Thamnistes rufescens Cabanis

Thamnistes rufescens Cabanis, 1873a: 65 .

Now: Thamnistes anabatinus rufescens Cabanis, 1873 . See Cory & Hellmayr (1924: 113).

Type series: Cabanis (1873a: 65) based this species on an unspecified number of specimens, which included at least a male and a female. Taczanowski (1875: 530) listed only a single specimen of each sex. The type series of Thamnistes rufescens Cabanis thus consisted of two syntypes, both of which were deposited in the MIZ ( Taczanowski 1889: 20) and were destroyed in the 1920s (cf. Sztolcman & Domaniewski 1927: 120–121; see Mlíkovský 2009b for details).

Syntype (lost): MIZ unnumbered (N.7152), 3, collected by Jelski on an unknown date [= October 1871 to February 1872] at "Amable-Maria" [= Amable María, Peru].

Syntype (lost): MIZ unnumbered (N.7152), Ƥ, collected by Jelski on an unknown date [= August to December 1870] at "Monterico" [= Monterrico, Peru].

Type locality: "Monterico" according to Cabanis (1873a: 65), who believed that both syntypes were collected there, but Taczanowski (1875: 530) wrote that the syntypical male was collected at "Amable-Maria", and the syntypical female at "Monterico". Sztolcman & Domaniewski (1927: 120–121) selected "Amable Maria" as terra typica of the species, because the male was collected there, albeit without designating the male as a lectotype of the species. Their action is thus invalid (see ICZN 1999, Art. 76) and the type locality of Thamnistes rufescens Cabanis continues to comprise both localities where the syntypes were collected, i.e. Amable María [11.17°S, 75.35°W] and Monterrico, Peru [12.05°S, 74.10°W].

Remarks: The ZMB received in June 1873 (see the Accession Catalogue sub Nr. 10226) a male of Thamnistes rufescens (ZMB 21190) collected by Jelski on an unknown date at ”Monterico”. It has no type status, because Cabanis (1873a) presented the description of this species at the 5th Annual Meeting of the German Ornithological' Society held in Berlin on 10 October 1872, prior to receipt of this specimen, and both syntypes were later deposited in the MIZ (see above). However, this is a topotype, which probably originated from the same series as the lost syntypes did.
