Remarks.

Melzer (1934) described A. bruchi based on two specimens from Argentina (Chaco and Misiones). According to him (translated): “ Type at the collection of Mr. C. Bruch; cotype at my collection. ” The private collection of Carlos Bruch is current at the Museum Argentino de Ciencias Naturales “ Bernardino Rivadavia, ” and the private collection of Julius Melzer is currently deposited at MZSP. However, the paratype (cotype) is not present at MZSP. According to Monné (2023) and Tavakilian and Chevillotte (2023) the holotype is the specimen from Argentinean province of Chaco. However, Melzer (1934) did not provide this information. Therefore, as the paratype was not found, only the examination of the labels of the holotype may provide this information. Although Melzer (1934) did not inform the sex of the two specimens in the text of the description, at least one of them, the specimen illustrated, is a male; this information is present in the legend of the figure: “ Alcidion Bruchi n. sp. [symbol of male]. ” Tavakilian and Chevillotte (2023) record the work in which Julius Melzer described Alcidion bruchi as having been published in 1935. However, there is no evidence of this in the magazine. Therefore, the correct year, which appears in the magazine, is 1934.
