A taxonomic study of the Myosoma genus-group with description of Amyosoma cavei sp. n. from Honduras (Hymenoptera: Braconidae: Braconinae: Braconini)

摘要

In 1846 Brullé described the genus Myosoma accompanied by the description of five new species. In 1900 Kriechbaumer proposed the new genus Acanthobracon on the basis of the new species A. lagopus . In 1902, 1906 and 1913 Szépligeti described six new Myosoma species, four of them originally in the genus Bracon . The current taxonomic status of the above species is discussed: some are synonymized and others remain valid. The new species: Amyosoma cavei is described from Honduras. Redescriptions are presented for nine species: Amyosoma chinense (Szépligeti, 1902), Compsobraconoides ruber (Brullé, 1846) comb. n., Myosoma brullei Szépligeti, 1906, M. errans (Szépligeti, 1902), M. fuscipenne Brullé, 1846, M. hirtipes Brullé, 1846, M. lagopus (Kriechbaumer, 1900), M. rubriventre Brullé, 1846 and Myosomatoides fasciatus (Brullé, 1846) comb. n. Acanthobracon lagopus Kriechbaumer, 1900 is revalidated and transferred into the genus Myosoma : M. lagopus (Kriechbaumer) comb. n. Four new combinations are proposed: Compsobraconoides melanocheirus (Szépligeti, 1906), C. ruber (Brullé, 1846), C. surinamensis (Szépligeti, 1906) and Myosomatoides fasciatus (Brullé, 1846) originally described in the genus Bracon by Szépligeti and in the genus Myosoma by Brullé, respectively. Six new synonyms are established: (1) Compsobraconoides ruber (Brullé, 1846) ( Myosoma ) sen. syn. = Bracon peruvianus Szépligeti, 1904 jun. syn. and Bracon rufator Szépligeti, 1906 jun. syn. (2) Myosoma fuscipenne Brullé, 1846 sen. syn. = Bracon chontalensis Cameron, 1900 jun. syn. (3) Myosoma lagopus (Kriechbaumer, 1900) ( Acanthobracon ) sen. syn. = Bracon errotus Szépligeti, 1902 jun. syn. (4) Myosomatoides fasciatus (Brullé, 1846) ( Myosoma ) sen. syn. et comb. n.; = Ipobracon pennipes Myers, 1931 jun. syn. 5.) Myosoma chinense (Szépligeti, 1902) ( Bracon ) sen. syn. = Bracon puellaris Szépligeti, 1902 jun. syn. A key is included for the Myosoma genus-group: genera Amyosoma Viereck, Myosoma Brullé and Myosomatoides Quicke as well as a key for the six Myosoma species discussed here. With 97 original figures.
