Schrottky's original description of A. amphitrite leaves no doubt about the identity of this species. He mentioned for the female two characters that are diagnostic: the scutellum medially with a longitudinal impression, and the frontal carina not reaching the median ocellus. He also mentioned the characteristic large size (10 mm long), and the sparsely punctate clypeus and later ( Schrottky 1911), mentioned another characteristic feature of A. amphitrite , the rugulose sculpture of the supraclypeal area.

According to the original description of O. thebe , the lost type was a large male (10 mm long) with the first metasomal sternum tuberculate and the scutellum medially depressed. There is only one species of Augochlora in Buenos Aires with this combination of characters, and corresponds to the male of A. amphitrite . All other characters mentioned by Schrottky in the original description of O. thebe also agree with the present species. Moreover, males of A. amphitrite run to O. thebe in the key to species of Odontochlora published by Schrottky two years later ( Schrottky 1911).

In the same work, Schrottky (1911) keyed out males with a spiniform projection on the first metasomal sternum and black hairs on the mesonotum as A. amphitrite . Males of A. amphitrite studied by us have S1 tuberculate, not with a sharp spine, and the hairs on the scutum are at most yellowish brown. We suggest that the male(s) referred to A. amphitrite by Schrottky in that key may correspond to a different species. No species in the studied area has males with a sharp spine on the first metasomal sternum.

Diagnosis. This species is readily distinguished by the scutellum with a median longitudinal furrow in both sexes. The female has the supraclypeal area rugulose between punctures, the frontal carina extends halfway between the upper level of the antennal socket and the median ocellus, the hind tibia and basitarsus have dark brown to black hairs, and T2–T3 with rather broad apical black bands, as long as the diameter of the median ocellus. The male is distinguished by the clypeus with an apical yellowish band or apical lateral marks, the black base of the mandible with a green spot, the entirely dark first flagellomere, and the presence of a more or less developed tubercle on S1.

Female. Length of body 7.7–13.0; length of forewing, 4.7–6.0; maximum width of head, 2.00–3.25; length of head 1.90–2.75; ocello-ocular distance 1.5–2.0 times MOD. Color. Metallic green with some bluish tints, some specimens with golden reflections mainly on face and propodeum; some specimens metallic blue with violet tints. Mandible dark brown with small green spot at base; labrum dark brown to black. Hypostomal area blackish with green tints. Scape, pedicel and first flagellomere black, rest of flagellar dorsal surface dark brown to black and ventral surface paler. Clypeus with black apical band one fifth as long as clypeus. Tegula dark brown with green anterior spot. Legs black, anterior and hind coxae, anterior surface of trochanters, and under surface of forefemur, with green tints. T1–T4 with apical black bands (on T2 0.9–1.0 times MOD), T5 black, sterna black. Wings hyaline with light brown veins and pterostigma.

Mesepisternum with small, dense punctures (0.02–0.05) and shiny interspaces on hypoepimeral area and below scrobal furrow; anterior to mesepisternal furrow areolate-rugulose. Upper part of metapleuron striate. Basal area of metapostnotum entirely striate; striae irregular medially, and regular, parallel, laterally. Disc of T2 with fine shallow punctures (0.02–0.03).

Structure. Frontal carina extending halfway between upper level of antennal socket and median ocellus. Mandible long, distance between base of mandible and starting point of lower apical expansion (outer view), longer than basal width of mandible (1.25–1.45). Apex of clypeus medially depressed. Lateral angle of pronotum forming acute angle. Scutellum with median longitudinal furrow, sometimes reduced to median apical depression. Middle trochanter elongate, with ventral margin straight in lateral view. Hind femur ventrally concave. S1 always with median spine, usually high and sharply pointed, but sometimes low and less pointed.

