The spinnerets

There is no question that this spider belongs in the Subfamily Prodidominae (which in 2018 was moved into the Family Gnaphosidae after originally being in a separate family) and is a Molycria species because it perfectly matches the descriptions provided by Platnick and Baehr in their 2006 paper. However, it is possible that the spider shown above is not Molycria mcleayi because there are many described Molycria species and the South-east Queensland region where this spider was found overlaps the known ranges of at least three other Molycria species: M. stanisici, M. burwelli, and M. wrightae.

Distinguishing features of this spider are its long, slender legs that lack obvious hair or spines and its extremely long anterior lateral spinnerets which are attached about half way along the underside of the abdomen. These spinnerets are said to be particularly useful for catching ants, on which the spider feeds exclusively.
