| Abstract |
| Mites of the family Tydeidae Kramer, 1877 (Trombidiformes: Tydeoidea) are widely distributed all over the world, with the exception of Antarctica. These soft-bodied and fast moving mites have striated and sometimes reticulated or complex idiosoma, with two prodorsal trichobothria. Species of this group present relatively short and needle-like movable cheliceral digit, fixed digit of chelicera reduced and cheliceral bases fused. They are associated with plants and inhabit several environments, such as moss, litter, straw, soil or humus, fungi, bird nests, stored food products and arboreal (on plants). These arthropods can play different important rolls in agricultural and forest ecosystems. During a sampling program in Marivan orchards (Kurdistan province, western Iran), two specimens from Tydeidae mites collected from soil under apple trees by Berlese-Tullgren funnel. These mites identified as Lorryia matura Livshitz, 1973 from soil (35° 32' 17" N, 46º 08' 35" E, H: 1289m) in 3 August 2017. This is the first record of this species from Iran. The genus Lorryia described by Oudemans in 1925 and now contain more than 200 species. Mentioned species characterizes by its dorsal "Tydeus" type of ornamentation. Dorsal side covered in most parts with striae. Reticulation limited to very front of aspidosoma and none of setae stick in reticulated cuticle. Dorsal idiosomal setae are narrowly lanceolate and serrate. Stilettos are shorter than palpal tarsi. Ventral striation is V-shaped between metasternal setae. Solenidion ω1 short and at least as long as 1/2 width of tarsus I. Empodial hooks present. Setae f1distinctly shorter than 1/2 distance f1-h1. This mite first collected and described from soil under the apple trees in Crimea. The knowledge of Lorryia mites in Iran is growing and 15 species of this genus recorded from our country so far. Much more investigations needed to complete our knowledge about their diversity and geographical distribution as well as their importance in Iranian ecosystems. |
