Strombidium arenicola Dragesco，1960 年和 Novistrombidium apsheronicum（Alekperov 和 Asadullayeva，1997 年）11 月。梳子。分别使用现场观察、丙二醇浸渍和扫描电子显微镜对地中海和沙特阿拉伯的海水进行了重新描述。首次不仅使用 Protargol 浸渍材料描述了 Strombidiid（即 S. arenicola）的个体发生，而且还通过扫描电子显微照片进行了记录。 Strombidium arenicola 和 N. apsheronicum 具有对映体分裂模式，体细胞纤毛起源于动体运动内增殖后的简单分裂。然而，S. arenicola 和 N. apsheronicum 的口腔原基位置不同，即在带运动体左侧部分的下方和上方。由于Strombidium的个体发生再现了Novisrombidium的右旋带状运动，后者被认为是祖先。通过包括口腔原基的位置，可以使新颤虫属的诊断更加精确。
Strombidium arenicola Dragesco, 1960 and Novistrombidium apsheronicum (Alekperov and Asadullayeva, 1997) nov. comb. are redescribed from marine waters of the Mediterranean Sea and Saudi Arabia, respectively, using live observation, protargol impregnation, and scanning electron microscopy. For the first time, the ontogenesis of a strombidiid, i.e. S. arenicola, is not only described using protargol-impregnated material but also documented by scanning electron micrographs. Strombidium arenicola and N. apsheronicum have an enantiotropic division mode and the somatic ciliature originates by simple division after intrakinetal proliferation of kinetids. The location of the oral primordium is, however, different in S. arenicola and N. apsheronicum, i.e. below vs. above the left portion of the girdle kinety. Since the ontogenesis of Strombidium recapitulates the dextrally spiralled girdle kinety of Novistrombidium, the latter is regarded as ancestral. The diagnosis of the genus Novistrombidium is made more precise by including the location of the oral primordium.
