About
Prosopocoilus umhangi was described by Fairmaire in 1891. Of the 143 specimen records aggregated in GBIF, 78 come from Tanzania and 11 from Malawi, with further records from the Central African Republic and Namibia, so the range centres on East Africa. The BE-KUWA 2025 edition gives a captive record of 72.0mm (Sasaki Kaoru, registered 2024), a wild record of the same 72.0mm and a predicted maximum of 76mm. A female captive record of 38.4mm (Amano Tsuyoshi, registered 2017) and a smallest male captive record of 28.7mm (Inoue Kyota, registered 2022) are also listed. African Prosopocoilus are not widely traded in Japan and little is known of their life in the wild. Care follows the standard routine for foreign saw stags: hold adults and larvae near 20-24C and breed on a log buried in fermented substrate.
