Hi David and others:

The original description as given in Hartman's Catalogue is as Mediomastus 
californiensis Hartman, 1944, and this appears to have been considered 
correct in Warren, L. M., P. A. Hutchings & S. Doyle. 1994. A revision of the 
genus Mediomastus Hartman, 1944 (Polychaeta: Capitellidae). - Records of 
the Australian Museum 46 (): 227-256.  

The species treated are: Notes: Mediomastus acutus; Mediomastus 
ambiseta; Mediomastus branchiferus; Mediomastus californiensis; 
Mediomastus calliopensis n.sp.; Mediomastus capensis; Mediomastus 
caudatus; Heteromastus caudatus; Mediomastus cirripes; Mediomastus 
deductus; Heteromastus deductus; Mediomastus fragilis; Mediomastus 
glabrus;; Neomediomastus glabrus; Mediomastus setosus; Mediomastus 
thomassini  

I suspect the "californicus" is simply an overlooked typing error. The above 
information is from record 19439 of Ward & Fauchald Bibliography, 1997 
(Ulm Univ. online version).  

No references gave anything for M. californicus and 15 references, of which 
this seems the most useful (and also the most recent), gave the original 
version. A check in WebSpirs from 1993 to present gave 25 hits for M. 
californiensis and none for californicus. Judging from the reports of this 
species worldwide, it might be worthwhile taking a closer look at it. I don't 
know how much it is spread with fouling.  

Anyone else?

Mary

Greetings from Tampa,

Does anyone have information about the capitellid Mediomastus 
californiensis Hartman, 1944 being changed to Mediomastus californicus 
(Hartman, 1944) ? We are proof reading a technical report on nonindigenous 
species in Tampa Bay, and the authors list M. californicus (Hartman, 1944), 
but do not give a reference for the name change. The references that they do 
cite in the text list this species as M. californiensis Hartman, 1944. If anyone 
has any information about this, it would be greatly appreciated.   

Thank you.
