琉球小鍬形蟲

來源: Dorcus amamianus - Wikipedia (JA; ranges and sizes of the four subspecies, morphology, life cycle, lifespan, larval period) / GBIF species page for Dorcus amamianus nomurai Mizunuma, 1994, the subspecies of northern Okinawa Island / BE-KUWA Certified Breeding Records (Mushi-sha, FY2025 edition PDF, JA)

記錄來源: BE-KUWA 2025 edition, captive records for medium and large Japanese stag beetles (Ryukyu lesser stag: captive 39.2 mm, Minoru Kanazawa, registered 2007; dream maximum 44 mm; wild 36.3 mm, Naoto Yoshida). The same edition's small-specimen table lists a captive 19.0 mm (2021) and a wild 21.7 mm (Tsuneyoshi Kizaki, 2009).

The Japanese Wikipedia also gives 39.2 mm (2007) as the captive maximum for this subspecies, matching the BE-KUWA record.

國內法規: The subspecies is confined to the north of Okinawa Island, an area that includes Yambaru National Park (the villages of Kunigami, Ogimi and Higashi) and part of the World Natural Heritage site 'Amami-Oshima Island, Tokunoshima Island, Northern part of Okinawa Island, and Iriomote Island'. Inside a national park's special zones the Natural Parks Act requires permission to take animals or plants, and local authorities at collecting sites may restrict collecting by ordinance. The beetle is not designated as a National Endangered Species under the Act on Conservation of Endangered Species; among the Lucanidae only Neolucanus insulicola donan, Neolucanus okinawanus and Neolucanus protogenetivus hamaii are listed. What circulates is chiefly captive-bred stock, and anyone handling wild-caught beetles must check the rules for the collecting site.
