Examples of Using EPIGYNE in a Sentence
- The primary function of the epigyne is to receive and direct the palpal organ of the male during copulation.
- Once this happens, the male will wrap its legs around the female tightly and insert its pedipalps into the female's epigyne, transferring its spermatophores (silk packets containing sperm) into the female's spermathecae.
- The epigyne is simple, with a pair of circular "windows" (fossae) to the front and a pair of oval spermathecae to the rear.
- After presenting the nuptial gift to the female, she bites on to the gift and the male moves to her epigyne to deposit sperm with his pedipalps.
- The epigyne can vary, but the pedipalp has a median apophysis and a colulus is absent from both genders.
- As with most spiders, accurate species-level identification requires examination of the mature genitalic structures (the epigyne in females, and the palpal bulb in males).
- Male pedipalps are characterised by a cymbium that extends well beyond the bulb and species can be differentiated by the morphology of the male tibial apophyses and female epigyne.
