Eupoa
Encyclopedia
Eupoa is a genus
of the spider
family Salticidae (jumping spider
s). Originally known only from one species from Vietnam
, several other species have been described since 1997, all from China.
Spiders of this genus have unusual pedipalp
s, and do probably not belong to the Salticoida
, the main clade of jumping spiders. It is basal
, but placement is not yet clear. Possibly Eupoa has branched from other basal groups like Lyssomaninae
or Spartaeinae
a long time ago.
Specimens of E. prima were collected from leaf litter.
The abdomen is dark with light elongate transversal patches.

Pedipalp
Pedipalps , are the second pair of appendages of the prosoma in the subphylum Chelicerata. They are traditionally thought to be homologous with mandibles in Crustacea and insects, although more recent studies Pedipalps (commonly shortened to palps or palpi), are the second pair of appendages of the...

In phylogenetics, a basal clade is the earliest clade to branch in a larger clade; it appears at the base of a cladogram.A basal group forms an outgroup to the rest of the clade, such as in the following example:...
