ber]
Reference: \/em/s, 4(3): 186
Type genus: Pseudosacculus Hirase, 1928
Remarks: Implicitly, but not explicitly, established
as a replacement name for Saccul-
idae, invalid because its type genus is a
junior homonym, -idae, Wenz (1938 [in
1938-1944]: 47; 1940 [ibid.]: 957).

idoptera].
PsEUDOTHECosoMATA Meisenhelmor, 1905 [22
January]
Reference: Deutsche Tiefsee Expedition, 9(1 ):
4,174
Remarks: Taxon containing the families Cym-
buliidae and Desmopteridae, established at
unspecified rank above family. Treated by
Thiele (1926 [in 1925-1926]: 108) as a
"Sippe" [= superfamily] and not available as
such (not based on a genus).

April]
Reference: Bullettino delta Société Maiacologica
italiana, 1(1): 19
Type genus: -fPseudotomaA. Bellardi, 1875
Remarks: Pseudotoma Bellardi, 1875, is listed
in Nomenclátor Zoologicus as a junior
homonym of Pseudotoma Gray, 1 825 [Mam-
malia]. However, Gray merely used an incorrect
subsequent spelling of Pseudostoma
Say, 1823, and "Pseudotoma Gray, 1825",
is not an available name.

Type genus: Pseudoveronicella Germain,
1908
Remarks: Established as a replacement name
for Meisenheimehinae, presumably because
Pseudoveronicella is the oldest name among
the nominal genera included by Hoffmann
in the subfamily. However, he did not treat
Pseudoveronicella and Meisenheimeria as
synonyms, and Art. 40.2 does not apply.

"Sippe" [superfamily, containing Janthinidae,
Scalidae and Aclididae]. Not available as a
family-group name (not based on a genus).
