Haplogynae

The Haplogynae are a clade of araneomorph spiders, one of the two main groups into which the araneomorphs are divided.

Unlike the Entelegynae, they lack hardened (sclerotized) female genitalia (epigynes).

Most of the species within this group have six eyes, as opposed to most other spiders. Spiders in the genus Tetrablemma (Tetrablemmidae) have only four eyes, as do some members of the family Caponiidae; caponiids may even have only two eyes. However, spiders in the family Plectreuridae hve the normal eight eyes.
