 lives in and near very wet habitats and can get to be 10 mm long.

The species is abundant in the maritime drift line in and near Beau- 

 fort, and is especially abundant on and under old planks, stones and 

 other detritus beneath dead plant matter. Philoscia vittata occurs fre- 

 quently with A. ellipticus in the dead vegetation. The species has been 

 found all along the east coast of the United States, from Woods Hole, 

 Massachusetts, to south Florida. It is small and does not run when dis- 

 turbed, but instead clings to the bottom of hard substrates where it 

 remains long after the habitat has been disrupted. Because of its small 

 size (to 3.5 mm long), elliptical shape, and the four flagellar articles on 

 antenna 2 (Fig. 3), it cannot be confused with other species of the shore.

Confusion about the name and identification of this species was 

 reviewed by Schultz (1974) who clarified some misidentifications on 

 which his own error was based. Although the species probably does not 

 belong in Philoscia Latreille (Old World species only?), it should be 

 kept in the genus until all halophilic members of the Philosciidae from 

 the New World are reviewed. The species lives under dead seaweed and 

 detritus of the maritime drift, at the upper part of the beach and edges 

 of marshes along inland bays. It lives in the grasses of high tide washes 

 and swamps wet with tidal water. 



The species is always taken near and often with Armadilloniscus 

 ellipticus, but is much more active and less secretive than that species. 

 Some ecology of the species in the Beaufort region was recorded by 

 Schultz (1963). I took the species at Hammocks Beach State Park, 

 North Carolina (Map 3), and it has been recorded on the coast of Geor- 

 gia (Schultz 1975), including St. Catherines Island (Schultz 1977). Male 

 pleopods 1 are large, with the apexes of the distal portion of the endo- 

 pods folded laterally (Fig. 5), setting the species apart from others in the 

 genus (see Schultz 1974 for comparisons). It ranges to 5 mm long.
