SUMMARY The family Anguinidae is redefined ; it includes the genera Scopoli, 1777 ; Nofhanguincz Whitehead, 1959 ; Afrinn g. 11. ; Orrina g. n. ; Subunguina Paramonov, 1968 ; Difylenchzzs Filipjev, 1936 ; Nofhofylenchus Thorne, 1941, and Dipfenchzzs Khan, Chawla & Seshadri, 1969. Parangzzinu Kirjanova, 1955 and Cynipcznguincz Maggenti, Hart & Paxman, 1974 are synonymised wit.h Angzzinn.

Les genres de la famille des Anguinidne (Netnafoda : Tylenchida) L’auteur redéfinit la famille des Angzzinidae ; celle-ci comprend les genres Anguina Scopoli, 1777, Noflzangzzinn Whitehead, 1959, Afrina g. nov., Orrina g. nov., Szzbanguina Paramonov, 1968, Dif~lenchzzs Filipjev, 1936, Nofhofylenchus Thorne, 1941, et. Dipfenchus Khan, Chawla 62 Seshadri, 1969. Paranguznn Kirjanova, 1955 et Cynipanguina Maggenti, Hart & Paxman, 1974 sont c.onsidérés comme synonymes mineurs d’Anguinn. Anguinn poophila Kirjanova, 1952 est synonymisé avec A. ngrosfis Steinbuch, 1799. Nofhtrngzzinn cecidoplasfes Goodey, 1934 est. la seule espèce retenue dans le genre Nofhanguina. Nofhangzzina phyllobin Thorne, 1934 devient l’espèce type d’Orrina g. nov. Afrinn g. nov. comprend A. hypnrrheniae (Corbett, 1966) comb. nov. et A. fzzmefczciens (Cobb, 1932) comb. nov. Dix-sept espkces appartenant aux genres dngzzina ou Paranguinu sont. transférées au genre Szzbanguina. A l’int&ieur des Anguinidae la complexité de la structure de la gonade femelle parait être en relation avec le degré d’adaptat,ion au parasitisme.

Paramonov (1962) considered t!he Anguininae and when they regarded Subanguina a subfamily of , and c.haracterised as synonymous with Anguina. In 1974, the new this subfamily by the large number of oogonia genus Cynipanguina Maggenti, Hart & Paxman, and sexual dimorphism. He included the genera 1974, was proposed. Anguina Scopoli, 1777, Paranguina Kirjanova, Siddiqi (1971) recognised the subfamilies 1955, and Nothnnguina Whitehead, 1959. Later Anguininae, Pseudhalenchinae and Syc.hnot,y- on, the genus Subangnina Paramonov, 1968, chinae within t.he Anguinidae. However, Geraert was added. While recognising close afflnities and Kheiri (1970) studied the two known between Anguina and Dit,ylenchus Filipjev, 1936, of PseudhaZenchus Tarjan, 1958, and found that Paramonov (1962, 1970) placed the latter in P. nzinutus, t.he type species, is closer to Tylen- Tylenchinae. Wu (1967) found it difflcult to chus Bastian, 1865 s. 1. than to Ditylcnchrzs. separate these two genera and redefined both Golden [1971) proposed the new subfamily on the basis of t,he length of crustaformeria in Ditylenchinae to ac.comodate Ditylenchus, Pserrd- relation to the length of spermatheca. Choi and halenchus and Diptenchus, while in the Angui- Loof (1973) also discussed the status of Anguina ninae he included Anguina, Paranguina and
