Phylladiorhynchus bengalensis Tirmizi & Javed, 1980

Phylladiorhynchus bengalensis Tirmizi & Javed, 1980 a: 258 , fig. 2 (Andaman Sea, 77 m).— Tirmizi & Javed, 1993: 31, fig. 14 (redescription).— Baba, 2005: 304 (key, synonymies).— Baba et al., 2008: 175 (compilation).— Schnabel & Ahyong, 2019: 304 (key).

Diagnosis. Rostrum triangular, subapical spines absent or, if present, obsolescent, lateral margins straight. Carapace with epigastric ridge armed with 5 spines; anterior branchial margin with 3 spines; anterior protogastric ridge not interrupted medially, without scale behind median epigastric spine; anterior mesogastric and metagastric ridges not medially interrupted. Anterior margin of thoracic sternite 3 nearly transverse with median and lateral projections. Antennule article 1 with 5 distal spines; distomesial spine minute. Antennal article 2 with distolateral spine longer than distomesial; article 3 with minute distomesial spine. Flexor margin of Mxp3 merus with 2 prominent spines. P2–4 dactylus extensor margin without upright spines at bases of movable spines.

Distribution. Only known from the type locality, Andaman Sea, at 77 m.

Remarks. The species is only known by the holotype male and it is characterized by the presence of 5 epigastric spines, 1 small hepatic spine, and 3 spines on the anterior branchial margin. The closest relative is P. ikedai ( Miyake & Baba, 1965) from Bonin Islands, Japan. However, they can be easily differentiated by the shape of thoracic sternite 3, with the anterior margin nearly transverse, and median and lateral projections, in P. bengalensis , whereas the sternite has the anterior margin convex, with feeble median excavation in P. ikedai .
