Material examined: Holotypus (1124-HO-85): No.P.

72; 2 paratypes from the same sample. Holotypus and 1 paratype (1124-PO-85) deposited in the HNHM and 1 paratype in the MHNG. Remarks: The "

palustris

" group of the genus Nothrus C.L.Koch, 1836 was discussed by MAHUNKA (1978). The new species is well characterized by the tridactylous legs, the long sensillus and the more than four times long difference between setae kj and ps^. On this ground it stands close to N. espinarensis Beck, 1962, however the sensillus of the latter is shorter and also the ratio of the notogastral setae is a good distinguishing character. Trichonothrus gen.n. Diagnosis: Family Nothridae. Rostrum without median incision. Sensillus flagellate. Sixteen pairs of notogastral setae present. Epimeral setal formula: (15-16)-(5-6)-8-7. Anogenital setal formula: 9-0-2-3. Genital setae dispersed on the whole surface of genital plates. All legs tridactylous. Figs 11-12. Steganacarellus reductus sp.n. - 11: anogenital region, 12: interlamellar setae
