Dichotomius valoisae new species (Coleoptera: Scarabaeidae: Scarabaeinae: Dichotomiini) from Santa Luzia do Itanhi, Sergipe, Brazil, is described based on external differences from its congeners. Diagnostic characters and a brief discussion about its conservation status are provided, as well as an updated identification key to the Dichotomius sericeus (Harold) species group.

Transposable elements are dispersed repetitive DNA sequences that can move within the genome and are related to genome and chromosome evolution, adaptation, and speciation. The aim of this study was to characterize and determine the chromosomal location and accumulation of a Mariner-like element in populations of four phylogenetically related species of the Dichotomius (Luederwaldtinia) sericeus complex. Mapping of the isolated element was performed by fluorescent in situ hybridization in different populations of analyzed species.

The Dichotomius sericeus species group of the subgenus Luederwaldtinia is reviewed. This group comprises eight species endemic to the South American Atlantic forests, Caatinga and associated areas of Brazil, Paraguay and Argentina: Dichotomius sericeus (Harold, 1867); Dichotomius irinus (Harold, 1867); Dichotomius laevicollis (Felsche, 1901); Dichotomius schiffleri Vaz-de-Mello, Gavino Louzada, 2001; Dichotomius guaribensis sp. nov.

B chromosomes have so far been described in about 80 species of Coleoptera, mainly using conventional staining analysis. In this study, 152 individuals of the dung beetle Dichotomius sericeus (Coleoptera), collected from three isolated geographical areas in the State of Pernambuco, Brazil, were analyzed to determine the frequency, prevalence, distribution, meiotic behavior, and possible B chromosome origin. The cytogenetic analysis consisted of conventional staining, C-banding, triple fluorochrome staining (CMA3/DA/DAPI), and fluorescent in situ hybridization using ribosomal DNAs (rDNAs) and H3 histone gene as probes, as well as microdissection and chromosome painting of the B chromosome.
