Szelényi, G.: The genera of the subfamily Monodontomerinae (Hym. Chalcidoidea)

not being tongue-shaped and not narrowing towards the apex. Generotype : Liodontomerus Balási Szel. Owing to the fact that since A s h m e a d's work no generic key has been made comprising the genera orbis terrarum, I think, a such key will not be inappropriate. I endeavoured to compile, on the basis of the literature, the full amount of the genera known till now, it is doubtless, however, that the present paper will constitute a sort of frame-work only. There may be some genera the description of winch escaped my attention owing to the difficulties in acquiring literature, and a synopsis appropriate in every respect could have been made only by the means of a careful examination of the type species of these genera. I hope, however,, that this work may present a modest contribution to our knowledge of this interesting subfamily of the Torymidae. Some of the characteristics used in the key, for example the presence or lack of the carina around the occipital margin as well as that of the median carinae on the propodeum, seem to be hardly reliable as generic differences. In some cases they may be developpcd weakly, especially in male specimens. The validity of some genera is, therefore, to some extent doubtful. A generic key of the Monodontomerinae 1 (2) Abdomen petiolate, scutellum with a cross-furrow before apex, antennae 12-jointed, with one ring, five funicle- and four club-joints ; posterior femora simple, (South Australia): Amonodontomerus Git. 1913 (Type : A. viridis Git.) 2 (1) Abdomen sessile. 3 (6) Pronotum longer than the mesoscutum, scutellum with a cross-furrow. 4 (5) Front femora much swollen ; antennae with two ring joints (South America) : Plesiostigmodes Ashm. 1904 (Type : P. brasiliensis Ashm.) 5 (4) Front femora normal, antennae with one ring joint, (South America) : Plesiostigma Mayr, 1885 (Type : P. bicolor Mayr) 6 (3) Pronotum generally much shorter than the mesoscutum, if of the same length, scutellum without a cross-furrow. 7 (8) Front femora much swollen, pronotum by far as long as the mesoscutum, scutellum without cross furrow, posterior femora with small teeth, (NS Wales): Macrodontomerus Git. 1913 (Type : M. unimaculatus Git.) 8 (7) Front femora slender (at most in male specimens of Liodontomerus distinctly swollen), pronotum much shorter than the mesoscutum. 9 (12) Antennae with three or more ring-joints, that is, the first funicle joint or more of the funicle joints remarkably reduced ; occiput immargined. 10 (11) Hind femora thickened, with a row of small teeth, the three proximal funicle joints ringlike, club much shorter than the funicle ; first and second abdominal tergites tongue-shaped, long, narrowing toward the apex, (Europe): Slanecia Bck. 1955 (Type : 5. elongata Bck.) 11 (10) Hind femora slender with the lower margin smooth, the four proximal funicle joints ringlike, club as long as or even longer than the whole funicle ; first and second abdominal tergites not tongue-shaped, transverse, not narrowing toward the apex, (Europe) : Lochimerus gen. nov. (Type : Liodontomerus Balási Szel.)
