Naushonia carinata Dworschak, Marin & Anker, 2006

Naushonia carinata Dworschak et al. 2006: 3 View Cited Treatment   , figs. 1–6 (type locality: Dâm Bay of Tré Island, Nha Trang, Vietnam).— Anker et al. 2015: 333 View Cited Treatment , fig. 24 A (Lombok, Indonesia).

Material examined. Japan: 1 ovigerous female (pocl 7.1 mm), Yaeyama Islands, Iriomote Island, Shirahama, intertidal, soft sediment with sea grass, suction pump, coll. T. Komai, 14 May 2014, RUMF-ZC 3677. Description. See Dworschak et al. (2006).

Colouration in life. Body and appendages whitish; yellowish-brown hepatopancreas and pale orange ovary visible through integument ( Fig. 1 A View FIGURE 1. A ).

Distribution. Western Pacific: Vietnam (Nha Trang Bay), Philippines (Panglao), Indonesia (Lombok) ( Dworschak et al. 2006; Anker et al. 2015); Japan (Ryukyu Islands) (present study).

Habitat. Intertidal and shallow subtidal, presumably in burrows of the callianassid ghost shrimp Glypturus armatus ( A. Milne-Edwards, 1870) ( Dworschak et al. 2006)   .

Remarks. Naushonia carinata   was originally described on the basis of four type specimens, viz. female holotype, male allotype and two female paratypes, from Nha Trang, Vietnam, and one additional female from Panglao, near Bohol, in the Philippines ( Dworschak et al. 2006). More recently, Anker et al. (2015) recorded this species also from Lombok, Indonesia.

The present specimen agrees well with the description provided by Dworschak et al. (2006), except for the gill formula. According to Dworschak et al. (2006: Table 1, figure 4 f), in the type specimens of N. carinata   , the first maxilliped is devoid of an arthrobranch at its base. In contrast, our specimen from Iriomote Island has a single, well-developed, multi-lamellate arthrobranch near the base of the first maxilliped. At our request, Dr. Peter C. Dworschak re-examined two paratypes of N. carinata   deposited in the Naturhistorisches Museum in Wien, Vienna, Austria ( NHMW), and confirmed that in these specimens there is indeed no arthrobranch at the base of the first maxilliped. Therefore, it seems most reasonable to assume that the development of this arthrobranch is a variable character in N. carinata   . For instance, Astall et al. (1997) reported a variation in the number of gills present on the first and second maxillipeds in the northeastern Atlantic laomediid Jaxea nocturna Nardo, 1847   .

Naushonia carinata   is one of the most distinctive species of the genus, recognizable by the generally stout and wide body, the presence of three sharply defined, longitudinal carinae (one median and two submedian) on the first to fifth pleomeres, and the relatively broad cheliped palm ( Fig. 1 A View FIGURE 1. A ). Dworschak et al. (2006) suggested a possible association of N. carinata   with spacious burrows of the large callianassid ghost shrimp, Glypturus armatus   . The Indonesian specimen recently reported by Anker et al. (2015) was collected from a burrow of unknown host, on a shallow sea grass flat with abundance of mounds and burrow entrance holes of G. armatus   (A. Anker, pers. obs.). Similarly, the specimen from Iriomote Island was collected from a burrow on an intertidal sand-mud flat with some sea grass, however, without a clear evidence for callianassid association.
