Altochara Saidakovsky, Paleontologicheskii Zhurnal 1968

Altochara Saidakovsky, Paleontologicheskii Zhurnal 1968 View in CoL (2): 103, 1968.

New synonym: Horniella Schaikin, Trudy Geologicheskogo Instituta Akademii Nauk SSSR 143: 158, 1966 (Charophyta, Characeae ), nom. illeg., non Horniella Traverse (1955: 55) , Rutaceae .

Type of Altochara : Altochara continua Saidakovsky (designated by the describing author).

Notes: Saidakovsky (1968: 103) erected the genus Altochara for Russian gyrogonites (fossilised nucules of charophytes; also a form-genus) from Triassic deposits which matched the generic description of Horniella . This was pointed out by Kisielevsky (1991), who treated both as synonyms and even used the binomial designation “ Horniella continua ” for the type species of Altochara , without effecting a transfer. Since Horniella Schaikin , typified by Gyrogonites robertsii R.E.Peck (as ‘ robertsi ’, a monotypic form genus at the time of publication), is an illegitimate junior homonym, the earliest available generic name is Altochara , and new combinations are thus required.
