Parental care is a character that shows enormous diversity both within and between different animal taxa and is an important topic in evolutionary biology and behavioural ecology. In centipedes (Chilopoda), parental care includes relatively simple forms of care such as egg attendance and offspring attendance. As in most geophilomorphs, the females of Geophilus serbicus Stojanović, Mitić and Antić in Stojanović et al, 2019; Henia illyrica (Meinert, 1870); Pleurogeophilus herzegowinensis (Verhoeff, 1901); Stenotaenia linearis (C. L. Koch, 1835); Stenotaenia rhodopensis (Kaczmarek, 1970); Strigamia herzegowinensis (Verhoeff, 1935); and Schendyla carniolensis Verhoeff, 1902 are wrapped around the eggs or juveniles and have at least part of the trunk in an S-curve. Most of the trunk is orientated so that the dorsal side faces the brood and the ventral side faces outwards. This observation confirms the basal division of the Geophilomorpha into Placodesmata (to which only the family Mecistocephalidae belongs) 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. The dichloromethane extracts of the ventral gland secretion of G. serbicus contain three volatile compounds: benzaldehyde, methyl 2-phenylacetate and benzoyl cyanide. A species new to science (G. serbicus), the description of which is part of this dissertation, is clearly distinguished from its congeners by a unique combination of morphological characters. Te early development of G. serbicus can be divided into three phases: embryonic (eight embryonic stadia), early postembryonic or embryoid (stadia proembryoid I, II and III, peripatoid and foetus) and adolescens (stadium adolescens I).

Briga o potomstvu je ponašajni karakter koji pokazuje ogromnu raznovrsnost unutar i između različitih životinjskih taksona i predstavlja važnu temu u evolucionoj biologiji i ponašajnoj ekologiji. Kod stonoga iz klase Chilopoda, briga o potomstvu obuhvata relativno jednostavne oblike ponašanja kao što su briga o jajima i briga o mladima. Kao i kod većine geofilomorfa, ženke vrsta Geophilus serbicus Stojanović, Mitić i Antić u Stojanović et al., 2019; Henia illyrica (Meinert, 1870); Pleurogeophilus herzegowinensis (Verhoeff, 1901); Stenotaenia linearis (C. L. Koch, 1835); Stenotaenia rhodopensis (Kaczmarek, 1970); Strigamia herzegowinensis (Verhoeff, 1935); i Schendyla carniolensis Verhoeff, 1902 su sklupčane oko jaja ili mladih tako da im je bar deo trupa u obliku slova „S”. Najveći deo trupa je dorzalnom stranom okrenut ka leglu, a ventralnom stranom ka spolja. Ovo zapažanje potvrđuje bazalnu podelu Geophilomorpha na Placodesmata (obuhvata samo porodicu Mecistocephalidae) i Adesmata, što odgovara anatomskim razlikama između ovih grupa, posebno u pogledu odsustva ili prisustva ventralnih pora — otvora ventralnih žlezda. Dihlormetanski ekstrakt sekreta ventralnih žlezda vrste G. serbicus sadrži tri isparljiva jedinjenja: benzaldehid, metil 2-fenilacetat i benzoil cijanid. Nova vrsta za nauku (G. serbicus), čiji je opis deo ove disertacije, od bliskih srodnika se razlikuje po jedinstvenoj kombinaciji morfoloških karaktera. Rano razviće vrste G. serbicus može se podeliti u tri faze: embrionalnu (osam embrionalnih stadijuma), ranu postembrionalnu ili embrioidnu (stadijumi proembrioid I, II i III, peripatoid i fetus) i adolescens fazu (stadijum adolescens I).
