| Pedipalp
Tarsus-Final segment of the pedipalp
In mature male spiders, the final
segment of the pedipalp, the tarsus, develops into a complicated
structure (the palpal organ or bulb) that is used to transfer sperm
to the female seminal receptacles during mating. The details of this
structure vary considerably between different groups of spiders and
are useful for identifying species.
Pedipalps are sensitive chemical detectors and function as taste and
smell organs, supplementing those on the legs.
The cymbium is a spoon-shaped
structure located at the end of the spider pedipalp that supports
the palpal organ. |
