Aliaporcellana pygmaea   (de Man, 1902)

( Fig. 1 View FIGURE 1 )

Porcellana pygmaea   de Man, 1902: 698, pl. 23, figs. 38, 38a –e (type locality: Ternate, Indonesia). Polyonyx pugilator Nobili, 1905: 161   (type locality: Persian Gulf).

Polyonyx pygmaeus   .— Lewinsohn, 1969: 161, fig. 36.

Aliaporcellana pygmaea   .— Nakasone & Miyake, 1969: 19.

Material examined. Loyalty Islands. Lifou Island. Santal Bay. Atelier LIFOU. St. 1459 (St. 6), Ngoni, 20 °47.0’S, 167 °03.0’E, 55–80 m, dredge, 13 Nov. 2000: 1 male CL 2.2 mm. St. 1446 (St. 41 B), Mepinyo, 20 ° 50.8 ’S, 167 °09.7’E, 36–40 m, 16 Nov. 2000: 1 male CL 4.8 mm. St. 1457 (St. 67), Ngoni, 20 ° 46.8 ’S, 167 °02.75’E, 5–10 m, 27 Nov. 2000: 1 male CL 4.6 mm.

Remarks. Lewinsohn (1969) discussed the variations that occur in this species according to sex and increase in size of individuals.

Aliaporcellana pygmaea   is distinguished from A. suluensis   primary by the produced lateral lobes of the rostrum usually visible in dorsal view ( Fig. 1 View FIGURE 1 A); smaller cheliped with scattered, stout, stiff setae and with the carpus and dactylus armed with slender, acute teeth on the dorsoflexor (posterior) margin ( Fig. 1 View FIGURE 1 B, C); and dactyli of the ambulatory legs each with a single corneous spine on the flexor margin ( Fig. 1 View FIGURE 1 D; unarmed in A.

suluensis   ). These characters agree well with the original description and illustrations of Porcellana pygmaea   by de Man (1902).

Aliaporcellana kikuchii Nakasone & Miyake, 1969   closely resembles A. pygmaea   , but differs in having the lateral lobes of the rostrum each terminating in a small spine and dactyli of the ambulatory legs unarmed on the flexor margin (a short, corneous spine is present in A. pygmaea   ).

Distribution. Red Sea, Gulf of Aden, Persian Gulf, Seychelles, Madagascar, Cargados Carajos (northeast of Mauritius), Gulf of Thailand, Java Sea, Moluccas, New Caledonia, and Loyalty Islands. Shallow water to 62 m; among sponges and antipatharians ( Haig 1983, 1989). The specimens examined were collected at depths of 5–80 m in the Loyalty Islands.
