Fig. 29. Paraugaptilus similis, female (A-D), male (E-H). A, Antennary exopod; B, Second endopod segment of antenna; C, Mandibular 

 exopod; D, Basal spine of maxilla; E, Antennary exopod; F, Detail of antennary exopod segments IV to X; G, Second endopod segment of 

 antenna; H, Mandibular exopod. Scales in mm. 



pletely fused with segments XXIV-XXV; segments XXV and 

 XXVI incompletely fused; left compound segment 

 XXVI-XXVIII with 7 setae and aesthetasc. 



Antenna: second endopod segment about 1.9 times as long 

 as first, with 1 minute inner seta at mid-length and 5 setae and 

 1 vestigial seta terminally, as in P. similis; exopod similar in 

 segmentation and setation to that of female P. similis. 

 Mandibular palp: first exopod segment with vestigial seta 

 (Fig. 32B) as in female P. similis. Maxilliped: sixth endopod 

 segment (Fig. 32E) similar to that of P. similis, but seta c with 

 terminal spinules incompletely fused to seta. 



Male. Left antennule (Fig. 32F) with same fusion pattern 



and armature as in P. similis except for following: seta on 

 segment XXII not modified into process; process on segment 

 XXIV-XXV not so developed as in male P. similis, not 

 reaching beyond end of antennule, directed straight for- 

 wards. Antenna similar in segmentation and setation to that 

 of female; second endopod segment ca. 1.4 times as long as 

 first. Mandibular palp: first exopod segment with well- 

 developed seta (Fig. 32G). Maxillule: praecoxal arthrite (Fig. 

 32C) with 5 spines; tubular gland opening on inner surface. 



Leg 5: both coxae and intercoxal sclerite completely fused 

 as in male P. similis; coxa and basis separate in left leg and 

 incompletely fused in right (almost completely fused on
