NO. 3656 COPEPODS—LEWIS ao 
3 setae. Second segment rodlike, with single naked setule from middle 
of segment, approximately 9 naked setules from distal surface. 
Antenna (fig. 14e) 3-segmented, situated posterior and slightly medial 
to antennule base. First segment generally ringshaped, heavily 
sclerotized, with spikelike projection from posterior surface. Second 
segment well developed, broader proximally than distally. Third 
segment and clawlike terminal process continuous, with knoblike 
articulation surface proximally and knoblike projection on medial inner 
surface; accessory processes not evident. 
Mandible (fig. 14e) 4-parted, rodlike, distalmost part denticulated 
along inner margin. Postantennal process evident as small, lightly 
sclerotized area surrounded by ringlike area of heavy sclerotization 
situated lateral and posterior to antenna base, area with 3 nodule-like 
structures although ‘‘typical’” hairlike processes not evident. Postoral 
process absent. Postoral adhesion pad present as barshaped projection 
of heavily sclerotized rod in sternal region, immediately anterior to 
maxilliped base. Maxillule (fig. 14¢) minute, nodular, situated lateral 
and posterior to mouth cone, slightly posterior to antennal base. 
Nodule bearing 2 poorly sclerotized, naked setae. Maxilla (fig. 14/) 
2-segmented, situated posterior and lateral to maxillule, adjacent to 
(though not associated with) large, naked seta (maxillary whip of 
Kabata, 1965b). First segment approximately one and one-fourth 
times the length of second, elongate, tapered to minutely bilobed 
proximal articulation process. Second segment elongate, with small, 
spikelike subterminal process and long, setalike terminal process. 
Manxilliped (fig. 14g) 2-segmented, situated medial and slightly 
posterior to maxilla base. First segment well developed, proximal end 
narrow, recurved slightly. Second segment incompletely separable 
from clawlike terminal process, accessory process not evident. Sternal 
furca absent. 
Thoracic legs I-III biramous although endopodite of first leg 
rudimentary, fourth thoracic leg uniramous, small, poorly sclerotized, 
3-segmented. For nature and armature of thoracic legs, see figures 
15a—e and table 6. 
Discusston.—The female of Pseudanuretes pomacanthi, new species, 
differs from the females of the two other recognized members of the 
genus, P. chaetodontis Yamaguti (1936) and P. fortipedis Kabata 
(1965b) (for a note on P. schmitti Rangnekar, 1957, see below), in 
two respects: 
1. The antenna is simple and does not have an accessory spine. 
2. The structure and armature of the fourth thoracic leg. The leg 
of P. pomacanthi is similar in structure to that of P. fortipedis but has 
2 terminal setae instead of 1 The leg of both species is either 2- or 
3-segmented while that of P. chaetodontis is only 1-segmented.
