Type material. Female holotype and 1 male paratype ( ANIC # 42–000001 ), Australian border interception (N129746) from oranges imported from USA, 21 March 2010, coll. C. Hill; female paratype, Australian border interception (N129965) from oranges imported from USA, 8 April 2010, coll. V. Cheok .

Etymology. This species name is derived from the Latin word speciosus (beautiful) and treated here as a noun in apposition.

Remarks. This species differs from the second species of this genus, O. chimaera ( Bochkov and Ochoa, 2005) comb. nov. described originally in the genus Alliea and still known only from females by the presence of two filiform setae on tibia II, the distinct ornamentation of the dorsal shields, and by the absence of angles on leg tarsal claws. In O. chimaera , only one seta on tibia II is filiform, ornamentation of dorsal shields is indistinct, the tarsal claws are with angles.
