process; basal are not notched. Antennae long, extending back to propodeal triangle; F2 much longer than F1, usually longer than or as long as scape. Inner hind tibial spur serrate. Meta- soma petiolate. Apical margins of S4 and S5 unmodified. Apical margin of S6 emarginate. Apical margin of S7 unmodified. Apical margin of S8 with median projection; spiculum broad. Proctiger unmodified. Gonobasal bridge broad; dorsal lobes weak. Basal process of gonostylus present; parapenial lobe absent; dorsal gonostylus reduced, present as a ridge bearing setae. Ventral surface of penis valve with keel. Subgenus Callistochlora Michener Figures 28 , 61 , 77 Callochlora Moure, 1964: 269 . Type species: Halictus chloris Spinola, 1851 , original designation. Nomen praeoccupatum ( nec Callochlora Packard, 1864 [ Lepidoptera : Bombycidae ]). Callistochlora Michener, 1997: 12 . Nomen novum pro Callochlora Moure, 1964 . Type species: autobasic with Callochlora Moure, 1964 . DIAGNOSIS: Refer to Diagnosis for Corynura s.s. (below). DESCRIPTION: As for the genus with the following additions: Female. Compound eyes with long eye hairs. Basitibial plate rimmed posteriorly, anterior border obsolete. Inner hind tibial spur pectinate. Basal area of propodeum striate. Male. Basal process of gonostylus without setae. REVISIONS: Moure and Hurd (1987) list four species included in Callistochlora (as Callochlora ); however, two of these have since been moved to other genera (Engel, 1996c). These taxonomic changes have left the subgenus with only the two originally included species, C . chloris (Spinola) and C . prothysteres (Vachal) , both of which can be identified by Moure’s key (1964). BIOLOGY: The nesting biology and mature larva of C . chloris were studied by Claude- Joseph (1926, as a species of Halictus ). DISTRIBUTION: Callistochlora occurs in Chile and Argentina , with one record of C . prothysteres from Peru . Subgenus Corynura Spinola s.s. Figures 14 , 21, 24–26 Corynura Spinola, 1851: 296 . Type species: Corynura gayi Spinola, 1851 [= Halictus rubellus
