Derelomus fasciatus Hartmann, 1904 Fig. 19 Derelomus fasciatus Hartmann, 1904: 404. Derelomus fasciatus – Haran et al. 2022a (phylogenetic relationships); 2023a (life history). Diagnosis This species can be distinguished by its narrow body, the pronotum being isodiametric and the elytra elongate (W: L ratio: 0.6), its long and narrow rostrum, longer than the pronotum in lateral view, and simple claws. In most specimens, the dark pattern on the elytra forms a spot at the base of each elytron and a bisinuate transverse strip near the middle of the length. GenBank accession numbers for the corresponding DNA barcodes: OK188823 / OK283507 / ON553434 –35.
