DANALIA SP.

( FIGS 7C, D, 11E)

Material examined

Indonesia: Immature female (4.3 mm) (RMNH. Crus.I.7756), on abdomen of female F.syzygia van der Meij, 2015 (3.2 mm long × 2.7 mm wide) (RMNH.Crus.D.54220), ex Cycloseris sinensis H. Milne Edwards & Haime, 1851 ( Fungiidae ), Teluk Makawide, Lembeh Strait, 01°29′05″N, 125°14′26″E, 9 February 2012, coll. S. E. T. van der Meij.

Remarks

This unique specimen most resembles some specimens of D. curvata ( Fraisse, 1878) in overall shape, but the position of the trunk (offset from the ventral median) differs from that of D. curvata (terminal on anterior end). However, D. curvata is a Mediterranean species that has been recorded parasitizing the rhizocephalan Drepanorchis neglecta ( Fraisse, 1878) found on the spi- der crab Inachus communissimus Rizza, 1839 , rather than being a direct crab parasite. Given that only a single immature specimen exists, and the shape could be altered with development (i.e. as occurs with D. curvata ), it is not advisable to describe the specimen at this time, despite the characters that suggest it represents a new species.
