| Summary: | Genus Sierraphytoptus Keifer, 1939: 151 Sierraphytoptus Keifer, 1939: 151, fig. LI; 1965: 8, fig. 4; Newkirk, Keifer 1975: 567; Amrine et al., 2003: 17, fig. 18. Fragariocoptes Roivainen, 1951: 51 [Synonymy by Roivainen (1953, p. 85)]; Farkas, 1965: 8 Type species: Sierraphytoptus alnivagrans Keifer, 1939, by monotypy. Diagnosis: opisthosoma diversely annulated; prodorsal shield with four setae – ve and sc; a pair of setae c 1 on the dorsal part of opisthosoma; solenidion on leg I, II missing. Species included: Sierraphytopyus alnivagrans Keifer, 1939, S. ambulans sp. n., S. setiger (Nalepa, 1894) Distribution and hosts. Mites of the genus are recorded from North America, Asia (Armenia, Ural region and South Siberia of Russia, China) and Europe. Host-plants of these mites include dicots from the orders Fagales (Alnus spp.) and Rosales (Fragaria spp.). Remarks. The species S. taiwanensus from T. aralioides is removed from the genus because it possesses a solenidion on tibia I, while in Sierraphytoptus it is missing. The tibial solenidion was not measured and figured in the description of S. taiwanensus given by K.W. Huang (2006), but the female (slide # 030416 -01, Taiwan, Nantou Ren-ai 2003 /04/ 16, coll. K.W. Huang) and nymph (slide # 961031 - 17, Taiwan, Taichung Anmashan, 1996 / 10 / 31, coll. C.F. Wang) of this mite do have a tibial solenidion (Fig. 1). Therefore, the morphological features of S. taiwanensus correspond to the diagnosis of the genus Austracus Keifer, 1944 and we transfer it to this genus: Austracus taiwanensus (K.- W. Huang 2006) comb. n. Mites of the genus Sierraphytoptus were first found by А. Nalepa (1894) inside red galls on leaves of F. viridis and described under the name Phyllocoptes setiger (Table 1). Later, Liro (1941) found similar mites on F. vesca in Finland. He identified them as P. s e t i g e r and suggested that there were two subspecies, which remained unnamed: one formed red galls on leaves of F. viridis and lived inside them, but the other lived on the lower surface of ... |
