Remarks. This new species closely resembles Cheylostigmaeus pannonicus Willmann by setae m located on one pair of bicuspidate lamellae. However, it differs from the latter by: ratio sce: sci = 1.4 [sce 110 (105–125), sci 77 (65–97)] in female of the new species versus 1.1 (sce 75 + 4, sci 67 + 4) in the U.S.A. specimens (Summers & Ehara 1965); the distance of e 1 - e 1 [125 (123–130)] is subequal that of d 1 - d 1 [123 (120–127)] in female of the new species but d 1 - d 1 (122 + 11) is longer than that of e 1 - e 1 (110 + 7) in the U.S.A. specimens (Summers & Ehara 1965); the lateral rostral lamellae of both original and redescribed males of C. pannonicus are much larger than those in the new species (Willmann 1951; Summers & Ehara 1965); in all specimens of C. pannonicus apophyses on the palp femur are absent (Willmann 1951; Summers 1957 a; Summers & Ehara 1965) whereas the new species has apophyses on the palp femur.
