SHORT COMMUNICATIONS P. A. A. LOOF1): A note on Paractinolaimus macrolaimus (De Man, 1880) Andrássy, 1964. Since 1913 the dorylaimid nematodes possessing a spacious buccal cavity armed with four large teeth (commonly called "onchia") have been placed in the genus Actinolaimu.r Cobb, 1913. In 1957 Meyl split up this genus, placing a number of species in new genera among which was Paractino- laimu.r Meyl, 1957, characterized by the presence of numerous denticles on the buccal walls about the level of the tips of the onchia. In 1964 Andrassy transferred Actinolaimu,r rnacrolaimu.r (De Man, 1880) Steiner, 1916 to Paractinolaimu.r, because of the presence of denticles in specimens from Africa and from Hungary. When studying De Man's nematode collection, I came across two type specimens (females) of A. macrolaimu.t. As at that time I had little experience with actinolaims and did not know Meyl's 1957 paper, I paid no special attention to the structure of the buccal walls (Loof, 1961). Re- examination of these type specimens has shown that they possess denticles characteristic of Paractino- laimu.r (see illustration). Andrdssy's transfer of A. macrolaimu.r to Paractinolaimu.r is confirmed. Fig. 1. Paractinolaimu.r macrolaimu.r (De Man) Andrissy, female.
