SYNOPSIS 



Prior to this revision, the subfamily Leptocorisinae Stal contained eight genera and thirty 

 eight species, including major rice pests of the Far East. There was confusion over the identities 

 of many species and since Stal (1873) no world-wide revisional work had been undertaken and in 

 his work only fourteen species (including some synonyms) were covered. 



During the present study, three new tribes, one new genus, two new subgenera, nineteen new 

 species have been described and one species, because of its homonymy, has been renamed. 

 Stenocoris Burmeister (1839) (subgenus sensu Stal, 1873) has been given generic rank and has 

 been separated from Leptocorisa Latreille, 1829. Rhabdocoris Kolenati, 1845 (subgenus of 

 Leptocorisa Latreille sensu Stal, 1873) has been synonymized with Leptocorisa. The undescribed 

 mis-identified type-species of the subgenus Erbula has been renamed and described. Nine 

 previously described species have been considered synonyms, whilst four species regarded as 

 synonyms by earlier workers have been reinstated. 



INTRODUCTION 



Leptocorisinae Stal is a subfamily of the coreoid family Alydidae and contained, 

 prior to the present revision, eight genera and thirty eight species, including a 

 number of important rice pests of the Indochina, Malaya and Australian Sub- 

 regions. 



In the whole subfamily, there has been confusion and uncertainty over the identi- 

 fication of species. For example, China (1930), in " Insects of Samoa and other 

 Samoan terrestrial Arthropoda ", expressed his doubts on the specific identity of 

 Noliphus discopterus Stal and stated that perhaps it was a local race of N. insularis
