Abstract: The paper discusses some doubts concerning the taxonomic rank of Thrips atratus Haliday, 1836 and Thrips montanus Priesner, 1920 (T. atratus f. montana according to zur Strassen 2003). For these purposes morphological characters of adults and second stage larva of some populations coming from various regions of Poland were compared. They were studied using cluster analysis and principal component analysis for selecting the significant features separately for females and males. For adults the differences most useful for taxa separation include previously described features, such as the colour of the third antennal segment, the number of distal setae on the first vein of the forewing (for females and males) and new features: the shape of the microtrichial comb on the posterior margin of tergum VIII, and the number of discal setae on abdominal sterna V and VII (females); the length of antennal stylus, the sculpture of the tenth sternum, and the width of pore plates on abdominal sterna V and VII (males). For larvae, the main differences pertain to the number and fusion of sclerotized plates on the pronotum, the degree of developing microtrichia on plaques of tergum and sternum VIII and the differences in sclerotisation of abdominal terga IX and X. The earlier known and the new morphological characteristics of females, males and larvae supported by statistic analyses lead us to believe that the previous taxonomic status – as separate species (T. atratus Haliday and T. montanus Priesner) was correct.
