Phyllopodopsyllus briani Petkovski, 1955 



PhyllopodopsT/llus briani Petkovski, 1955, p. 126, figs. 1-13; 1957, p. 9. 



Described by Petkovski from female and male specimens from 

 Budva, Herceg Novi, and probably also Dubrovnik on the Adriatic 

 coast of Yugoslavia. 9 0.70 mm.; cf 0.50 mm. An inhabitant of 

 interstitial water masses of sandy beaches. 



Phyllopodopsyllus thwbaudi Petkovski, 1955 



PhT/llopodopsyllus thiebaudi Petkovski, 1955, p. 130, figs. 14-20; 1957, p. 9. 



Described by Petkovski from female and male specimens from 

 Herceg Novi on the Adriatic coast of Yugoslavia; subsequently 

 found also at Dubrovnik on that coast. 9 0.70 mm.; cf 0.65 mm. 

 Also living in the interstitial water of sandy beaches. 



There is a very striking resemblance between Phyllopodopsyllus 

 thiebaudi and Paraphyllopodopsyllus intermedins Noodt (1955b, p. 97, 

 figs. 49-66). The very characteristic furcal structure is identical 

 in both forms, as is the structure of leg 5. The only difference in 

 setation is found in the exopodite of leg 4: P. thiebaudi apparently 

 has 3 setae at the internal margin; P. intermedius, 2. Noodt states 

 emphatically that in his new form there is no tooth on the 2nd anten- 

 ular segment; it should be remembered that in P. thiebaudi this 

 tooth is no more than a small knob. 



Phyllopodopsyllus pauli Crisafi, 1960 



Phyllopodopsyllus pauli Crisafi, 1960, p. 495, figs. 1-8. 



Female specimens of this species were described by Crisafi from 

 Cape Tindari, Gulf of Patti, Sicily, Mediterranean Sea, a brackish 

 water habitat with very changeable salinity, where the species appar- 

 ently lives on the sandy bottom. The furcal structure is very peculiar 

 and quite different from the other members of this genus. 



Family Canthocamptidae G. O. Bars, 1906 



Representatives of only two genera, Orthopsyllus Brady and Robert- 

 son, 1873, and Nannomesochra Gurney, 1932, are present in the col- 

 lection. 



Genus Orthopsyllus Brady and Robertson, 1873 



I have accepted Lang's suggestion to consider Lilljeborgia linearis 

 Glaus, 1866, as a clearly defined species and as the typo species of 

 Orthopsyllus. Jakobi (1954) recently has introduced the genus Ka- 

 tacletodes as a new genus of the Cletodidae. A study of his figures and 

 particularly of the setal formula of the species attributed to this 

 genus, K. improportionatus, clearly shows that Katacletodes is a