Male. Length of body 8.5–9.3; length of forewing, 4.7–5.0; maximum width of head, 2.0–2.2; length of head 2.25–2.50; ocello-ocular distance 1.3–2.0 times MOD. Color. Similar to that of female, except as follows: mandible yellowish brown to brown but base black with green spot; labrum yellowish brown; hypostomal area black; clypeus with apical yellowish band, sometimes reduced to lateral marks; scape, pedicel, first flagellomere and base of second black, rest of flagellar dorsal surface dark brown to black and ventral surface paler; coxae, trochanters and femora black with green tints, tibiae and tarsi dark brown; T1–T6 with black apical bands, (on T2 0.75–1.10 times MOD); S1 with blue tints, S2–S6 dark brown.

Clypeus and supraclypeal area with light brown hairs simple, sparser than on other parts of head; on clypeus short (0.04–0.08) and long hairs (0.18–0.20), on supraclypeal area short (0.06–0.07) and long hairs (0.20– 0.22). Setae on mandible white (0.16), on labrum light brown.

Hairs on S1–S6 brown, longer on S2 (0.30).

Sculpture. Clypeus polished, with even, large punctures (0.03–0.05), separated by less than their diameter; supraclypeal area with dense punctures, at sides and on upper part nearly coalescent, on lower part sparser, larger (0.01–0.04). Disc of scutum with close, deep punctures (0.02–0.05), and shiny interspaces. Scutellum with punctures (0.03–0.06) sparser medially, forming at each side of midline shiny area with few punctures. Mesepisternum with dense punctures (0.04–0.05) and shiny interspaces on hypoepimeral area and below scrobal furrow; anterior to mesepisternal furrow areolate-rugulose. Upper part of metapleuron striate. Basal area of metapostnotum entirely striate; striae irregular medially, parallel at sides. Disc of T1–T2 with small punctures (on T2 0.02–0.04), and shiny interspaces; punctation finer on other terga.

Structure. Basal area of labrum proximally smooth, and distally faintly striate; basal area along midline short, approximately one fourth of labral length, on lateral margin not reaching lateralmost setae. Lateral angle of pronotum forming acute angle with pointed tip. Scutellum with median longitudinal furrow, sometimes reduced to median apical depression. S1 with median more or less developed tubercle, variable in size. Basal process of gonostylus reduced, with short setae. Ventral process of gonostylus setose from base to apex, setae as long a diameter of gonostylus; apex of process rounded. Dorsal process of gonostylus with long setae in a row.

Variation. There is variation in color of some specimens from central Argentina, principally from the province of Córdoba, the integument of which is entirely blue, not green. Specimens from Misiones may have bronze or violet tints, mainly on the head. The punctures of the supraclypeal area of the female can be weak in some specimens, but the surface between punctures is always finely rugose. The longitudinal furrow of the scutellum is usually distinct, but in some specimens, particularly in some males, it is reduced to a median depression on the posterior margin of the scutellum. The ventral projection on S1 of the female is always spiniform, although variable in size, and more or less pointed; the projection of the males is usually tuberculiform, but in some specimens it is very low, nearly absent. The variation in size of the projection on S1 is not allometric.

Females of this species present a distinct cephalic polymorphism. Heads of large specimens (13 mm) are disproportionately larger than those of small specimens (7.75 mm). The vertex is swollen behind the eyes, and in frontal view it becomes rather flat, not convex as in smaller specimens. The genae are also enlarged, so the proportion of the maximum width of the gena in lateral view to the maximum width of the eye, increases in larger specimens. Values taken on ten females reprentative of the various sizes observed among studied specimens (maximum width of the eye-maximum width of gena: 0.48–0.45; 0.51–0.48; 0.51–0.66; 0.57–0.45; 0.57–0.69; 0.60–0.72; 0.63–0.90; 0.66–0.90; 0.66–0.96; 0.75–1.05) give a coefficient of allometry of 1.75. This coefficient is close to the coefficient for A. iphigenia (approximately 1.9), which can be calculated from the data presented by Sakagami & Moure (1965).
