A new oligochaete of the family Naididae, subfamily Naidinae, Bratislavia gusevi sp. n., was found in a forest stream in Vietnam. The worm is characterized by small size, asexual reproduction by fragmentation, and dorsal bundles of chaetae beginning from segment II. Each dorsal bundle bears one to two hairs and one to two simple-pointed or bifid, rarely trifid, needle chaetae. An additional distinctive feature of the worm is the presence of one to two enlarged simple-pointed needle chaetae in the bundles of segment IV. These chaetae are somewhat longer and markedly wider than the needles in the rest of the segments. The present paper provides an illustrated description of the discovered individuals and discusses the species systematic position, asexual reproduction and regeneration.
一种新的寡毛目颤蚓科颤蚓亚科的线虫，Bratislavia gusevi sp. n.，在越南的一条森林溪流中被发现。这种蠕虫的特征是体型小，通过碎片进行无性繁殖，以及从第 II 节开始的背束纤毛。每个背束都有一根到两根毛发和一根到两根简单尖的或二分叉的、很少三分叉的针状刚毛。这种蠕虫的另一个显著特征是在第 IV 节的束中存在一到两根增大的简单尖的针状刚毛。这些刚毛比其余部分的针稍长且明显更宽。本文提供了对发现的个体的插图描述，并讨论了该物种的系统位置、无性繁殖和再生。
