Karyotype analysis of four jewel-beetle species (Coleoptera, Buprestidae) detected by standard staining, C-banding, AgNor-banding and CMA3/DAPI staining
Abstract. The male karyotypes of Acmaeodera pilosellae persica Mannerheim, 1837 with 2n=20 (18+neoXY), Sphenoptera scovitzii Faldermann, 1835 (2n=38–46), Dicerca aenea validiuscula Semenov, 1895 – 2n=20 (18+Xy(p)) and Sphaerobothris aghababiani Volkovitsh et Kalashian, 1998 – 2n=16 (14+Xy(p)) were studied using conventional staining and different chromosome banding techniques: C-banding, AgNOR-banding, as well as fluorochrome Chromomycin A(3) (CMA(3)) and DAPI. It is shown that C-positive segments are weakly visible in all four species which indicates a small amount of constitutive heterochromatin (CH). There were no signals after DAPI staining and some positive signals were discovered using CMA(3) staining demonstrating absence of AT-rich DNA and presence of GC-rich clusters of CH. Nucleolus organizing regions (NORs) were revealed using Ag-NOR technique; argentophilic material mostly coincides with positive signals obtained using CMA(3) staining

A new Aphodius species of the subgenus Amidorus Mulsant & Rey, from Armenia (Coleoptera, Aphodiidae)
The new species Aphodius (Amidorus) rollandi n. sp. is described from the high mountains of Armenia. This species is illustrated and compared with related taxa. Some etho-ecological data are reported on Amidorus species.Une nouvelle espèce d'Aphodius d'Arménie du sous-genre Amidorus Mulsant & Rey (Coleoptera, Aphodiidae). Des recherches récentes effectuées dans les montagnes d'Arménie ont permis la découverte d'une nouvelle espèce, Aphodius (Amidorus) rollandi n. sp. L'espèce est décrite, illustrée et comparée aux espèces voisines. Quelques données éco-éthologiques sur les Amidorus sont également fournies.Kalashian Mark, Lumaret Jean-Pierre.
