ABSTRACT The first detailed description of early development of the recently described European geophilid Geophilus serbicus is presented. Based on specimens from a natural population from the Balkan Peninsula, new insight was gained into the reproductive and developmental biology of the group. Changes in the morphology of brooded specimens allow 15 early developmental stages obligatorily dependent on prolonged maternal care, arranged in three phases (embryonic, embryoid, and adolescent) to be distinguished. The embryonic phase includes eight stages, followed by an intermediate stage of hatching, followed in turn by five embryoid stages and one adolescens stage. Detailed morphological descriptions of all stages are provided. Adolescens I is recognized as the first stage at which species and sex identification are possible. Besides the description of the earliest stages, we provide notes on reproductive behaviour and ecological features of the species.

巴尔干半岛蜈蚣Geophilus serbicus（Chilopoda：Geophilomorpha：Geophilidae）的早期发育

摘要 首次详细描述了最近描述的欧洲嗜地菌 Geophilus serbicus 的早期发育。基于来自巴尔干半岛自然种群的标本，对该群体的生殖和发育生物学有了新的认识。育雏标本形态的变化允许区分 15 个必须依赖长期母体护理的早期发育阶段，分为三个阶段（胚胎、胚状体和青春期）。胚胎期包括八个阶段，然后是孵化的中间阶段，依次是五个胚状期和一个青春期。提供了所有阶段的详细形态描述。Adolescens I 被认为是物种和性别鉴定可能的第一阶段。
