 caudal (Figure 61D) and frontal surfaces (Figure 61E) and with 

 spinular row on caudal surface, near base of inner setae as figured. 



Palp of mandible (Figure 62C) represented by 3 naked setae. 2 of 

 which very long, third seta short. 



Legs 1 to 3 each without mid-distal spinular on posterior surface 

 of coxa; without spinular row on anterior surface of intercoxal 

 sclerite (Figure 63A,B,C). Inner coxal spine of leg 4 with group of 

 setules mainly originating posteriorly. Exopodal segments 1 and 2

Leg 5 (Figure 63E) comprising single free segment, armed with 1 

 strong inner spine with spinules at base and 2 plumose setae about 

 same length; bases of setae produced. Leg 6 (Figure 61 B) repre- 

 sented by 1 naked seta and 2 tiny spinules dorsolaterally. 



Description of adult male 



Mean body length 552 urn (n=2), mean body width 250 urn (n=2). 



Outer lateral seta (III) of caudal rami naked (Figure 3.93B,C). First 



segment of antennule armed with 8 setae plus aesthetasc; 1 seta (A) 



large and modified by ornamentation of strong spinules in mid 



section. 



All other appendages as in female except for fifth and sixth legs 

 (Figure 64C). Outer plumose seta of leg 5 shorter than in female. 

 Sixth legs armed with 1 inner spine, 1 outer naked seta and 1 well 

 developed spinulose seta in centre. The inner spine of the left leg 5 

 of a paratype male was abnormal (Figure 64D). 



ETYMOLOGY. The new species is named in honour of Dr. Janet 

 Reid who made the specimens available for study, in recognition of 

 her contributions to cyclopoid systematics. 



Differential diagnosis. The new species can easily be differen- 

 tiated from all species in the genus by the structure of leg 5 in both 

 sexes (Figures 63E; 64E), by the absence of a dorsal spinular row 

 either side of anal somite (Figure 6 IB), by the spinular ornamenta- 

 tion of the coxobasis of the antenna on caudal and frontal surfaces 

 (Figure 61D,E), by the shape of the caudal rami and the structure of 

 its setae in both sexes (Figure 61 A,B) and by the lengths of the distal 

 antennulary segments measured along the posterior margin in the 

 female (Figure 62A). 



Remarks 



P. reidae, P. altissimus (Karaytug et al., in press) and P. hardingi 

 nom. nov. are closely related. The three species lack a spinular row 

 on the posterior surface of the first and second exopodal segments of 

 legs 1-3 and possess a spinular row near the base of the two inner 

 setae on the antennary coxobasis in both sexes. However P. reidae 

 can easily be differentiated from P. hardingi and P. altissimus by the 

 relative length of the antennulary segments, the length and spinulation 

 of the outer seta of leg 5, the structure of seminal receptacle and in 



having the terminal accessory seta (VI) about 2 times longer than the 

 caudal rami.

Description of adult female 



Body length and width measurements given in Table 5. Urosomal 

 somites without surface pits on dorsal and ventral surfaces except 

 genital double-somite with very fine surface pits on dorsal surface as 

 figured (Figure 65 A). Seminal receptacle (Figure 65B) with poste- 

 rior lobe wider than anterior as figured. Caudal rami (Figure 65A.B) 

 about 2.5 times longer than broad, with inner margin slightly convex 

 distally. Terminal accessory seta (VI) plumose and 1.3 times longer 

 than posterolateral seta (III); outer terminal seta (IV) and inner 

 terminal seta (V) well developed and heterogeneously ornamented 

 (Figure 65B). 



Antennule 8-segmented (Figure 66A). Segment 3 with partial 

 suture line and spiniform seta. Setal formula 8, 12. 6, 5. 2 + 

 aesthetasc. 2, 2 + aesthetasc, 7 + aesthetasc. Coxobasis of antenna 

 with complex ornamentation on caudal (Figure 66C) and frontal 

 (Figure 66B) surfaces as figured, and without spinular row on caudal 

 surface near base of two inner setae (arrowed in Figure 66C). 



Basis of leg 1 (Figure 67D) with setiform spine on inner margin 

 reaching halfway along terminal endopodal segment; intercoxal 

 sclerite ornamented with spinular rows on anterior and posterior 

 surfaces (Figure 67D). Intercoxal sclerite of leg 2 ornamented with 

 spinular rows on anterior (Figure 67A) and posterior (Figure 67B) 

 surfaces; coxa without mid-distal spinular row on posterior surface 

 (arrowed in Figure 67B). Intercoxal sclerite of leg 3 without spinular 

 row on anterior (Figure 68 A) surface and with 2 spinular rows on 

 posterior (Figure 68B ) surface; coxa without mid-distal spinular row 

 on posterior surface (arrowed in Figure 68B). Intercoxal sclerite of 

 leg 4 with 2 spinular rows on posterior (Figure 68D) surface, without 

 spinular row anteriorly (Figure 68C).
