Description
Macrophthalmus (Macrophthalmus) convexus Stimpson, 1858
(Figs. 3A, B)
Macrophthalmus convexus Stimpson, 1858: 97. — Tesch 1915: 175.
Macrophthalmus (Macrophthalmus) convexus — Barnes 1967: 211, pl. 1c, fig. 3; 1971: 9; 2010: 40, fig. 2c. — Poupin 1997: 163, figs. 1C, D, 3C–E, 4–6.
Material examined. 2 males (5.81 x 9.81, 8.00 x 13.45 mm), 1 female (5.45 x 9.09 mm) (MZB Cru 3268), 2 females (5.82 x 9.45, 6.18 x 9.81 mm) (RCLA-C.B.0255), 2 males (6.18 x 10.91, 8.00 x 12.91 mm), 1 ovig. (9.45 x 14.91 mm) (ZRC 2011.0999), Ekas, Lombok, 22.07.2009; 3 males (10.24 x 21.50; 7.60 x 14.50; 8.90 x 16.71) mm (RCLA-C.B.0256), Kayangan, Lombok, 10.10.2010.
Remarks. Komai et al. (1995) and Poupin (1997) discussed in detail the similarity of this species with M. parvimanus. The specimens in this collection agree well with the Indo-Malaysia form (Poupin 1997) i.e. the apical chitinous process of the G1 tapers to a small, acute distal tooth. The species is characterized by the broad carapace (1.9 as broad as long) with oblique upper orbital margin, elongated male chelipeds with large differentiated tooth on the cutting margin of the fingers, and the granular dorsal and ventral margins of the palm, and with a longitudinal granular ridge along the outer surface above the ventral margin of the palm chelipeds.
Habitat. Muddy substrate of lower intertidal zone of protected bays.
Geographical distribution. Thailand, Philippines, eastern Australia and Solomon Islands, northward to Taiwan, and Hong Kong (Komai et al. 1995). In Indonesia it was recorded from Maluku and Lesser Sunda Is (Poupin 1997) and Pulau Kaledupa, Sulawesi (Barnes 2010), and now Lombok.
