Pseudocyclops reductus Nicholls, 1944 



Pseudocyclops reductus Nicholls, 1944a, p. 488, fig. 1. — Noodt, 1958a, p. 156. — 

 Bowman and Gonzdlez, 1961, p. 58. 



This species is described rather cursorily in Nicholls' paper and 

 only the antennule, antenna, 5th legs, and abdomen are figured. 

 Setal formulae for all legs fortunately are given; the species is said 

 to approach P. australis very closely. 8 female specimens, varying 

 in length from 0.50 to 0.60 mm., were found at Hurghada on the 

 Red Sea. 



Pseudocyclops gohari Noodt, 1958 



Pseudocyclops gohari Noodt, 1958a, p. 151, figs. 1-14. 



This very distinct and curious species was described recently by 

 jNToodt on the basis of many adult male and female specimens from 

 Hurghada on the Red Sea, where it was found in small pockets of 

 sand between sand-in crusting algae of the littoral zone. 9 0.95 

 mm.; cf 1.0 mm. 



Pseudocyclops cokeri Bowman and Gonzdlez, 1961 



Pseudocyclops cokeri Bowman and Gonzdlez, 1961, p. 41, figs. 1-3. 



A large number of females and males of this species were obtained 

 in Magiieyes Channel between Magiieyes Island and an area near 

 La Parguera, Puerto Rico. It was found living in great numbers 

 between algae attached to the leaves of turtle grass, Thalassia 

 testudinum. 9 0.5-0.6 mm.; cf 0.45-0.55 mm. 



Pseudocyclops paulus Bowman and Gonzalez, 1961 



Pseudocyclops paulus Bowman and Gonzdlez, 1961, p. 46, figs. 4, 5. 



Found in smaller numbers at the same locality and under compa- 

 rable conditions as P. cokeri. This is an exceedingly small species. 

 9 0.40-0.42 mm.; cf 0.37-0.43 mm. 



Pseudocyclops rostratus Bowman and Gonzalez, 1961 



Pseudocyclops rostratus Bowman and Gonzdlez, 1961, p. 49, figs. 6-8, 9g. 



Some specimens of this curious form were found between P, cokeri, 

 P. paulus, and P. ruhrocinctus at the same locality as these species. 

 It is particularly characterized by the strongly developed rostrum. 

 9 0.72-0.76 mm.; cf 0.72 mm. 



Pseudocyclops ruhrocinctus Bowrman and Gonzalez, 1961 



Pseudocyclops ruhrocinctus Bowman and Gonzdlez, 1961, p. 54, figs. 9a-f, 10, 11. 

 Collected together with P. cokeri and P. paulus at the same locality; 

 it probably lives under the same conditions as these species. In its 

 living state it is brightly colored. 9 0.55-0.62 mm.; cf 0.50 mm.
