On two generic homonymies in Cerambycidae (Coleoptera)

Abstract

Micropsalis Burmeister, 1861 (Prioninae) is preoccupied by Micropsalis Meyer, 1859 (Crustacea). Thus, Apterocaulus Fairmaire, 1864, currently synonym of Micropsalis Burmeister, is reinstated. A historical review about Apterocaulus and Micropsalis Burmeister is added. Microcometes Villiers, 1959 (Disteniinae) is a junior homonym of Microcometes Cienkowsky, 1875 (Protozoa), and Villiersicometes is proposed to replace it.

ABSTRACT

Micropsalis Burmeister, 1861 (Prioninae) is preoccupied by Micropsalis Meyer, 1859 (Crustacea). Thus, Apterocaulus Fairmaire, 1864, currently synonym of Micropsalis Burmeister, is reinstated. A historical review about Apterocaulus and Micropsalis Burmeister is added. Microcometes Villiers, 1959 (Disteniinae) is a junior homonym of Microcometes Cienkowsky, 1875 (Protozoa), and Villiersicometes is proposed to replace it.

Key words:Apterocaulus, Microcometes, Micropsalis, Villiersicometes.

The study of the Prioninae and Disteniinae (Cerambycidae), during the identification of the specimens of the MZSP (Museu de Zoologia, Universidade de São Paulo) and other institutions, revealed two new homonymies.

Apterocaulus Fairmaire, 1864, gen. rev.

Micropsalis Burmeister, 1861: 314; 1865: 157 (preocc. Meyer, 1859 – Crustacea); Lacordaire, 1869: 43; Monné & Giesbert, 1994:14 (cat.); Monné, 1995: 61 (cat.).

Apterocaulus Fairmaire, 1864: 267; Thomson, 1864: 496; Burmeister, 1879: 196; Lameere, 1912: 175.

Psalidognathus(Apterocaulus); Lameere, 1913: 66 (cat.); 1919: 121; Porter, 1933: 207; Blackwelder, 1946: 555 (cat.).

Psalidognathus(Micropsalis); Lameere, 1910: 378.

Type species. Apterocaulus germainii Fairmaire, 1864 [ = Apterocaulus heterogama (Burmeister, 1861)], herein designated.

Included species. Apterocaulus heterogama (Burmeister, 1861) comb. nov.

Micropsalis Burmeister, 1861 (Prioninae, Prionini) is homonym of Micropsalis Meyer, 1859, an available generic name in Crustacea, established for M. papyracea Meyer, 1859 (fossil). Herein, Apterocaulus Fairmaire, 1864, currently under synonymy of Micropsalis Burmeister (MONNÉ 1995), is reinstated.

BURMEISTER (1861) erected the genus Micropsalis based on M. heterogama, from Argentina. FAIRMAIRE (1864) established Apterocaulus for A. germainii and A. marginipennis, both from Argentina. LACORDAIRE (1869) synonymized Apterocaulus under Micropsalis, A. germainii with M. heterogama and, A. marginipennis with M. servillei (Blanchard, 1851), originally described in Ancistrotus Audinet-Serville, 1832. THOMSON (1877) established the genus Acalodegma for A. servillei ( = M. servillei).

BURMEISTER (1879) described Micropsalis durnfordii, also from Argentina and, according to LACORDAIRE (1869), mentioned in this genus, M. heterogama and M. servillei, apparently ignoring THOMSON (1877).

LAMEERE (1910) considered Micropsalis as a subgenus of Psalidognathus Gray, 1831, and synonymized M. durnfordi (sic) under P. (Micropsalis) heterogama. LAMEERE (1912) stated: "Psalidognathus Germaini Fairm. – C'est le nom que doit porter le P. heterogama, et le sous-genre Micropsalis doit prende la dénomination d'Apterocaulus Fairm. La description de l'Apterocaulus Germaini Fairm. a, en effet, paru avant celle du Micropsalis heterogama Burm., l'ouvrage de Burmeister, Reise la Plata, étant antidaté". LAMEERE (1913) catalogued the species as Psalidognathus (Apterocaulus) germaini var. Durnfordi (sic).

BOSQ (1953) in his retrospective of Apterocaulus, kept it as a subgenus of Psalidognathus and raised the variety durnfordi (sic) to subspecies [P. (A.) germaini durnfordi (sic)]. BOSQ (1853) did not consider the BURMEISTER'S (1861) description of Micropsalis, regarding the original description as that of BURMEISTER (1865), according to LAMEERE (1912).

MONNÉ & GIESBERT (1994) reinstated Micropsalis heterogama, considering Apterocaulus as synonym of Micropsalis Burmeister and, A. germainei (sic) and M. durnfordii as synonyms of M. heterogama. MONNÉ (1995) kept M. durnfordii under synonymy and stated about Apterocaulus: "Type species, Apterocaulus germainii Fairmaire, 1864, monotypy". However, based on data above, FAIRMAIRE (1864) erected Apterocaulus for two species: A. germainii and A. marginipennis. This way, the type species was never designated for the genus.

DI IORIO (1996) wrote about the biology of Psalidognathus germaini durnfordi (sic), without justifying the reinstatement of the species and of the subspecies, and generic transfers.

Apterocaulus germainii is synonym of A. heterogama. In relation to Apterocaulus and Psalidognathus, they have distinctive characters allowing to maintain both as different genera following the proposition of MONNÉ & GIESBERT (1994) (through Micropsalis Burmeister). Among the diagnostic characters, the most notable are the shapes of the mandibles and metasternum [see LACORDAIRE 1869: 37 (key); LAMEERE 1910: 378]. No specimens of A. heterogama durnfordii were examined and the considerations about this subspecies name could not be evaluated.

Villiersicometes nom. nov.

Microcometes Villiers, 1957: 410; 1980: 29; Monné & Giesbert, 1994: 302 (cat.) (preocc. Cienkowski, 1875 – Protozoa).

Etimology. In honour to André Villiers, by his valuable contributions towards the knowledge of the Disteniinae of the world.

Type species. Cometes wagneri Gounelle, 1911, designated by VILLIERS (1957) for Microcometes.

Included species. Villiersicometes bijubatus (Gounelle, 1911) comb. nov.; V. lineatus (Villiers, 1957) comb. nov.; V. wagneri (Gounelle, 1911) comb. nov.

Microcometes Villiers, 1957 (Disteniinae, Disteniini) is homonym of Microcometes Cienkowski, 1875 (Protozoa). CIENKOWSKI (1875) established the genus to M. paludosa [incertae sedis, according to PATTERSON (1999) and personal communication], but the publication date is controversial: 1875 [e.g. Zoological RECORDS (1877)] or 1876 [e.g. NEAVE (1940)]. Herein, Villiersicometes nom. nov., is proposed to replace Villiers' homonym.
