The distribution of putative catecholamines has been previously studied in the nervous system of three Promesostoma species using the glyoxylic-acid-induced fluorescence (GAIF) method. In this communication, the results are reported of a similar study of Promesostoma balticum, which is classified to another group of species in the genus. Promesostoma species from two different species groups differed in the position of neurons associated with the ventral and lateral cords. All the studied species of Promesostoma demonstrated doubled dorsal neurons in so called anterior complex (AnDo), a character which differentiates this genus from the other studied Typhloplanoida.
先前已使用乙醛酸诱导荧光（GAIF）方法，对三种前吻涡虫属物种的神经系统中假定的儿茶酚胺分布进行了研究。在本报告中，汇报了对波罗的海前吻涡虫进行的一项类似研究的结果，该物种被归类于该属的另一物种组。来自两个不同物种组的前吻涡虫属物种，在与腹索和侧索相关的神经元位置上存在差异。所有被研究的前吻涡虫属物种在所谓的前部复合体（AnDo）中都显示出双背神经元，这一特征使该属与其他已研究的盲游涡虫目区分开来。
