Hubbardia pentapeltis
short-tailed whipscorpion
Hubbardia pentapeltis is a species of short-tailed whipscorpion in the family Hubbardiidae, first described by Cook in 1899. It belongs to the order Schizomida, a small group of arachnids characterized by their compact bodies and reduced flagellum. The species is known from North America and has been documented in citizen science observations.
Stenochrus
short-tailed whipscorpions
Stenochrus is a genus of hubbardiid short-tailed whipscorpions (order Schizomida) first described by Ralph Vary Chamberlin in 1922. The genus was historically considered a 'junkyard' taxon containing morphologically disparate species, but integrative systematics using molecular and morphological data has redefined its boundaries. As currently circumscribed, Stenochrus comprises approximately ten species distributed primarily in Mexico, Central America, and the Caribbean. The most widespread species, Stenochrus portoricensis, exhibits exceptional geographic range due to parthenogenetic reproduction and ecological tolerance, with introduced populations established in South America and Europe.
Thelyphonidae
whipscorpions, vinegaroons, whip-scorpions
Thelyphonidae is the sole family of the arachnid order Uropygi (Thelyphonida), containing approximately 140 described species in 25 genera (16 extant, 9 fossil). Members are commonly known as whipscorpions or vinegaroons due to their whip-like flagellum and defensive secretion of acetic acid. The family is divided into four subfamilies: Hypoctoninae, Mastigoproctinae, Thelyphoninae, and Typopeltinae. Despite their conspicuous appearance and wide tropical distribution, systematic knowledge of the group has advanced slowly.
