Type locality. Takanoshima , Japan ( Ishii, 1914) .

Distribution. Japan, Hong Kong, Korea, Taiwan ( Boyko, 2004; Cericola & Williams, 2015); Singapore ( Markham, 2009); Indonesia ( Haig & Ball, 1988); China: Bohai Sea and Yellow Sea ( An et al., 2011); Philippines (herein).

Hosts. Diogenidae : Calcinus latens (herein), Ciliopagurus strigatus ( Haig & Ball, 1988) , Dardanus woodmasoni (herein), Diogenes edwardsii (De Haan, 1849) ( Boyko, 2004) , Diogenes pallescens Whitelegge, 1897 ( Markham, 2009) , Diogenes sp. (herein). Paguridae : Pagurodofleinia doederleini ( Doflein, 1902) , Pagurus angustus ( Stimpson, 1858) ( Cericola & Williams, 2015) , Pagurus constans ( Stimpson, 1858) , P. filholi (de Man, 1887) , P. japonicus ( Stimpson, 1858) , P. lanuginosus De Haan, 1849 , P. maculosus Komai & Imafuku, 1996 , P. middendorfii Brandt, 1851 ( Boyko, 2004) , P. minutus Hess, 1865 ( An et al., 2011), P. pectinatus ( Stimpson, 1858) , P. proximus Komai, 2000 , P. trigonocheirus ( Stimpson, 1858) ( Boyko, 2004) .

Size Range (Length). Females: to 18.0 mm, males: to 4.28 mm ( Boyko, 2004).

Remarks. The Indonesian specimens identified by John Markham and reported by Haig & Ball (1988) as “an undescribed species of Athelges ” (LACM CR 1975- 589.4) were examined and found to conform well to A. takanoshimensis with its characteristic female terminal abdominal segment (Fig. 3E). Markham (2010: 178) reported that the material from Indonesia of Haig & Ball (1988) was lost, based on a personal communication from E. E. Ball, but it was actually in the LACM collections. However, Markham (2010) correctly surmised that the material was probably A. takanoshimensis and not a new species. Athelges takanoshimensis is an oft-reported and relatively widely distributed bopyrid, known from 15 hermit crab hosts (see McDermott et al., 2010; Cericola & Williams 2015), but the parasite is apparently rare in the Philippines. Only a single female was found, although only a single specimen of the host, Dardanus woodmasoni , was collected. A small number of Ciliopagurus strigatus , the host of the Indonesian specimen reported herein, were collected from the Philippines, but none bore abdominal or branchial bopyrids. Ciliopagurus strigatus is known as a bopyrid host ( Haig & Ball, 1988; Markham, 2010) for A. takanoshimensis while Dardanus woodmasoni is first reported here as a host for bopyrids. One female of A. takanoshimensis from Indonesia contained a hyperparasitic isopod ( Cabirops sp. ) in brood chamber.
