Sychnotylenchus mutici Massey, 1974 from the Slovak Republic

Selected morphometrics with diagnostic value for Sychnotylenchus spp. (excretory pore location, quadricolumella, vulva and anus position, male presence and its terminal body features, etc.), are presented here from a bisexual Sychnotylenchus sp. The specimens of nematodes used in this study have been observed and recovered from beetle galleries of dead Carpinus betulus L. in trees in Carpineto-Fagetum forest type in the locality of Trebejov near the city of Kosice in the eastern region of Slovakia. The nematode species has been identified as S. mutici. The species was originally described in the USA by Massey (1974). It is the first report of this species in Europe, thus expanding the borders of its geographical distribution.
