D. %A Ortu£¿o %A V. M. %J Animal Biodiversity and Conservation %D 2012 %I The Natural Science Museum of Barcelona %X We provide information for the first time on the larval morphology of Carabus (Oreocarabus) guadarramus La Fert¨¦¨CS¨¦nect¨¨re, 1847, a species endemic to the Iberian peninsula. A detailed iconography is also provided. Three main diagnostic features are given which are particularly relevant to the goal of providing a useful and practical tool to help differentiate between the first instar larvae of this species and the related Carabus (Oreocarabus) ghilianii La Fert¨¦¨CS¨¦nect¨¨re, 1847, which lives in syntopy with C. guadarramus. Detailed maps with 10 x 10 km UTM of the geographic distribution of both species are provided in order to highlight their different chorology. Some of the possible environmental causes that might affect its current distribution are discussed. %K Captivity breeding %K Chaetotaxy %K Competition %K Endemic species %K Iberian peninsula %K Larval morphology %U http://abc.museucienciesjournals.cat/files/ABC_35-1_pp_13-21.pdf
