Name
Karaops larryoo Crews & Harvey, 2011 sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Type material
Holotype male (WAM T93/1333): north of Larryoo, Drysdale River National Park, 14°51'S, 126°49'E, Western Australia, Australia, 12.VI.1992, M.S. Harvey, J.M. Waldock. Paratype: same data as holotype, 1♂ (WAM T93/1332).
Etymology
This species is named for the type locality, and is to be treated as a noun in apposition.
Diagnosis
Males can be differentiated by the presence of three processes on the palpal RTA and the tip of the conductor being heavily sclerotized and directed basally (Fig. 21). Females unknown.
