side of the former, is composed of the fifth tarsal joint, which proximally 

 is more or less elongated, only in some Antconini is the fifth joint aljout 

 normal, without elongation; on the ventral side, that is, on the side 

 lying against the lateral chela arm, the median chela ann bears nmnerous 

 rows of hyaline diversely shaped lamella and bristles. The lateral 

 chela ami is slender, pointed, mostly saber-shaped, ventrally with or 

 without rows of lamellae and l)ristles, the medial chela arm usually so 

 rests that both ends cross; there is presented a strong, lengthened 

 claw; the other claw in contrast is reduced and wrapped around by 

 the lobes of the more or less strongly lengthened empodium. If the 

 fifth tarsal joint is much shorter than the proximal j^rocess, then both 

 chela anns are movable, whereby the morphological proximal end of 

 the fifth tarsal joint becomes apparently the distal end; in the contrary 

 case only the lateral chela joint is movable. Abdomen slightly depressed 

 from above, seldom latcralh' depressed together, second segment 

 somewhat bell-shaped, the following gradually shorter and smaller. 



Male: Generally the male is much smaller than the female, mostly 

 only half as long, the eyes are pubescent and almost half spherical, while 

 in the female they arc bare and oval. The pronotum of the male is not 

 \'isible from above, the hind angles of the pro thorax reach the tegulae 

 always in the male, while in the female they often do not, the parapsidal 

 furrows can be seen very plainly often extending across the mesonotum 

 in the male, while in the female they may be lacking. In Deinodryinus 

 the pterostigma is broad in the male and only moderately broad in the 

 female, in two other genera the veins of the basal cells are obliterated 

 in the male, while they appear well developed in the female, the legs 

 of the male are not long and slender as in the female, but short and 

 quite thick, the fore tarsus lacks the chela.
