Name

Melanotydaeus Berlese, 1910

• Original status: subgenus
• Gender: masculine
• Type species: Lasiotydaeus (Melanotydaeus) humeralis Berlese, 1910 by original designation (Berlese, 1910: 211)

Synonyms

• Tydeus, synonym advanced by Baker & Wharton (1952: 191). But see the notes below.

Species originally described as Melanotydaeus (example):

• Paralorryia chapultepecensis, subsequent combination used by Baker (1968: 1105)
• Pseudolorryia chapultepecensis, subsequent combination used by Kaźmierski (1989)
• Lorryia chapultepecensis, subsequent combination used by Kaźmierski (1998)
• Brachytydeus chapultepecensis, subsequent combination used by Silva et al. (2016: 12)

Notes

• Melanotydaeus was first described as a subgenus of Lasiotydaeus (Berlese, 1910a: 211) to accommodate 5 species: L. (M.) mammillaris, L. (M.) humeralis, , L. (M.) simplex, L. (M.) raphignathoides and L. (M.) styliger.
• A 6th species was added by Berlese (1910b: 346), L. (M.) venustulus, and a 7th species was added by Halbert (1920), L. (M.) brevistylus.
• It was raised to full generic level by Thor (1933: 48) and divided into two subgenera, Melanotydaeus (with humeralis and simplex) and Stylotydeus (with styliger and brevistylus).
• It was synonymized with Tydeus by Baker & Wharton (1952: 191) who misspelled the genus name (Melanotydeus instead of Melanotydaeus).
• According to Baker (1965: 102), the synonymisation must "be considered to be in error".
• Baker (1965: 99, infrapaginal note) added "The type is in such poor condition [...] and this type of structure may be an artefact".
• Baker (1965: 102) concluded that "it is impossible to know what the genus actually is".
