Today's subject is Heteronebo yntemai Francke & Sissom, 1980. The generic name, Heteronebo, is from the Greek word hetero -, meaning "other," and Nebo, a genus of large diplocentrid scorpions from the Arabian Peninsula. The name indicates a perceived relationship between the two taxa. The specific name, yntemai, is a patronym honoring John A. Yntema, Bureau of Fish and Wildlife, St. Croix, who collected many of the specimens used by Sissom & Francke (1980) in their description of this species.

This scorpion is in the family Diplocentridae. Though similar to other American diplocentrids in overall morphology, Heteronebo shares one characteristic with the genus Nebo, an Old-World diplocentrid. Namely, the lack of a distinct transverse keel on the underside of the metasomal segment V.

Heteronebo yntemai is found in the U.S. and British Virgin Islands. It has been reported from St. John Island and Mingo Cay in the U.S. Virgin Islands, and Peter, Jost Van Dyke, Virgin Gorda, Mosquito islands in the British Virgin Islands. Next to nothing is known of the habits of this tiny scorpion (adult size is about 25 mm [1 inch]). I have found it under stones and in limestone rubble on St. John Island. This scorpion is quite common. Like all scorpions, this species is venomous, but not of any danger to humans.
There are about 15 described species and subspecies of Heteronebo. Most species are found only on the islands of the Caribbean. However, two species are known only from the tiny island of Abd-el-Kuri, Peoples Democratic Republic of Yemen, at the mouth of the Gulf of Aden. Go figure.
