Holotype: AM P.85990, female, tl. = 5.4 mm (with 3 microslides), Australia, Queensland, Heron Island , bommie west of harbour entrance, 23°26'S 151°55'E, 21 m, J. K. Lowry, 7 Dec 1978. GoogleMaps

Description of holotype. Head. Head 1.7 times as long as deep; rostrum minute; anteroventral margin oblique-horizontal; eyes present, with 2 pairs with cuticular lenses. Antenna 1 peduncular article 2 as long as article 1; flagellum of 2 articles; reaching to midlength of antenna 2 article 3. Antenna 2 about half body length; peduncular article 5 about half as long as article 4.

Pereon. Coxae 1–3 rounded, slightly scalloped on coxa 1. Pereopods 3, 4 dactylus longer than propodus. Pereopod 5 basis flexor margin sinuous; extensor margin with 7 plumose setae. Pereopod 6 basis subcircular, extensor margin with 4 plumose setae. Pereopod 7 basis posterodistal margin truncate-rounded, reaching to midlength of carpus, free anterior margin setose near junction with ischium; merus wider than long; carpus 1.3 times as long as wide, as long as ischium-merus together; propodus subrectangular, 1.5 times as long as wide.

Pleon. Epimeron 3 posteroventral margin broadly rounded. Uropod 1 outer ramus with 2 short robust setae. Uropod 2 inner ramus inner ramus shorter than outer ramus, upper margin with 2 robust setae. Uropod 3 rami inner margins of both rami microscopically serrate. Telson 1.7 times as long as wide, strongly tapering, cleft about one-third of length, with pair of long dorsal robust setae; distal margin bilobed, distal margin minutely serrulate.

Distribution. Australia, Qld, southern Great Barrier Reef, 21 m (known only from type locality).

Remarks. Byblis wadara sp. nov. is notable for the exceptionally short antenna 1, its flagellum of only two articles. It would appear to be the only species like this.
