Material examined

Cape d’Aguilar , Hong Kong Island, Gelidium pusillum beds, 11 females, 4 males, 1 juvenile, NHM Reg. Nos. 2004.2932–42 .

Remarks

This species has been recorded previously from Chinese waters and appears to resemble most closely the form of the Florida male specimen figured by Laubitz (1972), and that illustrated by Guerra-Garcia and Takeuchi (2002) from North Africa. However there are problems with Caprella penantis since it is likely to be a complex of many different species (the old complex C. acutifrons ). There is no complete recent redescription of Caprella penantis . The peduncle of antenna 1 of the Hong Kong species is closer to C. andrae and C. dilatata , the pereopods and particularly the gnathopod 2 are also different. Eventually this entity may be given specific status but a thorough revision of the complex is required, which is beyond the scope of this work.
