Grymeus have setaceous book-lung covers, stout, blunt, carinate setae, and a distal patch of curved setae on the male pedipalp cymbium; males with pouch and without porrect cheliceral setae.
Goblin Spiders
Oonopidae
(after Framenau. et al. 2014): The name Goblin Spiders for the family Oonopidae refers to the somewhat peculiar appearance of these small spiders. They are often hard-bodied with strong sclerotised abdominal plates (scutes) and orange-brown in colour. At a global scale, Goblin spiders are known for some unusual morphological features, such as bizarre spines on the head, horny extensions on the chelicerae, strange-looking mouthparts, sternal pouches, and hand-like extensions on the posterior coxae to name just a few.
Goblin Spiders are very similar to the Six-eyed Ground Spiders (Orsolobidae) and some Australian genera were initially placed in the oonopids until the family Orsolobidae was established. Differences between both families are subtle and include a peculiar, raised morphology of a tarsal chemosensory organ in orsolobids.
Grymeus
2 species
Opopaea females and males have a pair of small dorsolateral, triangular extensions on the pedicel as well as paired curved scutal ridges on the scuto-pedicel region.
Opopaea
5 species
Orchestina have enlarged femur IV; many species have a dark reticulated pattern on the carapace and dark patterns dorsally on the abdomen.
Orchestina
1 species
Pelicinus males are characterised by a fairly enlarged and rounded bulbus of the pedipalp, a relatively short embolus with small, slender accessory sclerites and a conspicuous hump near the basal portion of the embolus.
Pelicinus
4 species
Males easily distinguished from Opopaea by the separate cymbium and bulb, which is fused in a few species; females and males lack a pair of small dorsolateral, triangular extensions on the pedicel as well as the paired curved scutal ridges on the scutopedicel region.
Prethopalpus
1 species
Similar to Gamasomorpha, from which they differ by the modified anterodorsal edge of the booklung covers, which bears a remarkable pointed tubercle.
Xestaspis
4 species
