Tribe Blenniini (type-genus Blennius Linnaeus) : Interopercle with- 

 out postero ventral spur; pterosphenoid visible when skull is viewed 

 laterally; dorsal fin with or without a notch between spinous and 

 rayed portions; dorsal fin rays 13-24; last anal pterygiophore sup- 

 porting a single ray; pelvic rays 1,3-1,4; 6-10 branched rays in caudal 

 fin (except all rays simple in Medusablennius chani); gUl opening usu- 

 ally extending ventrally to or below level of midbase of pectoral; 

 premaxillaries and dentaries strong, not excavated; bases of comblike 

 teeth of dentaries and premaxillaries joined closely and tightly to 

 bone; replacement teeth developing internally in hollow of each pre- 

 maxillary and dentary (developing replacement teeth completely sur- 

 rounded by bone of jaws); posterior canines present or absent on 

 dentaries and premaxillaries, enlarged or normal relative to comblike 

 teeth; teeth on premaxillaries fewer than 60; ascending process of 

 premaxillary weakly to strongly based on body of premaxillary; 

 dentaries united by even, nonsutiu-ing joint (except Blennius ocellaris 

 and B. normani), circumorbitals 5 (2 in Medusablennius chani); supra- 

 cleithrum with or without tube for sensory canal. 



Tribe Omobranchini, new tribe (type-genus: Omohranchus Ehren- 

 burg): Interopercle with ventroposterior spur extending posteriorly 

 beyond posterior margin of epihyal; pterosphenoid not visible when 

 skull is viewed laterally; dorsal fin without a notch between spinous 

 and rayed portions; dorsal fin rays 17-26; last anal pterygiophore sup- 

 porting a single ray; pelvic rays 1,2; caudal rays unbranched (rare 

 individuals with 1 or 2 rays branched) ; gill opening usually restricted 

 to area above level of dorsalmost pectoral ray base; premaxillaries 

 and dentaries strong, not excavated; bases of comblike teeth of pre- 

 maxillaries and dentaries joined closely and tightly to bone; replace- 

 ment teeth developing internally in hollow of premaxillaries and den- 

 taries (developing replacement teeth completely surrounded by bone 

 of jaws) ; posterior canines present on dentaries and premaxillaries 

 (except adult females of Omohranchus herklotsi), enlarged relative to 

 comblike teeth; teeth on premaxillaries fewer than 40; ascending proc- 

 ess of premaxillary strongly based on body of premaxillary; dentaries 

 imited by suturing joint; circumorbitals 3-5; supracleithrum without 

 tube for sensory canal. 



Tribe Salariini (type-genus Salarias Cuvier): Interopercle without 

 ventroposterior spur; pterosphenoid visible when skull is viewed later- 

 ally; dorsal fin with or without a notch between spinous and rayed 

 portions; dorsal fin rays 10-24; last anal pterygiophore supporting 

 1 or 2 rays; pelvic rays 1,2-1,4 (most genera 1,3 or 1,4); caudal rays 

 branched or unbranched (branched in most genera); gUl opening 

 extending ventrally to below level of ventral pectoral base; premaxil- 

 laries and dentaries weak to moderately strong; one or both moderately
