Myxobolus stanlii sp. n. was described from largescale stonerollers ( Campostoma oligolepis ) from the Mobile River Basin in Alabama. The parasite was described using critical identifying morphological features, and the 18S small subunit ribosomal RNA (SSU rRNA) gene sequence. The spore body was ovoid, 10.03 ± 0.7 (7.5-11.0) μm long and 8.8 ± 1.5 (6.3-11.3) μm wide in frontal view. Spore thickness was 6.3 ± 2.7 (6.2-8.6) μm in sutural view. Polar capsules were pyriform, of equal size, and oriented in plane with the sutural ridge. Polar capsules were 2.45 ± 1.5 (range 2.1-4.3) μm in width and 4.6 ± 2.7 (range 4.5-6.9) μm in length. Based on the SSU rRNA gene sequence of Myxobolus stanlii sp. n. is most closely related to M. pseudodispar.
斯坦利碘泡虫(Myxobolus stanlii)新种是从阿拉巴马州莫比尔河流域的大口石滚鱼(Campostoma oligolepis)中发现并描述的。该寄生虫是利用关键的鉴别形态特征以及18S小亚基核糖体RNA(SSU rRNA)基因序列进行描述的。孢子体呈卵形,正面观长10.03±0.7(7.5 - 11.0)μm,宽8.8±1.5(6.3 - 11.3)μm。缝合面观孢子厚度为6.3±2.7(6.2 - 8.6)μm。极囊呈梨形,大小相等,与缝合嵴在同一平面上。极囊宽2.45±1.5(范围2.1 - 4.3)μm,长4.6±2.7(范围4.5 - 6.9)μm。基于斯坦利碘泡虫的SSU rRNA基因序列,该新种与伪异碘泡虫(M. pseudodispar)关系最为密切。
