– The species is named in honour of Árpád (850–907), Reigning Prince of the seven Hungarian tribes. O THER MATERIAL –. R EMARKS – The foretibia seemingly two-segmented: a short and thick basal part with tibial seta, and a longer and thin distal part. The new species is similar in morphology to R. cerritaurus Livshitz, Mitrofanov et Vasilyeva, from which it differs in the number of empodial rayes (9), the pattern of shield, the shape of anteromedian lobe (broad and blunt) also length of opisthosomal setae d, e and f (Livshitz et al., 1979).
97 Fig. 5. Rhyncaphytoptus arpadi n. sp. – semischematic drawings Aceria magyarica n. sp. D IAGNOSIS – prodorsal shield pattern composed of a light median and two admedian lines. Empodium 3-rayed, coxae with granules; sparsely microtuberculate semiannuli be- tween coxae and genital region. F EMALE (Fig. 6) – Body wormlike, 228 (222–233, n = 9), 46 (44–46) thick. Gnatho- soma 21 (20–21), projecting obliquely downwards; chelicerae 18 (18–20), seta d 7 (5–7). Prodorsal shield 26 (25–26), 25 (22–25) wide, semielliptical anteriorly, without anterome- dian lobe over gnathosomal base; shield pattern composed of a light median and two ad- median lines. Tubercles sc on rear shield margin, 15 (15–16) apart, setae sc 14 (12–14), directed to the rear, diverging. Foreleg 40 (36–42), tibia 4 (4–5), tarsus 6 (5–6), ~ 7 (6–7), with small knob, em- podium simple, 3-rayed. Hindleg 37 (35–40), tibia 4 (4–5), tarsus 5 (4–5), ~ 10 (8–10), with small knob, empodium simple, 3-rayed.

(Fam. Fagaceae). R ELATION TO THE HOST – the whitish mites were found on the acorn. No apparent dam- age was observed. T YPE LOCALITY – Budapest, district XII, Széchenyi-hegy, Széchenyi-emlék street, 425 m elev.; 47°29.641’N, 18°59.268’E. T YPE MATERIAL – Holotype female circled with black ink among 6 females and 1 male on one slide, 28 July 1999, slide # 1029Mc; Paratypes – 1 slide (# 1029Ma) prepared from material collected in the same locality on the same date, containing 3 females, 2 males and 1 nymph; coll. G. Ripka. E TYMOLOGY
– The specific designation is derived from the name of Magyar = Hun- garian, Latinized with -ca. O THER MATERIAL –. R EMARKS – The new species is similar in morphology to Aceria quercinus (Canestrini), from which it differs in the shield pattern and the number of striae (6) on fe- male genital coverflap (Canestrini, 1892).
