Diagnosis

According to Lin and Zhang (1993), Brachymna tenuis resembles B. castanea . It differs from the latter by the yellowish-brown body colour (Fig. 1 a, b) (ferruginous in B. castanea ) and the pygophore bearing dentate postero-lateral processes that are obtusely curved from the postero-ventral margin (Fig. 1 c) (postero-lateral processes make approximately a right angle with the postero-ventral margin in B. castanea ).

Distribution

China, Japan, Taiwan and South Korea (new record).
