Bruce, Niel L. & Sidabalok, Conni, 2011, The genus Lanocira Hansen, 1890 (Corallanidae: Isopoda: Crustacea) in tropical Australian waters, Zootaxa 2793, pp. 23-34 : 26

Lanocira sp. ( cf. anasicula Jones, 1982 )

( Fig. 2 A–D)

Material examined. 1 3 (6.1 mm), Hibernia Reef, WA (Timor Sea), 11º58.116’S, 123º22.133’E, 12 May 1992, 6 m, patch reef, symbiotic with Acropora , coll. J.W. Short (MTQ W17820).

Holotype of Lanocira anasicula Jones, 1982 (3, 6.9 mm; TNH 1979.217.1) and paratypes (2 3, 6.5, 4.6 mm; TNH 1979.218.2)—Watamu, Kenya, 18 August 1969, coll. D.A. Jones. All specimens previously destructively dissected and dissected appendages not deposited with the specimens.

Remarks. The single specimen bears a remarkable similarity to Lanocira anasicula Jones, 1982 ( Fig. 2 E–H), notably in having a clearly quadrate anterior margin to the rostrum. The specimen from Hibernia Reef differs in a number of characters: the body is broader (2.1 as long as greatest width, vs 2.6 for L. anasicula ), the uropods extend well beyond the pleotelson apex (only sightly beyond), the dorsum of the pleotelson has numerous stiff setae (without setae in mature males of L. anasicula , but present in the immature male paratype which also has setae on the pleonites), and the cephalic ridges above the eye are distally acute ( Fig. 2 C) (distally truncate in L. anasicula , Fig. 2 E).
