Abstract: | Amphitetranychus quercivorus (Ehara and Gotoh, 1990) was first identified in Mongolian oak tree Quercus mongolica in Daegu, Korea. In comparison to A. viennensis (Zacher), A. quercivorus was much shorter in the distal, dorsally directed portion of the male aedeagus, as well as smaller and less folded in the distal anastomosed portion of the female peritreme. Comparison of the nucleotide sequences of ITS2 and COI revealed 90% and 89% similarities, respectively, between the two species. In addition, species-specific primer sets for each species were designed using unique ITS2 sequences and then used to diagnose these two species under plant quarantine. We report the Korean name of this species as “Sin-gal-na-mu-eung-ae”. |
