102 I. AHMAD 



The range of this, possibly rather rare, species extends in the west into Ceylon 

 and in the east into south east Borneo. The adults have been collected in January. 

 This species has also been collected at light in Malaya (Selangor State). 



This species is close to L. lepida Breddin and L. luzonica sp. n., but can easily be 

 separated from them by its short, thick, curved and pointed paraclypeae (Text-fig. 

 329). In aedeagus, its elongated, ventral thecal appendages (Text-fig. 221, D), long 

 and straight second right lateral conjunctival appendage (Text-fig. 221, F) and in the 

 2 the deep emarginate posterior margin of seventh abdominal sternum (Text-fig. 333) 

 are its peculiarities. 



Leptocorisa sakdapolrakae sp. n. 



(Text-figs. 210, 224, 238, 252, 266 and 336-341) 



Characterized by short but cylindrical and pointed paraclypeae, long rostrum, 

 which extends well beyond the apices of second coxae and by the form of the <J and 

 2 genitalia.

 Hind tibia, 6-0-7-3 mm. Distance between ocelli, 0-4-0-46 mm., distance between an ocellus 

 and an eye, 0-73-0-8 mm. 



Body slim, light brown, tinged with black. Head short ; occipital suture " V "-shaped in 

 middle ; paraclypeae short, cylindrical, thicker at base and pointed at apices. Antennae 

 brownish black with basal segments palish brown, apices black, second, third and fourth seg- 

 ments only pale at their bases. Rostrum long, extending well beyond apices of second coxae. 

 Lateral black line, extending from sides of antenniferous tubercles on to collar. Pronotal disc 

 pale, sometimes with greenish tinge posteriorly. Legs usually black, pale near articulations. 

 Hemielytra pale, slightly dark. Posterior margin of seventh abdominal tergum medially 

 convex, pygophore elongated, with thin lobes of ninth segments (Text-fig. 336). 



o" genitalia : Claspers in dorsal view, extending beyond posterior margin of pygophore 

 (Text-fig. 336) ; apices truncated (Text-fig. 210) ; both dorsal and ventral pairs of conjunctival 

 appendages present, ventral asymmetrical (Text-fig. 337) ; left lateral conjunctival appendage 

 strongly curved in middle and acutely pointed at apex (Text-fig. 224, E) ; frontal conjunctival 

 appendage with two sclerotized pieces (Text-fig. 224, A) ; two right lateral conjunctival append- 

 ages as in Text-fig. 338 ; second long, strongly curved in middle and acutely pointed (Text-fig. 

 224, F) ; membranous appendage with a trinagular terminal and a bilobed dorsal appendage 

 (Text-fig. 338). 



$. Very similar to <J in general appearance and measurements, highly variable in size ; 

 posterior margin of seventh abdominal sternum emarginate, with a small convex median 

 projection (Text-fig. 339). 



$ genitalia : First gonocoxae elongated, outer margin sinuate, apices rounded (Text-fig. 

 252) ; fourteen pairs of intervalvular sacs (Text-fig. 340) ; spermatheca comparatively very 

 short, elongated with a transverse neck, a median flange and a long coiled tube (Text-fig. 238).
