Material examined. 59 males (2.60 x 4.00 mm – 6.0 x 10.54 mm), 16 females (3.45 x 4.36 mm – 5.45 x 9.27 mm), 25 ovig. (4.36 x 6.91 mm – 7.09 x 11.52 mm) ( MZB Cru 3269), 45 males (3.27 x 4.00 mm – 7.27 x 12.18 mm), 13 females (3.64 x 6.00 mm – 6.54 x 10.73 mm), 20 ovig. (4.36 x 7.09 mm – 7.09 x 11.45 mm) ( ZRC 2011.1000), Ekas, East Lombok, 15.10.2007; 1 male (4.8 x 6.9 mm) (RCLA-C.B.0257), Sekotong, West Lombok, 16.05.2007; 10 males (7.09 x 11.45 mm – 9.09 x 15.45 mm), 5 females (6.18 x 10.3 mm – 8.44 x 13.42 mm), 2 ovig. (6.72 x 11.45 mm, 8.36 x 14.72 mm) (RCLA-C.B.0258), Kayangan, East Lombok, 10.10.2010.

Remarks. This species belongs to the Macrophthalmus telescopicus complex ( Takeda & Komai 1991, Barnes 2010). Although the ocular peduncles of the specimens examined here are longer (length of ocular peduncles about 1.40 times length of the upper orbital margin, or as long as carapace length) than those recorded by Serène (1973), Barnes (1976), and Takeda & Komai (1991) (length of ocular peduncles about 1.26 times length of the upper orbital margin, or 0.9 times the length of carapace), but other characters such as the short, strongly curved terminal process of the G1 and an exorbital angle that projects beyond the second and third teeth, clearly identify these specimens as belonging to M. milloti .

Habitat. This was the most common species in the collections, found from muddy substrates of mid intertidal zone in protected bays near seagrass beds.

Geographical distribution. East Africa to the Indo-Malaysian Archipelago ( Barnes 1976) and Ryukyu Is. ( Takeda & Komai 1991).
