Abdomen : 555-684 (623)1* l° n g an d 388-418 (410)0. wide. Abdominal setae on each side : 

 Dorsal setae 4-9 on segments I and II, 4-7 on segments III and IV, 3-6 on segments V to VII, 

 and 2 on segment VIII, including one slightly longer seta. Pleural setae 3-4 on segment I, 

 4-5 on segments II to VI, and 3-4 on segments VII and VIII, including one very long seta 

 on the latter segment (107-137, av. n6u). Ventral setae 1-2 on segment II, usually 3 on 

 segments III to VII (sometimes 2 on segments III and IV, or 4 on segments IV and VII), and 

 1 on segment VIII. 



Glandular pouches very small ; setae of glandular pouch only include a pair of comparatively 

 short tail setae, 40-82 (64) u. long, the ratio their length to the total length of body being 

 1 : 17-1-34-9 (20-8). Genital segment typical of G. spuria ; genital capsule 146-171 (162)0. 

 long and 113-122 (119)0. wide, the ratio being 1-3-1-5 (1-4) : 1, and the ratio its length to the 

 total body length 1 : 7-8-9-8 (8-5). Anal opening 18-24 ( 22 )l* m diameter. Setae of genital 

 segment on each side : Dorsally two relatively long setae present near the base of the style ; 

 ventrally 7-9 (7-8) smaller setae occur on the genital capsule. 



Material : 10 specimens examined, collected by G. Matesova on Salix sp., in 

 Alma Ata, Kazakhstan, U.S.S.R., 2.iv.i95i. 



Remarks : This species, although very closely related to the brachypterous males 

 of G. spuria, can be distinguished mainly by the absence of the capitate sensory 

 setae on the antennal segments ; other minor differences are the acquisition of 

 more numerous abdominal setae and longer anal lobe seta. 



PSEUDOCHERMES Nitsche, 1895 



Pseudochermes fraxini (Kalt.) 



(Text-fig. 52) 



The apterous forms only known ; these are degenerate, and appear like the nymphal forms. 

 The males dorso-ventrally flattened, moderately robust and spindle-shaped, i.e. the body 

 broadest at mesothorax and gradually becoming narrower posteriorly ; the body ridges and 

 sclerites absent or greatly reduced. A comparatively very small species, with very short 

 antennae and legs ; mounted specimens 518-658 (602)0. long and 196-238 (210)0. wide at 

 mesothorax. 



Body setae : Antennae with very few fleshy and hair-like setae, 9-1 2 o. long ; the body with 

 sparse, slightly smaller hair-like setae only. 



Head : Intimately fused with thorax ; head ridges entirely absent. Eyes represented by 

 weakly sclerotized lateral spots, 89-95 (9 2 )! 1 apart. Cranial apophysis vestigial, apically 

 bifurcate. Mouth opening situated on a small, double-bulging mouth tubercle posteriorly. 

 Dorsal head setae 3-4 (3-8) and ventral head setae 2-3 (2-8) on each side of the median line. 



Antennae : Neither filiform nor moniliform, with segment VI distinctly widest of all flagellar 

 segments ; normally 8-segmented, but sometimes fusion between adjacent segments occurs ; 

 146-174 (162) u. long, i.e. much shorter than half the body length, the ratio 1 : 3-5-3-9 (3-7), 

 and slightly shorter than the hind legs, the ratio 1 : 1-1-1-2 (1-17). Scape 18-24 ( 2 °)v- l° n g
