[Vol. 91 
Female. Total length 5.87 ±0.65 mm; carapace 2.83 ±0.32 mm 
long and 2.19 ±0.32 mm wide (20 specimens). General color and 
structure as in male but paler, with the abdominal dorsum having 
only scattered black spots on a yellowish background. Median 
septum extending anteriad nearly to level of hood, rather broad 
anteriorly (Fig. 60); copulatory tubes short, slender, with lateral 
swellings (Fig. 61). 
Diagnosis. Specimens of P. littoralis are unique in the milvina 
group by the greatly elongated terminal apophysis and by the 
anteriorly broad median septum. 
Range. Texas to Florida, northward near the coast to the Bay of 
Fundy, Nova Scotia; Cuba. 
Natural History. Both sexes of P. littoralis have been collected in 
every month in the southern part of its range, and egg sacs were 
observed in April, June to August, and December. In general it is an 
inhabitant of salt marshes, though Florida records include beaches, 
lake shores, pine-oak forests, and swamps. One specimen was 
collected in a soybean field. Muma (1973) trapped many in pine flat- 
woods, and lesser numbers in a sand-pine dune or in citrus groves. 
Courtship behavior was described (under the name banksi ) by 
Kaston (1936). The present authors observed adults running on a 
salt marsh in Nova Scotia on a warm day at the end of May, 1980. 
Males and females were seen on or under the mat of dry marsh 
grasses, particularly at the water’s edge where the mud was wet from 
the previous tide. If overtaken by a wave they either ran on its 
surface or climbed emergent plant stems. 
Comments on Synonymy. This spider has been variously known 
under five specific names, one of which was proposed on the 
assumption that the name littoralis was preoccupied in Pardosa. 
Chamberlin (1904) apparently did not realize that the name Lycosa 
littoralis Walckenaer, 1805 was a nomen nudum and, therefore, not 
available. He was apparently also unaware of the older available 
names Pardosa longispinata Tullgren, 1901 and Pardosa floridana 
Banks, 1904.
