Diagnosis. Antennular peduncle reaching midpoint of antennal peduncle article 5. Maxilliped 3 ischium about twice as long as wide; merus with lobed mesiodistal corner, about 1.2 times as wide as long, with tooth on convex distal margin. Chelipeds meri upper margins each unarmed. Major cheliped merus lower margin with spine at midpoint; carpus 1.0–1.2 times as long as wide; palm 1.4–1.7 times as long as carpus, 1.3–1.4 times as long as wide; fingers, cutting edges with obsolete teeth. Uropod endopod 1.5–1.7 times as long as wide; anterior margin convex, with two distal stout setae; distal-posterior margin not differentiated from anterior margin, more convex distally; dorsal face with row of three (rarely four) spiniform setae proximally and close to anterior margin. Uropod exopod rectangular, truncate distally, 1.6–1.9 times as long as wide; anterior margin straight, setose. Telson 1.2–1.3 times as long as wide, widest at strong lateral lobes at about one quarter length; posterior margin convex, with median spine; with two pairs of spiniform setae on posterolateral margins. Male pleopod 1 2-articled or filiform; pleopod 2 biramous or minuscule.

Distribution. Tropical Southwestern Pacific, Western and Eastern Coral Triangle, Sahul Shelf, Northwest Australian Shelf ( New Caledonia; Indonesia [type locality: North Sulawesi, Kwandang Bay, 75 m]; Papua New Guinea; Australia, northwestern WA); 75– 300 m.

Remarks. Callianassa propinqua was described from Kwandang, North Sulawesi, Indonesia at 75 m (De Man, 1905) and has been subsequently reported from New Caledonia ( Ngoc-Ho, 1991) and the North West Shelf of Australia ( Ngoc-Ho, 1994), where it seems relatively common. Some of the ratios of and between articles used to diagnose the species are variable between individuals.

The male from New Caledonia differs from the Indonesian and Australian specimens in having several teeth along the lower margin of the major cheliped merus and a rounder merus of maxilliped 3. This male possesses a two-articled male pleopod 1 and a biramous pleopod 2; the only male from Australia has a filiform pleopod and minuscule bud-like pleopod 2 (fig. 36h).
