Earth Mouse Spider Missulena terra Marsh, Stevens & Framenau, 2023

(after Marsh et al. 2014): Males of M. terra are most similar to seven other species which share a brown carapace and chelicerae: M. durokoppin, M. faulderi, M. harewoodi, M. leniae, M. melissae, M. pinguipes, and M. rutraspina. Of these, they differ from M. durokoppin, M. faulderi, M. leniae, and M. rutraspina by having a rounded rectangular shaped and swollen pedipalp tibia, 1.7 the length times the width, which is distinctly more slender in these other species. They differ from M. pinguipes by having a smooth carapace, which is granulated in M. pinguipes and by the shape of metatarsus IV, which is inflated in M. pinguipes, but not so in M. terra. Males of M. terra differ from M. harewoodi by the lack of retrolateral and dorsal transverse striations on the chelicerae in M. harewoodi. They are further separated by M. harewoodi by the rounded rectangular shape of the pedipalp tibia in M. terra, which is broadly teardrop shaped and narrowed apically in M. harewoodi, and by the shape of the embolus, which has a distinct basal embolar intumesence in M. terra, thickened until around half the embolus length, but is narrower basally in M. harewoodi.
