Colletes flaminii Moure, 1956: 203; Pérez & Cerda 1980: 100; Toro 1986: 122, 1999: 27; Moure & Urban 2002: 9; Moure et al. 2007: 681; Montalva & Ruz 2010: 21; Ascher & Pickering 2017.
Holotype ♀ (examined). {DZUP}.
Diagnosis. Colletes flaminii is similar to C. atripes, C. bicolor, and C. fulvipes, however, it is unique in having the following combination of characteristics: mesepisternal interspaces imbricate (interspaces smooth in C. bicolor), tibiae dark-brown to black (tibiae pale-orange in C. fulvipes), and metasoma metallic blue (metasoma black in C. atripes).
Redescription. FEMALE (Figs. 24A, 24C, 24E): Dimensions (mm): Approximate body length 9.2–9.9; head width 3.6–3.9; head length 2.6–2.8; intertegular distance 3.0–3.3; forewing length 6.8–7.2.
Colouration: Black except reddish-brown on distal half of tarsal claws; marked on distal half of mandible. Pale-brown on tibial spurs, medio and distitarsi, proximal half of tarsal claws, tegula, wing veins (except vein R and those enclosing marginal cell dark-brown). Dark-brown on anterior surface of trochanters and femora, dorsal surface of basitarsi, stigma, S6. Metallic dark-blue (with purple and blueish-green reflections) on metasoma (except T6 black).
Structure: Labrum medially convex; convexity not margined by ridges. Clypeal mid-longitudinal area evenly narrowly (0.3x MOD) and shallowly depressed on upper 3/4; adjacent lateral convex; apicomedial ridge present. Malar area 1.4x as long as basal depth of mandible (42:30). F1 1.4x as long as its apical width (42:30). UID:LID (81:73). Genal area concave behind upper summit of compound eyes in lateral view. Dorsolateral angle of pronotum triangular acute. Horizontal surface of metapostnotum ~0.35x as long as metanotum (18:50); metapostnotal pits poorly and irregularly delimited; posterior transverse carina sinuous and broadly interrupted medially. Posteromedial surface of front coxa bearing long spine (0.6x MOD). Posterior hind tibial spur ciliate. Hind basitarsus ~ 3x longer than broad (65:22). Inner rami of tarsal claws absent. Posterolateral area of S6 flat and lacking carina; marginal zone depressed.
Pubescence: Black, plumose, erect, long on lateral slopes of clypeus and supraclypeal area, interantennal, paraocular and genal areas, mesepisternum, metepisternum, mid and hind coxae, posteroventral surface of front trochanter, ventral surface of mid trochanter, T1, S1; such hairs very long on upper margin of lateral surface of propodeum, ventral surface of hind trochanter and femur; moderately short on disc of T2. Interocellar area and pronotal lobe with mixed off-white and black, plumose, erect, long hairs. Ferruginous, plumose, erect, moderately long on mesoscutum, scutellum, metanotum. Black, erect, moderately long setae on mandible, front coxa, dorsal surface of front tibia and basitarsus, dorsal surface of mid and hind tibiae and basitarsi, T3 laterally, T4–T5, S3–S5; such hairs very long on posterior margin of mid and hind basitarsi. Pale-yellow, suberect, very long hairs, which are branched only apically on anterior surface of hind femur and tibia. Pale-yellow, suberect, thick setae on ventral surface of mid and hind tarsi; thickest towards distal margin. S2 with pale-yellow, erect, moderately short hairs, which are branched only apically.
Surface sculpture: Clypeal mid-longitudinal depression densely and moderately finely punctate; adjacent convex area longitudinally striate; lateral slopes smooth. Supraclypeal area impunctate and imbricate. Malar area substrigulate on lower 1/4; costulate elsewhere. Lower paraocular area punctures crowded. Upper paraocular and frontal areas densely and moderately finely punctate, interspaces imbricate and dull. Vertexal area finely and moderately densely punctate (interspaces smooth); coarser and denser towards lateral ocellus (interspaces rugulose). Mesoscutum, scutellum, and mesepisternum moderately finely and densely punctate (except moderately sparsely punctate on mesoscutal mid-posterior area and scutellar anterior margin); interspaces imbricate (except smooth on mesoscutal posterior 2/3 and rugulose on scutellar posterior margin). Metanotal densely and moderately finely punctate; interspaces imbricate. Metepisternum rugose above; obliquely striate medially; areolate below. Lateral surface of propodeum imbricate. Upper area of vertical surface of metapostnotum imbricate medially. Metasoma finely and densely punctate (except sparsely punctate on S6); interspaces smooth (except imbricate on metasomal imbricate).

Range. Argentina (Río Negro, Chubut, Santa Cruz), Chile (Regions VII–XII). See also Fig. 19C.
Biogeographic distribution. Andean region: Central Chilean sub-region (Santiagan province); Subantarctic sub-region (Magellanic Forest province); Patagonian sub-region (Patagonian province). Central Chilean and southwestern Argentinean species distributed at altitudes of 100–2200m a.s.l.
DNA barcode. Available. BOLD: AAO3445 (2♀♀1♂). Barcoded specimens from Chile and Argentina were assigned the same BIN (see Table 1). Distance from the nearest neighbours: 2.8–3.13% (C. fulvipes) and 6.1– 6.12% (C. chusmiza).
Floral hosts. Compositae— Taraxacum campylodes G. E. Haglund [Pérez & Cerda 1980 (as T. officinale (L.) Weber ex F. H. Wigg.)]. Lamiaceae— Nepeta racemosa Lam. [Pérez & Cerda 1980 (as N. mussinii Spreng. ex Henckel)]. Leguminosae— Adesmia sp. (this paper); Trifolium sp. (Pérez & Cerda 1980).
Comments. Uncommon species with a broad geographic range in southern South America. As far as the data suggest, its activity period spans from November to February.
Moure’s description of C. flaminii was based on a single female with weakly pigmented pubescence and integument, which, according to Toro (1999), was probably a recently emerged specimen from the nest. The male was only described several decades later (Toro 1999: 28). This species was not included by Rojas & Toro (1993) in their key for the Chilean species with metallic blue metasoma.
