r Ventral side (Fig. 10). Apodemes thin both on anterior and posterior sternal plates, in fact, very weakly developed, ap. 4 short, scarcely reaching beyond base of hair 3b. Epimeres 4 bearing only two pairs of hairs 4a missing. Legs. Tibiotarsus of leg I (Fig. 11) elongate, spindle-shaped, pointed in front, solenidion uj j not reaching apex of joint. Shape and chaetotaxy of leg IV are depicted in Fig. 12. Material examined. Holotypus: USA, Syracuse, NY, 8. 12. 1973 and 10. 15. 1973, from owl pellet, leg. J.R. Philips. 1 paratype from same locality as holotype. The holotype is deposited in the coUection of the coHector, the paratype (358-PT-77) in the Hungarian Natural History Musem, Budapest. Remarks. The new species belongs to the allies of Brennandania silvestre (Jacot, 1936) since this one too is missing hairs 4a from epimere 4. Nevertheless, the proportions of the hairs on the hysterosoma widely differ from B. silvestre as well as from all known congeners. Furthermore, it may readily be separated also by its particularly long hairs h. We dedicate this new species in honour of the late, great American acarologist Dr. A. P. JACOT. SCU TAC ARID AE Pygmodispus (Pygmodispus) abestus sp. n. Measurements. Length: 172 u, breadth: 128 u. Habitus. Rounded in front and behind by the same arc, thus, it is regular ellipsis in outRne. Dorsal side (Fig. 13). Clypeal margin broad, all hairs similarly to dorsal ones thin and short. Segment H bearing three pairs of hairs. Ventral side (Fig. 14). Apodemes of anterior sternal plate thick, heavily chitinized. ap. 2 strikingly robust. Posterior sternal plate somewhat weakly chitinized, apodeme 4 short and thin. Frontal corners of plate enlarged with backward projecting, curving spurs. Epimereal hairs simple, 2b scarcely thicker than others. Epimeres 3 with hair distance between hairs 3a smaller than same between 3a and 3b. Hairs 3b emitted further from frontal margin of plate than either 3a or 3c. Hairs 4a originating between pair of 4b, reaching in between insertion points of hairs 4b. Legs. Tibiotarsus (Fig. 15) of leg I without a claw, at most a short peg is perceptible at its place. Tarsi of legs II and III with thick hairs ld^' and ld^

J that are somewhat ciRate. Trochanter of leg IV (Fig. 17) ending beneath in a sharp, bent apex. Material examined. Holotypus: USA, Syracuse, NY, owl pellet, 11.8.1973, leg. J.R. Philips. The holotype is deposited in the collection of the collector. Remarks. The species is well described by the lack of claw on leg I and the shape of the trochanter of leg IV. The genus Pygmodispus PaoR, 1911 included so far two species which lacked the claw on leg I. One of these: P.mancus Mahunka, 1967 belonged in the subgenus Allodispus PaoR, 1911, while the other into the nominate subgenus (P. crenatus Mahunka, 19 67). Thus, the new species closest to the latter species but differs from it by the much longer hairs on epimeres 3 and 4, as well as by the larger spur on the trochanter of leg IV. Scutacarus ameropannonicus sp. n. Measurements. Length: 178 u, breadth: 142 p.. Habitus. Clypeus only scarcely wider than segment D; body obovoid in outRne. Dorsal side (Fig. 18). Clypeal margin broad, both pairs of clypeal hairs with strong ciRa, similar are hairs d^, e^ and f-^. Hairs e
