Heteroctenus garridoi
(Armas, 1974)



Common names:

Carribean (Endemic from coastal desert areas in extreme southeastern Cuba).

This species lives mainly under stones and inside dead agave (Agavaceae: Agave sp.), occassionally found also under barks and inside houses.

No medical data available. From Dr. Teruel's experience: mild venom, sharp painful sting with aftereffects lasting for 1-5 hrs. This species is much more irritable and prone to sting than H. junceus, but its sting is much less

Adult size: males 45-70mm, females 65-75mm. Color: entire body pale yellowish brown to light orange, with reddish pedipalp fingers and all ventral keels of the metasoma outlined with black. As in the case of H. junceus, it produces a clearly audible stridulating sound by swiftly rubbing the pectines with the sternite III. Females give birth only one time after each mating; gestation period 25-100 days. Lifespan in captivity: 3-4 yrs from birth to natural death.

In captivity, it can be kept perfectly under desert conditions, substratum can be either fine, loose soil or sand, with planty of stones to hide under; moist once or twice a week and provide drinking water once or twice per month. If food is available, this scorpion does not display cannibalistic behavior (as opposite for H. junceus, which is always a cannibalistic species).
