Moguai elongatum ( Rathbun, 1931) View in CoL

( Fig. 1 View FIGURE 1 b)

Camptandrium elongatum View in CoL — Rathbun 1931: 95, pl. 13, figs. 40–43; Shen 1935: 33, fig. 10A–C; 1940a: 73, 93; 1940b: 234; Shen & Dai 1964: 115; Manning & Holthuis 1981: 199; Dai et al.

1986: 439, fig. 246; Dai & Yang 1991: 482, pl. 61 (3), fig. 246(1). Moguai elongatum — Tan & Ng 1999: 205, figs. 3C, D, G, 4D, E.

Material examined. 1 male, CL 2.8 mm, 2 females, CL 2.3, 3.2 mm, RUMFZC32, Motonagura, Ishigaki I., coll. T. Naruse & T. Nagai, 21 Dec. 2004; 1 female, CL 5.1 mm, RUMFZC33, Motonagura, Ishigaki I., coll. T. Naruse & T. Nagai, 20 Mar. 2005.

Remarks. The specimens from Ishigaki Island agree well with the description of M. elongatum by Rathbun (1931) and Tan & Ng (1999). The range of this species is extended east from Fukien Province, China.

Shokita (1990) had recorded M. elongatum from Iriomote I., which is located less than 20 km west of Ishigaki I., but he did not provide a description or figure. Shokitaís (1990) material is almost certainly lost (S. Shokita, pers. comm.), and as such, the identity of his specimens cannot be determined.

Specimens from Ishigaki I. were collected from riverbeds of river mouths, with a pebblysandy substratum. The locality is exposed by seawater at high tide.
