FISHERY BULLETIN: VOL. 78, NO. 3 



with two patches of scalelike spinules; coxopod 

 with broad, inner plumose seta and outer 

 sclerotized spine; basipod with several rows of 

 small, scalelike spinules above insertion of en- 

 dopod; exopod 2 -segmented, first segment with 

 outer, stout, flagellated spine, second segment 

 with three outer setiform spines and six terminal 

 to inner plumose setae; endopod 2-segmented, first 

 segment with inner seta, second segment with six 

 inner to terminal setae. Basipod of leg 2 (Figure 

 26) with ventral patch of scalelike spinules and 

 dorsal seta; first segment of exopod with large 

 patch of scalelike spinules along outer half of seg- 

 ment and setiform spine on outer distal corner; 

 second segment with 1 or 2 rows of stout spinules 

 along outer edge and one outer spine, third seg- 

 ment with row of stout spinules along outer edge, 

 two outer spines, one barbed terminal spine, and 

 three inner setae; first segment of endopod with 

 scalelike spinules along outer edge and short 

 inner seta, second segment with scalelike spinules 

 along outer edge and two inner setae, third seg- 

 ment small, with three setae (innermost longest). 

 Leg 3 (Figure 27) similar to leg 2 with following 

 exceptions: basipod lacks ventral patch of 

 scalelike spinules; second segment of endopod 

 with only one seta; outermost seta on endopod 

 third segment reduced to a setule. Leg 4 (Figure 

 28) similar to leg 3 except middle seta of endopod 

 third segment longest (about three times longer 

 than innermost). Leg 5 (Figure 29) basal segment 

 with dorsal seta; free segment slightly inflated 

 with one outer seta and three terminal setae (mid- 

 dle seta longest); no surface ornamentation vis- 

 ible. Leg 6 represented by three setae at area of 

 egg sac attachment (see Figure 19); setae reach to 

 about middle of first abdominal segment. Egg sacs 

 flattened in most specimens. (The egg sacs of 

 ovigerous females of bomolochids parasitic in the 

 orbit of their hosts are typically flattened. The egg 

 sacs of a few specimens of this new species were 

 more rounded.) 



Male. — Unknown. 



Remarks. — Our description of this species is in 

 general agreement with Pillai's (1971) redescrip- 

 tion with the following exceptions on specific 

 points. We found the segmentation between the 

 second and third abdominal segments less distinct 

 than did Pillai. Pillai failed to mention the or- 

 namentation on the ventral surface of the last 

 abdominal segment and caudal rami. We found the 



first antenna to have one more segment than did 

 Pillai. The last segment of the second antenna has 

 four hooked spines and two setae rather than "5 

 claws and one stiff seta" as stated by Pillai. The 

 maxilliped hook has a small but noticeable inner 

 tooth. The basipod of leg 2 has a patch of scales not 

 present on the basipods of legs 3 and 4. While these 

 points are relatively minor, they aid in defining 

 the species. 



P seudorbitacolax nudus 

 (Cressey and Boyle 1973) (Figures 30-35) 



Syn: Orbitacolax nudus Cressey and Boyle 

 1973:6. 



Originally reported from Herklotsichthys 

 punctatus from the Philippines. Additional collec- 

 tions of 4 9 from the same host species and locality 

 (BM 1933.3. n:15-16, BM 1933.3.11:17-18). 



Our redescription oi P seudorbitacolax enabled 

 us to reassign Orbitacolax nudus to this genus. 



Figure 30 (SEM photo) reveals the presence of 

 ridges on the surface of the dorsal cephalic hooks. 

 Figure 32 shows the surface of the tip of the second 

 maxilla to be covered with closely packed spinules. 

 Figure 34 shows the spinules on the exopod of leg 2 

 to be somewhat blunted. The spinules on the ter- 

 minal spines of legs 2-4 are hooklike (Figure 35) 

 and similar to those commonly found on the second 

 antenna. 



Pumiliopsis Pillai 1967 



Diagnosis. — Bomolochidae. Female: Body 

 dorsoventrally fiattened. Rostrum bilobed. Dorsal 

 cephalic hooks present; ventral rostral hooks may 

 or may not be present. Thoracic segments nar- 

 rower than cephalothorax. Abdomen elongate, 

 segmentation indistinct. Caudal rami each with 

 one long, five short setae. First antenna with no 

 modified setae. Second antenna typical of family, 

 terminal segment with several rows of booklets, 

 four hooked spines, and two setae. First maxilla 

 with three setae, middle seta more than twice the 

 length of other two. Maxilliped hook with no outer 

 accessory process, inner process may be present. 

 Legs 1-4 biramous, rami 2-segmented, except en- 

 dopod of leg 4 3-segmented. Leg 1 rami flattened. 

 Last exopod segment of legs 2-4 with barbed spine. 



Male. — Rostrum slightly produced. Thoracic 

 segments each narrower than preceding segment.
