Material examined. 1 male, CL 13.8 mm, CW 14.76 mm ( ZUTC 5768 ), Dargahan , Qeshm I., Persian Gulf, 25°09′N, 56°01′E, rocky/coral, coll. N. Fahimi, 12.11.2018 ; 2 males, CL 12.80–21.65 mm, CW 16.3–27.44 mm ( ZUTC 5768 ), Shib-Deraz , Qeshm I., Persian Gulf, 26°44′N, 55°52′E, rocky-cobble, coll. R. Naderloo, 13.11.2005 .

Distribution. Indo-West Pacific: Persian Gulf, Gulf of Oman, Red Sea, Pakistan, India, China Sea, Japan, Indonesia, Singapore, Australia.

Remarks. The present specimens exhibit high similarities with the specimens identified from Pakistan and Iran (see Tirmizi & Ghani 1996: 44, figs. 16, 17; Naderloo 2017: 307, fig. 21.17). According to the shape of the carapace, the pattern of setae, and anterolateral teeth, the specimens are tentatively referred to H. trichophoroides . As discussed by Ng & Rahayu (2020) the genus Heteropilumnus is problematical, with the taxonomy of the genus needing much revision.Also, Ng & Rahayu (2020) noted that H. trichophoroides is indeed very close to H. holthuisi Ng & Tan, 1988 and according to the figures of De Man (1895: pl. 13 fig. 8b), the structure of the anterolateral margin of H. trichophoroides seems to be more entire and less serrate than what has been described for H. hirsutior (cf. Ng & Tan 1988: fig. 3; Maenosono 2019: figs. 1C, 4).
