The ideas of E. G. Racovitza which led to the development of biospelaeology (biospeology, is the term used by Racovitza and adopted here) are reviewed. We emphasize the important research programme named Biospeologica which allowed to implement pract

Taxonomic chimeras, artificial taxa created unintentionally by amalgamation of morphological traits belonging to different taxonomic units, can be found in 19th century to present day scientific literature. We recognise two types of such artefacts in

EMIL G.RACOVITZA supported a Genealogic species concept, expressed as “a colony of isolated consanguines”. The RACOVITZA’s concept considers species as homogenous lineages of organisms which evolve during their history. Description of such enti
