LUZULASPIS 



Luzulaspis luzulae (Dufour) 



(Text-figs. 27 and 28) 



Living specimens light reddish brown ; short, slender, with comparatively long antennae and 

 short legs ; with many setae on the body and appendages. When mounted, total body length 

 1020-1290 (average 1141) \x ; width at mesothorax 240-270 (average 255) \i. Wing expanse 

 2090-2350 (average 2213) \l. 



Head subcorneal in dorsal view ; in lateral view flat, not obliquely elongated dorsoventrally, 

 anterodorsal bulge not pronounced ; length from apex to pronotal ridge 148-179 (average 164) 

 \x, width across genae 167-182 (average 175) jji. Median crest sclerotized, distinctly polygonally 

 reticulated, with 7-10 (average 8-7) hair-like dorsal head setae. Midcranial ridge dorsally 

 absent ; ventrally reduced to a shorter or longer median bar with lateral arms, surrounding 

 area not sclerotized, but showing distinct polygonal reticulation. Genae large, weakly sclero- 

 tized, with distinct polygonal reticulation ; without setae. Eyes : two pairs, small, subequal . 

 corneae of dorsal eyes 14-17 (average 15) \i in diameter and 40-4-5 (average 42) times as much 

 apart ; those of the ventral eyes 15-20 (average 16) jx in diameter and 2-2-2-5 (average 23) 

 times as much apart. Ocellus small. Ocular sclerite well sclerotized, distinctly polygonally 

 reticulated throughout. Preocular ridge long, the ridges of each side ventrally meeting or 

 almost meeting each other medially. Postocular ridge well developed, but tapering dorsally. 

 fnlerocular ridge broadly joining pre- and postocular ridges below ocellus. Dorsal ocular setae 

 absent. Ventral head setae : 11-30 (average 25) f.s. and 6-16 (average 10) h.s., arranged in a 

 broad band on anterior part of ocular sclerite, frequently with some (0-6, average 2-6) f.s. 

 occurring in the area anterior to the sclerite and occasionally with a seta just behind anterior 

 level of eyes ; a pair of median h.s. in the middle of the band distinctly longer than the rest.
