Three new species of the genus Favognathus Luxton (Acari: Cryptognathidae) and re-description of Cryptognathus lagena Kramer from Iran

Three new species of the genus Favognathus Luxton, 1973 are described from Iran, namely Favognathus esfahaniensis sp. nov., collected from soil under lichen at Najaf Abad, Esfahan Province; Favognathus alvandii sp. nov., from soil under plum, hawthorn and quince trees at Hamedan, Hamedan Province; and Favognathus guilanicus sp. nov., from soil under an unknown plant at Rasht, Guilan Province. The female and male of the type species Cryptognathus lagena Kramer, 1879 are re-described. Cryptognathus sternalis Krantz, 1958 is removed from synonymy with C. lagena after examination of the ornamentation and leg setation of type specimens, because trochanter I has 1 seta and tarsi I-IV 15(1 omega)-12(1 omega)-9(1 omega)-9 (1 omega) in C. lagena instead of trochanter I nude and tarsi I-IV 15(2 omega)-12(2 omega)-10(1 omega)-10(1 omega) in C. sternalis.
