SCI Name: Ochthoeca leucophrys dissors
dissors
L. dissors, dissortis  not shared, of a different fate, separate, apart.
• "Myrmothera campanisona dissors, new subspecies   TYPE from the Río Cassiquiare, Venezuela, right bank, opposite El Merey.  ...  There is some variation among the adults, but the combination of characters is not duplicated in any of the other known forms."(Zimmer 1934) (subsp. Myrmothera campanisona).
• "Mr. James L. Peters has kindly called to my attention a more serious error in an earlier paper in which I made use of a pre-occupied name for a new form of Ochthoeca.  Since I discussed the earlier form, though of a different species, in the same paper, my error is inexcusable.  The necessary correction is as follows.   Ochthoeca leucophrys dissors, new name for Ochthoeca leucophrys cajamarcae ZIMMER, 1937, Amer. Mus. Novit., No. 930, p. 11 (not Ochthoeca diadema cajamarcae CARRIKER, 1934)." (Zimmer 1940) (subsp. Ochthoeca leucophrys).
• "Synallaxis rutilans dissors, new subspecies   TYPE from Campos Salles, Manaos, Brazil.  ...  Similar to S. r. amazonica from the south bank of the middle and upper Amazon, but general tone of rufescence averaging lighter, without the trace of olive on the occiput usually present in amazonica" (Zimmer 1935) (subsp. Synallaxis rutilans).
• "Tolmomyias flaviventris dissors, new subspecies   TYPE from Faro, Rio Jamundá, Brazil.  ...  The most curious fact in connection with the present form is the apparent inclusion in it of the birds from the foot of Mt. Duida, Venezuela, but the Duida birds appear to be indistinguishable from it." (Zimmer 1939) (subsp. Tolmomyias flaviventris).
• "Vireo gilvus dissors, new subspecies   TYPE from Cerro Munchique, west of Popayan, Colombia; altitude 7000 feet.  ...  Differs from V. g. leucophrys of eastern Colombia by slightly darker cap of a more grayish, less warmly hued, brown; back distinctly greener, less brownish olive; under parts not distinctive." (Zimmer 1941) (subsp. Vireo leucophrys).
