The Eupnoi are a suborder of
They consist of two superfamilies, the Phalangioidea with many long-legged species common to northern temperate regions, and the small group Caddoidea, which have prominent eyes and spiny pedipalps.[1]
Examples of this suborder include Hadrobunus grandis (Sclerosomatidae), Phalangium opilio and Dicranopalpus ramosus (Phalangiidae).
Distribution
Caddoidea are mostly found in temperate zones of both hemispheres; however, they are known from the
Neopilionidae show a Gondwanan distribution, with species found in South America, South Africa and Australia.
Sclerosomatidae are divided into several subfamilies, with Gagrellinae found in the
In the Phalangiidae, the Phalangiinae are most diverse in the Mediterranean, with several endemic genera in nearby coastal Africa. Although there are several Phalangiinae in the Nearctic, they are all introduced. Opilioninae are mostly palearctic, with a few species found in Southeast Asia. Oligolophinae are holarctic, with most species found in Europe. Platybuninae are also found from Europe to the Caucasus, with one find from Sumatra.[2]
Relationships
Two different views exist at the moment: in the traditional view Eupnoi and Dyspnoi form a clade, with Laniatores as a sister group; however recently it has been proposed that Eupnoi are sister to a clade formed by Dyspnoi and Laniatores.
Systematics
Although the two recognized superfamilies Caddoidea and Phalangoidea are probably monophyletic, the limits of families and subfamilies are uncertain in many cases, and are in urgent need of further study.[2]
