Marin, Ivan & Anker, Arthur, 2011, A partial revision of the Philarius gerlachei (Nobili, 1905) species complex (Crustacea, Decapoda, Palaemonidae), with description of four new species, Zootaxa 2781, pp. 1-28 : 26

Philarius sp.

( Fig. 20 )

Material examined. 1 ovigerous female, pcl 2.3 mm ( FLMNH UF Arthropoda 24709), Australia, Great Barrier Reef, Heron Island, First Point, sta. 6, 23.43322 S, 151.93375 E, depth: 1–2 m, rubble and corals with sandy patches, in rubble, coll. CReefs team, 12.XI.2009 (fcn AUST 4684).

Colour pattern. Semitransparent with greenish tinge; antennular and antennal flagella bluish; colour pattern generally similar to that of P. m i n o r n. sp. (cf. Fig. 19 C, D).

Remarks. Unfortunately, this specimen is too incomplete to be positively identified, missing both P2 and most P3–5. It is generally similar to P. polynesicus n. sp. and P. m i n o r n. sp., differing from the former by the colour of the antennular and antennal flagella and the fewer segments in the fused portion of the lateral antennular flagellum, and from the latter by the absence of supraocular lobes on the proximolateral rostral lamina and the somewhat stronger dorsal rostral teeth ( Fig. 20 A). We hope that ongoing DNA analyses of the FLMNH decapod collections will soon elucidate the identity of this specimen.
