奥戈氯蜜蜂表现出大量的觅食和社交行为、巢穴基质和建筑。行为的巨大多样性常常与形态特征相关。应该分析所有级别的变异，以便提供更广阔的进化视野。 Augophora (Augophora) 安菲特里特 Schrottky 产于阿根廷北部至巴西东南部。该物种在腐烂的木材中筑巢，具有兼性社会性。文献中已经提到了颜色变异和头部多态性，本文的主要目的是评估物种的形态变异。为此，我们检查了 720 个标本，并使用传统形态测量学进行了定性和定量分析。对其他 25 个 Augochola 物种进行了研究，我们提出了对 Amphitrite 的修订诊断。描述了一种显着的颜色变化，有三种变形：绿色、深蓝色和黑色。没有与颜色变化相关的地理模式。我们认为 Odontophora Lethe Schrottky 和 Odontophora styx Schrottky 是 Odontophora amphitrite Schrottky 的初级同义词。这些名字指的是 A. amphitrite 分布区中出现的黑人男性和女性。头部的大小和形状不断变化。同样，我们没有发现形态与分布的任何关系。除了下颌肿胀外，巨头雌性的下颌骨内收肌脊也非常发达。由于变异表明，A. amphitrite 是一种候选蜜蜂，可作为形态、功能和行为之间联系的研究模型。
Augochlorine bees exhibit a large array of foraging and social behaviors, nest substrates and architecture. The huge diversity of behaviors is frequently linked with morphological traits. All levels of variation should be analyzed in order to provide a broader view of evoluton. Augochlora (Augochlora) amphitrite Schrottky occurs from northern of Argentina to southeastern of Brazil. The species nests in decaying wood and is facultatively eusocial. Color variation and head polymorphism were already mentioned in the literature and the main goal of the present paper is to evaluate the morphological variation of the species. For this purpose, we examined 720 specimens and carried out qualitative and quantitative analyses with traditional morphometrics. Other 25 Augochlora species were studied and we propose a revised diagnosis for A. amphitrite. A remarkable color variation is described, there are three morphs: green, dark blue, and black. There are no geographical patterns linked with the color variation. We propose that Odontochlora lethe Schrottky and Odontochlora styx Schrottky are junior synonyms of Odontochlora amphitrite Schrottky. Those names refer to black male and female occurring within A. amphitrite distribution. There is a continuous variation on size and shape of head. Again, we do not fi nd any relation of morphology with distribution. Besides gena swelling, the adductor ridge of mandible is strongly developed on macrocephalic females. Due variations showed, A. amphitrite is a bee candidate to be a model for studies to link morphology, function and behavior.
