Diagnosis. the following diagnosis is modified from those of Aoki (1964) and Luxton (1988a). Adults: small oribatid mites (<350 μm), body with granular cerotegument; rostrum acute, rounded; lamellar cusps one-third length of lamellae, extending beyond rostrum, cusps close together medially, connected with complete or incomplete translamella; lamellar setae emerging from apex of cusp; apex rounded without teeth or pointed with two small teeth; posterior prodorsum and anterior notogaster with or without condyles of enantiophyses B; humeral processes long, broad, triangular, projecting from anterior edge of notogaster, reaching beyond bothridia, expanded at point level with dorsosejugal scissure; with eight or nine pairs of notogastral setae positioned sub-marginally. Six pairs of genital setae, two or three pairs of adanal setae; with perigenital carinae and associated enantiophysis E4. Chelicerae chelate-dentate, of normal proportions. With elongated strip of integument between median borders of epimeral plates I; pedotectum I rectangular in ventral aspect, pd II and discidium very large, rounded or pointed. Anal plate sub-rectangular, rounded anteriorly and laterally, not lozenge-shaped; pre-anal organ oval. Immatures: gastronotic setae expanded, ovoid, pointed, with fine spines, emerging from tubercles, not scale-like structures; lateral margin of prodorsum entire, not incised.

Remarks. Aoki (1964) recombined? Eutegaeus silvicola Hammer, 1962 with Neoeutegaeus and made it the type species of the genus. As well as this species and the new species described below, the genus contains N. africanus Mahunka, 1974 from Cameroon and N. phyllophorus from Australia, redescribed below.
