FOLIA ENTOMOLOGICA HUNGARICA ROVARTANI KÖZLEMÉNYEK (SERIES NOVA) XXXII. 1. 1979 P. 15-19 Revision of the Genus Neojordensia Evans, 1957 with description of a new species from Hungary (Acari: Phytoseioidea) By M. M. KANDIL (Received December 1, 1978) Abstract : Examining the Natural History Museum mite collection, a newNeojordensid taxon was found and described. Its characters, taxonomically led to a division of the Genus Neojordensia Evans into three subgenera^ach comprising a single species: Neojordensia (Neojordensia) levis (Oudemans et Voigts) subgen. s. str., Neojordensia (Chantesia) asetosa subgen. et sp. n. and Neojordensia (Evansia) lawrencei (Evans, 1957), subgen. n. An identification key for females of the three subgenera is given. The genus Neojordensia has been established by Evans in 19 57 as to comprise a single species Neojordensia levis Oudemans et Voigts, 1904 (= Seiulus levis Oudemans et Voigts, 1904). In 1958 Evans treated Genus Neojordensia as a subgenus of Proctolaelaps s.lat. based on the type species of Oudemans and Voigts, under which he described a new species Proctolaelaps (Neojordensia) lawrencei Evans. 19 58. However, CHANT in 19 63 did not follow EVANS' s arrangement and stated that the differences between the two subgenera Proctolae laps Evans and Neojordensia Evans warrant generic separation, and described a new species Neojordensia orientális Chant, 1963. I agree with CHANT'

s opinion in considering Neojor densia Evans, 1957 as a separate genus but I believe that the new species of Chant, Neojor densia orientális Chant, 1963 is more closely related to genus Proctolaelaps Berlese, 1923, namely species Proctolaelaps ventrianalis Karg, 1971, than to genus Neojordensia Evans, 1957. In addition, I suggest that both of Neojordensia orientális Chant, 19 63 and Proctolaelap

s ventrianalis Karg, 1971, can be treated as two species of a new subgenus under genus Proctolaelaps Berlese, 1923, because of their morphologic resemblance in having elongate ventroanal shield with two pairs of preanal setae and dorsal chaetotaxic pattern. Also by examining the present Hungarian material represented by Proctolaelap

s (Neojordensia) levis Oudemans et Voigts and a new species (description see below), it could be distinguished that Neojordensia Evans differs significantly from Proctolaelaps Evans by the following characters: 1. Neojordensia species have a large strongly sclerotized ventroanal shield having four pairs of preanal setae, whereas Proctolaelaps species with an anal plate, except Procto laelaps ventrianalis Karg, 1971, which has an elongate ventroanal shield with a weak sclerotization, and only two pairs of preanal setae resembling that of Neojordensia orientális Chant, 1963. 2. The eight transverse Q lines which are usually found on ventromedian part of hypostome, appear to be limited by the two longitudinal lines and each consisting of only two denticules
