Halictus codion Vachal, 1904: 125

Neocorynura codion View in CoL ; Moure, 1944: 69 (taxonomic position as Neocorynura View in CoL ) Diagnosis. Specimens of Neocorynura codion View in CoL can be distinguished from other species of Neocorynura View in CoL by their unique color pattern (i.e., body largely dark brown, gena completely metallic and broad basal bands on T2 to T5) and by the strongly sulcate base of propodeum (in other species, the base of the propodeum is mostly striate). This species can be distinguished from N. tangophyla sp. nov. by the integument of the clypeus (mostly smooth) and the completely metallic green pronotum and metanotum (in N. tangophyla the integument is mostly dark brown).

Redescription: Female (lectotype, designated by Moure 1944). Body length 9.5 mm; forewing length 7.8 mm. Head width 2.2 mm, length 2.1 mm. Scape longer than combined lengths of F1 to F6; F10 longer than preceding flagellomeres; F2 slightly longer than F1. Clypeus wider than long; paraocular lobe semi-obtuse (≈ 110°). Mesoscutum slightly wider than long; metanotum more than half length of mesoscutellum. Mesotibial spur serrate and more than half length of mesobasitarsus; inner metatibial spur pectinate with five teeth, the last two slightly fused. Marginal cell semi-truncate; 1m-cu confluent with 1rs-m; 2m-cu basad 2rs-m by approximately four times vein width; first submarginal cell as long as combined lengths of second and third submarginal cells; second submarginal rectangular; anterior border of second submarginal cell as long as anterior border of third submarginal cell; pterostigma large, margin in marginal cell convex; hamuli spaced 4- 1-1-2 along anterior margin of hind wing. Basal area of propodeum sulcate and longer than mesoscutellum. Metasoma semi-petiolate (slightly longer than wide).

Labrum weakly striate, with small, more or less narrow central process. Clypeus imbricate along margins, slightly imbricate elsewhere, with very coarse punctures separated by less than 1 PD; supraclypeal area imbricate with punctures smaller and more widely distributed (1.5–2.0 PD); rest of face densely punctate; integument adjacent to inner ocular margin imbricate; gena and postgena smooth with small, faint punctures and striate. Scape imbricate, with minute punctures separated by about 1.5 PD. Pronotum mostly smooth with faint punctures; propleura imbricate. Mesoscutum densely punctate, punctures coarse and contiguous, integument between punctures imbricate; mesoscutellum smooth and densely punctate. Metanotum smooth, densely punctate, punctures of different diameters. Pleura strongly punctate with a rugose appearance, integument between punctures strongly imbricate. Tegula faintly imbricate. Basal area of propodeum smooth between sulci.

Mandible brown, tip hyaline and edges black. Labrum dark brown; clypeus black, with some metallic green reflections near epistomal sulcus; supraclypeal area dark brown with metallic purple reflections; subantennal areas, frons and vertex dark brown, area adjacent to eye margins metallic green. Mesosoma dark brown to black except pronotum metallic green; metanotum, margins of mesoscutum, and mesoscutellum metallic green; scrobe metallic blue. Legs mostly dark brown except last three tarsomers. Metasoma dark brown, except T1, with basal area metallic green; bases of T2–T4 with metallic, basal bands as wide as metanotum; T5 metallic green except around pygidial plate.

Scape mostly with minute brown, poorly branched setae sparsely distributed. Vertex with coarse, dark brown setae 1.0 OD in length and sparsely distributed; gena with light brown setae, 0.5–1.0 OD in length, densely distributed; postgena with light brown, branched setae, 1.0–2.5 OD in length, sparsely distributed.

Type material. PERU: Marcapata (without additional information, but with an identification label as Halictus codion by Vachal). In 1958, Moure labeled this female specimen as the Lectoholotype; this specimen was later confirmed and labeled as such by Moure and Hurd (1987: 221) and is deposited in the MNHN. I compared it with the material on loan from Argentina and Paraguay listed below.

Examined material. ARGENTINA: Misiones, Iguazú. X-10-1950. M. Senkate Coll. (1 Ƥ SEMC). PARAGUAY: Alto Paraguay, Puerto Bertoni. XII-1908. A de W. Bertoni Coll. (1 3 AMNH); Junction: Iguaçu & Paraná R. [Rivers]. 1-1-1968 G.E. Bohart Coll. (1 Ƥ BBSL).

Additional records. Smith-Pardo (2005a) also identified additional material of this species from the following provinces or states: BRAZIL: Rio de Janeiro, São Paulo, Santa Catarina, and Paraná; BOLIVIA: La Paz, Santa Cruz, Chapare; ECUADOR: Pastaza and in PERU: Tingo María, Cusco, Pasco and Marcapata (type locality). Moure (2007) lists only Peru and Bolivia as distribution for this species.
