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

ANNALES HISTORICO-NATURALES MUSEI NATIONALIS HUNGARICI Tomus VIII. Series nova 1957 The Genera of the Subfamily Monodontomerinae (Hym. Chalcidoidea) By G. SzELÉNYi, Budapest Introduction Monodontomerus, tin first genus of the subfamily I intend to deal with in the present paper, was described by W e s t w o o d as early as 1833. The second contribution was made by Förster in 1856, who erected three genera viz. Lochites, Crypto pristus and Olyphomerus, Further contributions were made in 1874 by Ma y r, describing the genus Holaspis, and in 1885 publishing the description of the genus Plesiostigma. The Monodontomerinae as a particular subfamily of the Torymidae was established by Ashmead in 1904 based on the genera mentioned above, and on Plesiostigmodes and Hemitorymus described by him simultaneously (comprising also Physothorax described by M a y r in 1885. and Websterellus described by Ashmead in 1893 ; the latter one, however, proved to be synonymous with Cryptopristus Forst., the former one belongs, according to our present knowledge, to the subfamily Toryminae, while Hemitorymus has been synonymized by H u b e r. 1927. with Tory m u s). The same degree of our knowledge was put out by Schmiedeknecht in 1909, who followed on the whole A s h m e a d's work, but treating Lochites erroneously as a Torymine genus. In 1907 published Craw f o r d a key of the genera of Monodontomerinae accounting tor 12 genera, and describing simultaneously the genera Ditropinotus, Eridontomerus, and the genus Microdontomerus for Torymus anthonomi Crawf. Again the same author issued a second paper in 1914 describing the genera Idiomacromerus, Antistrophoplex and Zaglyptonotus, and presenting a second generic key of already 17 genera. Dimeromicrus and Perissocentrus having been described by him earlier (1910). Both keys of Crawford included the above mentioned three genera settled erroneously in this subfamily or taken incorrectly for valid genera. The number of the valid Monodontomerine genera in the keys of 1907 and 1914 is therefore 9 and 14, respectively. Further contributions were made to our knowledge of this subfamily by G i r a u 11, who described in 1913 Amonodontomerus, in 1915 Proplesiostigma and Ditropinotella, and in 1920 Diplesiostigma. In 1914 described Gahan the genus Liodontomerus. Masi established in 1916 the genus Didactyliocerus and in 1921 Paraholaspis, changing at the same time the generic hame Holaspis Mayr in Pseudolorymus, and shortly after his Paraholaspis in Plastotorymus, both generic names having been preoccupied. In 1927 erected H u b e r the Monodontomerine genus Platykula for Syntomaspis albohirta Ashm. and Boucek described but recently his interesting genus Slanecia. A generic key of the Monodontomerinae was made by Ruschka in 1923 comprising the 10 Palaearctic genera only, erecting at the same time his Exopristus and including in this group the genus Lochites too. The revision of the Palaearctic Monodontomerinae made by Hoff meyer in 1931 offers no further data on this subject. In her monograph on the Chalcid flics of the Soviet Union. 1952. Nikolskaja deals with 12 genera treating also ones, which have so far not been recorded from the territory in question, but whose occurrence may be supposed. Her synopsis includes all Palaearctic genera known till then, except Didactyliocerus Masi, recording also the occurrence of Ditropinotus Crawf. in Central Asia for the first time. She was also the first author who recorded as early as in 1932 and 1934 the Nearctic species of Liodontomerus from the Palaearctic Region,
