the segment on leg I. Abdomen elongate and narrow, tapering from 
front to rear; pale above and below, with a pair of submarginal brown 
bands along the sides. 
Tibia of palpus about equal to patella in length, approximately 
uniform in thickness. Lateral apophysis a small, erect hook (Fig. 2). 
Ventral apophysis slightly longer than the lateral apophysis, rounded 
apically (Fig. 15). 
Female: total length 3.82 zb 0.37 mm; cephalothorax 1.40 zb 0.07 
mm long and 1.15 zb 0.07 mm wide; femur II 1.53 zb 0.12 mm long; 
ocular quadrangle 0.25 zb o.oi 1 mm long and 0.63 zb 0.015 mm wide. 
These data are the means and standard deviations from a sample of 
nine females. Shape and color as in the male. Tibiae I and II spilled 
as in the male, but some specimens with one or two additional pairs 
of weak spines in the distal half. Basitarsal spination as in the male. 
Femur I with from none to four weak dorsal spines and one or two 
prolaterals. Abdomen colored as in the male, but not tapered. Median 
plate of epigynum U-shaped with a sword-shaped piece extending over 
it from in front (Fig. 10). Spermathecae oval, situated well in front 
of the genital groove (Fig. 13). 
Range. Florida south of approximately 28° north latitude. 
Florida Localities. Dunedin; Royal Palm Park; St. Petersburg; 
Mallet Key; Lake Placid; Fish Eating Creek, Glades County. 
Comments. Gertsch (1933) erected the new genus Tibellomimus , 
the type of which was T. lineatus Gertsch, for this species. His publi- 
cation was followed closely by Bryant’s (1933), however, in which 
both sexes of the same species were described as Philodromus bilineatus. 
Gertsch later ( 1934) recognized the synonymy of the two species, but 
retained the genus Tibellomimus. Roewer (1954) correctly cited the 
species as Philodromus bilineatus , lineatus being preoccupied in the 
genus Philodromus. The basic arrangement of the eyes and structure 
of the external genitalia relate this species to the rufus group, while 
its nearly rectangular carapace and elongate, striped body appear to be 
superficial modifications.
