Chromosomal diversification of diploid number, heterochromatin and rDNAs in two species of Phanaeus beetles (Scarabaeidae, Scarabaeinae)
The genus Phanaeus is included in the tribe Phanaeini, one of the most diverse tribes within the subfamily Scarabaeinae in terms of chromosomal characteristics. However, so far the species of this genus were not studied with differential cytogenetic techniques, limiting any inference of the probable mechanisms responsible for this diversity. In this work, several techniques were applied with th...

متن کاملA new diploid chromosome number in Gymnopleurus Illiger, 1803 (Coleoptera: Scarabaeidae, Scarabaeinae) from Haryana, India
The chromosomes obtained from scarab beetle Gymnopleurus mundus Wied., 1819 of subfamily Scarabaeinae were studied using standard staining and C-banding. The karyotype is comprised of 14 chromosomes with meioformula, 6AA+Xyp. The analysis of constitutive heterochromatin (CH) revealed small blocks located in the centromeric region of all chromosomes. Some of the anomalies like polypoidy, deconde...
