About

Dynastes hercules takakuwai lives in Rondonia, northern Brazil, with Pimenta Bueno as type locality. Males measure 70-142 mm in total length and females 50-65 mm. Its horn processes are the weakest of all subspecies: the cephalic horn is slender and evenly curved, the subapical process nearly absent or rod-like, and basal processes absent or vestigial; the thoracic horn is evenly curved with a tiny or absent process. Elytra are brownish ochre with rather large black spots and the hair is reddish brown. The female was still unknown as of 2006. The name honours Dr Masatoshi Takakuwa of the Kanagawa Prefectural Museum. The type locality is being developed, so future collecting is expected to be difficult. Keep at 20-26 C and let females lay in fermented substrate; adults live 8-12 months and larvae take 1-1.5 years (females) or 1.5-2 years (males). The BE-KUWA captive record is 142.1 mm (2011).

Dynastes hercules takakuwai — Rondonia, northern Brazil

Subspecies of Rondonia. The GBIF backbone lists it as a synonym of ecuatorianus, while BE-KUWA keeps a separate record category. Subspecies status is debated: Ratcliffe (2003) proposed synonymising all subspecies, but BE-KUWA and Ratcliffe's own 2013/2015 works keep the traditional subspecies (ja Wikipedia).
