Today's subject is Centruroides limbatus (Pocock, 1898). The
generic name Centruroides is from the Greek words centr-,
meaning "pointed," and ur, meaning "tail." The
genus was originally called Centrurus, but had to be changed to Centruroides because
the name Centrurus was already in use for another animal. The "-oides " ending
means "like" or "the form of," so the name really means "like Centrurus." The
specific name, limbatus, is from the Latin meaning "black-edged" and
refers to the coloration of the scorpion.
This scorpion is in the family Buthidae. Centruroides can
be divided into several species groups. Centruroides limbatus belongs
to the Gracilis species group. All of the species in this group are characterized
by fairly large size (> 100 mm) and long, narrow pedipalps.
Pocock, R. I. 1898. Description of some new scorpions from Central
and South America. Annals and Magazine of Natural History, series
Centruroides limbatus is found throughout Costa Rica, and in
parts of Nicaragua and Honduras. This scorpion is quite common in Costa
Rica. It is apparently less common in other parts of its range.
Like all Centruroides, this species lives in any type of crevice,
normally near the ground. They frequent human dwellings where food and
shelter are abundant. Food is any small arthropod. Though large in size,
this species is not considered dangerous to humans. Nonetheless, they are
venomous and being stung by one is no picnic.
