Names proposed for species-groups within genus are not considered to be
genus-group names. Article 10 (c) of the ICZN says that "a specific name
used for an aggregate of species denoted by a term such as "superspecies' is
not deemed to be a subgeneric name". In your case, the name
"forficata-group" should be also considered as a "specific name used for an
aggregate of species".
Besides, even if it were deemed to be a genus-group name,  the Article 23
(g) clearly says that "a name established expressly for a collective group
does not compete in priority with other genus-group names". Therefore, the
valid name for the genus is Forficatocaris Jakobi.
