REVISION OF COELIDIINAE 5 



Distant grouped the many tropical forms of the near east Jassinae on the 

 basis of gross head characters and proposed several divisions (tribes) to deal with 

 the genera, many of which he described as new. Two divisions, the Thagriaria 

 and Jassusaria, were proposed to accommodate five and eight genera, respectively, 

 seven of which are applicable to Coelidiinae. Baker, dissatisfied with Distant's 

 arrangement, combined the groups, then added 10 genera from other regions of 

 the world and placed them all under one section (tribe), Jassaria. Among 23 

 genera thus treated, 12 are applicable to Coelidiinae. 



China & Fennah (1945) discovered that the type-species of Iassus Fabricius 

 (for many years incorrectly spelled Jassus) and Bythoscopus Germar were conspccific, 

 thus necessitating a selection of the next available name to accommodate the 

 genus Jassus sensu Germar, 1833 et auct. Although these authors selected 

 Coelidia Germar, 1821 as the next available name and designated Coelidia venosa 

 Germar as the type-species, Kirkaldy (1901) and Oman (1936) had previously 

 fixed the type of Coelidia. 



Evans (1947) contributed much to the development of the present classification 

 when he relegated 29 pantropical and three holarctic genera to the group. Oman 

 (1949) and Linnavuori (1959) recognized the subfamily and added important 

 genital characteristics to the classification. Metcalf (1964) listed all of the known 

 tribes, genera and species of Coelidiinae under the family Coclidiidae, giving 

 subordinate recognition to the subfamilies Neocoelidiinae and Tartessinae, neither 

 of which is closely related to Coelidiinae. 



The Tinobregmini was recently established by Oman (1949) to accommodate 

 one genus of the Nearctic Region. Metcalf (1964) recognized the grouping and 

 listed 11 species and subspecies. 



DeLong (1945) proposed the tribe Sandersellini for the monobasic genus 

 Sandersellus. Equal recognition was given by Metcalf (1964). 



The tribe Tharrini is here proposed to accommodate a very large genus, Tharra, 

 and two new genera, Neotharra and Haranthus, thus removing Tharra from 

 Jassaria of Baker (1915) and from Coelidiini, placed there by Metcalf (1964). 

 The unique combination of head characters and bipendulate aedeagus has resulted 

 in considerable chresonymy and greatly broadened the geographical range of 

 the group. 



MORPHOLOGY 



The subfamily Coelidiinae embraces such a diversity of forms that it is not 

 possible to generalize upon any given morphological feature of the group. Thus, 

 it is necessary to remind the reader that the many exceptions that are evident 

 are being dealt with in more detail at the generic and specific levels. 



A favourable attribute of coelidiine leafhoppers is that the head bears gross 

 features that are useful for differentiating higher taxa as well as fine characters 

 for distinguishing many species. Similarly, the male genitalia, which form the 

 basis of the present classification, offer significant contributions at all taxonomic 

 levels.
