TYPE MATERIAL: Female holotype and male allotype from NE Queensland, 3 km W. Bones Knob 17° 13′ S, 145° 25′ E, 1100 m. 10 December 1995, Monteith, Cook & Thompson, between trees and logs of Pyrethrum sp. ( QM)

DIAGNOSIS AND DESCRIPTION: See genus diagnosis and description. Female description based on specimens (TEAU015, TEAU020 to 22, TEAU041). Male description based on specimens (TEAU014, TEAU041).

VARIATION: Males (N = 5) total length 3.44– 4.20. Cephalothorax length 1.82–2.09, width 1.39–1.58. Femur length 2.88–3.31. Females (N = 5) total length 3.54–3.84. Cephalothorax length 1.49–1. 67, width 1.17–1.35. Femur length 2.43– 2.85. The epigynum triangular plate base varies from straight to slightly curved.

ETYMOLOGY: The species epithet refers to the characteristic spermathecae of this species, which are conspicuously divided several globular clusters (from the Greek word theca a chest, box, or other container).

DISTRIBUTION: This species is endemic to Queensland (fig. 60B).

NATURAL HISTORY: Iamarra multitheca is found exclusively in the tropical region of northern Queensland. These spiders build dense, horizontal webs, which may or may not have open hubs, at the base of tree trunks (fig. 6).

REMARKS: This species was misidentified in Wheeler et al. (2017) as “ Dolichognatha sp. GH59.”
