Remarks.
Neither the
holotype
nor any other specimen of
Cimbrochrysa moleriensis
is found in any museum (FM, NHMD). Therefore, the description of
Schlüter (1982)
is the only information for the species.
Rust (1999)
assigned a forewing (MM 5-B2388) to it; however, the
holotype
and that specimen are surely not conspecific, as crossvein 2m-cu is located in the basal half of the intramedian cell in MM 5-B2388, as mentioned by
Rust (1999)
, but this crossvein is located nearly in its middle in all other known Fur species of
Nothochrysinae
, including
C. moleriensis
(2m-cu is located the proximal half of the intramedian cell in the right forewing of the
holotype
of
D. madseni
, but it is shifted distally in the left wing). Based on the proximal location of 2m-cu, MM 5-B2388 might belong to a genus similar to one of the North American genera,
e.g
.,
Palaeochrysa
Scudder, 1883
,
Lithochrysa
Carperter, 1935
or
Archaeochrysa
Adams, 1967
. Unfortunately,
Rust (1999)
did not provide a photograph of MM 5-B2388.
