Figure 6. Discovered beetle remains from the Late Glacial Lithuanian outcrops that are currently absent in Lithuania but common in Scandinavia. For Pycnoglypta lurida (A), Arpedium brachypterum (B), Otiorhynchus nodosus (C), and Agabus arcticus (D), the subfossil remains identified in this study, a modern specimen, and the modern distribution according to GBIF [62,63,64,65] are shown. Red crosses indicate the locations from which the subfossil remains were identified.

#LiteratureNotice Haugen et al. Insight Into the Phylogeny of the Intertidal Beetle Genus #Aegialites (Coleoptera, Salpingidae) doi.org/10.1111/zsc.... #Beetle #Beetles #intertidalbeetle
Maximum likelihood (ML) tree for five species of Aegialites from this study, along with Aegialites californicus (OR168935) and two outgroup salpingds. The tree is based on a concatenated alignment of 13 protein-coding mitochondrial genes. GenBank accession numbers for the sequences are provided next to the species names. Posterior probabilities (from BI analysis) and bootstrap values are indicated near the nodes, and a scale bar representing the mean number of nucleotide substitutions per site is located at the bottom. Putative range and species names of specimens are outlined in the coloured boxes, and the colours correspond to colours from the species delimitation analyses as seen in Figure
