Bursaphelenchus hibisci n. sp. (Nematoda: Aphelenchoididae) isolated from Ernoporus corpulentus (Scolytinae) emerged from dead Hibiscus tiliaceus (Malvaceae) twigs from Okinawa, Japan
Summary A Bursaphelenchus sp. belonging to the B. idius-group was isolated from a bark beetle, Ernoporus corpulentus, which had emerged from dead twigs of Hibiscus tiliaceus collected in Okinawa, in the subtropical region of Japan. In addition to its group-specific characters, i.e., four lateral lines in both male and female and less developed capitulum and relatively broad blade of the male spicules, the species is characterised by a relatively slender female tail with various tip shapes. Molecularly, the species is close to B. fagi and B. tiliae based on SSU and D2-D3 LSU sequences, but can be clearly distinguished from these two species. The species is described and illustrated herein as B. hibisci n. sp.
