A new coccidian species, Eimeria atricillae n. sp. (Apicomplexa: Eimeriidae) collected from the laughing gull Leucophaeus atricilla, is reported from Port Isabel, Texas, USA. Sporulated oöcysts of the new species are spherical to subspherical, 16.0-18.1 × 14.4-16.6 (17.1 × 15.4) μm, with a length/width (L/W) ratio of 1.0-1.1; polar granules are present, but micropyle and oöcyst residuum are absent. Sporocysts are ovoid, 9.1-9.7 × 6.1-7.1 (9.4 × 6.6) μm, with a L/W ratio of 1.3-1.5; Stieda body present, but sub-Stieda and para-Stieda bodies are absent; sporocyst residuum diffuse.
一种新的等孢球虫，即斑嘴鸭等孢球虫（Eimeria atricillae n. sp.）（顶复门：艾美耳科），从美国得克萨斯州伊莎贝尔港的笑鸥（Leucophaeus atricilla）中分离出来。该新种的孢子化卵囊呈球形至近球形，大小为 16.0-18.1×14.4-16.6μm（17.1×15.4），长/宽（L/W）比为 1.0-1.1；极粒存在，但无卵膜孔和卵囊残余物。孢子囊呈卵圆形，大小为 9.1-9.7×6.1-7.1μm（9.4×6.6），L/W 比为 1.3-1.5；有斯氏小体，但无副斯氏小体和后斯氏小体；孢子囊残余物弥散。
