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).
