PIETSCH and SEIGEL: CERATIOID ANGLERFISHES OF THE PHILIPPINE ARCHIPELAGO 



Distribution. — Oneirodes sabex is known only 

 from southeast Asian and eastern Australian 

 waters: the Alpha Helix material, including the 

 holotype and 10 paratypes, was collected in the 

 Banda Sea; the 121 mm SL paratype (SIO 70-339) 

 is from off Luzon, Philippines; the 32.5 and 39 mm 

 SL paratypes (AMS L 20315-010, AMS L20314- 

 016) were collected off Sydney, Australia. 



Etymology. — The name sabex is an acronym 

 formed from the initial letters of the name "South- 

 east Asian Bioluminescence Expedition" in recog- 

 nition of the important ichthyological contribu- 

 tion made by those involved. 



Oneirodes schistonema n. sp. , Figures 11, 12; Table 2 



Material. — A single female, the holotype, LACM 

 36036-3, 74 mm, stn 24. 



Diagnosis. — A species of Oneirodes differing from 

 all previously described species in escal morphol- 



ogy: anterior appendage branched, unpigmented 

 internally; medial and anterolateral appendages 

 absent; posterior appendage branched. 



Description. — Escal appendage pattern B (Pietsch 

 1974a, fig. 60B); esca with a stout, unpigmented, 

 anterior appendage, less than length of escal bulb, 

 bearing four, short, distal branches; pigmented 

 internal tube of anterior appendage absent; me- 

 dial and anterolateral appendages absent; termi- 

 nal papilla without distal pigment spot; posterior 

 appendage as large as anterior appendage, bear- 

 ing four short branches near distal end (Figure 

 11). 



Upper end of suboperculum long, narrow, and 

 tapering, left suboperculum deeply indented (Fig- 

 ure 12); length of lower fork of operculum 25. 3^^ of 

 SL; ratio of lengths of upper and lower forks of 

 operculum 0.48. 



Epibranchial teeth absent; teeth present on 

 pharyngobranchial IL 



Counts and measurements in Table 2. 



Etymology . — The name schistonema is derived 

 from the Greek schistos, meaning divided, and 

 nema, thread, alluding to the divided anterior and 

 posterior escal appendages of this species.

 cruise 7, stn 13N, Bermuda, lat. 32°18' N, long.
