THE LEPTOCORISINAE OF THE WORLD n 



elongated ; claspers variable in form and position ; aedeagus usually with a ventral pair of 

 thecal appendages ; frontal conjunctival appendages usually present, sclerotised ; mem- 

 branous appendage short, usually without a terminal appendage but usually with a pair of 

 dorsal appendages. 



In $, posterior margin of seventh abdominal sternum either bilobed, medially produced, with 

 a short median split or concave with a median fold ; first gonocoxae usually large, and tri- 

 angular ; intervalvular sacs usually absent ; spermatheca usually flask-shaped, without a 

 median flange and usually with a long coiled tube. 



This genus shows some affinities with all the other genera in the tribe Leptocorisini 

 and indeed to Lyrnessus and Cosmoleptus sumatranus in Noliphini. It could possibly 

 be polyphyletic or have retained many of the characters of the more generalized 

 ancestral form. 



As Myodocha Burmeister nee Latreille was an erroneous identification as well as 

 an emendation of Myodocha Latreille, it is not necessary that the replacement name 

 Stenocoris Burmeister, 1839 should take the same type as that of Myodocha Latreille. 

 The latter is M. serripes Olivier, 181 1 (a Lygaeid) and has been so designated under 

 the Plenary Powers by the International Commission on Zoological Nomenclature 

 (1961, Bull. zool. NomencL, 18 : 287). Stenocoris is not a new name but is in fact a 

 new generic name for the taxon wrongly identified by Burmeister (1835). The type- 

 species of Stenocoris is one of the two species cited by Burmeister in 1835, i.e., 

 varicomis Fabricius, 1803 and tipuloides Degeer, 1773. It has been fixed by 

 Burmeister (1839) as Cimex tipuloides Degeer, 1773. 



Stenocoris was reduced to subgeneric rank within Leptocorisa Latreille, 1829 by 

 Stal. In fact Sta.1 misidentified Leptocorisa Laporte nee Latreille for Leptocorisa 

 Latreille. The most senior subgenus Stenocoris is therefore hereby proposed as the 

 generic name for the taxon. An application with Dr. W. E. China has been made 

 to the International Commission on Zoological Nomenclature for its recognition (1963). 



Key to Subgenera 



1 Claspers never crossed, when at rest parallel to one another (Text-fig. 19) ; posterior 



margin of 9 seventh abdominal sternum always medially produced (Text-fig. 22), 

 sometimes notched in the middle, never bilobed, concave or with a median split. 



ERBULA (p. 14) 



- Claspers crossed (Text-fig. 75) ; posterior margin of $ seventh abdominal sternum 



either bilobed (Text-fig. 82), concave (Text-fig. 15) or with a short median split 

 (Text-fig. 181) 2 



2 Claspers curved like an " S ", apex thick and truncated (Text-fig. 11) ; apical 



segment of antennae with at least basal half pale ; posterior margin of $ seventh 

 abdominal sternum concave with a median fold PSEUDOLEPTOCORISA (p. 12) 



- Claspers never curved like an " S ", apex always acutely pointed (Text-fig. 76) ; 



apical segments of antennae with small pale area at base, never extending to half 

 the length of the segment ; posterior margin of $ seventh abdominal sternum 

 never concave with a median fold ......... 3 



3 Posterior angles of pygophore acutely pointed ; claspers crossed over pygophore 



(Text-fig. 178) ; posterior margin of $ seventh abdominal sternum always with a 

 short median split ORYZOCORIS (p. 60) 



- Posterior angles of pygophore not acutely pointed ; claspers crossed in a socket 



(Text-fig. 75) ; posterior margin of $ seventh abdominal sternum always medially 

 bilobed, never with a split STENOCORIS (p. 30)
