Type material.

Holotype female (QM S61052): Upper Lankelly Creek [13°57'S, 143°12'E], Coen District, Queensland, Australia, 10-11.VI.1971, G.B. Monteith.

Etymology.

This species is named for the collector, G.B. Monteith, in honor of his amazing collecting prowess.

Diagnosis.

Females of Karaops monteithi sp. n. can be distinguished from other species by having highly coiled ducts, very small spermathecae located medially, and a small posterodorsal fold (Fig. 16). Males unknown.
