Geographic distributions of E. hyalinuss.s. and E. spinifer.
Solid black circles correspond to E. hyalinus s.s., open circles to E. spinifer, and grey circles to plankton tows in which the species co-occurred. Neotype specimens marked by + and x, respectively.
Original distribution of E. hyalinus largo sensu outlined, after Fleminger & Hulsemann (1973). |
