Material examined. 1 male (CW 15.3 mm; CL 11.3 mm), 2 females (CW 11.9 mm; CL 8.4 mm; CW 12.8 mm; CL 8.6 mm), LFSc.ZRC-70, Kuda (21°37’33”N 72°18’17”E), Gujarat State, India, 12 October, 2016, coll. J. Trivedi : 1 male (CW 9.6 mm; CL 6.4 mm), 1 female (CW 5.9 mm; CL 4.3 mm), ZRC 2012.0422, Somar Goth, Pakistan, 26 January 2009, coll. F. Ghory ; 1 female (CW 8.7 mm; CL 5.9 mm) ZRC 2018.0067, Buleii, Pakistan, 4 March 1986, coll. Q. Kazmi ; 1 female (CW 14.4 mm; CL 9.8 mm) (paralectotype of Pilumnopeus salomonensis Ward, 1942), ZRC 2012.0794, Salomón Islands, Chagos Archipelago, 1936, coll. R. Viader and G. Antelme ; 2 males (CW 9.0 mm; CL 6.3 mm; CW 8.0 mm; CL 5.6 mm) ZRC 2018.1364, Persian Gulf, Iran, May 2010, coll. M. Safaei.

Remarks. The specimens examined (Figs. 5, 10A–C) in the present study compared well with the description and figures in Ghory et al. (2013). Pilumnopeus convexus is close to P. serratifrons but varies from the latter in having a CW/CL ratio of 1.4 to 1.5 and a less projecting front with a shallow central notch (Davie, 1989). The specimens were collected (Figs. 6, 11D–F) from Ekkakula mangroves located in Odisha State.

The species is so far reported from South Africa, Red Sea, Gulf of Aden, Persian Gulf, and Gulf of Oman (Naderloo, 2017). In India, the species was recorded from Gujarat (Gosavi et al., 2017) located on the west coast of India.
