CRESSEY and CRESSEY: BOMOLOCHID COPEPODS PARASITIC ON EYES OF CLUPEIDS 



net. The first endopod segment of leg 3 does have a 

 very short inner spinule. The last endopod seg- 

 ment of leg 4 has a small outer seta in addition to 

 the two mentioned by Bennet. Leg 5 has a total of 

 four setae on the terminal segment, one on the 

 midouter margin and one subterminally in addi- 

 tion to the two terminal setae Bennet noted. 



The scanning electron micrographs of the 

 female indicate the hooklike nature of the or- 

 namentation on the second antenna (Figures 43, 

 44) and the bifurcate tips on the lateral hairs on 

 the endopod of leg 4 (Figure 46). 



Pumiliopes Shen 1957 



Diagnosis: — Bomolochidae. Female: Body dor- 

 soventrally flattened. Rostrum only slightly pro- 

 duced, rounded, broader than long. Thoracic seg- 

 ments bearing legs 2-5 free, each segment slightly 

 narrower than preceding one. Genital segment 

 wider than last thoracic segment. Abdomen 

 3-segmented, segmentation may be indistinct. 

 Caudal rami each with one long and five short 

 setae. Neither dorsal cephalic nor ventral rostral 

 hooks present. First antenna with no modified 

 setae. Second antenna 3-segmented, last segment 

 subdivided; subterminal portion with 1 or 2 rows of 

 booklets and one stout claw, terminal portion with 

 three hooked spines and two setae. First maxilla 

 with no or three short setae. Second segment of 

 second maxilla produced posteriorly. Maxilliped 

 hook with no accessory processes. Legs 1-4 bi- 

 ramous. rami 2 -segmented except leg 4 endopod 

 3-segmented. Leg 1 rami flattened. Last segment 

 of exopod of legs 2-4 with smooth, stout, clawlike 

 spine. 



Male. — Unknown. 



Type-species. — Pumiliopes opisthopteri Shen 1957. 



Remarks. — In Shen's (1957) description of P. opis- 

 thopteri he reported no setae on the first maxilla, 

 and based on that report we have included it in the 

 generic diagnosis. This condition, however, is 

 unique in bomolochids; therefore, we consider 

 Shen's description of the first maxilla to be tenta- 

 tive until additional material of this species can be 

 examined. 



Pumiliopes opisthopteri Shen 1957 

 Originally described from the "left eye" ofOpis- 



thopterus tardoore from Yin-ku Bay, Hainan Is- 

 land, China. This copepod has not been reported 

 since and we did not recover specimens in our 

 examination of 24 specimens of the original host 

 species (including specimens from China). 



Pumiliopes jonesi (Bennet 1967) 



Syn: Bomolochus jonesi Bennet 1967:132. 



Pumiliopes capitulatus Cressey and Boyle 

 1973:1. 



Bennet originally described this copepod as 

 Bomolochus Jonesi from a collection of over 200 

 specimens collected from under the adipose eyelids 

 of Rastrelliger kanagurta (Scombridae) from 

 Calicut, India. In 1973 we collected the same 

 species of copepod, which we reported as P. 

 capitulatus, from the orbit of Clupanodon 

 punctatus (a clupeid). Our additional collections 

 from clupeids include 1 9 from C. punctatus (BM 

 93.4:21-28) from Hae-yoe Chi Kiang and 3 9 from 

 Herklotsichthys displonotus (BM 1967.11.13:1-9) 

 from Singapore. 



We also recovered 35 females from the orbits of 

 the following scombrid fishes (all USNM collec- 

 tions): 17 from R . kanagurta from the Red Sea, Sri 

 Lanka, Madras, India, Philippine Islands, and 

 Java; 2 from R. faughni from the Philippine Is- 

 lands; 13 from Scomber japonic us from the Gulf of 

 Guinea, Mauritania, and Zanzibar; 3 from S. aus- 

 tralasicus from the Philippine Islands. We have 

 reported these scombrid collections in more detail 

 in a paper describing the parasitic copepods of 

 scombrid fishes (Cressey and Cressey 1980). 



Due to the larger numbers of P. jonesi collected 

 from scombrids rather than clupeids, we consider 

 scombrids to be the preferred hosts of this copepod. 



A comparison of Bonnet's (1967) description of 

 Bomolochus jonesi and our (Cressey and Boyle 

 1973) specimens and description of Pumiliopes 

 capitulatus indicates that they are the same 

 species and that Bonnet's species clearly belongs 

 in the genus Pumiliopes. We note the following 

 differences in details of the two descriptions. 



Bennet found only four setae on each caudal 

 ramus; there are actually six, five apical (one long) 

 and one lateral. Bennet reported the first antenna 

 to be 6-segmented while we reported it to be 

 5-segmented, with the second segment relatively 

 long; the exact segmentation of this appendage is 

 often difficult to determine, but we agree on its 

 general ornamentation. The second antenna has
