In this study, we describe M. kubotai lineage 1 as a new species, M. affinis sp. nov., and recognize lineage 2 as the true representative of M. kubotai. This classification is based on morphological observations of the pronotal surface structure, which is a character traditionally used for species identification within the genus. Additionally, we identified morphological differences between M. affinis and M. tetramorii. Furthermore, we developed a non-invasive identification method to distinguish M. affinis and M. tetramorii based on the relative lengths of three pairs of setae on the tenth abdominal tergite.

This method significantly improved pupation success compared to the artificial diet alone (21.68%) and demonstrated higher pupation efficiency relative to labor input than the conventional raw plant-based rearing. Notably, some final instar larvae appeared to have pupated without feeding on the plant material, suggesting that non-nutritive cues—possibly chemical signals from the plants—may trigger pupation.

The hydrocarbon components in the frass are derived from the larval cuticle. This method can detect larval species regardless of tree species, the passage of time, or larval age. However, we used samples only from Tochigi. Introductions into different habitats can alter species characteristics, including perhaps cuticular hydrocarbons. To validate our method for frass samples from different habitats, we analyzed and compared hydrocarbon profiles in frass between the beetle’s native habitat (Korea) and two more Japanese habitats (Aichi and Saitama).

To express the nematode transmission capacity, we proposed the probability (q) of a nematode being transmitted to trees by a beetle individual and the nematode transmission probability (Q) by a beetle population. The q value was calculated as nt/ni, where ni was the initial number of nematodes that a beetle carried and nt was the number of nematodes transmitted by it.
