This is the second part of a study of a large collection of Siphonophoridae Cook, 1895 from
Brazil. Here, those without an abrupt division between the head and rostrum are considered. Two species
have been distinguished and are described as
Siphonophora setaepromissa
sp. nov. and
S. tuberculata
sp. nov.
Siphonophora hebetunguis
(Attems, 1951) from the same region has many similarities
with the two new species and is redescribed from type material. Comparisons have also been made
with
S. fuhrmanni
Carl, 1914, and comments are made on the genera
Cordillerium
Verhoeff, 1941,
Pterozonium
Attems, 1951,
Rhinosiphora
Verhoeff, 1924, and
Siphonophora
Brandt, 1837. Finally,
some suggestions for characters to look at in future collections of siphonophorids are made based on
experience of this collection.
