ON THE SPECIES STATUS OF PARATRICHODORUS ALLIUS (JENSEN, 1963) AND P. TANSANIENSIS SIDDIQI, 1974 (NEMATODA, TRICHODORIDAE) BY DIETER STURHAN Biologische Bundcsanstalt für Land- und Forstwirtschaft, Institut fiir Nematologie und Wirbeltierkunde, Toppheideweg 88, D-4400 Münster, Federal Republic of Germany A comparison of P. allius and P. tansaniensis populations of different geographical origin has shown that the two species cannot be differentiated by morphometrical and other morphological characters. P. tansaniensis is thus synonymized with P. allius. Only populations from Italy dif- fered in certain characters from the other populations studied. Keywords: Taxonomy, morphology, descriptions. Among the 23 Paratrichodorus species recognized today, P. tansaniensis Sid- diqi, 1974 most closely resembles P. allius (Jenscn, 1963) Siddiqi, 1974. P. allius was originally described from Oregon and apparently subsequently recorded only from three additional states of the USA (Norton, 1984). P. tansa- niensis, described from 'Tanzania and also found in South Africa (Vermeulen & Heyns, 1983), was reported by Roca & Lambcrti (1984) from Italy. P. tansaniensis was differentiated from P. allius by Siddiqi (1974) "in having a shorter body and spear, a relatively more anteriorly situated excretory pore and differently shaped vaginal mass and sclerotization".
