of ano-adanal setae also in typical position. The anal setae much shorter than the two pairs of posterior adanal ones. Setae ad

3 short and simple. Legs: All legs typical for the genus. Setae d on femur I bifurcate at its distal end (Fig. 8). Material examined: Holotype (1590-HO-97): Papua New Guinea, Mt. Wilhelm, 4180 m, near to peak II, with N exposition, in a warm depression, below Coprosoma divergens litter and thick moss; leg. J. Balogh; 6 paratypes: from the same sample. Holotype and 4 paratypes (1590-PO-97): deposited in the Flungarian Natural History Museum, Budapest, with identification number of the specimens in the Collection of Arachnida, 1 paratype: deposited in the Muséum d'Histoire naturelle, Genève and 1 paratype in the Collection of Dr. W. Niedbala. Remarks: The new species belongs to a species group which is characterised by the nearly equal and strong notogastral setae, the short sensillus and the length of ano-adanal setae. Among the latter setae ad

2 the longest, ad

3 the shortest, anal setae are shorter than setae ad,. It stands nearest to Notophthiracarus quietus Niedbala, 1989 and N. reptosus Niedbala, 1989, however, the new species is well distinguished from both by the form of the rostral setae (slightly dilated in the new species) and the longer and thicker lamellar setae (minute and simple in TV. quietus and N. reptosus). Etymology: We dedicate the new species to the memory of Dr. L. Gressitt, for his helping Hungarian research activity in Papua New Guinea. REFERENCES Balogh, .1.
