Remarks.
This species was described by
Fraser (1936c)
based on material sent to him on behalf of Emperor Hirohito.
No
name-bearing
types
were originally designated but the
type
series includes material in the Fraser Hydroid Collection at the RBCM (BCPM 976-00291-001; BCPM 976-00292-001; BCPM 976-00293-001; BCPM 976-00293-002). Specimens in IPA (BCPM 976-00291-001; BCPM 976-00292-001) appear to have been dry sometime in the past and are now in poor condition. The best specimen in the
syntype
series, on a slide (BCPM 976-00293-001), is designated here as the
lectotype
. Although collection data accompanying the slide are incomplete, the specimen is known to have been collected in Sagami Bay and is almost certainly a fragment taken from one of the fluid collections as the species was being described.
Twelve lots of hydroids identified as
Egmundella humilis
, also collected from the type locality in advance of Fraser’s description of the species, exist in the Emperor Shōwa Hydroid Collection at the NMNS (NSMT-HyR 940–NSMT-HyR 951). We do not know whether Fraser examined any of these specimens, and we excluded them from the syntype series.
Specimens examined by
Fraser (1936c)
were said to be infertile. Although gonothecae are present on the two slides, it is uncertain that they are those of
E. humilis
because a clytiid is also present on the slide. In any case, the gonosome of the species was observed and described later by
Hirohito (1995)
. Gonothecae described by him appeared to contain developing medusae.
Egmundella humilis
is listed as valid in WoRMS.
Galea (2013)
included
E. modesta
Millard & Bouillon, 1975
from the
Seychelles
as a questionable synonym of this species.
