日本初記録の害虫種タイリクマツカレハ（チョウ目：カレハガ科）（新称）を含む日本産Dendrolimus属4種の識別法

The masson pine moth, Dendrolimus punctatus（Walker）（Lepidoptera: Lasiocampidae）, is a notorious pest of pine trees in Asian countries and was recorded in Japan for the first time from Ishigakijima Island and Iriomotejima Island. We performed taxonomic studies involving the male and female genitalia and clarified the distinguishable features among the following four Japanese species of the genus Dendrolimus: D. superans（Butler）, D. spectabilis（Butler）, D. okinawanus Sonan, and D. punctatus based on many specimens including the lectotype of D. punctatus. As for DNA barcoding, five of the analyzed Japanese haplotypes from Ishigakijima Island and Iriomotejima Island and three of the Chinese haplotypes registered in GenBank as D. punctatus belonged to the same clade in the NJ tree. The intraspecific divergence value within D. punctatus was higher than the interspecific divergence value between D. okinawanus and D. spectabilis. In addition, we revealed that D. punctatus induced severe damage in Pinus luchuensis Mayr on Ishigakijima Island in 2016.
