Pinnotheres orientalis White, 1847 , Pinnotheres orientalis Adams, 1847 and Pinnotheres orientalis Woodward, 1886 ( Decapoda : Brachyura : Pinnotheridae )

The name Pinnotheres orientalis has been used by three separate authors. White (1847a: 127) listed: “ Pinnotheres orientalis . a. Borneo (Unsang). Presented by Capt. Sir Edw. Belcher, C.B., R.N.”. Adams (1847c: 353), stated: “I have detected a species of Pinnotheres , hitherto undescribed ( P. orientalis, Adams and White ,) that inhabits the large Avicula so common in these seas”. Woodward (1886: 177) stated: “There is a large series of Pinnotheres in the Museum: the one from Australia is referred to P. orientalis , but as these are all females comparison is useless. These are from shells of Pinna , Donax , and Pectunculus . There are others from Broken Bay”. All three uses of Pinnotheres orientalis are nomina nuda.

The record of Pinnotheres by Woodward (1886) from Australian bivalves is significant as it is “possibly the oldest published reference to pinnotherids infecting the bivalve molluscs Glycymeris sp. ( Glycymerididae ) and Donax sp. ( Donacidae ) in Australia ” (see Ahyong & Brown 2003: 9). Shane T. Ahyong (pers. comm.) believes that the “large series […] from Australia [which] is referred to P. orientalis ” as well as the P. orientalis of White (1847a: 127) and Adams (1847c: 353) are synonymous with Nepinnotheres villosulus (Guérin-Méneville, 1838) . As the distribution of this species agrees well with the localities (i.e., Australia to Borneo) mentioned by Adams (1847c), White (1847a), and Woodward (1886). The unnamed specimens from Broken Bay of Woodward (1886) can be referred to Pinnotheres hickmani ( Guiler, 1950) , as this is the only species of Pinnotheres found in that locality.

The following nomina nuda are identified with Nepinnotheres villosulus (Guérin-Méneville, 1838) : Pinnotheres orientalis White, 1847 , and Pinnotheres orientalis Adams, 1847 , and Pinnotheres orientalis Woodward, 1886 .
