Acari malaconothrid mites taxonomy recombination synonymy


Three Egyptian species of the oribatid mite family Malaconothridae, all found on roots of the floating aquatic plant Eichhornia crassipes in the River Nile, are analyzed. Trimalaconothrus crassipes Ramadan, Ismail & Mustafa, 2017 is recombined to Tyrphonothrus crassipes (Ramadan, Ismail & Mustafa, 2017) (comb. nov.). Malaconothrus ramadani Ramadan, Ismail & Mustafa, 2018 and M. transversus Ramadan, Ismail & Mustafa, 2018 are both considered to be tritonymphs of Ty. crassipes (=M. ramadani syn. nov.; =M. transversus syn. nov.).
