Dynastes hercules tuxtlaensis
The smallest and northernmost subspecies, from Los Tuxtlas in Veracruz, Mexico. No specimens beyond the two type males are known, and some researchers treat it as septentrionalis.
Dynastes hercules tuxtlaensis is described from Los Tuxtlas (Santa Marta massif) in Veracruz, southern Mexico, the northernmost of all subspecies. Males are small at 62-80 mm total length; the female is unknown. The cephalic horn is short and curved near the middle; the thoracic horn base is clearly curved with a fairly large process near the base and relatively coarse punctures. Elytra are dirty yellow with small black spots and the hair is reddish brown. As of 2006 no specimen other than the two type males had been recognised, and some researchers treat it as septentrionalis; GBIF also lists it as a synonym of septentrionalis. Specimens are extremely scarce, and the Nara Ookuwa Center is known to have bought three specimens for a large sum. Live trade and captive rearing are practically non-existent; if kept, treat it like other subspecies at 20-26 C with fermented substrate for egg laying. Species-level guides give adults 8-12 months and larvae 1-1.5 years (females) or 1.5-2 years (males).

Notable localities
Regional subspecies
Northernmost and smallest subspecies, known only from the two type males; the GBIF backbone and some researchers treat it as a synonym of septentrionalis. The BE-KUWA 2025 list has no record category for it. 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).

Plant Protection Act: When importing live specimens of Scarabaeoidea (including rhinoceros beetles, stag beetles, flower beetles, etc.), a species identification certificate issued by the exporting country government agency or equivalent must be attached in accordance with the Invasive Species Act (import ports are limited to Narita, Chubu, Kansai, Fukuoka, and Kagoshima airports). This species itself is not a designated invasive species, and import is possible upon submission of the certificate.

Keep at roughly 20-26 C and avoid Japanese summer heat. The northernmost and smallest subspecies, with virtually no captive records.
Females lay in fermented substrate packed 20 cm or deeper. Rear larvae singly in roughly 10 L containers; the larval period is long, 1-1.5 years for females and 1.5-2 years for males, and shortens at higher temperatures.
Basically mild-tempered, but fights over food, so keep singly. Very rarely a male crushes and kills a female, so never leave a pair unattended.
Adults live about 8-12 months. Egg to emergence takes 1.5-2.5 years, so patience is needed.
The thoracic and cephalic horns pinch very hard, so keep fingers clear. A cramped enclosure stresses males and shortens their life. Long-horned males tip over easily, so add footholds.
Advanced. This is an advanced-level species. It requires specialized equipment and advanced husbandry skills with precise environmental control.
The ideal temperature for Hercules Tuxtlaensis is 20〜26℃. Avoid sudden temperature changes and maintain a stable environment.
The average lifespan of Hercules Tuxtlaensis is Adults 8-12 months. With proper care and nutrition, they can live a long and healthy life.
Hercules Tuxtlaensis typically reaches Males 62-80 mm (female unknown) as an adult. Size may vary depending on care conditions and individual genetics.
Hercules Tuxtlaensis feeds on: Beetle jelly, banana. Aim for a balanced diet with appropriate feeding frequency.
The price of Hercules Tuxtlaensis varies significantly depending on bloodline, size, captive-bred generation, and sex. Check our market price page for the latest pricing information.
