The identification of the spider presented on this page was based on the contents of the following paper: Bayer S. (2011) "Revision of the psuedo-orbweavers of the genus Fecenia Simon, 1887 (Araneae, Psechridae), with emphasis on their pre-epigyne" ZooKeys 153 1-56. In this paper it is indicated that the genera Fecenia and Psechrus are reasonably similar in appearance but differ in that the anterior median eyes of Fecenia are larger than the other six eyes whereas on Psechrus they are small, and also Leg IV of Fecenia is clearly shorter than Leg II but on Psechrus those two legs are about the same length or Leg IV is the longer one. The World Spider Catalog lists only two psechrid species as being present in Australia (both in Queensland), these being Fecenia ochracea and Psechrus argentatus, and the anatomical differences stated in this paragraph mean the spider in the above images can only be Fecenia ochracea or an undescribed species.

Distinguishing features of the male of this species are its long, slender legs with rasp-like teeth on some leg segments and relatively long claws. Note that these claws are somewhat similar to those on Progradungula species (Family Gradungulidae) but Fecenia actually has two claws of similar size (Progradungula has one very large claw and one smaller one) plus a very small third claw and a thin associated tuft of hairs. Progradungula also has a more nearly globular abdomen and its body lacks the patterning that is on Fecenia. Another apparent difference is that Fecenia builds a vertically suspended web with an attached rolled leaf as a retreat whereas Progradungula is mainly found in association with cave entrances. Finally, it should be pointed out that the female of Fecenia ochracea has a broader abdomen and shorter, less slender legs than the male of that species.
