A chromosomal analysis of four European species of Aphodius ILLIGER, subgenera Colobopterus MULSANT, Coprimorphus MULSANT, Otophorus MULSANT and Teuchestes MULSANT

The karyotypes of Aphodius (Colobopterus) erraticus (L.), A. (Coprimorphus) scrutator (HERBST), A. (Otophorus) haemorrhoidalis (L.) and A. (Teuchestes) fossor (L.) are described and illustrated. All four species have nine pairs of autosomes and sex chromosomes which are Xy (male) and XX (female). The karyotypes of all four species are distinctive, but the sequence of relative chromosome lengths is strikingly similar in A. erraticus and A. scrutator
