Remarks
. The genus
Ortalidina
Blanchard
was considered part of the
Ortalidae
(=
Ulidiidae
) when originally described, likely based on the strongly pictured wing of the
type
species, although
Blanchard (1852)
did acknowledge that this genus was somewhat different from most ortalids. Some confusion about the included species within the genus was introduced by
Steyskal (1968)
, which has been perpetuated in various online scientific-name resources. In the South American catalog of
Otitidae,
Steyskal (1968)
had a section on “Unplaced genera and species”, wherein
Dorycera conspersa
Walker
is listed first, followed by the genus
Ortalidina
(represented as a heading) with the species
cellularis
below it, then followed by seven additional species (
Ortalis decorata
Blanchard
,
Ortalis ochraspis
Wiedemann
,
Ortalis picta
Blanchard
,
Ortalis striolata
Blanchard
,
Ulidia fulvifrons
Bigot
,
Ulidia metallica
Bigot
, and
Urophora antillarum
Macquart
). Having
Ortalidina
appear as a heading had evidently confused some databasers to include the seven additional species as members of this genus. However, this would be contrary to their being in the “unplaced” category, and in the index they are listed as “unrecognized”. Additionally,
Steyskal (1968)
suggested that
Ortalidina cellularis
may be the same species as
Acrometopia australis
Malloch. Although
he did make the very astute connection of their being congeneric, they are not synonyms. Although the genus is under revision by me with several recognized new species, the key of
Cogan (1978)
and the wing photographs and various illustrations therein, as well as the photographs of primary
types
provided here, work to delimit the described species (with the exception that
Ortalidina cellularis
keys out to its synonymic species
Toropamecia grossa
Cogan
).
Interestingly, the spelling
Ortalidina
was used by
Rondani (1856)
as a family-group name based upon Fallén’s (1810) name Ortalides (based on his genus
Ortalis
); this name is currently a junior synonym of
Ulidiidae
(
Ulidiinae
: Seipterini) (
Kamaneva & Korneyev 2006
).
Following is a list of species currently recognized in the genus
Ortalidina
, including all new combinations and a new synonymy.
