Remarks

Parapenaeon japonica is a very widespread species, and was reported from the Red Sea through the Indian Ocean past Pakistan and India to Japan, the Philippines and China, including Hong Kong. This species has been thoroughly described and illustrated, and some aspects of its biology have been studied ( Hiraiwa 1933, 1934, 1936). Shiino (1950) transferred it to the genus Apopenaeon as A. japonicum because its female has six pleomeres. Bourdon (1979a) later transferred this species to Parapenaeon as P. japonicum . In recording it from Indonesia, the Philippines and near Madagascar, Markham (1994) diagnosed its characters; the most distinctive feature of the female is that its short side bears coxal plates on only the first two pereomeres. Kazmi and Tirmizi (1994) reported P. japonica from Pakistan but illustrated the female with coxal plates on both sides of all pereomeres; therefore they actually had Parapenaeon expansa (discussed below) instead.

The present specimens display a moderate amount of morphological variation. Although a female ( Figure 1 ) infesting M. toloensis Hall conforms well to the description of those from Hong Kong ( Markham 1982), its accompanying male ( Figure 1M, N ) is more similar to that from Madagascar ( Bourdon 1979a: fig. 6m). Among parasites ( Figure 2) of M. stridulans , the posterior margin of the first oostegite ( Figure 2F, G) of one female is unusual, and its male ( Figure 2H) has black eyes. A female ( Figure 3A–H) infesting M. barbata (de Haan) has many small differences, internal ridge of oostegite 1 simple and palp stout and straight. At the same time, the pleon of its male has a large midventral tubercule ( Figure 3J). In another male ( Figure 3N), the pleon is separated into three pleomeres rather than being unsegmented.

The host species M. toloensis , M. dura , M. mogiensis and M. novaeguineae have never before been reported to bear bopyrid parasites, whereas M. stridulans have been reported to bear Epipenaeon ingens Nobili, 1906 and Orbione thielemanni Nierstrasz and Brender à Brandis, 1931. With the addition of the new host records, P. japonica is now known to infest 21 different penaeoid host species, the most for any orbionine bopyrid species. It is also the most widespread geographically of any orbionine species.
