ORIBATOIDBA SINENSIS I 



ARTHUR PAUL JACOT 

 Shantung Xtian University 



Under the above title the writer purposes to report, from 

 time to time, what he is able to find on this subject. As far 

 as he knows, nothing has yet been reported on this group of 

 Acarina from China proper. 



The generic name Oribata originated with the French 

 entomologist Pierre Andre Latreille when in 1802, in his 

 " Histoire Naturelle, Generate et Particuliere des Crustaces 

 et des Insectes," Vol. 3, p. 65, he coined this term (as 

 explained by him in the " Nouveau Dictionnaire d' 'Histoire 

 Naturelle," Vol. 16 (1803), pp. 349 and 350) for the distin- 

 guishment of all those acarians which are now placed in the 

 family Oribatidae (sensu lato), establishing as type Acarus 

 geniculatus Linne. Two years later (1804) Frederic-Louis 

 Hammer published the '' Memoire Apterologique " of Jean- 

 Frederic Hermann (finished and edited by his father Paul 

 Hermann because of the early death of his son). Herein 

 Hermann formed the new generic name Notaspis for those 

 types of acarians which are now placed in the family 

 Oribatidae. Thus Notaspis is a synonym of Oribata. 



No new generic names fcr this group of arachnids 

 appeared until 1826 when Heyden in Vol. 18, p. 608 of 

 Oken's "Isis," wrote his " Versuch einer systematischen 

 Eintheilung der Acariden" in which he makes a detailed 

 subdivision of the acarians, applying generic names to each 

 of the subdivisions and appointing a type for each. From 

 this work I translate as follows : 



Family Acarides. 



Legion I. With eight legs adapted for running. 

 Phalanx 2. Without eyes. 



Section 2. Mouth parts on the under side of the body. 

 Division 5. Head and thorax grown together, 

 b. AD feet provided with club-shaped joints. 

 45. Genus, Oribata Latr. (Notaspis Herm.) 

 Type, Oribata geniculata Latr.
