Name
Karaops keithlongbottomi Crews & Harvey, 2011 sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Type material
Holotype male (WAM T55002): Drysdale River Station, 15°42'S, 126°23'E, Western Australia, Australia, late 1995, T. Anders.
Etymology
This species is named for the late Keith Longbottom, collector of many interesting arachnids for the Western Australian Museum.
Diagnosis
Males can be differentiated from other species by having an RTA with three processes, a crescent shaped conductor with a medial quadrangular lateral projection, and a MA that is directed distally (Fig. 19). Females unknown.
