Table 2.

Comparative table of measurements (mm) for Euwallacea fornicatior, E. fornicatus, E. kuroshio, and E. perbrevis. Measurements for the total length, pronotal and elytral width, and length/width ratios are measured in the dorsal view, while the pronotal and elytral length are measured in a lateral view on a diagonal, as detailed by Gomez et al. [14].
