The females of the geophilomorph centipede Stenotaenia rhodopensis (Kaczmarek, 1970) guard the eggs and young by wrapping their bodies around the brood so that the ventral side is exposed to the outside. This observation confirms the basal division of the Geophilomorpha into Placodesmata (comprising only the family Mecistocephalidae) and Adesmata, which corresponds to the anatomical differences between these groups, especially with regard to the absence or presence of ventral pores, the openings of the ventral glands. We have provided comparative data for some external morphological characters between young and their mothers to clarify changes in taxonomic characters during early post-embryonic development. In addition, we have explained some of the key terms used in the study of the evolution of parental care and identified ecological factors such as harsh environments and predation pressure as possible evolutionary drivers of parental care in centipedes.
Самки геофиломорфной многоножки Stenotaenia rhodopensis (Качмарек, 1970) охраняют яйца и детенышей, обхватывая выводок своим телом так, что брюшная сторона оказывается наружу. Это наблюдение подтверждает базальное деление Geophilomorpha на Placodesmata (семья Mecistocephalidae) и Adesmata, что соответствует анатомическим различиям между этими группами, особенно в отношении отсутствия или наличия вен тральных пор, отверстий вентральных желез. Для выяснения изменений таксономических признаков в период раннего постэмбрионального развития мы предоставили сравнительные данные по некоторым внешним морфологическим признакам детенышей и их матерей. Кроме того, мы объяснили некоторые ключевые термины, используемые при изучении эволюции родительской заботы, и определили эколо гические факторы, такие как суровые условия окружающей среды и давление хищников, как возможные эволюционные движущие силы родительской заботы у многоножек.
