S. Mahunka szerk.: Folia Entomologica Hungarica 47/1-2. (Budapest, 1986)

notogaster: 204-286 um width of notogaster: 252-276 urn. Aspis (Tig. 5): Lateral carina well developed, but not arising on lateral margin (Fig. 1). Marginal line thin dwindling away. Lateral part of aspis smooth, rest of surface ornamented mostly by a weak polygonal reticulation. Basally three pairs of stronger rugae visible. All notogastral setae short, setiform, setae ro not shorter than in. Exobothridial setae reduced. Sensillus very characteristic in shape, bulbiform basally and its long distal end also lanceolate by widened (Fig.

2). Notogaster: Integument ornamented by polygonal reticulation (Fig. 3), resembling a mass of flat pustules. Fifteen pairs of short, curved notogastral setae present, their distal part slightly roughened. Anogenital region (Fig. 4): Surface of the genital and ano-adanal plates ornamented by large but weak alveoli. All setae of ano-adanal plate equal in length, straight and slightly roughened on their distal part. Material examined: Holotypus (1123-HO-85): No.P.

12, 2 paratypes: from the same sample. Holotypus and 1 paratype (1123-PO-85) deposited in the HNHM, 1 paratypes in the MHNG. Remarks: The new species is well characterized by the shape of the sensillus and the ornamentation of the notogaster. On the ground of this combination it is well distinguishable from all heretofore known Hoplophorella species. Steganacarellus gen. n. Diagnosis: Family Phthiracaridae. Habitus like that of the genus Hoplophorella Berlese, 1923. Surface of aspis, notogaster and the anogenital region well sculptured by foveolae. Fifteen pairs of dilate notogastral setae present. Nine pairs of genital and five pairs of ano-adanal setae, but adj and adg reduced, represented only by their alveoli. Setae an-j and an2 arising on the inner margin of the ano-adanal plates, all other setae far removed from it. All legs monodactylous. Types species: Stegamacarellus reductus sp.n. Remarks: The new taxon stands very near to the genus Hoplophorella Berlese, 1923, but it is distinguished from the latter and from the other well sculptured genera of the family Phthiracaridae by the reduced adanal setae. The species Hoplophorella endroedyyoungai Mahunka, 1984 (comb.nov.) belongs also to this genus. Steganacarellus reductus sp.n. Measurements. - Length of aspis: 287-386 urn, length of notogaster: 508-763 urn, height of notogaster: 336-508 um, width of notogaster: 328-492 urn. Aspis (Fig. 9): A weak, rounded median crest present. Lateral carina very weak, but visible, marginal line short. Surface well foveolate, but a region between the lateral carina and lateral margin smooth. All setae slightly dilate, ro <L le *C in, all setae spiculate (Fig. 12). Exobothridial setae long, but thin. Basal part of aspis with some longitudinal rugae. Sensillus (Fig. 8) very short, its head round. Notogaster (Fig. 6): All setae spoon-shaped (Fig. 7), but very great differences among their lengths and also among their widths, cj shorter than ps^, ps-j narrower than ps^. Tube of setae in the lateral position also of different length (Fig. 10). Lyrifissures not observable. Anogenital region (Fig. 11): Setae g-^-g^ of the genital plates slightly-, setae anj, an2 and ad

3 of anoadanal plates strongly thickened, spiniform (Fig. 12), its surface spiculate. Material examined: Holotypus: No.E.-Y. 200: 27 paratype from the same sample. Holotype and 15 paratypes deposited in the TMP, 10 paratypes (1147-PO-85) in the HNHM and 2 paratypes in the MHNG. Remarks: The new species stands near to Steganacarellus endroedyyoungai Mahunka, 1984 but setae psg and ps^ of the latter are thin and narrow, the same setae of the new species also dilate, and spoon-shaped. Nothrus mystax sp.n. Measurements. - Length: 1090 pm, width: 574 um. Prodorsum: Surface with polygonal reticulation, comprising alveoli of different sizes. All prodorsal setae thick, phylliform or spathulate (Fig. 13), lamellar setae arising on tubercles.Interlamellar setae greater than lamellar ones. Sensillus long (262 pm), longer than distance between bothridia. Its distal end smooth, other part spiculate (Fig. 14).
