Anyphsena johnstoni Chamberlin, Proc. Cal. Acad., 1924. 
12, p. 662, f. 105, 106. Gulf of California. 
Found in Louisiana, Texas and California. This species 
may prove to be Aysha simplex Cambridge, Biol. Cent. 
Amer., 1897, 1, p. 227, pi. 29, f. 4, 5. Panama, Veraguas. 
Cambridge says, “Palpi, short, slender, cubital joint short, 
not half the length of the radial, which is very lightly 
curved, cylindrical, furnished with a few long, slender 
spine-like bristles, and has a tapering somewhat sinuous 
reddish-yellow brown apophysis projecting nearly at right 
angles to the joint at its fore extremity on the outer side. 
This apophysis is longer than the width of the joint.” 
In the Spiders of Porto Rico, Trans. Conn. Acad. ; 1930, 
31, p. 61, Mr. Petrunkevitch has placed Aysha simplex 
Cambridge as a synonym of Aysha tenuis L. Koch. From 
the number of specimens in the Museum of Comparative 
Zoology collection from various islands in the West Indies, 
the tibia of the male palpus of Aysha tenuis is longer than 
the tarsus, and at least five times as long as the diameter ; 
there is but one tibial apophysis, not two, which is com- 
paratively short, the embolus occupies the upper half of 
the palpal organ. 
From the two figures of Aysha simplex Cambridge, the 
tarsus is longer than the tibia, which is about three times 
the diameter; there are two apophyses and the embolus 
occupies more than half the palpal organ. It differs from 
Aysha decepta (Banks) by the shorter upper apophysis 
and the relatively smaller palpal organ. 
Aysha nigrifrons (Chamberlain and Woodbury) 
Anyphsena nigrifrons Chamberlain and Woodbury, Proc. 
Biol. Soc. Wash.; 1929, 42, p. 137, pi. 1, f. 4. $ “Utah, 
St. George, Dec. 1925.” 
The figure of the epigynum, number of teeth on the 
inferior margin of the mandibles and number of spines on 
the anterior metatarsi show that this species is an Aysha 
rather than Anyphsena.
