THE LEPTOCORISINAE OF THE WORLD 69 



the median longitudinal red line which runs on the ventral side of adbominal seg- 

 ments (but is sometimes only faintly represented) by the black anal and medial vein 

 of hemielytra and by the short paraclypeae, which are thicker at base and thinner at 

 apices.

 Rhabdocoris Kolenati, 1845 : 67 syn. n. 



Type-species : Cimex acutus Thunberg, 1783. 



Body robust. Head elongated but shorter than pronotum, ocelli placed close together. 

 Antennae with apices of basal segment slightly thicker. Rostrum usually short, touching 

 second coxae. 



In £, posterior margin of seventh abdominal tergum truncated ; pygophore rounded, claspers 

 crossed behind, made up of two components, shaft (or main stem) and blade (or bent portion) ; 

 aedeagus with both (dorsal and ventral) pairs of thecal appendages ; frontal conjunctival 

 appendage membranous with usually two or three sclerotized pieces ; membranous appendage 

 large, usually with a terminal and a dorsal appendage. 



In 9. posterior margin of seventh abdominal sternum emarginate, entire, without a fold or 

 split ; first gonocoxae large, conical in form ; intervalvular sacs at least four pairs ; sperma- 

 theca usually irregular, always with a median flange. 



This genus is close to Stenocoris Burmeister but can readily be distinguished by the 

 form of the claspers, which in Stenocoris consist of a single component and by emargin- 

 ate posterior margin of seventh abdominal sternum (which in Stenocoris is usually 

 with a median projection, indentation or split). These genera can also be separated 

 by the structure of aedeagus, for in Stenocoris the frontal conjunctival appendage is 

 usually sclerotized and supporting and terminal appendages are wanting. The 

 median flange of spermatheca of Leptocorisa is unique. The ranges of Leptocorisa 

 and Stenocoris are distinct, for Leptocorisa is confined to Oriento-Australian region 

 and Stenocoris is found in Ethiopian, Nearctic and Neotropical regions. From 

 Bloeteocoris this genus can be separated by its normal genae and by other characters 

 in the genitalia (see page 115). 



The preservation of the name Leptocorisa Latreille and the suppression of Lepto- 

 corixa Berthold are the subjects of an application to the International Commission 

 on Zoological Nomenclature (China and Ahmad, 1963).
