NO. 3570 PANDARIDAE — CRESSET 25 



Phyllothereus Norman, 1903, p. 368. 

 Parapandarus Wilson, 1924a, p. 7. 



Female. — Frontal plate distinctly separate. Fii-st thoracic seg- 

 ments 2-4 free and possessing dorsal plates. Dorsal plate of segment 

 3 extending well beyond distal margin of plates of segment 2. Plates 

 of segment 4 separated. Abdomen 1-segmented and with a dorsal 

 plate. Abdomen or its plate visible dorsally and attached to distal 

 end of genital segment. Caudal rami lateral to abdomen. First 

 antenna 2-segmented. Claw of maxilliped pointed at tip. Adhesion 

 pads absent or much reduced. Legs 1-4 biramose, rami of legs 1-3 

 2-segmented, those of leg 4 1-segmented. All legs without plumose 

 setae. Leg 5 present. Egg sacs long and straight. 



Male. — No dorsal plates present. Cephalic appendages in general 

 like those of female. Legs 1-4 biramose, all rami 2-segmented bearing 

 plumose setae. Fifth and sixth legs present. Leg 3 endopod un- 

 modified. Abdomen 2-segmented. Caudal rami held at distal end 

 of abdomen. Adhesion pad with first antenna. 



Discussion. — A great deal of confusion has existed over the 

 synonjTny of this genus. The genus was first described by Milne- 

 Edwards in 1840 as Phyllophora with P. cornutus as the type-species. 

 Later, in 1861, Steenstrup and Lutken described the male as Nogagus 

 grandis. Norman (1903) cited the fact that Phyllo'phora is thrice 

 preoccupied and changed the generic name to Phyllothereus. Wilson 

 (1907) discussed the preoccupation of the name Phyllophora and 

 stated that Poche in 1902 suggested changing the name to Laminifera. 

 This reference to Poche (1902) is in error since there is no reference 

 to the name Laminifera by this author in 1902 or in subsequent works 

 (see Brian, 1946). Brian synonymized his Laminifera doello-juradoi 

 with P. cornutus in 1946; consequently, the valid name of the genus 

 should be Phyllothereus as proposed by Norman in 1903. Wilson 

 in 1932 states that his Parapandarus is so close to Phyllothereus that 

 the 2 may be identical. I have examined Wilson's types of 

 Parapandarus and have concluded that they are indeed the same; 

 consequently, P. nodosus Wilson 1924 is synonymous with Phyllothereus 

 cornutus (MUne-Edwards, 1840).
