a NSW = New South Wales, Qld = Queensland. 
b Transferred to Acutiramus, see Walker-Smith (2001). 
c Placed in Acutiramus by Harris & Robertson (1994). Specimens labelled Porcellidium acuticaudatum in the NHM collection (1928.4.2.43) from 
Lake Timsah, Ismalia do not have T2 or T3 on the trapezoid caudal ramus—diagnostic characters for Kensakia. 
d Walker-Smith confirms that the male antennule is characteristic of Murramia (personal communication). 
The following may be valid species, but are omitted from this list because their description does not allow them to be placed in a genus; they 
require redescription, (fulvum and interruptum Thomson, 1882, tuberculatum Wolfenden, 1905, scotti Pesta, 1935 and malleatum Vervoort, 1964). 
The species recorded from South Australia by Nicholls (1941) cannot be identified from his descriptions and are not considered here. 
Many species occur in large populations on particular 
species of algae or sea grass, for example Porcellidium 
hormosirii is abundant on Hormosira banksii , the dominant 
mid-littoral alga on the NSW coast, but neither species are 
found at Hervey Bay. P. phyllosporum has only been found 
on Phyllospora commosa and P. naviculum on Cystophora 
moniliformis. Tectacingulum nigrum and Murramia bicincta 
are only found on other species of Cystophora common on 
the southern coast of NSW. From Sydney to the northern 
coast of NSW Dilatatiocauda multidenticulata is abundant 
on Sargassum which replace the Cystophora species. This 
shows that porcellidiid copepods tend to select particular 
seaweeds, consequently their distribution will be influenced 
by the distribution of algal species.

Facility, Australian National University, Canberra, for her helpful 
advice and permission to use the Hitachi S-255 scanning electron 
microscope on which the SE micrographs of Cereudorsum 
verrucosum (Plates 1 and 2, pp. 172-173) were taken.
